PRODUCT · AI FRAUD DETECTION
Catch expense fraud before it's approved. Not during the audit.
The ACFE 2024 Report found the median company loses 5% of annual revenue to occupational fraud. Most expense tools flag fraud during audit — months after payment. REME flips the order. Seven AI agents check every claim in under 200 milliseconds, before the money ever moves.

The Problem
By the time your audit catches it,
the money is gone.
Every traditional expense tool — Concur, Expensify, Ramp, Brex — flags fraud during audit. The forensic flag arrives in Q3 for an expense paid in Q1. The employee has been reimbursed. The money has cleared. The "fraud detection" feature surfaces a problem that's already cost the company.
Recovery requires confronting the employee, escalating to HR, and often legal action. Most companies just absorb the loss. The ACFE estimates a median loss of $125,000 per fraud incident — and that's just the cases that get reported.
The window to stop fraud is the 200 milliseconds before approval. After that, you're paying lawyers.
$125,000
ACFE 2024 median loss per occupational fraud incident. Expense reimbursement is among the top three vectors.
The Flip
Every claim. Every check. Before approval.
REME's seven AI agents run in parallel on every single claim — not a sample, not a flag-on-anomaly, every single one. The combined latency is under 200 milliseconds, faster than the WhatsApp message takes to deliver.
Suspicious claims are quarantined for finance review. Clean claims route to manager approval. The fraudulent payment never happens — because the system never lets the claim become a payment in the first place.
Traditional expense tools
Fraud detected 90 days after payment. Recovery requires legal escalation.
REME
Fraud caught before payment. No recovery needed.
Seven specialized AI agents.
One unified verdict.
Each agent is built for one specific fraud vector. Each runs in parallel. Each returns a confidence score and reasoning. The combined system catches patterns no single rule engine can find — and gets more accurate on your specific employees and vendors over time.

Multi-Currency Validator
Verifies exchange rates against historical ECB rates on the date of expense.

Duplicate Matcher
Perceptual-hash matching catches the same receipt photographed from different angles, weeks apart, by the same or different employees.

Data Consistency Verifier
Cross-checks merchant, date, amount, and category for internal contradictions on the receipt itself.
Catches:

- Same expense across two reimbursement systems
Image Forensics
Detects digital editing, altered totals, photoshopped fields using vision-language model analysis.
Catches:
- Receipt totals digitally altered

Contextual Grouper
Identifies suspicious patterns across claims — round numbers, threshold-gaming, weekend "client" meals with no client named.

What it looks like in practice.
Three real fraud catches from REME-protected accounts. Names anonymized, scenarios real.
The $850 hotel bill submitted twice — six weeks apart.
A senior sales rep submitted a $850 Conrad Bangkok hotel bill on 12 March. Six weeks later, after a different trip, they submitted what looked like a different receipt — different photo angle, different timestamp, different colored ink. Agent 03's perceptual hash caught it instantly. Same receipt. Quarantined for finance review before approval.

The "$240" dinner that was actually $24.
An engineer submitted a Singapore restaurant receipt for $240 — claimed it was a client dinner. Agent 06's image forensics flagged a 0.94 anomaly score on the total field. The "240" had a slightly different pixel sharpness than the rest of the printed text. Original receipt, recovered from an unedited photo elsewhere on the device, was $24.
$216 saved · Caught at submission · Triggered policy review of all claims from the same submitter.
The team lunch claimed by three different people.
Three sales engineers attended a team lunch in Mumbai. The bill — $180 — was paid by one of them. All three tried to claim reimbursement, each saying the lunch was for "client meeting." Agent 03 matched the receipt across all three submissions within 200ms. Two were instantly rejected. One was confirmed as the actual payer.

The longer you use it,
the better it gets at catching your fraud.
REME's fraud engine isn't a fixed rule set. Every claim — flagged or clean — feeds back into your company's private model. Patterns specific to your industry, your vendors, your employees' behavior become part of the detection logic over time.
After 90 days, REME knows your "normal." After 180 days, it knows your specific employees' submission rhythms, your common merchants, your travel patterns. Fraud that would have looked like noise on day one looks like signal on day 180.
Your data trains your model. Not other companies' models. Tenant isolation is hardcoded.
Detection accuracy over time
Industry baseline shown as horizontal dotted line at 88%. Above the line means your AI is catching what other companies' AI misses.

FAQ
AI fraud detection, common questions
REME runs seven specialized AI agents in parallel on every claim, in under 200 milliseconds. Each agent checks a different fraud vector — currency integrity, perceptual-hash duplicate matching, data consistency, image forensics for altered receipts, and contextual pattern detection. The combined system catches duplicates submitted across angles, altered totals, cross-employee collusion, and threshold-gaming patterns no single rule engine can find.
Traditional expense tools flag fraud during audit — typically 30–90 days after payment. By then the money has cleared, the employee has been reimbursed, and recovery requires legal escalation. REME flips the order: every claim is screened in 200ms before approval. Suspicious claims are quarantined, not flagged after the fact. The fraudulent payment never happens.
REME's combined seven-agent system has a measured 99.7% detection accuracy, with false-positive rates under 0.5% on typical company data. Suspicious claims are quarantined for finance review (not auto-rejected) so even rare false positives are caught and corrected by humans before any employee is impacted. Employees never see the fraud agents directly — there's no friction on their end.
Agent 03 (Duplicate Matcher) uses perceptual-hash matching with 99.6% accuracy on visually-identical receipts photographed from different angles, in different lighting, even after slight rotation or color shift. It also catches same-receipt submissions across different employees within 200ms — a vector traditional duplicate-detection-by-merchant-and-amount completely misses.
REME catches the most common documented fraud vectors — duplicates, inflation, alterations, currency mismatches, threshold-gaming, cross-employee collusion. It cannot catch fully fabricated expenses backed by a fully fabricated supporting receipt that's never been seen before — those require human investigation. No system catches 100% of fraud, but REME typically reduces expense fraud losses by 70–85% versus manual review.
The seven-agent architecture is the same. The model behind each agent is fine-tuned to your company's data over time — your vendors, your employee submission patterns, your industry's common fraud signatures. Tenant isolation is hardcoded. Your model never trains on or sees other companies' data.
Yes. As part of customer onboarding, REME runs a forensic audit on the previous 12 months of expense claims (with your permission). The AI agents check historical data and surface suspicious patterns, duplicates, and anomalies you may not have caught. Most companies discover 5–15% more fraud in the historical audit than they were aware of. Recovery actions are your call — REME provides the evidence.
After 90 days, the model has learned your normal submission rhythm and most common merchants. After 180 days, employee-level patterns are integrated. After 365 days, accuracy reaches 99.7% on company-specific patterns. The improvement is automatic — no configuration required.
Yes. REME is SOC 2 Type II and ISO 27001 certified. Every detection decision is logged with full reasoning, agent confidence scores, and timestamp — providing a complete audit trail. The system supports retention requirements for IRAS, ATO, HMRC, IRS, and other major tax authorities (default 7-year retention, configurable). Audit reports are exportable on demand.
