Remember that their alternative is not “spin up VPSes” it is “staff an engineering rotation to maintain this service” which will cost them minimally a million annually. But the default alternative is "continue making limited use of these integration tests and continue accepting the delays of running them slowly" which has a cost of $0 compared to status quo. What proportion of series A companies that are trying to scale up and show results quickly so they are still around to raise a series B is going to spend $1M+ on a dedicated team to run a service for this? I'm guessing 0.000%. That means the comparison isn't a very compelling argument for the leaders in that organisation because really you're just arguing that your solution is better than something they obviously weren't going to do anyway.
