Who can apply

Criteria stated by the funder on the official source.

Nationality

YC's application process is open to any startup, anywhere in the world. Tunisia is not named.

Stated

Startup stage

Any stage: about 40% of funded companies are just an idea, most have no revenue, and companies that have already raised money can apply. Incorporation is not required to apply.

Stated

Team

Solo founders are accepted, though YC advises having a co-founder; the founding team should be able to build the product itself, which usually means a technical co-founder.

Stated

Commitment

Founders must work full-time on the company during and after the batch, which takes place in person in San Francisco.

Stated

Company structure

YC invests in US, Canadian, Cayman and Singapore corporations; a company incorporated elsewhere must create a parent company in one of these jurisdictions.

Stated

Funding and what it does not cover

YC invests US$500,000 in each accepted company: US$125,000 on a post-money SAFE for 7% and US$375,000 on an uncapped MFN SAFE. This is an investment in exchange for equity, not a grant. Companies also get more than US$12M in partner credits and deals. YC charges no fees.
