Buttondown
👤 Justin Duke (A Stripe engineer who runs his own newsletters — his own ideal user, out-crafting bloated teams solo for nine years.)🌐 sitejmduke.com𝕏
Justin wanted TinyLetter back after Mailchimp let it rot, so he built it himself on nights at Stripe.
Will it work? · our read
Durable on purpose. Modest revenue, but nine years of compounding trust, 61% growth, and zero investors mean Justin owns 100% of a profitable machine. The low ceiling is the whole point.

Buttondown 2025 year-in-review (Justin Duke): +61% revenue, +72% emails, cash-flow profitableLatka: Buttondown about $392K revenue (2024)Indie Bites: '$15k MRR side project while at Stripe' — Justin DukeJustin Duke built Buttondown for himself (TinyLetter origin)'Building a business by building less': the story of Buttondown
Revenue: the absolute figure (about $392K, 2024) is from Latka, a third-party database — tagged Stated, not independently confirmed, not an official company statement. What IS first-party (Justin Duke's own 2025 year-in-review) is the +61% revenue growth, +72% subscribers emailed, and 'cash-flow profitable, no fundraising.' No fabricated drama: Buttondown won on patient craft and TinyLetter's decay, not a dramatic single move. The 0%-cut pricing, TinyLetter origin, and Stripe backstory are documented facts; the 'do less as moat' framing is our read [infer]. We never score you.
