Pros
I created SiPearl with Philippe Notton, its CEO. We hold the most craziest indea in the semiconductor and microprocessor industry located in Europe: developing a high-end general purpose processor competing with Intel and AMD in the supercomputer segment.
Like in any startup, we have to do everyhing on our own. Our number one priority: raise funds. Our second number one priority: hire, hire, hire!
After a whole carreer in the HPC industry and in large corporationb, I have to admit that I should have created my own company much earlier. I like it very much. Every day is a new challenge, every day is a new adventure on its own.
Cons
risks! But, no risk, no fun.
