AI-native
delivery
AI in the loop from spec to ship: generation, review, refactors, tests, docs. Faster than agencies built before the AI era, with the review discipline a working product needs.
Ship FinTech features that meet compliance, not despite it.
Plaid integrations, Stripe Connect, PCI-aware data flows. Senior engineers who've shipped financial software end to end. One subscription, pause any time.
Subscription, fixed build, or white-label, depending on the work.
See all ways to workThe patterns we ship for FinTech teams
FinTech is the category where 'shipped fast' and 'shipped wrong' have the highest cost differential. Every pattern below was learned in production, under audit pressure, with real customer money in flight.
01
PCI DSS scope minimization
We tokenize, we never store. Stripe, Adyen, or a custom PSP, the principle is the same: keep PCI surface area near zero.
02
Plaid + Stripe Connect
Bank linking, KYC, KYB, account-to-account payments, marketplace payouts. The integrations that anchor most FinTech stacks.
03
Audit trail by design
Immutable event logs, queryable from day one. Auditors don't ask for evidence; they read it.
04
SOC 2 evidence in code
Access reviews, change management, vendor monitoring captured as automated artifacts, not after-the-fact scrambles.
05
HIPAA-compliant patterns
For products where finance touches health. PHI handling, BAA partners, encryption-at-rest defaults.
06
Ledger-aware data models
Double-entry accounting primitives that survive reconciliation. Money math that doesn't round-trip incorrectly.

Financial software that works, and scales
Engineering that ships features with compliance and reliability baked in.
Real
software
Architected, reviewed, tested, owned. Software you can keep, maintain, and hand over. Not demoware, not prototype code that ships, not unreviewed AI output sent to your customers.
Visible
progress
Progress you can see as it happens, not at quarter-end. Working software, not a slide deck. Pause anytime with 7-day notice.
End-to-end
ownership
Accountable for what ships, not what gets coded. Discovery, design, build, deploy, maintain. One team that owns the outcome.
Frequently asked questions for FinTech
01
How fast will I receive results?
We usually start the same day after onboarding. You'll see progress daily and weekly, with features and improvements delivered continuously based on your backlog and priorities.
02
Who will work on my product?
Senior software developers, 8+ years in production, with AI in the loop end-to-end. We use the AI tooling, we own the architecture, and we sign the review on every PR. Stacklane takes full responsibility for delivery.
03
Is there a limit to how many requests I can make?
No, you can submit as many requests as you want.
04
How do you handle larger requests or features?
Large features are broken down into smaller milestones and delivered step by step. You always see progress and can adjust priorities as we go.
05
Can agencies use this as a white-label solution?
Yes. Agencies can work with Stacklane as a technical partner and offer our software services under their own brand if desired.
06
What if I only have a single request or small project?
We also offer one-off projects with fixed pricing. If you don't need ongoing development, a one-off project may be a better fit.
07
What if I don't like the result?
We work closely with you and iterate based on feedback. Our goal is to build software that fits your needs, not just deliver code.
08
Are there any requests you don't support?
We focus on software development and product design. We are not a good fit for simple marketing websites, very small design-only tasks or non-software services. If you're unsure, we'll help you determine fit during the discovery call.
09
How do we communicate and request work?
You submit requests through a shared backlog or project board. We communicate through tools like Slack, email, and regular check-ins.
10
How does pricing work?
Stacklane works on a flat monthly subscription: predictable pricing, no hidden fees, no long-term contracts. You can scale up, pause, or cancel at any time.
11
Are there any refunds?
We don't refund time already worked. Pause or cancel any time to avoid future charges; both take effect from the next billing cycle.
