Here's a run-down of my story building, running, and ultimately selling Sifter from Peers Conference in 2017. Or you can read all about it below.

Hi, I'm Garrett. I've been working on the web since 1998. In 2008, I left my full-time job to freelance and bootstrap a hosted web application as a sole founder. In December of 2008, I launched Sifter, a bug and issue tracker. It eventually grew to a comfortable-six-figure revenue and provided a great living.

About five years into running Sifter, I had a minor surgery, and my recovery got a little sideways. I spent the next three years juggling surgeries (ten in all, including a below-knee amputation), physical therapy, doctor appointments, and Sifter. During that time, Sifter kept on trucking, and I began to recognize the value of SaaS and recurring revenue.

Despite my progress, in late 2015, exhausted from years of surgeries and recoveries, I decided to sell Sifter and move on. I simply didn't have enough left in the tank. I joined Wildbit, where I still work every day with SaaS applications like Postmark, Beanstalk, DeployBot, and Conveyor. The only difference is that now I'm surrounded by a large team.

Through this roller coaster, I've learned an incredible amount about SaaS. I look back at what I knew when I got started compared to what I've learned, and I wish every day that I could go back and share all of this knowledge with past Garrett. I can't do that, but I can write it all down and share it to help others.

I spent years making plenty of mistakes and learning lessons the hard way. Starting & Sustaining is everything I learned about building and operating a SaaS business.

Starting & Sustaining is a book, projections worksheet, playbook, and series of interviews with SaaS founders that pulls together all of my experience and that of the countless other founders I've talked to in order to help you build, launch, and sustain your SaaS business.

The book itself is entirely free on the web so anyone can learn and benefit. Each and every chapter from Starting & Sustaining is available on the site right now. The projections worksheet is availabe on Google Sheets for free as well. No strings attached.

Happy building!

What have people been saying?

There's no need to take my word for it. I've collected some of the comments from around the web so you can see what other founders of SaaS applications think about the book.
