Investor Profile: Tau Ventures — Thesis, Cheque Size & How to Apply

Tau Ventures is a Palo Alto early stage venture firm founded in 2019 that backs applied artificial intelligence where it can change a real workflow, not where it merely demos well. For founders researching how to get funding from Tau Ventures, the central test is practical: can AI remove cost, delay or error from digital health, enterprise work or physical automation, and can the team sell that result to customers who already feel the pain?

Investment thesis

Tau Ventures invests at the seed stage in AI first companies, with follow on capacity into later rounds for its winners. Its thesis is deliberately narrow. It prefers applied AI over general research bets, and it looks for companies roughly ready to prove product market fit rather than ideas still searching for a problem.

Sectors and stages

The firm focuses on three areas: digital health, enterprise software and automation, including cars, drones and robots, often called physical AI. Within digital health it leans towards fast growing, largely unregulated workflows such as scheduling, calls and administrative automation, rather than only regulated clinical products. Within enterprise it covers areas including fintech infrastructure, cybersecurity and human resources technology.

Fund size and cheque size

Tau Ventures manages over $100 million across its funds, according to 2026 reporting, while earlier reporting put assets under management at over $93 million as of December 2025. Its Fund III, filed in July 2026, continues the seed strategy, but its target size was listed as indefinite in regulatory filings and is therefore not publicly disclosed as a headline target.

Notable portfolio

The portfolio includes Assort Health, whose AI handles patient scheduling and call centre work for medical practices and which reached a $1.2 billion valuation after a later funding round. It also includes Labelbox, a data platform used to build and manage AI training data; Chef Robotics, which builds robots that assemble meals for food companies; ArmorCode, focused on managing cybersecurity risk; Infinitus, whose AI voice agents automate healthcare phone calls; and Iterative Health and Cerby in health and enterprise automation.

Partners and team

The firm was founded by Amit Garg and Sanjay Rao, both formerly investors at Norwest Venture Partners. Garg specialises in digital health and previously worked at Samsung NEXT Ventures and Google, while Rao specialises in enterprise and automation and previously worked at Microsoft and McKinsey and as an investor at Norwest.

Programs and perks

Tau Ventures does not run a verified standalone accelerator programme with open cohorts. Its support is instead hands on and deal specific: customer and strategic introductions, market intelligence, investor mapping for the next round, go to market positioning and senior hiring help.

How to apply for funding

There is no verified public pitch portal for Tau Ventures, so founders should approach through the firm's website contact route or, preferably, through a warm introduction from a portfolio founder, co investor or operator in its network.
