Built for builders.

Built for the work in public

Founder Supply makes premium merch for YC-backed startups and the people building them. We focus on apparel and useful goods that show up at launch days, offsites, recruiting events, and everywhere a startup community gathers.

Startups build the future. We outfit it.

Merch should feel as considered as the company it represents. Founder Supply is built for teams that care about the details: a clear identity, sharp execution, and goods people genuinely want to keep.

From first hire to first hundred

From the first team uniform to customer thank-yous and community drops, we are here for the moments that turn an idea into a company.
