The people
behind the agents.
Opifex is Latin for maker. We’re a small team of engineers and operators who build AI agents and stay accountable for them after they go live.

Most AI projects never reach production. Ours start small, follow your rules and show their work.

We started by telling
a client not to build.
In 2021, Tomas Reid was asked to automate a freight company’s invoices. The demo worked. The numbers didn’t. He told them so, and they hired him to find what would pay back instead.
That first audit became the way every project starts. Cost it first, build one agent, keep a person approving, and show the log. Five years and 41 agents later, the order hasn’t changed.
Four habits,
every project.
01
Cost it first
Every project starts with the numbers, including review time and errors.
02
Start with one
One workflow, one owner, one number to watch. Then grow.
03
A person decides
Agents work inside your limits. Above them, someone on your team says yes.
04
Show the misses
What it got wrong goes in the same report as what it got right.
Every agent has
a person responsible for it.

It flagged three invoices we would have paid twice. Then it told us what it got wrong in week one.

Patients get an answer at 11 at night, and anything difficult still comes to my team.

Clinic manager, Ostler Dental
They told us not to build it. That audit was the best $2,400 we spent all year.

Finance director, Penhale
Fair questions.

We say so in the audit, before there is a build to sell you. About one in five audits ends with a recommendation not to build.
Checks catch most errors before they go out, and every error is logged and counted in your payback. Anything uncertain or over your limit waits for a person.
It stays in your accounts. We use providers that don't train on your data, and we sign your NDA and DPA before we start.
Usually yes. If it has an API, we can connect it. The audit lists what connects and what doesn't.
Four to six weeks for a first agent, including a trial shift next to your team.
You can, and the audit plan is yours to use. Most teams hire us because the hard part is the checks, approvals and upkeep.
