The finance AI problem
Your board wants AI in finance. Your auditors want it to hold up.
You are under pressure to automate, but finance does not run on “probably.” An LLM that invents a number, silently cuts a corner, or cannot show its work is not an efficiency gain. It is a liability you have to sign your name to at close.
There is a fourth option.
DIY agents and scripts
Sharp operators can vibe-code something useful, until it drifts, breaks, or leaves with the person who built it.
Doing nothing
Your team keeps burning days on report pulls, reconciliations, approvals, and copy-paste between systems.
What Loopfour is
Deterministic workflow automation for finance.
Loopfour automates your most painful finance workflows as deterministic, auditable code, not black-box AI, on top of the tools you already use.
Real code, not runtime guesses
Every workflow runs step by step as predefined code. It behaves the same way on run #1 and on run #1,000,000.
Scoped AI where it belongs
AI can read a contract or classify a document, but confidence thresholds and human fallback keep it from deciding what your finance system does.
Full execution evidence
Every action, approval, exception, and system write is logged so finance leaders can inspect the run instead of trusting a black box.
From one painful workflow to automation in about two weeks

Deterministic finance automation
You name the workflow. We build it, run it, and keep it running.
A screen-share or Loom is enough. Our finance engineers deploy against your existing stack, including tools with no API, then maintain the workflow as your systems change.
Walk us through the month-end pull, credit-memo back-and-forth, AR inbox, or other workflow your team dreads. You do not build anything.
When a contract is signed, extract billing terms, match the CRM account, generate the invoice, and route anything uncertain to the controller.
Parsed into trigger, extraction, validation, exception, and sync steps
Loopfour turns the walkthrough into deterministic workflow code with triggers, extraction, validation, exception routes, and sync steps.
- Event trigger configured
- Rules and thresholds mapped
- Exception route added
- Dry run ready for approval
Approve a dry run, watch it in observability mode, then let it run on events while exceptions wait for human approval.

One finance portal
Stop running finance across five disconnected tools.
Your automations are scattered across AI tools, scripts, and spreadsheets. Loopfour unifies finance workflows into one governed portal with live triggers, controls, and audit-ready exception handling.
Why deterministic matters
An AI agent cannot pass your audit. Loopfour can.
We use AI where it belongs, such as interpreting a document, but never to decide what your finance system does.
AI agents
Loopfour
Decide what to do at runtime and can hallucinate a step or tool.
Runs predefined, programmatic steps with no surprise actions.
Drift or cut corners after enough runs.
Executes identically on the first run and the millionth run.
Hide their reasoning inside the model.
Surfaces every step in an execution tree and audit trail.
Ask you to trust that the right thing happened.
Leaves you with proof that the right thing happened.
DETERMINISTIC AUTOMATION
A workflow run your controller can inspect.
Not a chatbot. A controlled workflow engine for finance operations that follows configured rules, catches exceptions, and keeps every action reviewable.
Workflow run
Cash application flow
Match incoming payments from our processor and bank lockbox to open invoices in the ERP. If confidence is above 95%, post automatically. Otherwise, flag for review and notify the AR team in Slack.
Built your deterministic workflow - 6 steps, 2 data sources, 1 exception route.
- Triggers: payment event + bank sync
- Matching: Invoice number, amount, customer ID
- Auto-post: GL entries for high-confidence matches
- Exception: Routes low-confidence to AR queue
- Notification: Slack alert with match details
Proof & results
Built by finance operators. Deployed in companies that get audited.
6 days -> 18 minutes
Billing process compressed
A $75M ad company moved a billing process that touched 25 people over six days into an 18-minute workflow where only exceptions reach a human.
No API? No problem.
Homegrown billing automated
An approximately $85M legal marketplace automated billing from a homegrown system with no API through secure browser automation.
Audit-ready by default
Public-company controls
A public company on Workday runs Loopfour with SOC 1 evidence captured on every workflow run. SOC 2 Type II and HIPAA are already in place; SOC 1 is underway.

Workflow Engine
You stay in control
We carry the maintenance.
Loopfour sits between the systems you already trust and turns repeatable finance work into governed workflows your team can inspect.
Permissions, approvals, impact analysis, and a full audit trail: see how governance works.
Explore governanceNo rip-and-replace
Keep the ERP, CRM, payment processor, document tools, and approval process your team already uses.
No key-person risk
Workflows live in a managed platform with version history, not in one analyst’s local script or private prompt chain.
No maintenance burden
When an upstream tool changes or repeated exceptions show a rule needs to change, Loopfour handles the update with your approval.
Gated by design
No workflow goes live without the approvals your controls require, and exceptions wait for the right owner before anything posts.
FAQ
Common questions from finance leaders.
No. Loopfour execution is programmatic and deterministic. AI is called only for specific steps that need interpretation, such as reading a contract, with confidence thresholds and human fallback.
