Benoit Masson - Biogen
We are looking for companies that have our DNA. BDH will not focus on the big market, but rather look at start-up type “markers”, short iterative cycles, lean mindset, agile methods.
BeTomorrow has demonstrated its ability to enrich the value chain upstream (UX/UI) and downstream. There was a lot of expertise present, it was interesting to see that and very reassuring.
