The are in Europe and in France. The worst possible situation to be successful as a startup. I mean the extreme hiarchy, lack of salaries and taxation is not really gonna help.
And they obviously don't hire the right people. Reasons can be many-fold. One possible explanation is that there's not many talent left on the market, and most have been already picked up by other AI labs paying more $$$ while offering more exciting work and more exciting trajectory at the same time. Another possible explanation is that there is enough talent on the market left but their recruitment process doesn't allow them to recognize those people, hence it is broken. When I look into their job postings, I tend to give higher chances for the latter.
