There is no formula for how to value a startup after one year. In our case, we had over $1MM in revenue and built some very cool technology that was new to our space. It all depends on the company, the team, and the situation.
Also, while the brand (CraftJack) was a year old, I had started some of the properties we used to generate leads 1-2 years prior to that so was able to build some revenue from there.
