Investor Profile: IndieBio - Thesis, Cheque Size & How to Apply

If you are a scientist founder wondering how to get funding from IndieBio, start with the science, not the pitch deck. IndieBio is SOSV's life sciences accelerator, built for teams turning biology into products that improve human and planetary health. It runs a four month programme from San Francisco and New York

Thesis and focus

IndieBio backs biology as a technology. Its thesis is that breakthroughs in therapeutics, diagnostics, food, agriculture, biomaterials and related fields stall not for lack of ideas, but for lack of early capital, lab access and company building help. It looks for a technical insight that can become a product, a credible path through regulation and manufacturing, and a market large enough to matter. Teams are typically pre-seed or seed stage, and many arrive straight from academic research.

The programme's home bases in San Francisco and New York matter for founders. IndieBio provides dedicated lab facilities so teams can run experiments without first raising enough to build their own lab.

Funding terms

IndieBio's standalone fund size is not publicly disclosed as a separate figure. What is publicly reported is the programme cheque: secondary coverage consistently describes an initial investment of $250,000, with additional milestone based funding reported to take the total to up to $525,000. Founders should confirm the current equity and instrument terms directly with IndieBio before applying, because accelerator terms can change between cohorts. At SOSV level, the HAX programme FAQ states that SOSV has over $1.6 billion in assets under management and is investing from SOSV Fund V alongside SOSV Select, its $100 million follow on fund.

Notable portfolio and partners

Well known IndieBio backed companies include NotCo, the plant based food company built around an AI formulation platform, and UPSIDE Foods, formerly Memphis Meats, which works on cultivated meat. Perfect Day, which uses precision fermentation to make animal free dairy proteins, is also widely cited as an IndieBio company. These examples show the breadth of the thesis, from food and agriculture to human health, rather than a narrow bet on one disease area.

IndieBio is a programme of SOSV, founded by Sean O Sullivan. It should not be confused with SOSV's hard tech programme, HAX, which is covered separately in this series. The two share a parent fund and a human and planetary health theme, but they serve different kinds of founders and run different facilities.

Programmes and support

The core offer is the four month accelerator itself: lab access, scientific and commercial mentorship, help with intellectual property, regulatory strategy and go to market planning, and introductions to follow on investors. IndieBio also evaluates companies on five questions, including what unfair technical advantage they hold, how the insight becomes a product, and how that product becomes a sustainable business.

How to apply for funding

Apply through the online application at indiebio.co/apply. IndieBio describes a process that begins with an online submission, followed by a technical due diligence video interview for selected companies, further calls on product, business plan and de-risking milestones, and then an offer if discussions are mutually favourable. Prepare proof of concept data, a clear statement of your technical insight, and a realistic plan for what the four months must prove.
