AU21 Capital is a San Francisco-based venture fund that has invested in blockchain and Web3 projects since 2017. The firm focuses on early-stage deals – seed and Series A – across infrastructure, DeFi, NFTs, and gaming. With a portfolio of over 170 tracked projects and four unicorn outcomes, it stands among the more prolific early crypto VCs based in the United States.
The fund operates at the intersection of East and West, drawing on deep ties to the Asian crypto ecosystem while maintaining a US base. This network – spanning Chinese mining communities, Asian exchanges, and Silicon Valley developer circles – shaped the firm's deal flow in its formative years. Public AUM figures have not been disclosed.
Notable investments
- Binance – early-stage bet that became the world's largest exchange by volume, one of four unicorn exits in the portfolio
- Polygon (MATIC) – Layer 2 scaling network for Ethereum, now a core piece of EVM infrastructure
- CertiK – blockchain security auditing firm, reached unicorn status in 2022
- Helium – decentralized wireless network, acquired by Nova Labs; represented a notable exit
- Axie Infinity – play-to-earn gaming pioneer (Sky Mavis); peak valuation exceeded $3B before the Ronin bridge hack in 2022
- Injective Protocol – Layer 1 chain for decentralized finance applications
- Fantom – EVM-compatible Layer 1; rebranded as Sonic in 2024
- Casper Labs – enterprise-focused blockchain with proof-of-stake architecture
- Star Atlas – Solana-based space strategy game and metaverse project
- IoTeX – blockchain infrastructure for connected devices (DePIN sector)
The portfolio spans multiple market cycles. Some early bets – Binance, Polygon, CertiK – delivered exceptional returns. Others, including Axie Infinity and several DeFi tokens from the 2021 cycle, saw sharp drawdowns. The reported retail ROI of 0.07 on tracked projects reflects broad averaging across wins and losses in volatile market conditions.
Team
Chandler Guo co-founded AU21 Capital after running one of China's earliest large-scale Bitcoin and Ethereum mining operations. He is a well-known figure in the Chinese crypto community and an early participant in Ethereum's development ecosystem. His mining background gave the firm early access to layer-1 infrastructure projects.
Kenzi Wang served as Vice President and General Manager at Huobi Global, where he oversaw exchange operations, business development, marketing, venture activity, and token listings. His background in exchange operations shaped AU21's strong network in Asia-based projects. Public information on other investment team members is limited.
Recent activity
AU21 Capital's investment pace slowed significantly through 2024 and into 2025 – a pattern shared across the early crypto VC cohort following the 2022 bear market. Tracxn data as of early 2025 recorded one new investment in the prior 12 months: a $1 million seed round in Anmol, co-led with HG Ventures. No major fund announcements or new flagship investments have been publicly reported for 2025–2026.
The firm has not announced a new fund vintage. Whether it is actively deploying capital from an existing vehicle or in a quieter phase is not publicly confirmed.
AU21 Capital's strongest years were 2019–2021, when its Binance, Polygon, and CertiK positions appreciated sharply. The firm's geographic bridge between the US and Asian crypto markets remains its defining characteristic. For projects seeking both US institutional credibility and connections into Asian exchanges and communities, AU21 has historically offered a distinctive value proposition. Whether it returns to a higher deployment cadence in the current market cycle remains to be seen. Crunchbase profile here.
