One engine · and what it makes

We built a deliberationengine. This is what Decabox Foundry does.

First we needed to create the foundation, and the infrastructure to run it. Decabox is that: a foundry, a deliberation machine, a validator. The system that runs it is called the Oracle.

We started with the basics: research, and harness building. Then a new language, written from nothing, because everything we could have built on was made to run fast rather than to be checkable. Then we needed an operating system designed to live inside that language, so that a decision is recorded as it happens instead of audited after the fact.

The Oracle is the system that runs within the Decabox engine. It puts models from different families on the same question and makes them argue from within our harness. This results in a rich and powerful engine. Everything below is that engine, aimed at different problems.

FW.01 · The portfolio

Five solutions, one foundation

Every deliverable starts within the Decabox foundry. We then give it its own scope to grow, with its own customers, and its own character. What they share is the foundation underneath them.

01

AI

the engine in action

Independent checking, on two paths. After the fact: we attack your AI's outputs with multiple model families, none of which built your system, and send back an evidence report with the full receipt trail, the kind a conformity file, procurement review or insurer asks for. Before you publish: Facts Or Fibs? clears every checkable claim in your advertising copy as passed, held, or flagged for a person, each with a dated receipt.

In development

Direct access to the engine: not one model answering, but several independent ones arguing, cross-examining and voting, with the disagreement kept rather than smoothed away. Available live or by API. You get the verdict, the dissent, and the record of how it was reached.

Media

performance, voice & storytelling

A London-based British actor, presenter and voice over artist, with a quarter-century in front of the camera and the microphone and the other 20 sat behind a computer programming. Feature films with Edgar Wright, Ron Howard and Kenneth Branagh; the voice of Nintendo's Legend of Zelda and extensive software development and media production also under his belt.

FW.02 · The foundation

One foundation, many problems

The solutions above are different. What holds them up is not. Every one of them runs on the same foundation, and the foundation is the part that took the longest to get right, because it is the part nobody sees.

Built from the floor up

A language written from nothing, and an operating system made to live inside it. Not a checking layer bolted onto something that was never meant to be inspected.

The bar comes first

We fix what counts as passing before anything is run, then publish what happened. Including the runs that missed.

The disagreement is kept

When the models split we do not average them into one confident answer. The dissent stays in the record, and a person decides.

The long view

We move slowly and with care. A venture only earns its place when it is genuinely ready.

FW.03 · The founder

Founded and run by Stewart Brown

The Foundworks is a one-founder foundry. Every venture on this page is designed, built and held by the same hands, and face!

FW.05 · Questions

The questions we get asked

What does “a Decabox foundry” mean?
Decabox is the engine. The Foundworks is where what it produces is held and sold. Each brand on this page is the same engine aimed at a different problem, not a separate business we acquired. It isn't an agency, and it isn't an incubator for other people's startups: every venture here is ours, built and run in-house.
Are the ventures separate companies?
They're brands under The Foundworks Ltd (company no. 17295591), each with its own name, its own site and its own customers, sharing one foundation of hosting, mail and payments.
Who's behind The Foundworks?
It's founded and run by Stewart Brown, sole director of The Foundworks Ltd. The public record is on Companies House, and there's more on the founder.
How does The Foundworks make money?
Each venture earns on its own terms: Cruxlab on paid reviews, Bizkits on its tools, and the Oracle when it launches. The Foundworks is bootstrapped and self-funded, with no outside investment.
Can I buy something today?
Yes. Cruxlab is open for orders now, with 15 review tiers and secure Stripe checkout from £15, and Verification Lab is open for orders too. Bizkits is in early access, and the Oracle is still in build.
When does the Oracle launch?
It's in build, and there's no public date yet. Its first acceptance campaign passed and we retired it anyway, because the gate had only picked questions every model already answered; the full benchmark, including the runs we failed, is published. Email us and we'll tell you when there's a date.

Our approach

We build solutions then give them a foundation strong enough for it to grow by themselves.
