We actually have 3 co-founders. Radek built aggie.io - it's been online for a few years. He initially built it to draw with his friends from South America. ;) First-hand need for art collaboration hehe.

Wojtek and I were in the meantime building code2flow.com, collaboration solution for diagrams. Also took us a few years.

2 years ago we decided to join forces and built an ultimate art collaboration solution with the experience and codebases from Aggie.io and code2flow.com.

Hard to say how many years ... Definitely over ten thousand of engineering hours but at the same time things were a bit harder few years ago when it comes to browser APIs so if we decided to rebuild it today it could take less time but we would also be more experienced.

Today we're hiring some more people and it's a team effort!
