FinTech engineering for Amsterdam, shipped without surprises.
Stripe Connect platforms, Plaid integrations, PSD2-aware embedded finance, ledgers that balance. We've shipped the FinTech shape and we know where the edge cases hide. Delivered out of Groningen, same business day as the Zuidas, on-site at your office for kickoff.
What we build
Stripe Connect at platform scale
Connected accounts, payouts, application fees, custom flows, reconciliation. The patterns large marketplaces and FinTech platforms run on Stripe.
Plaid + Tink + Trustly
PSD2-aware account access, AIS / PIS flows, EU + UK provider coverage. We've integrated the major rails and know each provider's quirks.
Double-entry ledgers
Internal ledgers, reconciliation against PSPs, dispute handling. Audit-grade Postgres schemas, not denormalised spreadsheets.
Compliance vocabulary
KYC / KYB flows, sanctions screening hooks, transaction monitoring, audit trails. We speak the AFM + DNB vocabulary buyers care about.
Where this fits
You're an Amsterdam neobank or embedded-finance scale-up and your engineering team is two senior FinTech specialists short.
You're a marketplace adding payouts and you want a Stripe Connect rollout from a team that has shipped this exact pattern five times.
You're a Series B SaaS adding billing complexity and the in-house team's bandwidth is gone.
