Arianna Simpson is a General Partner at Andreessen Horowitz (a16z) crypto who joined the firm in 2019 — becoming its first female crypto GP — after founding Autonomous Partners, an early crypto hedge fund launched in 2017, and accumulating experience in tech and analytics at Facebook and Crystal Intelligence, with a portfolio focus at a16z that spans games, creator economy, DeFi, and consumer-facing crypto applications that bridges technical crypto primitives with mainstream adoption pathways.
Background
Arianna Simpson grew up in Switzerland and studied at UC Berkeley. She worked in the tech industry prior to crypto, including time at Facebook in product and analytics roles and at Crystal Intelligence — a blockchain analytics firm that provides transaction monitoring and compliance tooling to exchanges, financial institutions, and law enforcement agencies.
Her experience at Crystal Intelligence gave her direct exposure to on-chain data analysis, blockchain forensics, and the regulatory compliance challenges that crypto businesses face — a perspective that proved useful for evaluating both protocol-layer investments and consumer-facing applications.
Autonomous Partners
In 2017, Simpson founded Autonomous Partners — one of the earlier crypto-dedicated hedge funds targeted at institutional investors. The fund focused on investing in crypto networks and tokens with a thesis centered on long-term protocol value rather than short-term trading. Autonomous Partners gave Simpson direct experience managing a crypto portfolio through the 2017-2018 bull-and-bear cycle, distinguishing her credentials from investors who had only observed the space from traditional finance.
a16z Crypto
Simpson joined Andreessen Horowitz as a General Partner in the crypto team in 2019, making her the firm’s first female crypto GP at a time when gender diversity in crypto venture was extremely limited.
Investment Focus Areas
At a16z, Simpson has focused on:
- Games and metaverse — Evaluating blockchain gaming projects and virtual world platforms, applying a lens of mainstream consumer engagement alongside crypto ownership mechanics.
- Creator economy — Projects that use crypto primitives (NFTs, tokens, smart contracts) to enable creator monetization and ownership.
- DeFi — Decentralized finance protocols, with attention to sustainable token economics and user experience.
- Consumer crypto — Applications that bring non-native crypto users into on-chain ecosystems through intuitive products.
She has participated in investments across a16z’s Crypto Fund II ($515M, 2020), Fund III ($2.2B, 2021), and Fund IV ($4.5B, 2022).
Public Presence
Simpson has spoken at crypto conferences including ETHDenver, Consensus, and others, often on topics of consumer adoption, women in crypto investing, and the interface between Web2 products and Web3 infrastructure. She has also been vocal on structural issues in crypto markets and the need for clearer regulatory frameworks.
