Enterprises I have spoken to says they are getting pitched by 20 startups offering similar things on a weekly basis. They are confused on what to go with.
From my vantage point (and may be wrong), the problem is many startups ended up doing the easy things - things which could be done by an internal team too, and while it's a good starting point for many businesses, but hard to justify costs in the long term. At this point, two clear demarcations appear:
1/ You make an API call to OpenAI, Anthropic, Google, Together etc. where your contribution is the prompt/RAG support etc.
2/ You deploy a model on prem/private VPC where you make the same calls w RAG etc. (focused on data security and privacy)
First one is very cheap, and you end up competing with Open AI and hundred different startups offering it. Plus internal teams w confidence that they can do it themselves. Second one is interesting, but overhead costs are about $10,000 (for hosting) and any customer would expect more value than what a typical RAG provides. Difficult to provide that kind of value when you do not have a deep understanding and under pressure to generate revenue.
I don't fully believe infra startups are a tarpit idea. Just that, we havent explored the layers where we can truly find a valuable thing that is hard to build for internal teams.
