Investor Profile: Bee Partners — Thesis, Cheque Size & How to Apply

Bee Partners is a San Francisco pre-seed venture firm, and Bee Partners funding is deliberately aimed at the hardest moment in a company's life: before product, before revenue, and before the market sees what the founder sees. The firm's phrase for this is conviction at inception, and it has practised that approach for fifteen years. If you already have strong revenue and want a priced growth round, this is not your investor.

Investment thesis

The original thesis, set out when Michael Berolzheimer founded the firm in 2011, was that machines would reshape every industry. That bet is now consensus, but the method has not changed: back radical technical founders at inception, using the firm's Frontier Curve of Innovation framework to judge where a technology sits on its path to market. The firm looks for founders who are already living in the future, with unfair access to data and earned expertise.

Sectors and stages

Bee Partners invests at pre-seed only, in AI-native infrastructure, agent orchestration, next-generation manufacturing and frontier materials, with a longer history across AI, robotics, advanced manufacturing and synthetic biology. It backs founders creating futures where AI agents run enterprises, where hardware takes months rather than years, and where physical limits stop being the constraint.

Fund size and cheque size

The firm's current site states pre-seed cheques of $300,000 to $500,000, conviction-first. Total assets under management are not publicly disclosed on the pages read for this profile, so no fund-size figure is stated here. Context for the track record is strong: nearly 100 companies backed across four funds, with more than $2 billion in follow-on capital and about 60% of portfolio companies historically reaching Series A.

Notable portfolio

Category-defining exits in the portfolio include TubeMogul, which went public, BuildingConnected, acquired by Autodesk, tbh, acquired by Facebook, and TensorStax, acquired by Snowflake. Current companies highlighted by the firm include InnerPlant, DeepScribe and C-Infinity.

Partners and team

The firm was founded by Michael Berolzheimer, Founder and Managing Partner, who is described as a hands-on builder of proprietary AI and graph-based tools for portfolio intelligence. Venture partners include Tim Smith, Kira Noodleman, Alejandra Vergara and Austin Grisham, with Jocelyne Cooke as chief financial officer. The firm stresses that its venture partners do real work inside portfolio companies at critical moments.

Programmes, credits and perks

No accelerator, credits programme or perks bundle was found on the pages read for this profile. What Bee Partners offers instead is intensive partnership: strategic introductions to customers, future partners and employees, and capital sources, plus hands-on help when a company is under pressure. The firm's own test is blunt: when a founder has sixty days of cash left, or a lead investor walks away, they call Bee Partners, and the firm picks up.

How to apply for funding

Bee Partners does not run an open application form. Its Work With Us page is explicit: the best way to reach the firm is through its network, and it invests through conviction, not volume. Founders should therefore seek a warm introduction from a portfolio founder, a technical peer or a co-investor, and arrive with a clear account of the future they see that the market does not yet understand.
