Greyfeld Partners
We make yourcompany grow.
Greyfeld Partners is a boutique consulting firm that limits its portfolio to ensure each client gets our full operating capacity. We build revenue engines, AI systems, and go-to-market playbooks you own — then hand you the keys. We keep our client list small because diluting attention dilutes results. Our fees are tied to yours — we build for growth that compounds, not headlines.
We limit our portfolio to 4–5 active engagements at a time
Numbers that speak for themselves.
We limit our portfolio to 4–5 active engagements. Every client gets the full operating capacity of our senior team — not a diluted version of it.
McKinsey-caliber strategy. AI-powered systems. Founder-level execution. We embed in your team, build the system, hand you the keys — and the problem stays solved.
We've been in your shoes — building companies from scratch, raising capital, hiring teams, and staring at revenue charts that needed to go up and to the right. We started Greyfeld Partners because we saw too many brilliant companies fail not from lack of vision, but from lack of the right operational partner. Every engagement we take is personal. Your growth is our growth — a significant portion of our fees is performance-based, so our incentives are fully aligned with yours.
Why We Do ThisPricing, go-to-market, financial modeling, marketplace design, operational restructuring — every engagement gets the depth it deserves. We don’t spread thin. We go all-in on yours.
What We Do
The 10 highest-impact projects our clients hire us for.
We redesign your entire revenue engine — pricing tiers, packaging, monetization strategy, and unit economics — so every customer segment generates maximum margin. Built for companies preparing for their next raise or seeking profitability.
Processing $2B in annual volume but margins were collapsing quarter over quarter. The board was questioning the path to profitability.
Forensic analysis of 12,000 merchant accounts revealed that 68% of volume came from merchants on legacy pricing tiers negotiated during early growth — tiers that were now below cost-to-serve. The pricing architecture had never been redesigned post-scale.
Rebuilt the entire pricing architecture: introduced value-based tiers segmented by merchant size and transaction profile, designed a migration playbook with 90-day grandfather clauses, and implemented dynamic interchange-plus pricing for enterprise accounts.
Net revenue tripled in 14 months. EBITDA-positive 6 months ahead of plan. Merchant churn during migration was only 3.2% — well below the 12% industry benchmark.
“They forensically analyzed 12,000 merchant accounts and rebuilt our entire pricing architecture. Net revenue tripled in 14 months — and we hit EBITDA-positive 6 months ahead of plan.”
— CFO, Market-Leading Payments Platform (Series C, Southeast Asia)We identify where AI creates real competitive advantage in your business — not toy demos, but production systems that reduce costs, accelerate decisions, and create moats. From LLM integration to computer vision pipelines, we build what matters.
14-day claims resolution times and 32% customer satisfaction. The claims department was the company's biggest cost center and its worst customer experience.
Claims were being processed through a 23-step manual workflow designed in 2008. Every claim, regardless of complexity, followed the same path. Simple claims that could be auto-adjudicated were stuck behind complex ones in a single queue. Fraud detection was rule-based and catching only 12% of fraudulent claims.
Deployed an AI claims triage system that classifies claims by complexity and routes simple ones to auto-adjudication. Built a machine learning fraud detection model trained on 5 years of historical data. Redesigned the workflow from 23 steps to 7 for complex claims.
Resolution time dropped from 14 days to 4 hours for simple claims. Fraud detection jumped from 12% to 67%, saving $8.2M per year. The claims team was redeployed to advisory roles — zero layoffs.
“They deployed an AI claims processing system that cut resolution to 4 hours. Fraud detection jumped from 12% to 67%, saving us $8.2M per year. Zero layoffs.”
— COO, Top-5 National Insurance Provider (Latin America, 200+ employees)We design your market entry or expansion playbook — ICP definition, channel strategy, sales motion, and competitive positioning. Especially effective for companies entering new geographies or pivoting upmarket from SMB to enterprise.
Strong product with zero revenue. The founding team were clinicians, not salespeople. Two previous attempts to hire a VP of Sales had failed within 6 months each.
The product was being positioned as a general healthcare tool when the real demand signal came from a specific niche: telehealth platforms needing patient engagement features. The ICP was too broad, the messaging was clinical instead of commercial, and there was no structured sales process — just founder-led demos.
Identified telehealth platforms as the beachhead market through demand signal analysis. Built the entire sales playbook: ICP definition, outbound sequences, demo scripts, objection handling, and pricing. Hired the first 3 account executives. Designed a free tier that converts at 18%.
$0 to $4.2M ARR in 9 months. Raised a $12M Series A on the back of the traction. Free tier conversion rate of 18% — 3x the industry average.
“They identified telehealth platforms as our beachhead, built the entire sales playbook, hired our first 3 AEs, and designed a free tier that converts at 18%. We went from $0 to $4.2M ARR in 9 months.”
— CEO & Co-Founder, Healthcare SaaS Startup (pre-revenue to Series A)We build the data infrastructure that turns raw data into executive-grade insights — real-time dashboards, predictive models, and decision engines. From data warehouse architecture to self-service BI, we make your data actually useful.
400+ retail stores with data trapped in 7 different systems. The CEO couldn't see real-time unit economics. Board meetings relied on 3-week-old spreadsheets.
Each brand had been acquired independently and kept its own POS, ERP, and reporting stack. No one had ever unified the data layer. The finance team spent 80% of their time reconciling numbers across systems instead of analyzing them. Hidden margin leakage was invisible because no one could see cross-brand patterns.
Built a unified data platform connecting all 7 systems. Created real-time dashboards showing unit economics by product line, store, and brand. Deployed anomaly detection to flag margin leakage automatically. Trained the finance team on self-service analytics.
Identified $18M in hidden margin that didn't know existed. Inventory costs dropped 28%, markdown losses fell 41%. For the first time in 15 years, the CEO can see real-time unit economics by product line.
“They built a unified data platform that identified $18M in hidden margin we didn't know existed. For the first time in 15 years, our CEO can see real-time unit economics by product line.”
— COO, Multi-Brand Retail Group (400+ stores, Sub-Saharan Africa)We de-risk your international expansion with market intelligence, regulatory navigation, local partnership strategy, and operational setup. Specialized in US-LATAM and LATAM-US corridors, with deep networks across Brazil, Mexico, Colombia, and Argentina.
Failed twice to enter Brazil — regulatory complexity, wrong partners, and $3M burned with no sustainable foothold.
Both previous attempts used the same playbook that worked in the US: direct market entry with a local GM. But Brazil's logistics market requires specific tax structures (ICMS optimization), local fleet partnerships, and regulatory approvals that take 8-12 months. The US team was making decisions based on US assumptions about market speed and partner reliability.
Navigated the regulatory maze and secured all required approvals in parallel. Connected the company with vetted local fleet partners through our network. Designed a tax-optimized corporate structure. Built a phased market entry plan starting with São Paulo before expanding to 5 additional states.
Operational in Brazil within 5 months. $8M ARR in Latin America within the first year. The Brazil operation became the fastest-growing geography in the company's portfolio.
“They navigated the regulatory maze, connected us with the right local partners, and had us operational in 5 months. We hit $8M ARR in Latin America within the first year.”
— CEO, US Logistics Platform (Series B, expanding to LATAM)We audit your operations end-to-end, identify the 20% of processes causing 80% of waste, and build automation that actually works — from workflow redesign to custom AI tooling. Average client saves 35% on operational costs within 6 months.
$120M GMV marketplace with an order-to-cash cycle that required 47 people. Error rates were climbing, and the operations team was the company's largest cost center.
The order-to-cash process had been built incrementally over 6 years with no architectural review. It involved 23 manual handoffs between 5 different systems. Each handoff introduced a 2-4% error rate that compounded through the chain. The team had grown to manage errors, not to prevent them.
Mapped the entire order-to-cash flow and eliminated 16 of 23 handoffs through system integration and automation. Built custom middleware connecting the 5 systems. Deployed AI-powered exception handling for the remaining manual touchpoints. Retrained the team for oversight and escalation roles.
Team reduced from 47 to 12 people (all retained in new roles). Error rates dropped 90%. Processing capacity tripled. The ROI was visible within the first quarter.
“They automated the entire order-to-cash process — now it takes 12 people instead of 47, error rates dropped 90%, and we're processing 3x the volume. The ROI was visible within the first quarter.”
— VP Operations, Leading E-commerce Marketplace ($120M GMV, Latin America)We prepare your company for investor scrutiny — financial model stress-testing, unit economics validation, competitive positioning, and board-ready materials. Also provide buy-side due diligence for PE firms and family offices evaluating targets.
Failed two previous fundraising attempts at the term sheet stage. Strong operational metrics but investors kept passing after reviewing the data room.
The financial model was top-down with unrealistic growth assumptions. Unit economics were presented at the aggregate level, hiding that 2 of 4 customer segments were unprofitable. The data room was disorganized — investors were spending more time finding information than evaluating it.
Rebuilt the financial model from scratch with bottoms-up cohort analysis and segment-level unit economics. Created three scenario cases (base, bull, bear). Restructured the data room into an investor-friendly format. Coached the C-suite through 30+ investor meetings.
Closed the Series C at 3.2x the Series B valuation. The lead investor said the data room was 'the best we've ever seen.' Round was oversubscribed by 40%.
“They rebuilt our financial model from scratch. Our lead investor at the Series C said the data room was 'the best we've ever seen.' We closed at 3.2x our Series B valuation.”
— CEO, Two-Sided Marketplace (Series C, $190M pre-money valuation)We redesign your sales organization from the ground up — territory planning, compensation structures, pipeline management, and CRM optimization. We've built sales teams that consistently hit 140%+ of quota across SaaS, fintech, and enterprise services.
$60M ARR with a sales team closing $45K deals when the product could support $200K contracts. Revenue growth had stalled despite a strong product and growing market.
The sales team was structured for volume, not value. Territory assignments were geographic (not strategic), the comp model rewarded deal count over deal size, and the qualification framework didn't distinguish between $45K and $200K opportunities. Reps were taking the path of least resistance — closing small deals fast rather than building large ones.
Restructured the entire sales motion: territory mapping based on account potential, redesigned comp model to reward ACV, built a qualification framework that routes large opportunities to specialized enterprise reps, and created a deal desk for complex pricing.
Average deal size went from $45K to $180K. Revenue grew 40% in two quarters. Same team, completely different results. The enterprise segment now represents 55% of new ARR.
“They restructured our entire sales motion — territory mapping, comp model, qualification framework. Average deal size went to $180K. Same team, completely different results.”
— CRO, B2B SaaS Platform ($60M ARR, North America)We align your product roadmap with revenue goals — feature prioritization based on willingness-to-pay data, competitive gap analysis, and build-vs-buy decisions. Especially valuable for companies with product-market fit seeking product-led growth.
200K users but flat revenue. The engineering team shipped 40+ features per quarter but none moved the revenue needle. Core ICP customers were churning at 8% monthly.
The roadmap was driven by feature requests from the loudest customers — who happened to be edge cases, not the core ICP. The 3 features that the core ICP actually needed (collaborative workspaces, progress analytics, LMS integration) had been deprioritized for 4 consecutive quarters. The team was building for retention of the wrong segment.
Killed 60% of the roadmap. Refocused the team on the 3 high-value features the core ICP needed. Redesigned pricing around those features to create natural upgrade paths. Built a feature prioritization framework based on willingness-to-pay data from 150 customer interviews.
Core ICP churn dropped from 8% to 1.9% monthly. Revenue grew 67% in 6 months. The 3 features became the primary reason new customers cited for purchasing. Engineering velocity actually increased because the team was focused.
“We were shipping 40 features a quarter and none of them mattered. They killed 60% of our roadmap and focused us on 3 things. Revenue grew 67% in 6 months.”
— CPO, Series B Edtech (200K users, North America)We modernize legacy enterprises — from technology stack migration to organizational change management. Not just new software, but new ways of working. Designed for companies with $100M+ revenue that need to move at startup speed without startup risk.
$200M revenue company losing market share to digital-native competitors. Online orders were 3% of revenue while the industry average had moved to 35%. The sales team saw digital as a threat to their commissions.
Two previous digital transformation attempts had failed because they were technology-first, not people-first. The sales team actively sabotaged the e-commerce platform because it threatened their compensation. The catalog wasn't digitized — 60,000 SKUs existed only in paper catalogs and the sales team's memory. Without the sales team's buy-in, no technology could succeed.
Started with the people, not the technology. Redesigned the comp model so sales reps earned commission on digital orders from their accounts. Digitized the 60,000-SKU catalog with the sales team's help (they became the subject matter experts). Built the e-commerce platform as a tool FOR the sales team, not a replacement. Deployed in phases: first as a quoting tool for reps, then as a self-service portal for customers.
Digital orders went from 3% to 42% of revenue in 18 months. Average order value increased 23% because the platform suggested complementary products. Sales team productivity doubled — they handled 2x the accounts with the same headcount. Market share recovered and grew 8 points.
“Two previous digital transformations failed because they fought the sales team. This one succeeded because it made the sales team more powerful. Digital went from 3% to 42% of revenue.”
— CEO, Century-Old Industrial Distributor ($200M revenue, Latin America)Boutique by choice.
“We deliberately limit our portfolio so every client gets the depth of attention that drives outsized results. We don't compete on scale — we compete on the value we create inside each engagement.”
Skin in the Game
Our economics are tied to yours. A significant portion of our fees is linked to measurable results — so our incentives are fully aligned with your growth. We invest in your success because we build for growth that compounds, not headlines.
Operators, Not Theorists
Every partner has built and scaled companies from zero. Across 40+ engagements, we've engineered 23 revenue systems and deployed 50+ AI solutions — all designed so clients own and operate them independently. We share what we've scaled, not what we've read.
Solutions You Own, Not Slide Decks You File
Other firms hand you a slide deck and an invoice. We solve the critical growth problem first, then build the system your team owns and evolves — no vendor lock-in, no dependency on us. We sit in your war room, diagnose the bottleneck, design the fix, write the code, build the model, and leave only when the engine runs without us. You keep everything. We make ourselves unnecessary.
Radical Transparency
We'll tell you what's broken before we tell you what we can fix. No sugarcoating, no filler reports. Just the truth and a plan to act on it.
Expert-Validated, Client-Authorized
We validate our recommendations and implementations with a curated network of senior specialists — world-class operators with 15+ years at institutions like McKinsey, Goldman Sachs, MIT, and Google. Nothing leaves our hands without expert review, and no external specialist sees your data without your explicit written authorization. Every member of our network is bound by NDA. Your information is safe — always.
Strategy firms advise. Dev shops build. We do both — and own the outcome.
Most companies hire strategy consultants who leave behind a deck, or dev shops that build what they're told. Neither is accountable for revenue. We are.

Book a Fit CallTrusted by operators who build.
I first started working with the Greyfeld team in San Francisco during their Y Combinator batch. Through my experience covering Alibaba and other global consumer marketplaces, I quickly switched from a skeptic to a strong believer in their vision. The team's industry acumen, work ethic, engineering foundation, and intrinsic motivations are archetypal founder traits for this market. Few executives in this industry have their direct, prior marketplace experience or have built a truly differentiated and efficient business model that has the ability to scale globally.
Every client gets the full team. That's the point.
Because we limit our portfolio, we can do what larger firms can't: embed our senior partners directly in your business — backed by a curated network of world-class domain specialists, engaged only with your explicit authorization.
Strategic Management Consulting
Our team embeds in your leadership as fractional CRO, COO, CPO, or VP Growth. You get McKinsey-caliber strategy with founder-level execution — powered by AI. We design systems your team owns forever: revenue engines, AI automation, and growth playbooks built on 50+ proven solutions we've already deployed.
Strategic Advisory
Ongoing strategic counsel for founders and C-suite executives ready to scale — navigating growth, fundraising, or market expansion. Backed by proprietary AI analytics.
Project-Based Engagements
Tailored, scoped projects designed to scale specific revenue levers — pricing strategy, go-to-market plans, financial modeling, marketplace design, or operational restructuring. Each project builds on our library of proven solutions.
The operators behind the work.
Greyfeld Partners was founded by two operators who chose to build a firm where quality of work matters more than quantity of clients. Over a decade together, they've engineered 23 revenue systems, deployed 50+ AI solutions, and led teams across 12 countries. They are supported by a curated network of senior domain specialists — world-class operators with 15+ years at institutions like McKinsey, Goldman Sachs, MIT, and Google — engaged only with explicit client authorization and bound by NDA. Every engagement gets their direct, personal involvement — not a junior team with a partner's name on the cover.
Diego Fischer
Co-Founding & Managing Partner — Strategy & Revenue
Diego doesn't advise from the sidelines — he builds. He took InstaCarro from a whiteboard idea to $105M in revenue in 2.5 years, delivering a 20x return to investors and creating Brazil's largest consumer-to-business car marketplace. When he saw the same playbook could work again, he co-founded Carupi through Y Combinator (W20), raised $11M, and grew revenue 8x. Across both ventures, he led over 500 people and built the revenue engines that now form the foundation of every Greyfeld engagement. His instinct for finding money inside a business was sharpened at Goldman Sachs, Credit Suisse, and McKinsey — and refined at MIT Sloan, where he graduated with a perfect 5.0 GPA and won first place in both the Advanced Analytics competition and the t=0 Startup Hackathon.
“Diego restructured our entire go-to-market in 90 days. Revenue went from flat to 340% growth in two quarters. He didn't just advise — he sat in our war room and rebuilt the engine with us. The financial model he built is still the backbone of every board presentation we give.”
Onil Pereyra
Co-Founding & Managing Partner — Technology & AI
Onil is the engineer who turns strategy into systems that scale. He architected the technology behind InstaCarro — the platform that processed billions in car transactions and became Brazil's #1 consumer-to-business marketplace. Then he founded Curbo, scaling it across 3 countries, $114M in transactions, and 300 people, building the top-performing used car marketplace in northern Latin America. Over 15 years, he's developed an instinct for turning complex technical challenges into revenue-generating platforms — a skill he refined as VP of Operations at Fusemachines, where he led AI deployment at enterprise scale. Today, every AI system and automation Greyfeld deploys carries his architectural fingerprint. MSc in Project Management from Université du Québec.
“Onil deployed an AI system that replaced a 40-person manual review team — not by cutting corners, but by building something genuinely better. Error rates dropped 94%, processing time went from days to seconds, and the system paid for itself in three weeks. I've never seen an engineer think so clearly about business impact.”
What makes a boutique firm different
We work with ambitious executives and entrepreneurs building the next great company and established businesses ready to scale. Whether you're doing $1M or $500M in revenue, our sweet spot is companies that know they need to grow but haven't yet built the systems to do it efficiently. We work across four pillars: (1) Strategy & Go-to-Market — pricing, positioning, and revenue architecture; (2) Product & Technology — AI systems, automation, and platform engineering; (3) Operations & Processes — workflows, risk management, and organizational design; and (4) Financial Infrastructure — modeling, fundraising, and capital strategy. Industries include tech, marketplaces, SaaS, fintech, and consumer.
Greyfeld Partners operates as a strategic management consulting firm with fractional executive capabilities. We deploy senior operators across any function your company needs — from CRO and COO to CFO, CTO, CMO, CPO, or Chief of Staff — covering strategy, finance, technology, operations, risk management, marketing, and beyond. We engineer profitable growth through revenue architecture, pricing strategy, financial modeling, product development, go-to-market execution, process automation, and AI-powered systems. We don't just advise — we embed in your team and implement.
It starts with a 30-minute Fit Assessment with our Managing Partner (free, no obligation). If we're a fit, we propose a 3-month engagement with clear deliverables and KPIs. Most clients extend beyond the initial period. Our team works 2–3 days per week with yours, attends leadership meetings, and has direct access to founders/CEO. Think of us as a senior team embedded in your trenches — not advisors on the sideline.
Our clients typically see measurable revenue acceleration, margin expansion, and faster time-to-market within the first 90 days. We find the money that's already in your business and build the systems to capture it — systems your team owns and operates independently. Whether that means restructuring pricing, deploying AI automation, launching new revenue channels, or redesigning go-to-market — we build it, hand you the keys, and the problem stays solved. Our managing partners co-founded and scaled InstaCarro from zero to $105M in 2.5 years, delivering a 20x return to investors. Across 40+ engagements in 12 countries, we've impacted over $2.1B in client revenue. Due to confidentiality agreements, we cannot disclose specific client names — but we're happy to discuss anonymized case studies during your Fit Assessment.
Our engagements are designed to deliver 5–10x the total fee in measurable results. Unlike traditional firms that bill by the hour regardless of outcomes, Greyfeld Partners combines a retainer with a performance-based component — a significant portion of our compensation is tied to the outcomes we deliver. This ensures our incentives are fully aligned with yours: we build for growth that compounds, not headlines. Let's discuss specifics during your Fit Assessment.
Because diluting attention dilutes results. We could easily double our client base, but that would mean assigning junior teams to do the work while partners oversee from a distance — exactly what large firms do. We chose a different model: fewer clients, senior-led execution, and deeper impact per engagement. Our economics support this because our fees are tied to outcomes, not billable hours. When we go deeper, we deliver more, and everyone wins.
We take client confidentiality seriously. All our engagements are protected by non-disclosure agreements, and we do not share client names publicly. This is a deliberate choice — our clients trust us with sensitive strategic and financial information, and that trust is non-negotiable. We're happy to discuss anonymized case studies, share specific methodologies, and walk through our results framework during your Fit Assessment.
No. That's the point. Unlike traditional consulting firms that create dependency through recurring engagements, we build systems your team owns and operates independently. Every deliverable — whether it's a revenue engine, an AI automation pipeline, or a pricing model — is designed to run without us. We transfer knowledge, document everything, and train your team. If you want us back, it's because you have a new challenge — not because the old one broke.
