Tau Ventures launches fourth fund, lifting seed cheques to $1M
What's the deal? Tau VenturesDealroom has a profile for this one. Try Dealroom →, a Silicon Valley venture capital firm co-founded by Brazilian-born Amit Garg, has launched its fourth fund. It targets startups in health, enterprise, and physical AI — autonomous cars, drones, and robots.
What's the endgame? The new fund keeps the firm's early-stage focus but raises its cheque size to a range of $500,000 to $1 million per company. That is up from $250,000 in Fund I and $500,000 in Fund II.
The backstory: Garg, the son of Indian parents, founded Tau Ventures with partner Sanjay Rao. The firm announced its first fund in 2019 and Fund II in 2022, both seed-focused; in 2020 it launched an Opportunity Fund to back portfolio companies in later Series A and B rounds.
Where it invests: Tau concentrates on the US for now, though it accepts startups with globally distributed teams as long as the chief executive officer is based where investors can offer stronger support. In Fund I, half its portfolio companies sit in the San Francisco Bay Area, with the rest spread across Boston, New York, southern California, and Austin.
The firm says it remains open to other markets, acknowledging that innovation can emerge anywhere. Its portfolio now spans 80 companies.
The Brazil link: Tau backs local startups including NiloDealroom has a profile for this one. Try Dealroom →, which closed a $70 million Series A in 2025, and Sami, which raised R$60 million in a 2024 Series B extension. It was also an investor in Salú, acquired by Senior SistemasDealroom has a profile for this one. Try Dealroom → for R$318.7 million.
The signal: Larger seed cheques reflect rising early-stage costs and competition in healthtech, enterprise software, and physical AI — the sectors clustered in the US hubs Tau targets. The move signals continued conviction in seed betting even as the firm scales its ambitions.
