I quit my job in January this year with no business but the thought that I must start, I can't work jobs anymore.
I built and marketed a simple micro-saas for Shopify ecosystem together with my co-founder. He handles tech, I do design and marketing. We both do customer support. App was launched on April 24.
June was my first month of revenue and we hit ~$450 MRR which I'm very happy about. Expecting large churn figures though.
This is the app -- https://apps.shopify.com/whatsapp-chat-button
Here's a post I wrote a month back chronicling the journey thus far -- https://www.preetamnath.com/blog/shopify-micro-saas-growth
Currently I'm learning how to code (Frontend, React) so that I can contribute to the app development, as currently our biggest bottleneck is development speed of new features.
