Guillaume Moubeche

Co-founder of lemlist, bootstrapped from $1K to tens of millions in ARR

About Guillaume Moubeche

Guillaume Moubeche is a Paris-based entrepreneur and the co-founder and CEO of lemlist and its parent company lempire. He launched lemlist in 2018 with two technical co-founders and only about $1,000, at first trading lemlist accounts for tools the team could not afford.

lemlist, a cold email and multichannel outreach platform, grew extremely fast through content, community and Guillaume's own personal brand, crossing $1M ARR in under two years. The company refused venture funding; in 2021 the founders instead took a secondary cash-out at a $150M valuation while keeping the business profitable and self-funded.

lempire has since expanded into a family of sales and social tools including lemwarm, lemcal, and the X and LinkedIn growth tools Tweet Hunter and Taplio, acquired from indie hacker Tibo Louis-Lucas. Reports in 2025 put the group at around $40M ARR, and it used its profits to acquire meeting tool Claap. Guillaume is one of the most visible advocates of bootstrapping in Europe and hosts the BILLIONS podcast.
