There's a crazy story in here where Sytse invested in a click chemistry cancer research startup (Shasqi) in 2017 and ends up becoming a customer six years later.
I sincerely hope it works out for him.
It's mentioned in the slide deck on the url linked. I highly recommend clicking through all the slides. It's absolutely one of the most fascinating decks I've come across. His sheer will to want live is impressive and inspiring.
Also helps we were all batchmates in W15, so the serendipity is even higher.
