Tools · AI SaaS Builder

The scaffolding every AI product needs, already built

Auth, billing, teams, usage limits and model plumbing on day one — so the build starts at the part that is actually yours.

Internal, used on client work Built and maintained by Devute — not resold, and not a white-labelled third party.

Every AI SaaS needs the same six weeks of undifferentiated work before anyone can see the idea. We keep that six weeks built, tested and current, and start your project after it.

Who it’s for

Founders taking an AI product to market who would rather spend the budget on the thing that makes it different.

02 / Capabilities

What AI SaaS Builder does.

01

Accounts, teams and roles

Multi-tenant from the start, because retrofitting it is painful.

02

Billing and metering

Subscriptions, usage limits and overage wired to Stripe.

03

Model routing

Provider-agnostic, with fallback and cost tracking per customer.

04

Evaluation harness

Know whether a prompt change improved anything before it ships.

05

Yours outright

Delivered as your repository. No licence, no lock-in.

03 / Why Devute

What you get that you didn’t last time.

UK-based senior team

You deal directly with the people building your product — same time zone, no quality lottery from anonymous offshore subcontractors.

Transparent pricing

Indicative ranges up front and a fixed-scope proposal after discovery. You always know what you are paying for.

One team, idea to scale

Strategy, design, build and infrastructure under one roof — one accountable team from first sketch to launch and beyond.

You own the code

All source, designs and IP transfer to you, in clean documented repositories. You are never locked in.

06 / FAQ

Questions people ask.

Ask us directly
Can we see it before committing?

Yes. Ask for a walkthrough and we will show you the actual product rather than a slide deck, including the parts that are still rough.

Is it hosted, or do we run it?

Either. We host it for you on our managed infrastructure, or deploy it into your own cloud if that suits your compliance position better.

Can it be changed to fit how we work?

That is usually the point. These start as a working core and get shaped to the business — which is faster and cheaper than building from nothing, and fits better than something boxed.

Who owns the data?

You do, and you can export all of it at any time. UK-hosted by default.

What does it cost?

It depends on how much configuration you need, so we scope it first and give you a fixed number. The conversation and the scoping are free.

Tell us the goal. We’ll tell you the price.

A free audit, a fixed scope and a number — usually within two working days. No obligation, no sales theatre.
