Failed to Gain Traction, Goodbye to 4 years of work

So I started a SaaS 4 years ago. However, I can no longer keep up. I've issued refund to my customers. I'm closing shop. However, I don't feel sad, quite the contrary. I feel liberated and excited because I will be pivoting to a service only business. I feel that creating a tool which will handle all the billions of edge cases on my own is tough, especially with the small revenues. tl;dr: I'm ditching a software I created for the past 4 years, and I've just increased my prices about 10 fold, and have pivoted to a service business.
