UserGems

UserGems is a San Francisco-based sales intelligence platform that tracks champion job changes and surfaces buying signals so sales and marketing teams can prioritize outbound and ABM motions. The platform packages 30+ native signals (job changes, contact-level intent, M&A, hiring, web visits), Gem-E AI agents for prospect list building and email personalization, and custom AI scoring trained on 600+ closed-won patterns. UserGems exposes a public REST API at api.usergems.com/v1 that lets customers programmatically add and remove contacts to track for job changes, add and remove target accounts, and honor data-subject deletion requests. The API uses an X-Api-Key header for authentication and processes submissions asynchronously. Native integrations include Salesforce, HubSpot, Microsoft Dynamics, Outreach, Salesloft, Gong Engage, Marketo, LinkedIn Ads, Meta Ads, and Google Ads.

UserGems publishes 3 APIs on the APIs.io network: Accounts API, Contacts API, and Privacy API. Tagged areas include Sales Intelligence, Outbound, ABM, Champion Tracking, and Job Changes.

The UserGems catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

UserGems’ developer surface includes authentication, developer portal, documentation, signup flow, pricing, engineering blog, support, and 24 more developer resources.
