AI-Native Operating System for the Finance and Operations Stack.
One runtime. One model layer. One memory. One audit trail. Every agent your finance & ops team will ever run.
Mirian AI is the agentic operating system that sits on top of your existing finance and operations stack. Instead of replacing your systems, Mirian connects directly to your ERP, HRIS, and bank feeds to automate your most time-consuming workflows. Mirian deploys ledger-grade AI agents to close your books, optimize working capital, and build real-time cash forecasts. You get the power of automated execution, protected by strict human approval gates and a permanent audit trail, and the ability to build future operational agents on the exact same infrastructure.
One runtime. Four agentic modules live. More deploy on the same stack.
Mirian sits securely on top of your existing ERP, HRIS, and bank feeds to automate your most time-consuming workflows. Today, four ledger-grade agents run in production, handling your financial close, AR automation, AP optimization, and cash forecasting under strict human approval gates. But we didn't just build four finance tools. This underlying infrastructure is architected to launch every future finance and operations agent your team will ever need, allowing you to instantly deploy new capabilities without ever adding a new software silo.

01Financial Close Automation
Compress your close timeline to low single-digit days with agentic close automation.
The Financial Close Agent securely accelerates your close cycle by connecting across multiple source systems. The module leverages an intelligent engine that learns your unique transaction patterns to handle reconciliations, auto-calculate accruals, and draft journal entries. Everything is routed through your exact preparer and approver workflows to deliver an audit-ready close package complete with supporting evidence.

05Mirian Pulse
Your always-on AI copilot. It remembers everything your modules learn.
Mirian Pulse holds accumulated context across every module, including close, receivables, payables, and cash, with months of institutional memory built in. Ask a question in plain English and it doesn't just look up the answer: it pulls from live data, runs the analysis, and models what-if scenarios on the spot.

Mirian operating system
One OS underneath every module.
One operating system built to stand up every finance and operations agent you will need, with eight architectural decisions that make them safe to run on any general ledger.
One runtime
Every agent. One stack.
All four modules run on a single shared runtime: one memory, one set of controls, one audit trail. New agents deploy on the same stack, not as another disconnected tool.
Four modules liveNew agents slot in
Deterministic math
The AI never authors a number.
Agents reason and decide; deterministic code executes every calculation, reconciliation, and journal entry. Exact, replayable, audit-ready, every time.
Code computesAgents reason
Company brain
It gets sharper on your books every cycle.
Every close, mapping, correction, and approval becomes accumulated context. Mirian doesn't just store your history; it surfaces the right context to drive smarter decisions.
Institutional memoryAccumulated context
Canonical data model
Your whole stack, one model.
ERP, HRIS, payroll, bank, Excel: every source system normalizes into one canonical model the agents work from. New systems slot in as connectors. You never re-platform.
Connect, don't migrateWorks with your current setup
Model-routed
Never hostage to one AI provider.
Mirian routes each task across frontier models for cost, capability, and resilience. Your finance logic lives in Mirian's tools, not in any single vendor's model.
Provider-independentBest model per task
Ground-truth tested
Proven against the answer key.
Agents run full closes on complete synthetic companies with hidden ground truth, and we verify every output against the known answer before it ever touches your books.

Human in the loop
The agent works. You stay in control.
Approval gates, preparer and approver workflows, and a full audit trail protect every write: who, what, when, agent versus human. Everything is exportable for your auditors.

Built for what's next

“Mirian took over the three things that ate our month: closing the books, chasing receivables, and rebuilding the cash forecast. My team got a full week back every month. The agents do the work; we approve it — nothing posts that we haven't signed off on.”
