Let's do the math. He said 40+ worked on this tool. I'll round it to 50 people. Since it's a complex one I'll say the guys have been paid on average 10k / month. He also said they worked on it for 2 years, so that's 24 months. I'll ignore the other costs but we can safely double the total to cover it.
This means 240k x 50 which is $12M. So probably Invision probably spent around this amount up to date to build the tool. But most of the costs are pending - marketing, maintenance, feature parity with the other tools, bug fixing, etc.
Considering Sketch's maturity and adoption, I wouldn't be surprised if they offered 10 times more - probably 100-200M.
