Twine Ventures

Twine Ventures is an early-stage venture capital firm "transforming human and planetary health," writing first checks into interdisciplinary, data-obsessed founders who use data and AI to transform legacy industries across healthcare, industrials, and fintech/data.

Its ~33-company portfolio includes Apella, Alaffia, Rupa Health (acq), Waltz Health (acq), Waymark, Teiko Bio, CloudCruise, and Rowspace. Surfaced as a Foundry Group partner-fund lead in the API Evangelist network; the firm runs a Webflow marketing site and publishes no public API, developer portal, or machine-readable surface.
