Featured case study
Rivur manages the money behind resorts and convention centers. We built their web-based systems with tools for budgeting, contracting, invoicing and forecasting, where every figure has to tie back to a contract and an invoice.

Why fintech is different
Money has to reconcile, every change has to be explainable and security reviews are part of every enterprise sale.
02
Audit trails by default
Who changed what and when, recorded for auditors, finance teams and your own support staff.
03
Security reviews close deals
Enterprise buyers send security questionnaires. We build the controls that let you answer them: SSO, encryption, access reviews.
04
Calculations you can trust
Budgets, forecasts, fees and interest tested against real scenarios, because a rounding bug is a finance bug.

FAQ
Something else? Email hello@magmalabs.io.
Do you have fintech experience?
Yes. For Rivur we built web-based systems to manage very large construction projects such as resorts and convention centers, with tools for budgeting, contracting, invoicing and forecasting.
Can you help us with PCI DSS and SOC 2?
Yes, on the engineering side. We reduce PCI scope with tokenized payments and build the controls and evidence a SOC 2 auditor asks for: access controls, audit trails, change history and monitoring. Certification itself comes from your auditor.
Which payment and accounting providers do you work with?
Stripe, Braintree and PayPal for payments, and accounting tools such as QuickBooks. If your provider has an API, we can integrate it.
How do you make sure the numbers are right?
Double-entry ledgers, idempotent transactions, tests around every calculation and automated reconciliation against bank and processor data, with alerts when anything does not match.
Do you sign NDAs?
Yes. We sign an NDA on request, before we see your code or data.
Can your engineers join our team?
Yes. Through Team Embed, senior engineers join your Slack, standups and repo, work U.S. hours and follow your process. Monthly, with 30 days notice, starting in 1 to 3 weeks.
How much does fintech software development cost?
Engineers through Team Embed start at $8,500 per engineer per month. Scoped projects such as a payments integration or a financial platform are quoted as a fixed price after scoping. If your product was built fast or with AI tools, the Production Readiness Audit is a fixed $4,900.
