YesGraph was a San Francisco startup (YC W13) that provided a referral and contact-recommendation API. Its HTTP API and SDKs let mobile and web apps upload a user's address book and receive a machine-learning ranked list of which contacts a user should invite, powering smarter invite and referral flows. Founded by Ivan Kirigin (ex-Dropbox, ex-Facebook), YesGraph worked with companies including Airbnb, Atlassian, Gusto and Hired. In 2017 the team and its social-graph technology joined Lyft to strengthen Lyft's in-house referral program, and the public YesGraph API was deactivated on August 31, 2017. This profile documents the historical developer surface; the API is retired and no longer accepting traffic.
YesGraph is profiled on the APIs.io network. Tagged areas include Company, Referrals, Recommendations, Contacts, and Social Graph.
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/yesgraph: open an issue to ask a question, or submit a pull request to add artifacts.
