Bison Ventures Closes $160 Million Fund II for Physical AI

Bison Ventures has closed a $160 million second fund, according to an announcement reported by citybiz, and it will deploy the capital into startups building what the firm calls physical AI.

The close extends Bison's thesis that artificial intelligence's next wave won't live only in software. Physical AI describes systems that pair machine intelligence with hardware — robots, machines and devices that act in the physical world.

What do we know about Fund II?

The verified facts of the announcement are straightforward:

• Bison Ventures closed Fund II at $160 million.
• The fund will back physical AI startups, per the citybiz report.
• The firm has not, in the material available, disclosed limited partners, fee terms or a target check size.

The disclosed size marks a concrete step up in the firm's capacity. It also lands in a fundraising environment where investors have pulled back from hardware-adjacent risk, which makes a dedicated physical AI vehicle a contrarian signal rather than a bandwagon play.

Why does physical AI matter now?

The category has drawn growing attention as advances in foundation models make it cheaper to train systems that control machines. Investors have argued that robotics and autonomous hardware represent the next application layer for AI beyond chatbots and enterprise software.

Bison's fund gives that argument a $160 million balance behind it. The firm now has fresh dry powder at a moment when many deep-tech founders struggle to raise hardware capital, potentially giving Bison pick-of-deal access.

What happens next?

The firm will begin deploying Fund II into physical AI startups; citybiz's report did not specify the number of investments made to date or a deployment timeline. Expect the first announced deals from the vehicle to signal which slices of physical AI — robotics, autonomy, sensing or infrastructure — Bison intends to concentrate on.

This report is based on the announcement headline and summary published by citybiz. Additional deal terms, limited partners and portfolio details were not disclosed in the available material; we will update as the firm publishes full fund details.
