Fintech software development priced like a fixed-rate loan — not an open line of credit.
Custom fintech software for the lending shop, advisory firm, or founder tired of renting seats. Built in Austin, on the rails you already trust — Stripe, Plaid, your bank. The security work is inside the fixed price — not sold back to you as a surcharge.
What a five-person shop rents, posted to one ledger.
Vendor-published prices, August 2026. No firm runs all four lines — find yours, then read the credit side. Every debit below posts again next month, forever.
BALANCE NOTE: THE DEBIT COLUMN NEVER CLOSES — SEAT SIX RAISES IT, YEAR FOUR EXTENDS IT. THE CREDIT LINE CLOSES AT HANDOFF. STRIPE'S 2.9% + 30¢ STAYS EITHER WAY — THAT'S THE FAIR PRICE OF CARD RAILS, NOT THE PART WORTH REPLACING.
The risk isn't the code. It's who holds your ledger.
Finance people underwrite counterparties for a living — then run the firm on rented software from vendors whose balance sheets they've never seen. The recent record — all of it public, 2024–2025:
The banking-middleware vendor behind Yotta and Juno went under. 100,000+ Americans were locked out of roughly $265M for months, and $65–96M of it was never found. The company folded with nothing left to repay — eighteen months on, customers were still waiting to be made whole.
The partner bank behind a raft of fintechs was hit by ransomware. By its own disclosure, 7.6 million people were affected; Affirm, Wise, and Bilt customers were among those notified.
The banking-as-a-service startup that called itself "the AWS of fintech" raised $81M, then shut down with three employees left. Every client had to migrate off, on the vendor's clock.
Every rented dashboard is a dependency with a balance sheet you can't audit. You can't drop your bank or your card processor — that plumbing is worth keeping. But the thin SaaS layer between you and them, the $350-a-seat middle? Code you own can't go out of business.
EXPOSURE AFTER HANDOFF: YOUR REPO, YOUR DATABASE, YOUR SERVER — COUNTERPARTY: NONE →Fintech app development on rails that already carry money.
We don't rebuild banking infrastructure, and neither should you. Money keeps moving through your bank, Stripe, your processor — companies built to hold it. What we build is the layer that's actually yours: the portal, the workflow, the reporting nobody rents at your size.
RENT IT — GLADLY
OWN IT — ONCE
NOT ONE OF THE TEN AGENCIES ON PAGE ONE NAMES STRIPE OR PLAID IN ITS PITCH — THEY SELL SWIFT AND CORE-BANKING MIDDLEWARE TO BANKS. YOUR SHOP RUNS ON THESE RAILS ALREADY. TURNING THE TOOL INTO A PRODUCT LATER IS OUR SAAS SIDE; A CLIENT PIPELINE AROUND IT IS A CUSTOM CRM; A 2009 SYSTEM UNDERNEATH IT ALL IS OUR LEGACY DESK.
Built like the money depends on it — because it does.
Agency pages greet a five-person firm with a wall of acronyms. Skip the wall. Here's what the security work actually is, in developer terms — and it ships in every build, not in a premium tier.
Encryption in transit and at rest. Role-based access, so the new hire sees less than the partner. MFA on every login. And an append-only activity log — who touched what, when, answerable in one query, years later.
Card numbers and bank credentials never live on your server. Stripe and Plaid hold them in their vaults; your system holds tokens that are useless anywhere else. Identity checks are rented by the check — Stripe Identity posts $1.50, Persona's startup tier runs $1–$1.50 — never rebuilt from scratch.
Exportable reports, tested backups, and history that can't be quietly edited. When a partner bank or a big client sends its security questionnaire before a deal, the answers are already true — nothing gets bolted on in a panic the week before signing.
Every entry final. Nothing rebilled.
Hourly fintech consulting is an open line of credit against your project — US shops meter $100–$300 an hour and the balance compounds until someone says stop. This is the other instrument: one rate, one term, a log you can hold us to.
And it's built in Austin — a town of roughly 767 fintech startups by Tracxn's count, where the famous shops run 120-person benches through three time zones. Here, the person who quotes the system writes the system. In Central Time. That's the whole org chart.
1A.What does fintech software development actually cost here?
$16,500 to $50,000, fixed, depending on scope — the quote you get in 24 hours is the number. For contrast, the one agency on page one of Google that prints anything shows $100,000–$2,000,000+, and the published MVP guides start at $50,000 with offshore delivery. And if a $39 seat of Redtail genuinely solves your problem, rent it happily — the build is for when the seat math breaks or the workflow was never in anyone's catalog.
1B.Can one developer really handle a build where money moves?
The heavy machinery was never going to sit on anyone's desk — it lives at your bank, at Stripe, at the identity API: companies with thousands of engineers whose only job is holding money and credentials safely. What's left is what one senior developer does best: clean data models, encryption, access control, an activity log, and scope that doesn't drift. Ask what "3,600 fintech experts" means for a $30,000 project — a rotating bench. Here, the person who scoped the system writes it, and an NDA is standard if you want one.
2A.What happens to the data in the tools we run now?
It comes with you. Exports from the CRM or loan software you're leaving, the statements, the spreadsheets with the real numbers in them — we import, dedupe, and reconcile them against each other, and the old tool stays read-only until a full cycle closes clean. Migration is written into the fixed quote like everything else. A build that ignores your history isn't a system — it's a demo.
2B.Who owns the code — and what if you get hit by a bus?
You do, from the first commit: repo, database, server, docs, all in your accounts at handoff. It's standard boring stack — Go and PostgreSQL — that any competent developer can pick up, which is the real bus insurance. Compare the alternatives you'd otherwise sign: platform source-code licenses, or a 36-to-60-month LOS contract with non-refundable setup fees. Nothing here locks, licenses, or renews.
3A.Can you build the customer-facing fintech app too?
Yes — fintech app development is the same build with a public face: borrower portals, client dashboards, payment flows your customers touch from a phone. It ships as a fast mobile-ready web app, which for a firm your size beats maintaining two app-store binaries. If it's meant to become a product you sell, say so in the application — that changes the scope conversation, not the price logic.
3B.Why is this cheaper than every fintech agency — what's the catch?
The catch is scope, stated plainly: this is a focused system for one firm, not a neobank. No 40-person team to feed, no office in three countries, no discovery phase billed at $30,000 before code exists. One senior developer, rails that already work, 7–12 weeks. If your project genuinely needs a core-banking rebuild or a trading engine, you need one of the big shops — and their prices start to make sense at that scale.
