Max founded Lumin to create a better way for people to annotate and collaborate on PDF files. He bootstrapped it to 30M users based on ad revenue, then made a very rapid switch to being subscription funded – in just 2 months! Lumin now has 80M users and 80 staff around the world and many documents are being signed every second. Max’s vision is to solve the pain of digitally managing, signing and sharing documents.
