Partner at First Round Capital
Check size: First Round's published firm-wide initial checks are typically $1M–$7M, averaging about $3.5M; it has participated in rounds from $100K to $20M. No personal range is published for Brett.
Brett studies how thousands of small choices compound into an exceptional company. He backs very early builders with contrarian insight and an outlier capability, then works at the decision level rather than prescribing the finished product. His disclosed investments—Clay, Stedi, and Persona—show an interest in foundational B2B workflows: flexible go-to-market tooling, healthcare eligibility and claims APIs, and identity verification.
Explain the contrarian insight, the urgent customer problem, and the founder's unique spike; then show how your product, market choice, and go-to-market decisions compound. Use your natural voice rather than copying another founder's pitch style. If B2B, be ready to articulate the 4Ps—persona, problem, promise, and product—plus evidence that customers will pay. First Round reviews cold outreach, while trusted referrals tend to get a faster response.
Learn-it-all founders, a non-obvious view of the world, deep customer obsession, an outlier founder ability, large markets, early customer pull, and teams whose many small product and company decisions reinforce one another. He is drawn to builders who can explain why a neglected problem matters and learn faster than the market.
The published criteria imply weak fit for later-stage rounds, shallow trend-following, a nice-to-have without urgent customer pull, a market that cannot support a venture-scale outcome, generic storytelling, and founders who expect an investor to prescribe the end state rather than helping sharpen decisions.
Evaluate a company as the accumulated effect of thousands of product, hiring, market, and operating choices; help the founder improve those choices without dictating the final picture.
For early B2B discovery, make the persona, problem, promise, and product explicit, then test each through dollar-driven customer conversations rather than confirmation-seeking interviews.
Shape the financing narrative around the founder's authentic strength: technical founders may lead with evidence and mechanics, while culture builders may lead with talent and organizational advantage.

Sales-led B2B product-market fit can be treated as a measurable progression from nascent to extreme, with explicit work on customer discovery, market, positioning, sales, and iteration.
Fundraisers should surface investor objections, frame the company's biggest story, and build a pitch around the founder's authentic strengths rather than imitating famous presenters.
