I left Google about 8 months ago to build a Shopify app. I was a sales engineer that kept selling a super complex product to large retailers, and I thought it would be cool to "productize a service" and democratize it for smaller retailers.

It's amazing taking a full product from 0 to 1 with a small team, we're bootstrapped but have some revenue coming in now from very satisfied customers. I don't know if we'll ever raise money or have an exit, but I wouldn't trade the experience for the world.
