The issue is that the investment market seems to be partially built on selling the idea that you're doing something so new and different that you need all these fancy architectures and hundreds of developers. If you don't sell that idea, you're just another CRUD company so why should anyone invest?
Look at all of the really successful tech companies out there, they startrd with tools already available. I see this too often. Everyone has nice ideas and wanted to write something better because they don't like the interface or they had to hack around (look at you Jenkins). We are all guilty of that. But if you hire people and they begin to create new fancy architecture that doesn't pay off, trust me, that money went to waste. This is not even a math problem.
Again, find a company out there did not create their infratructure with common solutions and only begin to develop custom solution when they afford and they really needed it. Several years later.
