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. That API is deliberately write-only — there are no read or GET endpoints — authenticates with a single company-wide X-Api-Key header, is capped at 20 requests per second with one record per request, and acknowledges enqueueing rather than completion. UserGems also ships a hosted remote MCP server at app.usergems.com/mcp/usergems, in gated early access as of August 2026, that lets agents in Claude or ChatGPT search accounts and prospects, pull signal and score history, run research, draft Gem-E messages, and build and run campaigns including CRM writes, sequence enrollment and ad-audience sync — authorized with OAuth 2.0, dynamic client registration, PKCE S256 and a single mcp:use scope. Native integrations include Salesforce, HubSpot, Microsoft Dynamics, Outreach, Salesloft, Gong Engage, Marketo, LinkedIn Ads, Meta Ads, and Google Ads.
