Investor Profile: Factorial Funds — Thesis, Cheque Size & How to Apply

Factorial Funds is a Menlo Park, California venture firm founded in 2021 by Sol Bier, who previously helped grow Cruise Automation from a small autonomous-vehicle startup into a $1 billion acquisition by General Motors in 2016. The firm's own one-line thesis is unusually complete: "We invest in the companies defining the AI era: the intelligence, the silicon, the infrastructure, and the power to run it." In May 2025 it announced Fund II, a $200 million second institutional fund anchored by Hyundai Motor Company and Kia.

What Factorial Funds invests in

The specialty is the full AI value chain rather than a single layer of it. Fund II coverage describes the mandate as artificial intelligence, cloud and data infrastructure and robotics, across early and growth stages. Fund I's named positions show what that means in practice: Anthropic, Perplexity, xAI, Mistral AI, Ayar Labs, SpaceX and The Bot Company — frontier model labs, AI search, photonics for AI interconnects, space and robotics in a single portfolio.

Cheque size and deal pace

The firm does not publish a standard cheque size. Its website is deliberately minimal — essentially the thesis line and nothing else — and neither Fund I nor Fund II coverage states a per-deal range; the $200 million figure is the size of Fund II, not a cheque. The firm also publishes no annual deal count, so no defensible startups-per-year average exists. What can be stated is the basis: founded in 2021, two institutional funds in four years, and a Fund I portfolio that already includes at least seven category-defining names.

Notable exits

No exits are documented in the sources for this profile, and founders should read that correctly rather than as a red flag: a firm founded in 2021 whose best-known holdings — Anthropic, Perplexity, xAI, Mistral AI and SpaceX — are still private has simply not reached the exit stage of its fund lives yet. Its track record so far is mark-to-market quality of access, not realised returns.

How to apply for funding

Factorial Funds has no open application form, no accelerator and no published pitch portal; its website carries no application route at all. In practice this is a warm-introduction firm: the realistic path is an introduction through a founder, operator or co-investor in the AI ecosystem who can credibly place you in front of the partnership, with a technical thesis that maps onto the intelligence–silicon–infrastructure–power chain the firm invests behind.
