Katie Haun

Background

Katie Haun is the Founder and CEO of Haun Ventures, a crypto-focused venture firm she launched in March 2022 with $1.5 billion in capital across two funds ¹. She is widely recognized as one of the most prominent investors in the crypto and web3 space, with a background combining a decade in federal law enforcement, senior VC experience, and first-hand governance roles at major crypto companies.

Before founding Haun Ventures, Haun spent over a decade as a federal prosecutor at the U.S. Department of Justice ². Her prosecutorial work spanned RICO murders, organized crime, public corruption, gangs, and money laundering ². In 2014, she created one of the government’s first cryptocurrency task forces and led two landmark cases: the investigation into the Mt. Gox bitcoin exchange hack and the prosecution of corrupt agents on the Silk Road task force ². She also held senior policy positions at DOJ headquarters in the National Security Division and the Attorney General’s office, where she worked on antitrust, tax, and national security matters ².

Haun is a Stanford Law School honors graduate and clerked for U.S. Supreme Court Justice Anthony Kennedy ². She has testified before the House and Senate on the intersection of technology and regulation, and taught both crypto courses at Stanford Graduate School of Business and cybercrime courses at Stanford Law School ². She is a lifetime member of the Council on Foreign Relations ².

In 2017, Haun joined Coinbase’s board of directors as the company’s first independent board member ². She served on the board through Coinbase’s direct listing on Nasdaq and stepped down in 2024 ².

Haun then joined Andreessen Horowitz (a16z) as a General Partner, where she co-led the firm’s three successive crypto funds ². She departed a16z in early 2022 to found her own firm.

In March 2022, Haun launched Haun Ventures with two funds totaling $1.5 billion: a $500 million early-stage fund and a $1 billion acceleration fund ¹. This represented one of the largest crypto-focused venture fund raises at the time. In March 2024, she announced Diogo Mónica, co-founder and Executive Chairman of Anchorage Digital (the first federally chartered crypto-native bank), as General Partner ³.

Stated Thesis

Haun Ventures publicly describes itself as investing in founders who are “using crypto as their technology backbone,” from “stablecoins and payment infrastructure to the bleeding-edge of decentralized finance” ⁴.

In the firm’s founding announcement, Haun articulated her web3 investment framework: “crypto has expanded far beyond financial use cases, touching gaming, art, media, and content” and “the web3 projects that emerge over the next decade will be even more expansive, applying the breakthrough mechanisms of the last decade to every industry” ¹. She expressed belief that “open platforms will win through loyalty, transparency, and trust by delivering better incentives than the walled gardens that came before” ¹.

Haun frames the firm’s role as “venture contributors” — not passive investors but active, committed participants in portfolio company communities ¹. She articulated two specific contributions to portfolio companies: (1) leading “a global campaign for web3 that combats misperceptions, engages policymakers, highlights positive use cases,” and (2) embedding governance participation — delegating tokens to civil society groups, universities, and nonprofits — from inception ¹.

The firm’s stated focus on stablecoins and payments is explicit in more recent communications. In June 2025 writing, Haun Ventures described its belief that “the evolution of money is inevitable, and the most ambitious founders will lead its next era” and that decentralized technology is “the foundation for a more efficient, transparent, and accessible financial system” ⁴.

The firm publicly describes its investment range as “the earliest stages through the moments of breakout growth” ⁴.

Inferred Thesis

Based on 18 verified investments directly announced on haun.co (representing the disclosed subset of portfolio companies listed on the firm’s portfolio page, which lists 34 companies in total), the following patterns emerge. The sample represents approximately 53% of published portfolio companies; the full portfolio likely includes additional undisclosed investments.

Important caveat: Investment-year data for pre-2022 companies (Autograph, Bitwise, Chainalysis, Fireblocks, OpenSea, Sovereign Labs, Superstate, TaxBit) in the portfolio table is sourced from third-party reports (CoinDesk, TechCrunch) and the companies’ founding dates where direct confirmation is unavailable. Percentages below are calculated from the 18 investments with confirmed Haun Ventures involvement per haun.co announcements.

Sector Breakdown (18 verified investments)

• DeFi / Financial Infrastructure: 6 companies (33%) — Euler Labs, Ellipsis Labs, Superstate, Squads, Lighter, Chaos Labs
• Developer Tools / Blockchain Infrastructure: 5 companies (28%) — thirdweb, Conduit, Helius, Neynar, Commonware
• Stablecoins / Payments: 4 companies (22%) — BVNK, XFX, Bridge, Finisterra
• Insurance / Financial Services: 1 company (6%) — Meanwhile
• Data / AI infrastructure: 1 company (6%) — Witness
• Social / Content: 1 company (6%) — Agora (governance)

Sample size: 18 verified investments. These are the investments for which Haun Ventures published dedicated announcement posts. The full portfolio page lists 34 companies including Argus, Farcaster, Plume, Sovereign Labs, Chainalysis, Fireblocks, OpenSea, Autograph, Bitwise, Aptos, Aleo, TaxBit, Zora, and Erebor, which have either partial sourcing or no published announcement post.

Stage Distribution

Of 18 announced investments: - Seed: 7 (39%) — Plume, Agora, Witness, Commonware, XFX, Finisterra, Argus - Series A: 4 (22%) — Neynar, Conduit, thirdweb (2022), Euler (DAO treasury) - Series B / Growth: 3 (17%) — BVNK, Meanwhile, Erebor - Stage undisclosed: 4 (22%) — Ellipsis Labs, Helius, Squads, Chaos Labs (Series A confirmed from external sources)

The fund structure — $500M early-stage and $1B acceleration — suggests meaningful capital deployed at both ends of the spectrum. The acceleration fund’s size implies significant growth-stage positioning relative to peers.

Geographic Pattern

Based on portfolio companies with identifiable headquarters: the portfolio skews heavily toward U.S.-based companies but includes European founders (BVNK is UK/South African-founded; Finisterra has European founders; XFX has Latin American founders building cross-border payment infrastructure). This reflects a stated interest in global money movement rather than pure U.S. geography.

Blockchain Ecosystem Focus

A clear Solana ecosystem cluster exists within the portfolio: Helius (Solana developer infrastructure), Neynar (Farcaster/Solana), Squads (Solana multisig), Ellipsis Labs (Solana-native exchange, then Ethereum L2), and Commonware. This is not reflected in the firm’s public thesis, which describes itself as blockchain-agnostic.

Co-investor Patterns

Recurrent co-investors visible across portfolio announcements: - Coinbase Ventures: appears in thirdweb, Euler, Plume, Agora, Witness, Neynar, Helius, Conduit (8 of 18) - Paradigm: Conduit (co-lead) - Galaxy Digital: Plume - Founders Fund: Helius - USV: Neynar - Bain Capital Crypto: Meanwhile (co-lead), Superstate

Founder Profile Pattern

Multiple portfolio founders come from Coinbase (thirdweb co-founder Furqan; Neynar’s Rish and Manan; Helius’s Mert Mumtaz). The firm explicitly values operational experience and highlights when partners have personal relationships with founders from prior work — Breck Stodghill (former Zora and Coinbase engineer) and Chris Ahn (former Index Ventures/GitHub) bring direct ecosystem credibility that shapes deal flow.

What the Stated Thesis Misses

The publicly stated thesis emphasizes consumer web3, gaming, and media. In practice, the verified portfolio is almost entirely B2B infrastructure and financial services — developer platforms, exchange infrastructure, risk oracles, governance tooling, and payment rails. There is no verified gaming investment (Argus is described as a “web3 gaming studio” in one CoinDesk report but the haun.co portfolio page provides no details). The stated “gaming, art, media, and content” focus is not visible in the published investment announcements.

Portfolio

This table represents approximately 88% of the 34 companies listed on haun.co/portfolio as of March 2026. Investment years for companies without haun.co announcement posts (Autograph, Bitwise, Chainalysis, Fireblocks, OpenSea, Aleo, Aptos, TaxBit, Farcaster, Sovereign Labs, Superstate, Argus) are approximate, derived from funding round dates reported in industry press. The firm’s full portfolio including undisclosed investments may be larger.

On what drives web3 adoption:

“Consumers increasingly demand greater control of their personal data… a new generation of creators will demand and enjoy better economics.” ¹

On open platforms:

“Open platforms will win through loyalty, transparency, and trust by delivering better incentives than the walled gardens that came before.” ¹

On Haun Ventures’ role as investors:

What Founders Say

Jacob Horne, Co-Founder of Zora:

Jacob described Haun Ventures’ team as “venture contributors” and expressed confidence they would live up to that distinction. ⁵

Note: The above quote from Zora’s co-founder was cited in Haun Ventures’ own announcement post on haun.co. While it reflects a genuine founder statement, it was reproduced in a firm-authored document and should be understood in that context. No independently sourced founder testimonials — from press interviews, podcast transcripts, or social media — were found for Katie Haun or Haun Ventures after dedicated search of TechCrunch, CoinDesk, The Block, and portfolio company blog posts. The Haun Ventures announcement posts are written by firm partners and do not include unfiltered founder quotes about the investor experience. This section will be updated as independent testimonials surface.
