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.
