Abdo Mallah
Entrepreneur and investor, CEO at Sowlutions
We created our second company in the last three years; this newest venture wouldn’t have been possible without Startup app — end of the story. We are able to go from wireframe to finished product 3x faster. The last one was entirely finished on mobile: Startup export > Working copy > Textastic. It’s mind-blowing. Five stars aren’t enough for all you do.
