Pienza

Pienza is a Seattle-based B2B software startup studio and early-stage venture fund founded in 2020 by Aaron Bird (founder of Bizible, later sold to Marketo). Pienza partners with entrepreneurs to ideate, fund, and build category-defining SaaS companies, and later operated a Pienza Ventures accelerator focused on helping Indian SaaS and AI startups scale into the U.S. market. It raised $5.1M from MHS Capital, Version One Ventures, and Vulcan Capital plus angel investors. Pienza is a company-building and investment firm rather than an API provider; enrichment found no public developer API, API documentation, or developer portal, and the primary pienza.com domain no longer serves an active site.

Pienza is profiled on the APIs.io network. Tagged areas include Company, Venture Capital, Startup Studio, Software-as-a-Service, and B2B.
