I'm about to pull a "dropbox" here, but I am aware of many companies that already do this inside their Git infrastructure. It's not that hard to do when you combine verilator, testbenches in software languages, and cloud CI intended for software. This is one of the big advantages of greenfield designs (and FPGA companies): you can set things up for Verilator and/or CocoTB natively, and then you get to use things like Github actions to do continuous verification.
If you can get the commercial simulators and full support for the awful, ass-backwards, industry-standard verification frameworks (eg UVM), there's a great business here, but the trouble is going to be in getting there.
