If you're interested in building a web application with less pain and fewer mistakes, you're in the right place.

I spent years making plenty of mistakes and learning lessons the hard way. I eventually sold my web application, and now I'm sharing everything I learned so you can do it all way better.

Hi, I'm Garrett. In 2008, I quit my job to launch a Saas application as a sole founder. Starting & Sustaining is a book and podcast 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 ever 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!

The Backstory

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 low-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.

The Book and Resources

I released the first edition of Starting & Sustaining in 2013. That was before my medical issues, joining Wildbit, and before selling Sifter. The combination of those experiences and context from the new perspectives helped me see a handful of additional things that I could add to the original book and improve it. So at the end of 2016, I set out to make some small updates. Those updates grew and grew, and now the second edition goes far beyond the original edition in scope.

The Podcast

Once I started on the second edition of the book, I reached out to others in the industry to talk with them about their journeys. What originally began as a series of casual conversations to complement the book turned into a regular podcast where I talk to other founders about their trials and tribulations. It was on hold while I finished the book, but it's back now that the book is complete.

What have people been saying?

…the accompanying spreadsheet has to be seen to be believed. While it's an incredibly useful tool for planning and measuring your business, it's also the most beautifully designed spreadsheet I've ever seen. Wade Winningham Developer at Updrift

OK, I haven't even had a chance to crack open the book yet, and I'd already pay twice this price—just for the spreadsheet alone.
