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. It was founded by Leshika Samarasinghe — early Google product team, founding member of ARPA-E, and former Managing Partner at The Production Board — who raised a $25M debut fund in 2022 (WSJ); Ethan Yeh, PhD, former Head of Data Science at Stripe, joined as Managing Partner. 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.

Twine Ventures is profiled on the APIs.io network. Tagged areas include Company, Venture Capital, Venture Firm, Investor, and Early Stage.

Regulatory Posture applies to this provider. Its tags matched the Health 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/.
