Thanks for sharing Nathan, glad to see things are working out so well for Convertkit! And very glad to see a bootstrapping story in such detail.<p>Nathan's book Authority led to my creating a website from my books in 2013, and it's grown handily. I currently have the opposite issue: my revenue growth slowed, but expenses are low so I have a largish runway. Recently started investing more in capital and look to be on a path to grow revenue with a new product very shortly.<p>Specifically a Macbook pro. I had been trying to launch an initial video product using a macbook air, figuring I'd buy the better computer once I had proven revenue. But that delayed me for months due to technical slowdowns. I bought the pro last week and will probably have a very minimal product out this week.<p>Slack's been a big help. Several years into the business my processes had gotten too complex and it was slowing progress.
