How Nathan Barry bootstrapped Kit from zero to $42M ARR in 10 years

Nathan Barry spent the first 18 months of ConvertKit stuck at $2K MRR. Most founders would have quit. Nathan doubled down—and turned it into a $42M ARR business with $4M in annual profit. In this conversation, we break down the decisions and tactics that transformed ConvertKit (now Kit) from a struggling side project into one of the most successful bootstrapped SaaS companies of the last decade. We cover: The conversation with Heaton Shaw that changed everything Why he went all in after 18 months of stalled growth The exact moves that took ConvertKit from $2K to $10K to $100K to $500K MRR Why niching down to “email marketing for professional bloggers” unlocked traction How direct sales and concierge migrations fueled the early hockey-stick growth Why he still offers white-glove migrations today, even at $62 ARPU How webinars became his secret weapon between one-to-one demos and static websites The “minimum viable brand” playbook every founder should build Why you need to commit at least 3 years to any SaaS product before you can evaluate success How to focus on an audience (the right 10–100 people) instead of chasing a crowd The flywheel lesson: keep doubling down on what works Nathan’s story shows that you don’t need outside funding or a massive team to build big. You need focus, grit, and a willingness to do what doesn’t scale. Listen now to get the playbook. Subscribe to the Podcast If you found this episode valuable, please subscribe. Hit the bell.
