Frequently Asked Questions about Polychain Capital

What is Polychain's check size range?
Polychain writes checks from $1M to $100M+, investing across seed through growth stages. The fund operates multiple fund vehicles, maintaining the flexibility to lead large rounds in the most technically ambitious projects — as evidenced by its co-leadership of the $110M Berachain round in 2025.
Who founded Polychain Capital and what is its track record?
Polychain was founded in 2016 by Olaf Carlson-Wee, a Coinbase veteran who was the exchange's first employee. As one of the oldest dedicated crypto venture funds with billions in AUM across multiple funds, Polychain has been involved in some of the most consequential early-stage bets in the ecosystem — including Filecoin, Cosmos, Compound, and Berachain — giving it institutional credibility and longevity that newer funds cannot match.
What types of projects does Polychain most want to back?
Polychain has the deepest conviction in novel L1 and L2 architectures, cryptographic research, and DeFi infrastructure — particularly teams pushing genuinely new approaches to consensus mechanisms, cryptographic primitives, or token network economics. The fund's portfolio reflects a preference for technically ambitious, architecturally novel work over incremental improvement on existing models.
Does Polychain require a warm introduction?
Polychain strongly favours founders with deep technical theses and novel approaches to consensus or cryptography — and warm introductions via the ecosystem are the preferred route. The most effective path is building genuine relationships through conference attendance, ecosystem collaboration, or publishing technical research that Polychain's team is likely to follow given their focus areas.
What stages does Polychain invest at?
Polychain invests from seed through growth. The fund is known for making early bets on novel chains and protocols before mainstream validation — its pre-launch investments in Filecoin and Cosmos are examples of backing architecturally ambitious work well before market validation. This early conviction on technical novelty is a defining characteristic of the fund's approach.
What is Polychain's most notable recent investment?
Polychain co-led the $110M Berachain fundraise in 2025, reinforcing its position as the go-to early backer for technically ambitious new chain projects. Berachain's novel Proof of Liquidity consensus mechanism exemplifies the kind of architecturally innovative work Polychain is drawn to — projects that propose genuinely new solutions rather than iterating on existing designs.
