This only makes sense if you have a significant equity stake in the company you're working for. For the vast majority of engineers, they really don't care about the long-term profitability/success of whatever company they're working for. They just want to get paid, and hopefully grow as a dev in the process. They'll learn more by building something in-house than by bringing in a saas and just writing glue for a living. If you want your engineers to make the decisions a founder would make, give them a significant equity stake.
