Fintech · sub-niche
Accounts receivable automation.
AR follow-up, invoice routing, payment reconciliation — the workflow no one wants to own.
Month-long buildHot — multiple deals per month
Why now
AI can finally write the 'where's our payment?' email convincingly. Mid-market companies are the buyers — too big to chase by hand, too small for SAP.
What the signal looks like
Repos with QuickBooks / Xero / Netsuite / SAP integrations, email automation libraries, and dunning-flow state machines.
Public examples

What this displaces
A Gmail inbox and three Excel pivots.
Our build-vs-invest call
Hot category. Boring but high-LTV. Fund teams shipping ERP integrations early. The repo pattern to watch: dunning state machines + LLM-drafted emails + payment portal hand-offs.
