Refreshing to see. Usually employees are being treated as a resource to exploit. There is system called "market rates", where labour cost is actually fixed across the domains and is disconnected from the value workers generate. So you as an employee can develop something that saves company few millions, but still you'll get paid £65k and then dismissed the moment company doesn't need you.
They’re most likely doing it, and structuring it to vest in 2 years, to prevent “poaching” , leaks etc. which strikes me as a very temporary situation.
