Who we select

We back potential, not pedigree

Extraordinary founders aren't always born into extraordinary networks. Many have spent a decade or more mastering an industry and now see a problem no one else can. Others have built companies before or pursued an idea no one else believed in. We select pre-seed and seed founders who want to learn how capital really works before deciding whether and when to raise, with a focus on B2B, healthtech, deep tech and industrials, and we welcome exceptional founders in every sector.

Conviction

You understand a problem deeply and have a compelling reason to solve it.

Execution

You've moved past the idea and taken real steps to build, validate or launch.

Coachability

You welcome honest feedback and act on what you learn.

Generosity

You help the founders around you, because great communities are built by people who contribute.

A strong fit for the Pre-Accelerator

You bring 10+ years of experience in the industry you're building for
You have a product, prototype, pilot or paying customer
You want to understand your funding options before you decide to raise
You can commit about 6 hours a week for 10 weeks
You want candid feedback from investors

We look at what you know and what you've built, not degrees, past employers or existing connections.

Straight answers

Questions founders ask

What is Funding Breakthrough Lab (FBL)?

The FBL Pre-Accelerator is an equity-free pre-accelerator in San Francisco run by Funding Breakthrough Lab, a 501(c)(3) nonprofit. Each spring it selects up to 50 pre-seed and seed founders, called FBL Fellows, for a 10 week program with investors, operators and experienced founders. FBL has supported 72 founders across 3 cohorts.

Where is FBL based?

Funding Breakthrough Lab is based in San Francisco and works with founders, investors and operators across Silicon Valley and the San Francisco Bay Area. Most Pre-Accelerator sessions are live online, so Fellows can join from anywhere, with retreats and demo day in person in the Bay Area.

How is FBL different from other accelerators?

Most accelerators invest in your company in exchange for equity. FBL is a 501(c)(3) nonprofit pre-accelerator: it takes no equity and charges no tuition. It is built for pre-seed and seed founders who want to understand fundraising before they decide to raise, often before they apply to equity-based accelerators or approach investors, and it brings in 40+ investors, operators and founders every cohort.

Does FBL invest in its Fellows?

No. FBL is a nonprofit, so the pre-accelerator makes no investment and never takes equity. You keep 100% of your company.

Are the 50 seats for founders or companies?

The 50 seats are for individual founders, not companies. Each founder is selected on their own merits and joins the cohort as an FBL Fellow.

Do I need industry experience?

It's not required, but we especially look for founders with 10+ years of experience in the industry they're building for. Deep expertise is often what lets a founder see a problem others miss.

Can I apply with a job or while in school?

Yes, if you can commit about 6 hours a week for 10 weeks.

What if I'm not accepted?

You stay part of the FBL Community with access to open workshops and events, and you can apply again next cohort.
