Buildspace

Buildspace was an online education platform and community that billed itself as "the biggest school in the world for people who wanted to work on their own ideas," running six-week cohort-based programs to help entrepreneurs and builders ship their own projects and startups. Backed by a16z, the company wound down its operations; its site now serves only a farewell letter and final video. It was a consumer education and community product, not an API provider, and exposes no public developer surface, API, documentation, or SDKs. This profile is retained in the API Evangelist network as a portfolio lead.

Buildspace is profiled on the APIs.io network. Tagged areas include Company, Education, Startup, Community, and Learning.

Regulatory Posture applies to this provider. Its tags matched the Education & Research regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
