Lusha is a 📝Business-to-Business (B2B) contact-data and sales-intelligence company founded in 2016 by Assaf Eisenstein and Yoni Tserruya. It sells verified business emails, direct-dial phone numbers, and company firmographics to sales, marketing, and recruiting teams through a web workspace, a 📝LinkedIn browser extension, a 📝REST API, and a remote 📝Model Context Protocol (MCP) server, and it claims roughly 290 million contacts and 29 million company profiles used by more than 280,000 teams.
Lusha began as a Chrome extension that revealed contact details on LinkedIn profiles and grew by self-serve adoption before taking institutional money: a $40 million Series A in February 2021 and a $205 million Series B in November 2021, both led by PSG, at a valuation of about $1.5 billion. It competes with 📝ZoomInfo and 📝Apollo on data coverage and with a credit-based pricing model that starts at a free tier, and it appears as an enrichment provider inside 📝Clay and 📝Cargo waterfalls. The company holds ISO 27001, ISO 27701, and SOC 2 Type II certifications, sources data from licensed directories, public profiles, and a user community rather than purchased broker lists, and has faced 📝General Data Protection Regulation (GDPR) inquiries in France and Italy. In 2025 it acquired the conversation-intelligence startup Novacy, added buying-signal and intent features, and shipped connectors for 📝Claude, 📝ChatGPT, and other assistants.
Lusha is the discovery-search provider in the 📝BrianBot outbound loop: 📝Hermes Agent runs filtered prospect searches against its MCP on a free tier of 40 credits a month, and Cargo carries the email resolution so the scarce Lusha credits stay on search. The operating detail lives in the Lusha Agent Operations Context.
