Verified beats fast
A run that checks its own work is worth more than one that finishes first. Every action is confirmed on screen before the next one starts.
AI is the brain.
We are the hands and the eyes.
Models got good at reasoning long before anything got good at acting. Twennyfour exists to close that gap — reliably enough that a firm can put its books behind it.
Why we build this
Thinking and doing are two different jobs.
A model may reason, hesitate, even change its mind. That is fine for thinking. Execution should never miss. The moment a system touches a ledger, a customs filing or a payroll run, "usually correct" stops being a feature.
So we split the two. AI learns the interface and repairs it when it changes. A deterministic engine does the acting — the same verified path, every time, on your machine, while you watch and keep the last word.
It starts with business software, because that is where the waste is loudest: entire afternoons spent moving numbers between screens that were never meant to talk to each other. It doesn't end there. Anything a person operates through a screen is, eventually, in scope.
How we build
Four rules we don't trade away.
Your data stays yours
Execution is local by design, not by configuration. If a feature would require sending your screens to us, we don't ship that feature.
Stop, don't guess
When the screen is not what we expect, the honest answer is to halt and say so. Silent improvisation is how automation loses trust.
Humans sign
The engine handles the typing. The judgement, the exceptions and the final approval stay with the person whose name is on the file.
Who is building it
Small team, Montréal, close to the users.
Twennyfour was founded in 2026 by Ilias El Benani, engineering student at Polytechnique Montréal, after watching accounting and logistics teams spend their days retyping what a machine could have typed — inside software that offered no way in.
We are early and we say so. The product is being built with a small number of design partners who get direct access to the person writing the code, and whose workflows shape what ships next.
Design partner program
Give us your team's most hated 30 minutes.
A simple trade: you show us one painful task, we show you whether the engine can take it — and if it can, we build it with you, free.
01
Tell us the task
A 20-minute call or a quick walkthrough of the repetitive software workflow your team dreads most.
02
We map the workflow
We configure the deterministic blueprint for your specific application using test data and safe environments.
03
Live pilot demo
You watch the engine execute the exact workflow on screen with verified stop points and zero hallucination.
04
Deploy together
Design partners shape the platform, keep direct founder access, and pay nothing during the pilot phase.
