Using ChatGPT and Voice Notes for Ideas

Charles Tenot is the CEO of Lemlist, the $33M bootstrapped B2B SaaS company behind LinkedIn favorites like Lemwarm, Taplio, and TweetHunter.

In this episode, he walks us through the transition from COO to CEO, what it’s like to follow a founder like Guillaume Moubeche, and how Lemlist builds brand without performance marketing.

He also unpacks his personal LinkedIn writing system (including how he gets post ideas on his motorbike), why repurposing content is underrated, and why shipping features again was key to breaking their $15M ARR plateau.

This one’s packed with stories and tactics from internal growth challenges to building a content-first culture that attracts top hires and drives 10:1 LTV to CAC.

What we cover:

- Charles’ transition from COO to CEO

- The honest truth about why Lemlist stopped growing and how they broke through

- How they restarted product velocity after 12 months of “tech debt”

- The Lemlist brand playbook: what it actually means to build trust

- Why Charles doesn’t believe in performance marketing (and what works instead)

- How he writes LinkedIn posts in 10 minutes

- His system for idea capture (Slack voice notes + ChatGPT for hook ideation)

- Why clickbait kills audience quality

- Internal content pods, incentives, and how Lemlist encourages employee posting

- Why he killed their SEO blog and what they replaced it with

Perfect for:

- B2B founders stuck at a revenue plateau

- CEOs looking to activate their teams on LinkedIn

- Marketing and brand leaders scaling a bootstrapped company

- Anyone trying to build trust in a noisy category
