Andrew Brown's Playbook for B2B Infrastructure Fundraising

Most founders dream of a Google acquisition. Andrew Brown did it—and then left to do it all over again, raising $119M for his second act, Check. But this isn't a story about a lucky exit. It's a playbook on how to build a career, not just a company.

His journey from a 'scrappy' consumer app to a deep B2B infrastructure player holds critical, non-obvious lessons for every founder. Forget the generic advice. Here’s how to leverage a big-tech 'tour of duty,' find an unsexy but massive problem, and raise capital strategically.

Lesson 1: Your First Startup Is a Stepping Stone, Not a Destination

Brown’s first company, Oyster, was a classic startup story: a consumer-facing app aiming to be the 'Netflix for books.' Backed by Founders Fund and Highland Capital, it had the buzz and the brand. It was the kind of idea that gets you on the Today Show—and it did.

But the 'all-you-can-read' model was brutally difficult to make work economically against powerful publishers. Google saw the talent and the tech, not the business model, and made an offer. The acquisition of Oyster was less a triumphant exit and more of an 'acqui-hire.' This is a critical distinction.

The Common Mistake: Founders often view an acquisition as the finish line. They optimize for the highest price, burn out, and leave after their lock-up expires with no plan.

The Strategic Approach: Brown treated his vesting period at Google not as a golden handcuff, but as a paid, two-year research project. He didn't rest on his laurels; he began methodically searching for the next thing. An acquisition isn't retirement. It's your next round of funding, your next talent pool, and your next learning opportunity, all in one.

Lesson 2: Find the Problem a New Platform Creates

After two years of research inside Google, Brown and his reunited 'Oyster crew' spotted a second-order effect of a major tech trend. It wasn't sexy, but it was huge.

The Trend: Small businesses were flocking to vertical SaaS platforms—software built for the unique needs of their industry (e.g., Toast for restaurants, Mindbody for wellness studios). · The New Problem: These platforms managed booking, inventory, and payments, but one critical, painful function remained stubbornly manual: payroll. Business owners were still drowning in spreadsheets, tax forms, and compliance headaches. · The Insight: Don't build another payroll company to compete with the giants. Instead, build the tool that lets all the other software platforms offer payroll themselves.

This is the core of Check’s strategy. It’s an infrastructure company, providing a Payroll API that lets any vertical SaaS company become its own payroll provider. The vision is to make payroll an invisible, embedded feature that 'just works.' It’s a classic 'picks and shovels' play in a gold rush.

Instead of trying to be the next Gusto, Check empowers hundreds of vertical SaaS companies to become their own Gusto.

How to Find Your 'Check' Idea

Map a platform shift: What new dominant platform (like vertical SaaS) is changing how a specific industry operates? · Identify the gaps: What messy, regulated, or complex workflow does that new platform not solve? These are often the biggest opportunities. Look for things involving compliance, taxes, or complex calculations. · Talk to the customers: Brown and his team knew scores of small business owners. They didn't guess about the payroll pain; they saw it firsthand. Your best ideas live in the operational complaints of your target users.

Lesson 3: Fundraise for the Business You're Actually Building

With Check, Brown approached fundraising with a completely different mindset. He states that the 'relationships and advice...are in many ways just as important, if not more so than the capital itself.' For a deep infrastructure company, this isn't a platitude; it's a survival strategy.

Check has raised $119M, starting with a $1M seed from Bedrock. But it's who you raise from and why that matters.

The Common Mistake: Founders take the first check that hits their valuation target. They end up with consumer VCs on a B2B infrastructure cap table who don't understand the business model and apply the wrong pressure.

An investor who doesn't understand your business is not a partner. They are a liability that consumes your time and pushes you in the wrong direction.

The Strategic Investor Checklist for Infrastructure Plays

For a business like Check—API-first, long sales cycles, B2B2C dynamics—your investors must have specific experience. Before you even pitch, you should be qualifying them with these questions:

Do they have API-first DNA? Have they invested in companies like Stripe, Plaid, or Twilio? Do they understand that your customers are developers and product managers, not just business owners? · Do they understand platform sales cycles? An infrastructure sale isn't a quick SaaS sign-up. It can take 6-12 months to land a major platform partner. Your investor must have the patience for this and not demand hockey-stick growth in the first six months. · Can they make a different kind of intro? You don't just need capital; you need your first five design partners. The right investor can connect you to the CTOs and Heads of Product at the exact vertical SaaS platforms you need to build with. · Do they share the long-term vision? Brown’s vision is for payroll to be an invisible utility. That takes a decade, not a 'grow-at-all-costs' 18-month cycle. Your investors must be aligned on the timescale of the opportunity.

Raising a $1M seed for a company like this isn't about a flashy MVP. It's about selling a deep, hard-earned insight and a team with the credibility to execute. Brown’s two years of research and the loyalty of his former team were likely more valuable than any pitch deck.

How to Apply This Playbook This Week

You don't need a Google acquisition to start thinking this way. Here are three actions you can take right now.

Define Your Investor Thesis. Don't just list dream firms. Write a single paragraph defining what your ideal investor understands.

Where have you worked before? What unique operational pain did you see up close? Brown's parents were employment lawyers—payroll was in his DNA. Your history, no matter how unrelated it seems, contains non-obvious insights. List them. · Start Your 'Two-Year' Research Project Now. Pick one industry you know well. Find three people who run a business in it and interview them for 30 minutes. Ask one question: 'What is the most painful, manual process you wish your existing software would just handle for you?' Don't sell. Just listen. The next great infrastructure idea is hiding in their answer.
