We started end of 2015, and then went to YCombinator (Where startup like Airbnb, drobox, etc was groomed) in the summer '16.
After YCombinator we raised enough cash to build an MVP, which we did and launched on summer 2017 and instantly getting a lot of tractions in the market.
We grew a lot since last year that we outgrown our current office, so we're moving to a bigger one (can fit 50-60 people) in September!
