SigFig

SigFig is a San Francisco-based wealth management technology (fintech) company. It operates two lines: "Tandems," an enterprise platform that helps financial institutions deliver intelligent, personalized financial advice, and "SigFig Wealth Management," a consumer robo-advisory service that builds and manages tax-efficient, diversified investment portfolios tailored to each client's goals. SigFig is backed by Bain Capital Ventures, DCM Ventures, and Union Square Ventures. As of the 2026-07-21 enrichment pass, SigFig publishes no public developer API, SDK, MCP server, or developer portal; its site is served behind a WAF and the developer/docs/api subdomains do not resolve.

SigFig is profiled on the APIs.io network. Tagged areas include Company, Fintech, Wealth Management, Robo-Advisor, and Investing.

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/sigfig: open an issue to ask a question, or submit a pull request to add artifacts.
