Hayley Barna

Who they are

Hayley Barna is a Partner at First Round Capital — co-founded Birchbox in 2010, pioneering the subscription box model, and ran Angel Track for nearly 8 years, graduating 400+ alumni.

Person

Hayley graduated from Harvard College with a Bachelor's in Economics (magna cum laude), then spent time at Bain & Company as a strategy consultant and had a stint at Christie's and Amazon before heading to Harvard Business School for her MBA. She co-founded Birchbox in 2010 — right out of HBS — building the subscription beauty box from scratch into one of the defining e-commerce brands of the early 2010s, serving as Co-CEO and Board Director through its run. In February 2016, she joined First Round Capital as the firm's first female venture partner, leading the New York office; she's since moved to full Partner. Alongside her investing work she ran Angel Track, a program she stewarded for nearly 8 years and 400+ alumni before winding it down. She sits on the board of Madison Reed and Collective Retreats, led First Round's investments in Thirty Madison and Mirror, and is on the executive committee of All Raise. On LinkedIn she posts regularly on pre-seed and seed fundraising, board meeting mechanics, investor relations, and AI in startups — practical, operator-flavored advice, not theory. The through-line is founder-to-investor: she built a consumer business, scaled it, then moved to the other side of the table without losing the operator's lens.

Company

First Round Capital is in active deployment mode in 2026, having launched Fund X targeting $500 million with university endowments — Princeton, University of Michigan, and TIFF Investment Management — as LPs. The firm's most recent bets skew heavily toward AI: seed and early-stage positions in Clay ($3.1B valuation), fal ($4.5B), Parallel ($740M, founded by former Twitter CEO Parag Agrawal), Together AI, Reducto, and Rillet, all backed between 2025 and 2026. Outside AI, the firm led the seed round for maternal health company Pomelo Care, which hit a $1.7B valuation in January 2026, and backed Persona's $200M Series D at a $2B valuation in April 2025. First Round writes checks of $750K to $4M at Seed and Series A, typically taking 15–20% ownership stakes; it also runs the Dorm Room Fund, the Graduate Fund, and the PMF Method program (launched 2024) as founder-support infrastructure beyond capital.

Market

First Round Capital operates at the seed end of venture — a crowded tier where it competes with Eniac Ventures, NFX, Flybridge Capital Partners, and Chloe Capital, among others. Its brand advantage is the First Round Review (a widely read operational essay platform for founders) and the depth of its portfolio network: 44 unicorns, 4 decacorns, 14 IPOs, and 213 acquisitions including Uber, Roblox, Notion, and Square. The broader seed market in 2025–2026 is seeing record AI funding and a push into fintech, climate tech, biotech, and defense, while geopolitical tensions and regulatory fragmentation are adding compliance complexity for cross-border deals — dynamics that reward firms with strong domestic networks and founder-trust at the earliest stages.

Network

Hayley's closest named collaborator is Katia Beauchamp, her Birchbox co-founder. At First Round, her partner group includes Josh Kopelman, Howard Morgan, Bill Trenchard, Brett Berson, Todd Jackson, and Liz Wessel. Her Chief of Staff at First Round is Ashika Kalra.

How they likely show up

Nearly 10 years at First Round after 6 years building Birchbox → thinks in long cycles; not looking for quick wins on either side of the table.
Ran Angel Track for nearly 8 years with 400+ alumni → patient community builder, comfortable with programs that compound slowly before showing results.
Active LinkedIn poster on fundraising mechanics and board meetings → prefers sharing operational specifics over big-picture takes; engages with concrete problems.
Hybrid role pattern (founder → operator → investor) → brings a dual lens; likely to stress-test founder claims against her own Birchbox experience.
Hosted an event specifically for NYC operators transitioning to founders → has a repeating interest in the operator-to-founder conversion, not just the startup-to-exit arc.
Possibly — science finalist background (2001 Science Talent Search) combined with an economics degree and HBS suggests she's comfortable with both quantitative rigor and market intuition.

Conversation tips

→ Come in with a specific operational question — she posts about board meetings, investor updates, and seed fundraising mechanics, so she's primed to go deep on the nuts and bolts.
→ Reference the Birchbox founding story if it's relevant, but don't make her retell it — she's been asked a thousand times; ask what she'd do differently now.
→ If you're a founder, be honest about where you are on PMF — she led First Round's PMF Method program and has seen every flavor of founder self-deception on this.
→ Mention a specific portfolio company or deal she's close to (Thirty Madison, Mirror, Pomelo Care, Madison Reed) — it signals you know her investing lens, not just her bio.
→ Don't treat her as primarily a 'consumer investor' — her 2025–2026 activity spans AI infrastructure, maternal health, and identity tech; she's not siloed.

Toolbox

Openers

Open on Angel Track closing after nearly 8 years and 400+ alumni — she posted about it herself, so she has feelings about what it built and why it ended; that's a rich conversation starter.
Reference Pomelo Care hitting a $1.7B valuation in January 2026 — she's betting on healthcare beyond her consumer roots, and the maternal health angle is specific enough to show you track her portfolio, not just her bio.
Bring up the PMF Method program First Round launched in 2024 — she's invested in the framework side of founder support, and asking how she thinks about diagnosing PMF versus growth-stage discipline will get a real answer.

Discovery questions

When you moved from running Birchbox to leading First Round's New York office in 2016, what was the hardest thing to unlearn as an operator when you started evaluating other founders?
First Round has seeded AI infrastructure companies (fal, Clay, Parallel) alongside maternal health (Pomelo Care) — how do you think about pattern-matching across categories that look nothing like each other at seed stage?
Angel Track ran for nearly 8 years and produced 400+ alumni — what made you wind it down, and what would a successor look like?

Avoid

Don't pitch her on a consumer subscription idea as if it's a novel model — she invented the category and will have strong views on what's structurally broken about the unit economics.
