Bass Associates

Bass Associates is an early- and growth-stage venture capital firm historically based at 435 Tasso Street, Palo Alto, California, and appears on the Battery Ventures "list of all companies" as an exited entry. Public investor databases record roughly 32 investments and 10 exits alongside co-investors such as Accel Partners, Kleiner Perkins and CRV, with its last recorded investment (Teloquent, growth equity) in January 2002 and its last recorded exit in December 2003. The 2026 enrichment pass found no operating website, no developer portal, no documentation and no API surface of any kind: the firm appears dormant and is not an API provider. It was surfaced into the API Evangelist network by the VC-portfolio crawl as a Battery Ventures portfolio lead, but the underlying entity is itself an investor rather than an operating software company.

Bass Associates is profiled on the APIs.io network. Tagged areas include Company, Venture Capital, Investment, Finance, and Dormant.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bass-associates: open an issue to ask a question, or submit a pull request to add artifacts.
