Hayley Barna

Who they are

Hayley Barna is a Partner at First Round Capital — co-founded Birchbox in 2010, pioneering the subscription box model, before joining First Round in 2016 as their first female partner.

Person

Hayley joined First Round Capital in 2016 as its first female partner, leading the New York office at a firm that was already an established force in seed investing. Before that, she co-founded Birchbox in 2010 — right out of Harvard Business School — and built it into the company that essentially invented the modern subscription box. Earlier she was at Bain & Company as a strategy consultant, and also had stints at Christie's and Amazon. The Harvard double — undergrad at Harvard College, MBA from HBS in 2010 — anchors a career that moved from management consulting to consumer founder to venture partner without a gap year in between. The through-line is pattern recognition at category-creation moments: she helped invent subscription commerce, then moved to a front-row seat betting on founders doing the same in their own categories. On LinkedIn she writes about early-stage investing, founder psychology, PMF, AI in startups, and healthcare innovation — practical, operator-informed, not abstract. She also ran the Angel Track program for nearly 8 years with 400+ alumni, and recently hosted events for NYC operators thinking about making the founder leap.

Company

First Round Capital launched Fund X in 2026 targeting $500 million, with LPs including Princeton University and University of Michigan endowments — a signal of continued institutional confidence in the firm's seed-stage model. In 2026 the firm has been active in AI, backing companies including Clay (valued at $3.1B), fal (valued at $4.5B), and K2 Space (valued at $3B), alongside maternal health company Pomelo Care (valued at $1.7B). The firm's portfolio spans 53 companies with 44 unicorns and 4 decacorns, and its live positions carry an estimated equity value of about $2.4 billion across its 8 largest positions. First Round has also sharpened its investment criteria toward companies showing strong customer traction, unit economics, and clear paths to profitability. Beyond capital, the firm runs the Dorm Room Fund and Angel Track, and publishes First Round Review — a widely read platform of operational essays for founders.

Market

First Round Capital is one of the most active seed-stage technology investors in the US, operating in a market where early-stage firms compete on founder access, brand, and platform services as much as check size. Its named competitors include Eniac Ventures, NFX, Flybridge Capital Partners, and Chloe Capital, though the firm's historical portfolio — which includes Uber, Roblox, and Rover — gives it brand gravity most seed firms can't match. The broader venture market in 2026 is pushing seed investors toward selectivity and profitability signals, a dynamic First Round appears to be leaning into explicitly.

Network

Hayley's immediate professional circle at First Round includes founding partner Josh Kopelman and co-founder Howard Morgan, alongside partners Bill Trenchard, Brett Berson, Todd Jackson, and Liz Wessel — a team with operator roots across Google, Facebook, Twitter, Dropbox, and Stripe. Her Chief of Staff at First Round is Ashika Kalra. Beyond the firm, she sits on the executive committee of All Raise, the organization focused on accelerating female founders and funders, and is a board member at the Society for Science.

How they likely show up

Long tenure at First Round since 2016 (9+ years) → thinks in fund cycles and long arcs, not quarterly deal velocity.
Ran Angel Track for nearly 8 years with 400+ alumni → comfortable building structured, repeatable community programs, not just one-off events.
Co-founded and ran Birchbox as CEO from 2010 → brings genuine operator empathy to founder conversations; she's been on both sides of the table.
Active LinkedIn poster on PMF, founder psychology, and AI in startups → comfortable being a public voice and likely responds well to engagement with specific posts.
Hosted events for NYC operators transitioning to founders and shared posts on Spring Health–Alma and Thirty Madison acquisitions → tracks healthcare and mental health M&A closely; these aren't passive reposts.
Possibly — her science background (2001 Science Talent Search finalist) may make her more receptive to technical depth than the average consumer-focused investor.

Conversation tips

→ Reference something specific from her LinkedIn — she posts with a point of view on PMF and founder psychology, and she'll know immediately if you actually read it.
→ Ask about Birchbox as a founding experience, not as a company outcome — she went from operator to investor, and that transition is genuinely interesting to her.
→ She tracks healthcare M&A (Alma, Thirty Madison, Pomelo Care) actively — if you have a healthcare angle, surface it early.
→ Don't treat her VC role as her primary identity; she's a founder who became an investor, and that sequence matters to how she sees herself.
→ Angel Track ran 8 years and produced 400+ alumni — if you or anyone you know came through it, mention it; it's a real community she built.

Toolbox

Openers

Open on Angel Track winding down — she posted about closing the program after nearly 8 years and 400+ alumni, which is a natural moment to ask what she learned about what makes operators become good investors.
Reference the Fund X launch targeting $500M with university endowment LPs — it's the firm's most recent public move and a real conversation-starter about how First Round's thesis has evolved since she joined in 2016.
Lead with her 2026 healthcare bets — she's been publicly tracking Pomelo Care, the Spring Health–Alma deal, and Thirty Madison's acquisition; it's a clear sector conviction worth probing.

Discovery questions

You joined First Round in 2016 as its first female partner and led the New York office — how has the seed market's shift toward traction and unit economics changed how you evaluate companies at the earliest stage?
After running Birchbox from founding through the subscription-box wave, what do you look for in a founder that tells you they're building a new category rather than just a better version of something existing?
Angel Track ran for 8 years and 400+ alumni — now that it's wrapped, what was the hardest thing to teach operators who wanted to become angel investors?

Avoid

Don't pitch or discuss a company without having a specific hypothesis on why it fits First Round's current focus on customer traction and unit economics — she's sharpened her filter and vague 'big market' framing won't land.
