OvaScience

OvaScience was a Waltham, Massachusetts biotechnology company founded in 2011 (by Michelle Dipp, Richard Aldrich, Christoph Westphal, Jonathan Tilly, and David Sinclair) that developed fertility and assisted-reproduction treatments for female infertility. Its two marquee IVF services were Augment (autologous mitochondrial transfer into a patient's egg) and OvaTure (maturing egg-precursor stem cells into eggs), launched in clinics in the UAE, Canada, and Japan starting in 2014. The company was surfaced as a portfolio company of Bessemer Venture Partners and added to the API Evangelist network as a stub for enrichment. OvaScience is defunct: in August 2018 it merged with Millendo Therapeutics via a reverse merger. It publishes no developer API, no OpenAPI, and no developer/documentation surface; its former domain (ovascience.com) now resolves to a parked lander.

OvaScience is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Biotechnology, Fertility, and Reproductive Health.

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/.
