11x
11x builds autonomous AI "digital workers" for revenue teams — Alice, an outbound AI SDR that prospects, researches, and runs multi-channel email and LinkedIn outreach against a 400M+ B2B contact database, and Julian, an inbound AI phone, chat, and SMS rep that qualifies leads and books meetings in real time. The company markets a single unified platform API across both workers for triggering outbound, inbound, and meeting booking from external systems, plus webhooks and native bi-directional Salesforce, HubSpot, and Zoho CRM sync brokered over OAuth via Ampersand. Founded in 2023 with offices in San Francisco and London, 11x has raised roughly $75M across Seed, Series A (Benchmark Capital) and Series B (Andreessen Horowitz), with participation from HubSpot Ventures, Abstract Ventures, and 20VC. The platform API reference and any machine-readable specification are not published publicly — api.11x.ai answers anonymous requests with HTTP 403 and the marketing API page routes to a sales demo rather than a developer reference.
11x publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, Sales, and Sales Automation.
11x’s developer surface includes documentation, engineering blog, support, signup flow, pricing, changelog, authentication, and 24 more developer resources.
