L'histoire complète
I built Buttondown as a side project while working at Stripe. 5-10% month-over-month growth for years led to $392K/year.
Side Project First
I scratched my own itch. I wanted a better newsletter tool than Mailchimp for my personal newsletter.
Patience and Quality
No hockey-stick growth. Just consistent 5-10% MoM improvement. Patience pays off.
Word of Mouth
Writers told other writers. The minimalist design attracted people who wanted simplicity.
- Years to $15K MRR: ~4 years
- Current revenue: $392K/year
- MoM growth: 5-10% perpetually
