How Guillaume Moubeche Built a $150M SaaS Empire from $1K

Introduction

Guillaume Moubeche launched lempire in 2018 with $1K. Four years later, he sold 20% of the company for $30 million. Today, lempire’s products, including lemlist, lemwarm, lemcal, Taplio, and Tweet Hunter, serve over 125,000 businesses worldwide.

In this conversation, we unpack how he built a hypergrowth SaaS company in a crowded market with zero outside funding, using a product-led approach, bold branding, and smart timing.

We cover:

• How he started with $1,000 and landed his first customer

• What moved the needle from $0 to $1M ARR in two years

• The strategy shift that took lempire from $1M to $10M ARR in 18 months

• The growth tactics he’d double down on—and what he’d cut

• Why he used lemlist to sell lemlist, and how founders with non-sales tools can apply the same logic

• The thinking behind his Sales = Trust × Timing formula

• How he launched multiple complementary products under the lempire umbrella

• Why he sold 20% of the company and what it unlocked

• How he balances scaling, writing, and training for Ironman competitions

Guillaume’s story is proof that you don’t need a massive team or millions in funding to build something big. You need leverage, focus, and conviction.
