Sales Engagement Software

Lemlist is a sales engagement platform founded in 2018 that helps salespeople find leads, source contact information, and run multichannel outbound campaigns across email, LinkedIn, WhatsApp, and phone. The company is headquartered in France and operates under the Lempire parent brand, which also houses several smaller software products. As of late 2025, Lemlist has reached approximately 40 million euros in annual recurring revenue, with the broader Lempire portfolio adding roughly 4 million euros in ARR from other products, bringing the combined total to approximately 40 million dollars. The business has remained fully bootstrapped since founding, with no outside institutional funding raised, and operates at an EBITDA margin the company targets between 20 and 35 percent, generating approximately 10 million euros in annual profit. In October 2025, Lemlist announced the acquisition of Clap, a call intelligence platform, in a deal structured with a headline value of 25 million dollars. The transaction combines Lemlist's distribution capabilities with Clap's AI-powered call recording and transcript product, which had reached 2 million euros in ARR with a team of seven and was growing at roughly 10 percent month over month at the time of the deal.
