Build the solution. Let us be the infrastructure.
Call it a wrapper if you like — the value was never the model. It is the domain judgment you wrap around it. Nobody buys your product because you wrote your own tenancy layer, so build the part your customers actually pay for and spend the rest of your time selling it.
Three things that kill a vertical AI product
The tenth customer
Isolation and per-customer metering were fine when there was one. At ten they are a rewrite — and it always lands the same quarter as your first real deal.
The security questionnaire
It arrives on your best opportunity. Access control, identity, screening, audit, retention — answered, or a month of scrambling.
Unknown cost per customer
You cannot price what you cannot cap. A ceiling per customer turns a guess into a gross margin.
Try a vertical for the cost of a few weeks.
If it does not land, try the next one. There is no team to unwind, no codebase to maintain and no infrastructure to switch off — so being wrong stays cheap, and you get more attempts for the same money. It takes attempts to find the one that works.
What you get
Multi-tenancy from day one — per-customer isolation, budgets and exact metering, already there.
It sits inside your product — the API and MCP surface mean your customers use your product, in your pages, on your domain.
One price covers the stack — the AI, the cloud and the storage in one number, not four variable bills.
What you build stays yours — your knowledge, your workflows, your customers. Everything is reachable over the API.
Your scarce resource is go-to-market, not engineering.
Every week spent on plumbing is a week not spent in front of a buyer.
