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.

Facet averages, against the whole catalog
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.
What this cohort publishes
mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.
This roster declares 972 members; 970
resolve to a provider in the catalog and 970 carry a score
(100%). The figures above describe the scored members only.Generated from the catalog build of
25 August 2026, across 26891
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.
