For a 20 person startup, it seems normal that the CTO would review all hires. If you visualize it as a small classroom's worth of people, it's easy to guess that new hires are probably still impactful enough on the company as a whole to get attention from the execs. Maybe not every company does it at 20 employees, but I imagine many still do.
