Bytemine

Bytemine is a developer tool. Bytemine provides B2B contact and company data plus enrichment, verification, signals, and multichannel outreach through a web platform, REST APIs, MCP, and CLI. It targets GTM teams, AI agent builders, workflow automators, and SaaS platforms that need programmable business data without replacing their existing stack.

Bytemine is a programmable go-to-market and AI infrastructure platform built on a first-party B2B data engine. It combines a large contact and company dataset (135M+ contacts, 80M+ verified mobiles, 10M+ companies) with entity resolution, enrichment, verification, and multichannel outreach. Unlike point tools that only surface data in a web interface, Bytemine exposes the same records through REST APIs, an MCP server, a CLI, webhooks, and integrations, so teams, AI agents, and software products can work from a single source of truth. The platform is used in four main ways. Revenue and RevOps teams prospect, enrich, monitor target accounts, and run email plus LinkedIn sequences inside the Platform Suite while keeping their existing CRM. AI builders equip Claude, MCP-enabled ChatGPT, or custom agents with callable business-data tools. Workflow builders compose documented APIs and webhooks into their own automation runners. SaaS platforms embed contact and company intelligence into user-facing products through enterprise data APIs and licensing arrangements. In practice, a typical workflow starts with a search for contacts by title, seniority, company, or location. Records can then be enriched individually or in bulk (up to 100 contacts per API call), with email and phone verification available as separate calls. Credits are charged only on successful lookups: one credit returns one complete contact record. Outreach is included on every plan, including Free, and covers email and LinkedIn sequencing with one-click domain and inbox setup plus warmup. Bytemine sits between raw data providers and full sales engagement suites. It does not force a rip-and-replace of Clay, Apollo, or a CRM; many teams use it as the data and enrichment layer underneath their existing stack. Parts of the roadmap, including governed event-trigger orchestration v2 and Research, Discover, and Agents v2, are still in development. The public API contract and plain API-key authentication make the product straightforward to evaluate on a free account.
