Fintech · sub-niche
Real-time FX rails.
FX is still 2-3 day settlement and 1.5-3% spreads. AI-native FX with sub-second settlement is the next layer.
Team-sized buildTrickle — one deal per quarter
Why now
Stablecoin rails make 24/7/365 FX viable. The non-crypto-facing wrapper layer is unbuilt.
What the signal looks like
Repos with multi-rail (SWIFT + ACH + RTP + stablecoin) settlement, currency-spread libraries, and counterparty risk scoring.

What this displaces
A wire transfer + a 1.5% spread + 'arrives Tuesday.'
Our build-vs-invest call
Capital and regulatory burden are real. Fund only with prior payments background. The wedge is B2B cross-border payments under $100k — the slot Wise dominated retail but mid-market is fragmented.

- Won't Wise win this?
- Wise dominates retail. B2B mid-market is wide open.
