Accounting
Ai that works the same way. every time.
Stop guessing. Start knowing.
Fierce runs deterministic workflows on your own servers.
No hallucinations, no drift, no black boxes.
Built for firms that have to show their work.
The real problem with Aiin regulated industries.
Generalist AI wasn't built for firms that have to prove what happened, when, and why.
Unpredictable sample
Ask it twice. Get two answers.
Same input, different output. General AI can't pass an audit.
Uncontrolled
Data you don't control is a liability you didn't sign up for.
Your client data, processed on someone else's servers. Every time.
Unaccountable
When it fails, you're the one who signed off.
When something goes wrong, you can't explain what happened.
Ai that earns its placein your workflow.
Four commitments, engineered into the product.
Deterministic
Locked workflows.
Define the process once. It runs identically every time — same inputs, same outputs, same logic. No variance. No surprises.
Private by design
Installed on your servers.
Your data never leaves your infrastructure. Full ownership, full control. Compliant by architecture, not just by policy.
Auditable
Every step, on record.
Full trace of every workflow run. Who triggered it, what it did, what it decided. Ready for your auditors before they ask.
Measurable
AI you can report on.
Know exactly what efficiency you’re gaining. Quantify performance, track improvements, prove ROI to leadership.
Built for the industrieswhere accuracy isn’t optional.
Different industries, same standard.
Healthcare
A misread chart isn't a bug.It's a patient at risk.
Coming soonLegal
A missed clause isn't a glitch.It's a client exposed.
Coming soonFinancial
A wrong number isn't noise.It's a compliance breach.
Coming soonInsurance
A bad claim call isn't random.It's a lawsuit waiting.
Coming soonYou define the rulesFierce follows them.
Three steps from workflow to production. No black box in between.
Map your workflow
Define every step, decision, and handoff before anything runs. If it's not mapped, it doesn't happen.
Deploy your infrastructure
Fierce installs on your servers, inside your existing stack. Nothing routes through a third party.
Run. Measure. Improve.
Every run is logged, traceable, and measurable. Review performance, refine the workflow, prove the value.
Your infrastructure.Your data.
Multi-factor Authentication
Add an additional layer of security to your account by requiring a second factor to verify your identity.

Compliance used to mean slowing everything down. Fierce is the first AI infrastructure we’ve trusted with client data — it’s given us the speed without the risk.

You’ve got questions.We have the answers.
A system prompt is a suggestion — the model can still drift, hallucinate, or interpret it differently on different runs. Fierce locks the workflow itself. Same steps, same logic, same output, every time. That's the difference between "usually right" and "provably right."
It means the workflow runs the same way every time it's triggered — same inputs produce the same outputs, following the exact logic you defined. No creative interpretation, no variance between runs. If something changes, it's because you changed the workflow, not because the AI decided to.
Fierce installs inside your existing infrastructure. Your data never leaves your environment, and nothing routes through a third-party cloud. If you don't currently have the infrastructure for this, we'll help scope what's needed during setup.
Xero, MYOB, QuickBooks, Sage, Handisoft, APS, BGL 360, and Class Super, among others. If your practice runs on something not listed, ask — we're adding integrations as we onboard new firms.
You update the definition, and the change applies from that point forward — deterministically, like everything else. Nothing shifts on its own. Every version of a workflow is logged, so you can see exactly what changed and when.
We map your existing workflow first, then deploy the infrastructure inside your systems. Timelines depend on complexity, but most firms are running their first live workflow within weeks, not months. Happy to give you a real estimate on a call.
