FinTech software, deep in five verticals

Generalists build generic things. Each of these verticals is a swamp of vendors, regulations, and edge cases — it took us years to map them. If your product lives in one, we’re already most of the way to a deploy.

Banking & Neobank Software

Challenger banks, Banking-as-a-Service partners, and the rare community-bank modernization. We work with sponsor banks, not around them — and we know the 400-question diligence packet by heart.

I/03 — PAYMENTS18 platforms shipped

Payments & Money Movement

Moving money is easy. Moving money correctly — idempotent, reconciled, observable, refundable, regulated — is what we do. We’ve shipped on Stripe, Modern Treasury, Increase, Adyen, and four sponsor banks directly.

  • Multi-rail orchestration — ACH, RTP, wire, FedNow, cards, cross-border. One API, one ledger.
  • Idempotency throughout — retries are safe, replays are expected, double-debits are impossible.
  • Real-time reconciliation — streaming, not batch. Your CFO knows the number now, not tomorrow.
  • PCI scope reduction — cardholder data out of your application surface; tokenization done right.

I/04 — WEALTH8 platforms shipped

Wealth & Investment Management

Brokerage, advisory, and custody platforms. RIA back-offices that don’t melt at year-end. Self-directed surfaces that pass FINRA Rule 2210. Robo-advisory engines that explain their math.

  • Portfolio management — rebalancing, performance attribution, fee billing.
  • Robo-advisory platforms — model portfolios, tax-loss harvesting, rules engines.
  • Client dashboards — performance reporting that explains, not just displays.
  • FINRA 2210 review tooling — communications stored WORM, indexed for retrieval.

Adjacent verticals

Specialized work in three more spaces

Insurance, trading, and crypto. We’re selective about what we take on here — the rules are different and the failure modes uglier.

Insurance Tech

Claims processing, underwriting automation, and the policy admin portals adjusters actually want to use. P&C, life, and embedded.

  • Claims processing systems
  • Underwriting automation
  • Fraud detection engines

Trading & Capital Markets

Order management, post-trade settlement, market data, and risk dashboards. FIX-protocol fluent, low-latency where it matters.

  • Trade execution platforms
  • Post-trade settlement
  • Risk & compliance dashboards

Crypto & Digital Assets

We take work in regulated stablecoin payments and crypto compliance tooling. We turn down speculative trading platforms.

  • Stablecoin payment systems
  • Digital asset wallets
  • Crypto compliance tooling
Cross-cutting regulatory layer

Every vertical lives under the same regulators

We’ve never lost a SOC 2 audit, blocked a sponsor-bank diligence, or surprised a regulator. Quality-of-architecture is a compliance feature.

BSA
Bank Secrecy Act. SAR/CTR pipelines, customer due diligence.
AML
FinCEN-aligned monitoring, tuning, case management.
OFAC
Sanctions screening at every money movement.
SOC 2
Type II. Controls encoded; evidence automated.
PCI
Scope-reduction first. Cardholder data out of app.
GLBA
Safeguards rule. Encryption at rest and in transit.
FINRA
Rule 2210 communications, books & records (17a-4).
CCPA
Consumer-data rights baked into the data model.
