Lemlistby Guillaume Mubesh
Lemlist is an email automation platform that uses advanced personalization (videos, dynamic images, personalized landing pages) to improve cold email reply rates. Guillaume Mubesh built a 'very ugly beta' in 2 weeks with 100 signups, then prepared for an AppSumo launch two months later where they generated $170,000 in two weeks. They've since grown to ~$650k ARR in under two years through Product Hunt (ranked #1 product of the day), community building, LinkedIn content, and their own cold email outreach using the product.
