Overview

Bytemine is an advanced cloud-based B2B data platform and developer API architecture designed to supercharge modern sales, revenue operations, and AI-native Go-To-Market (GTM) pipelines. Housing a pre-verified global database of over 135 million professional contacts, 80 million mobile configurations, and 10 million comprehensive company profiles, the platform provides deep firmographic and technographic intelligence. Moving away from static, recycled lead sheets, Bytemine features RESTful data APIs with sub-200ms latency, a dedicated Model Context Protocol (MCP) server for native AI assistant configurations, and a powerful browser extension. This suite allows outbound sales teams and automated AI agents to search contacts using natural language, score real-time lead warmth indicators, and pipe fully enriched customer context directly into CRM databases.

Founder story

Bytemine was founded to resolve the massive operational friction and decaying database quality that standard outbound prospecting teams face daily. Recognizing that traditional database pools charge heavy per-seat premiums for stale data recycled from historical logs, the founders engineered a high-velocity developer infrastructure. Their goal was to make verified contact signals and firmographic data accessible natively through APIs, allowing modern growth teams to plug intelligence directly into active CRM pipelines and autonomous AI pipelines.
