Lenny Rachitsky launched the newsletter in August 2019. He hit 500K subscribers in 2023 and crossed 1M in early 2025. By any honest count it's the largest product newsletter, podcast, and community on Substack. The audience is product managers, founders, and growth operators at high-growth tech companies.The thing that separates Lenny's is research depth per post. He routinely spends 10 to 100 hours on a single essay, interviewing operators at Airbnb, Stripe, DoorDash, Notion, and dozens more. The podcast is its own thing now, with guests from across product, growth, and AI.The paid bundle is genuinely good. For about 150 a year you get the newsletter archive, Slack community access, plus subscriptions to Perplexity Pro, Notion Plus, Superhuman, Linear, and Granola. The included tools alone retail for more than the subscription.

What We Love

Watch Out For
- Mostly product and growth. Light on demand gen and SEO.
- Free tier gives you roughly 25% of the content
- High volume. Set a reading routine or you'll fall behind.
