Techstars runs three-month accelerators, some based in startup cities and others in specialist verticals such as health, finance, space and defence, and critical infrastructure. Each gives early-stage companies investment, hands-on mentorship and access to the Techstars network of investors, mentors, corporate partners and alumni.

Formats vary by location. The New York City programme is hybrid: founders can be based anywhere and meet in person at the start, the midpoint and demo day. Techstars Anywhere runs remotely for companies in North American time zones, with three in-person offsites in venture hubs. Techstars Tokyo is backed by Mitsui Fudosan and JETRO Startup.

Programming covers pitching, fundraising, working with mentors, product-market fit, hiring, building and marketing, adjusted to what each company needs. In New York City, mentors are chosen after the class is final, and founders attend only the workshops that are relevant to them.
