And Google just spent five times that to acquire a cyber security startup with 1000 customers. Is hardware so much less valuable?
Margins and TAM.
Those 1000+ customers at Wiz have 7-8 figure TCV deals (I have personally seen a couple of those contracts), and have pipeline in multiple industry verticals - Tech, Telecom, ONG, Healthcare, Finance, Insurance, etc
An embedded and telco oriented firm like Ampere has weaker margins as they have to manufacture hardware, which drastically reduces the amount of money available.
It's also a smaller and more consolidated market with a weaker TAM.
