Accelerator

Techstars

Techstars is a global pre-seed startup accelerator and investor founded in 2006 by David Cohen, Brad Feld, David Brown, and Jared Polis in Boulder, Colorado, and headquartered in New York City. Operating a worldwide network of mentorship-driven accelerator programs across cities including Boulder, Boston, Chicago, New York, London, and Tokyo, Techstars runs an intensive three-month program that provides each accepted company roughly $220,000 in capital — a $20,000 convertible equity agreement for a minimum 5% of common stock plus an optional $200,000 uncapped MFN post-money SAFE (Asia-Pacific programs at ~$100,000). The firm is largely sector-agnostic but is especially active in AI/ML, fintech, SaaS, developer tools, healthcare, climate, space and defense, and critical infrastructure, and operates on its signature "Give First" philosophy. Techstars has backed more than 10,000 founders, producing dozens of unicorns and notable companies including Twilio, SendGrid, DigitalOcean, Uber, Remitly, Chainalysis, ClassPass, DataRobot, and PillPack, with portfolio companies collectively raising tens of billions in follow-on capital.

Cohort brief

Auto-generated

The 822 portfolio companies with APIs in the catalog, backed by Techstars, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.

A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.

This roster declares 972 members; 966 resolve to a provider in the catalog and 822 carry a score (85%). The figures above describe the scored members only.
Coverage caveat. 785 of 822 scored members had under half their catalog-attributable points satisfied at all (catalog_earned / catalog_max < 0.5). They are INCLUDED in the mean above. A large share here means the cohort mean is partly a measurement of how far our enrichment reached, not only of how these providers publish.Generated from the catalog build of 2 November 2026, across 37080 providers, using the same computation served by the APIs.io cohort API. Briefs are published for rosters of 5 or more scored providers; below that a distribution is not meaningful.
