They're spending $30M+ on R&D, so if you feel that way as a customer, that's not good.
Additionally, PagerDuty works extremely well and I can't think of any additional features we need right now.
If you are talking instead about hiring an ops engineer to build your custom lightweight solution, I would ask why you're spending 100k+ all-in cost on an engineer to do something you could pay PD to do for cheaper.
I'm sure there are other options we could have tried, but it seems to do what we need pretty well.
