Haun Ventures

Kathryn Haun, as founder and CEO, leads all investment decisions with a small team of investors including Sam Rosenblum, who joined from a16z crypto. The firm does not publish a formal investment committee structure, but deal execution runs through Haun herself, consistent with debut fund dynamics where the GP's conviction drives portfolio construction.

While both firms invest in web3, Haun Ventures is not an a16z spinout — it was independently raised and operates with its own SEC registration. The firm's $1 billion acceleration fund is explicitly structured to purchase liquid tokens directly, a structure that sits outside the a16z platform's pooled fund constraints. Chris Dixon serves as a board partner but holds no operational role at Haun Ventures.

Both. The $500 million early-stage fund writes traditional equity and SAFE checks, while the $1 billion acceleration fund can acquire tokens directly — either via treasury purchases, secondary market acquisitions, or protocol-level commitments. This dual-structure approach allows the firm to participate in networks that may never issue equity.

The firm reserves meaningful capital for follow-ons, particularly through the larger acceleration vehicle. In practice, Haun Ventures has led or co-led Series B and later rounds in existing portfolio companies including Aptos and Fireblocks, signaling a high-conviction concentration model rather than broad index-style seed deployment.

The firm has not publicly published exclusion lists, but its portfolio is notably absent of mev-focused infrastructure, anonymous-founder DeFi protocols, and privacy coins — consistent with Kathryn Haun's law-enforcement background and public statements emphasizing compliance-forward web3 infrastructure.

Fireblocks provides institutional-grade crypto custody and settlement infrastructure — an enterprise-software layer that generates recurring SaaS revenue alongside transaction-based fees. Haun Ventures' participation in the May 2024 secondary round at $8 billion valuation reinforces the firm's thesis that crypto-native financial plumbing will converge with traditional capital-markets infrastructure.

As of mid-2026, Haun Ventures had not publicly disclosed a Fund II. The $1.5 billion raised in 2022 was sized with a long-deployment horizon, and the deliberate pace through 2023-2024 suggests the firm intends to exhaust its debut vehicles before returning to market.
