AI for SaaS
Most SaaS teams do not need a new company. They need one workflow where AI is testable, plus UI checks so the product still looks like itself after each release.
The three requests we get from SaaS teams
"Our customers are asking for AI." This usually means one workflow inside your product would be faster with a model in it — drafting a reply, summarising an account, answering from your docs. It rarely means a chat box on the dashboard, which is the version that ships first and gets used least.
"Support volume is growing faster than the team." A retrieval assistant over product docs and resolved tickets is the well-understood build here, and the honest version shows its sources so an agent can check it in two seconds. See RAG development.
"We ship fast and keep breaking the UI." That is a quality problem, not an AI problem, and visual regression catches the class of defect functional tests are blind to. See visual regression via PixellPeep.
What makes SaaS different
Multi-tenancy changes the AI design more than anything else. Retrieval has to be filtered per tenant, or an assistant becomes a way to read another customer's data — and that is not a bug you get to fix quietly. Cost changes too: an AI feature has a marginal cost per use, so a plan that was profitable can stop being profitable at the same revenue.
So the first design questions on a SaaS build are tenancy isolation in retrieval, cost per tenant per month, and what the feature does when the model provider is slow. All three are cheaper to answer before launch than after.
Typical work
RAG on product docs or tickets, a scoped agent, and visual regression via PixellPeep. Decision guide: RAG vs fine-tuning for SaaS.
We also build net-new AI SaaS when you are starting a product, not only bolting a model onto an old one.
When we say no
If the AI feature exists to appear on a pricing page rather than inside a workflow someone uses daily, it will not earn its maintenance. If the product has no usage data and no documentation, there is nothing for retrieval to ground against. Both cases end in when not to add AI.
Questions
Where should a SaaS team start with AI?
One workflow that people already perform manually every day, with a measurable outcome. Narrow enough to evaluate, real enough that someone notices if it stops working.
How do you keep tenant data separated in a retrieval feature?
Retrieval is filtered by the same permissions that govern the data elsewhere in the product, so a user cannot reach through the assistant to read another tenant's content.
What does an AI feature cost per customer?
It depends on context size and usage, which is why we log spend per feature from the first week rather than discovering it in a monthly bill.
If the problem maps to work we actually ship, we will say so in 20 minutes.
