  • "Kyle is extremely knowledgeable and I've learned a ton from him in this course, especially important architectural decisions, like what an API endpoint should look like versus a controller or model—and how they tie together. The beginning of the course is a bit slow, but it picks up from the 3rd module. Overall, the value that I gained learning strongly outweighed the cost of the course, and in general I enjoy Kyle's business practices and feedback style. Recommended to anyone looking to become a well-balanced JS developer."

  • "I saved months of time with Gravity and was able to focus on my main features instead of writing tests, setting up Stripe, Mailgun and figuring out authentication. The Slack support has been invaluable. Not only is Kyle extremely responsive, but other members of the community have even helped me late at night! Building a SaaS as a solo founder can be lonely so knowing you have the support of Gravity is huge. I was able to build my app in 8 weeks instead of months and months."

  • "Everything worked perfectly. I was pleasantly surprised by how user-friendly the whole setup process was – loved the unexpected setup wizard. I also appreciate the clean code and comments; as a Rails developer transitioning to Node.js that’s really helpful. Great SaaS boilerplate, exactly what I needed and it over-delivered at that price-point."

Kyle Gawley

I have been building SaaS products for a living for over a decade. My current venture is aSaaS boilerplate, which has helped 400+ founders to launch their own software products.

Previously, I launched 10 SaaS products; most failed but one reached $5m of sales. I was a lecturer at Ulster University in Belfast, teaching software development and UI/UX design.

I've been programming for twenty years (since I was 10!) and work remotely from locations all around the world, but you can usually find me sipping a mango smoothie in Thailand.
