How Guillaume acquired customers
Tools used to build Lemlist
Guillaume and two technical co-founders built Lemlist, reaching $250K ARR in one year with $0 in funding through Product Hunt and AppSumo.
365 days after launching Lemlist, Guillaume reached the quarter million ARR milestone. As a fully bootstrapped startup, reaching profitability quickly was their main focus.
As Reid Hoffman said: "If you're not embarrassed by the first version of your product, you've launched too late." Guillaume launched on Product Hunt first - they ended up #1 product of the day.
They made $160K in two weeks on AppSumo. But AppSumo took 70%, leaving $50K. Still worth it - thousands of companies were now using Lemlist, providing invaluable feedback.
They created "The Email Outreach Family" on Facebook. The goal: communicate directly with users, be real without BS, and talk to them like friends.
"Focusing on profit in a world where we associate startup success with money raised is definitely different, yet it gives perspective to anyone growing without funds."
