AI you can check.
Models are getting smarter and cheaper every month. What they don’t know is your business. We build agents that learn it one job at a time, and show their work on every case, so you can check it.

How we think about AI
Intelligence is getting cheap. Trust isn’t.
Every few months the models get better and cheaper. What doesn’t come in the box is your business: your suppliers, your exceptions, the way your team decides when something looks off. That is where AI either earns its keep or makes expensive mistakes quietly.
So we never start with a model. We start with a job: one task your team does today, with a right answer we can check against your own history. The intelligence in our system is three things working together: the model, the rules your team has taught it, and the record of every case it has handled. Models change. The rules and the record are yours, and they compound.
And autonomy is earned, not switched on. An agent starts by suggesting, moves to acting with your approval, and runs on its own only when its record says it should. Job by job, never all at once.

- 02Your rules and your record are the asset.
- 03Autonomy is earned.
- 04Every decision leaves a trail.
Each agent does one job. You see all of it.
That starts with a narrow job: one task your team does today, with a right answer we can check. An agent reads from your systems and does a defined task. When it isn't sure, it doesn't guess: it asks your Cornermark lead or you. Your answer becomes a rule, so it never asks the same thing twice.

Proof on your past cases, before anything goes live.
Trust is earned before go-live, not after. We run the agent on work your team already did and compare its answers to theirs. You set the accuracy bar. If it falls short, it doesn't go live, and you don't pay for go-live.

You see every run.
And it stays earned: every case leaves a trail. Every run is logged: what the agent read, what it decided, and what it cost. You can open any one and follow it step by step. The cost of each case is tracked from day one.

The right model for each job.
The model is the replaceable part, so we choose it like any other cost. We test the leading models on your own cases and pick per job. Not on price per call, but on what each case really costs you: the model plus the time your team spends fixing its misses.

No connector? We build one.
Plenty of the systems that run a business never made it onto anyone’s integration list: an older ERP, a supplier portal, a nightly export file. We build a read-only connector for it, test it on your real data, and monitor it like the rest.

Scoped and priced up front, like everything we do.
Your data, handled like it's ours to lose.
Which is why we read only what a job needs, log every access, and never let a model train on your data. Six questions every owner asks, answered plainly.
We connect read-only. Data is encrypted in transit and at rest, in a named cloud region.
Only the named people on your engagement. Every access is logged.
No. We use providers' business services, whose terms bar training on your data.
For the engagement plus a stated period, then it's deleted. Ask for deletion any time.
You can switch off our access in one step, and every agent action is in the run log.
Yes. Open any run: what it read, what it decided, what it cost.
Sensitive data, case by case
Health data (PHI)
We don't touch patient records until a Business Associate Agreement is signed and the work runs on HIPAA-eligible infrastructure. Until then, we work on de-identified data.
Payment card data
Card numbers never enter our systems. We read settlements and payouts, never the cards themselves.
Personal data (GDPR / CCPA)
We process it only for your engagement, honour deletion requests, and keep a list of every subprocessor.
Financial records
Read-only access, every read logged, retained only for the engagement.
