Sinclair Growth Co works with high-growth B2B tech companies to build partner ecosystems, launch new markets, and turn commercial complexity into scalable, compounding revenue.
What we do
Most growth problems aren't marketing problems. They're structural. The wrong partner mix. A GTM motion that was never built for scale. A new vertical that nobody owns end-to-end. An integration bottleneck that's quietly killing retention.
Sinclair Growth Co exists for exactly those situations. We come in as a senior growth operator — not an advisor who writes reports and leaves — and we own the problem until it's solved. That means sitting in your team standups, negotiating your partner contracts, building your sales playbooks, and leading the cross-functional effort to get things shipped.
We bring 10 years of hands-on experience scaling partner ecosystems and GTM programmes at high-growth SaaS companies. We've managed deals with Meta, Google, Apple, and Amazon. We've opened new global verticals from zero. We've led M&A integrations under pressure. All with full P&L accountability.
Based in Berlin. Working across EU, UK, and North America. Fluent in both the commercial and technical conversations your growth requires.
Projects
Every engagement starts with a specific problem. Here's how we've approached the ones that matter most to scaling tech companies.
A premium boutique fitness operator expanding into the Berlin market had a location, a brand concept, and a deadline — but no digital presence, no acquisition strategy, and no operational systems. We stepped in as embedded growth lead: negotiating commercial contracts, building brand identity from scratch, architecting a social-first acquisition engine, and designing the full operational playbook for opening-day readiness.
A mid-sized German insurance operator had strong products but was losing younger customers to digital-first competitors. Their digital touchpoints were fragmented, acquisition cost was rising, and nobody owned the problem. We ran a full commercial and digital audit, identified three critical conversion gaps, and delivered a phased transformation roadmap covering CRM integration, AI-assisted communications, and a rebuilt acquisition funnel.
A global B2B SaaS company identified an untapped vertical with significant enterprise potential — but had no GTM motion, no sales process, and no internal owner. We led a cross-functional team to design and execute the full go-to-market from first principles: market sizing, ICP definition, partnership strategy, sales scripts, KPIs, and onboarding. Within 12 months the vertical was generating multi-million pipeline.
A fast-scaling SaaS platform was losing partners during technical onboarding but nobody had mapped where or why. Support tickets were high and churn was misattributed. We mapped the full dependency chain, identified the root causes, and led a cross-functional fix — turning the solution into a replicable onboarding playbook deployed across 100+ integrations.
A B2B SaaS company had a thriving partner ecosystem but every new integration required heavy manual effort. The model that worked at 20 partners was a bottleneck at 100+. We led the procurement of an iPaaS platform, designed the self-serve App Marketplace architecture, and drove the internal alignment to get it shipped on schedule.
Following the acquisitions of Sweet IQ Analytics and Momentfeed Inc., a global platform needed to integrate two product stacks, partner portfolios, and client bases without disrupting live revenue. We led product and vendor due diligence, managed partner contract transitions, and coordinated across legal, finance, and product to land both integrations cleanly.
How we work
What clients say
Liz is the kind of operator who speaks fluent product in a room full of engineers and fluent revenue in a room full of sales people. That combination is genuinely rare, and it's what makes her indispensable in a scaling organisation.
She doesn't just manage partnerships — she builds the architecture that lets those partnerships scale. The playbooks she created are still running today. When she took on a problem, it stayed solved.
Sinclair Growth Co took a complex, ambiguous brief and turned it into a revenue-generating vertical. They own their outcomes in a way that most operators don't. If they say they'll do something, it gets done.

The founder
Sinclair Growth Co is built around one operating principle: growth problems need operators, not consultants. People who will sit in the room, own the P&L, lead the team, and be accountable for the outcome.
Liz Sinclair has spent 10 years doing exactly that — building and scaling partner ecosystems, leading GTM programmes, and managing corporate development at high-growth SaaS companies across Europe and North America.
At Uberall, she owned a €7.5M P&L, managed relationships with Meta, Google, Apple, and Amazon, opened a new global vertical from zero to multi-million pipeline, and led two M&A integrations simultaneously. She has negotiated seven-figure contracts, built sales playbooks from scratch, and led engineering-adjacent work to fix structural integration problems at scale.
She is currently based in Berlin, deepening her cloud and AI engineering knowledge at Masterschool, and selectively taking on engagements where the problem is real and the ambition is serious.
