Who knows what happend with Luc?

Surprisingly, Luc Hollande (former?) CEO of 4D SAS vanished

A reader pointed us to the company’s own web site and asked “Guess, who’s missing!” – It’s Luc Hollande, longtime CEO of 4D SAS, headquartered in Paris, France.
There is no hint in 4D blogs or news. Even Luc’s LinkedIn account still lists him as CEO of 4D.

So, if anyone can shed some light on this, I’m happy to listen.
