Engineering for
your industry.

Same engagement model. Different pain points, different stack, different compliance constraints. We name what we'll and won't do in each — no pretending we ship FDA-cleared software in eight weeks.

How the playbooks differ

Same model.
Different defaults.

Fintech needs event-sourced ledgers from commit one. Healthtech needs BAA-signed infra and audit logging. B2B SaaS needs multi-tenant RLS. AI products need evals as a CI gate. Marketplaces need Stripe Connect done right. The engagement model is the same — the defaults inside it shift.

What we won't take

—SOC 2 / HIPAA audit management (we ship the code, not the audit)
—FDA SaMD (510(k)) — specialist firms only
—PCI Level 1 — multi-month dedicated engagement
—Solidity / on-chain contract audits

For Fintech founders

Fintech Founders

Ledgers that reconcile. Stripe + Plaid done right. KYC that passes audits.

Most agencies pitching fintech founders haven't shipped a real ledger. They've shipped a payment integration. Those are different problems and confusing them in your build is how you end up debugging double-counted transactions in production.
