A bit of an aside, but one of the most important things that I've learned over my career is that the business wants to make as much money as possible. This may seem similar to "wants to spend as little money as possible," but there's a big difference.

Your floor is limited because you can only drop your costs to zero, but there's no ceiling on how much revenue you can make.

Nah, they want to bring in as much money as possible, subtle difference. High complexity (tech debt) and high costs (paying for expensive managed services) in service to time-to-ship is actually great. If it turns out that the market they predicted doesn't pan out they find out faster and just shut it down chalk it up to r&d costs for the tax break, and if it's so successful it costs them an arm and a let it's "good problems to have."

Well maybe not what it wants, but probably (depending on culture) what it _rewards_.
