**Icp**: [Accounts Payable Platform](/CompanyTypes/Accounts_Payable_Platform)

## Opportunity Market Sizing

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**S A M**: ~$150M-250M US and European AP automation and B2B payment platforms
**S O M**: ~$15M-30M
**T A M**: ~25,000 global AP platforms, ERP vendors, and enterprise finance hubs × ~$40,000/yr API consumption ≈ $1B
**Growth Rate**: ~14-19%/yr, driven by rising B2B invoice fraud and platform mandates for fully touchless straight-through processing
**Paid Comparable Spend**: ~$75,000-200,000/yr on internal engineering to maintain hardcoded validation rules, legacy OCR data extraction tools, and manual vendor verification labor

## Opportunity Win Conditions

**Kill Thresholds**:
- Integration time > 30 days for mid-market AP platforms
- Straight-through processing rate < 60% on standard PDF invoices
- API latency > 3000ms per payload
- Gross margin < 50% due to underlying compute costs
**Leading Metrics**:
- Time-to-first-production-API-call
- Straight-through processing rate
- Human-in-the-loop escalation percentage
- Daily API payload volume per tenant
- Average API response latency
**What Proves Right**: Early design partners integrate the API into their accounts payable workflows within 14 days and route at least 20 percent of invoice volume through the endpoint. End-users experience an 80 percent straight-through processing rate, prompting platform customers to expand their API tier to the $40,000 annual volume commitment. Net revenue retention exceeds 120 percent by month six as customers decommission custom Python scripts and legacy OCR.
**What Proves Wrong**: Integration timelines stretch beyond 45 days due to complex legacy ERP architectures and security compliance hurdles. The API fails to exceed a 50 percent auto-vouching rate, forcing customers to retain their offshore BPO teams for manual verification. Willingness to pay flatlines at per-seat pricing rather than usage-based API consumption rates, capping ACV below $15,000.
