FinTech products with the control layer regulators expect
AML-grade oversight of political ad spend, a crypto intelligence platform rebuilt with an AI layer, financial-crime investigation software for a national authority: we build FinTech where every dollar has a trail and every integration has a fallback.

This is for you if you move money, data or risk
Integrations are the product
Payment rails, card issuers, exchanges and banks — with retries, idempotency and reconciliation.
AI on financial data
Intelligence and automation with evaluation, explainability and cost control.
You need a team that has done it
Three public FinTech case studies, from scratch and from takeover.
What FinTech gets from us. Controls as engineering
How we work in FinTech
Compliance engineering
Virtual cards only the right person can activate, AML checks, audit trails, roles — built from scratch for political ad spend oversight.
Reliable integrations
Idempotent payment flows, reconciliation jobs and observability for every third-party call.
AI intelligence layers
RAG and semantic search over market and transaction data, tested across several LLMs in production.
Where FinTech breaks
Three failure modes we design against.
The double charge
Idempotency keys, retries with backoff and reconciliation jobs are not optional in a payment flow.
The audit you cannot answer
Who did what, when, with which data — logged immutably from day one.
The integration with no fallback
Every external dependency gets a timeout, a circuit breaker and a plan for when it is down.
AML-grade oversight, built from scratch
In this U.S. political ad spend platform, campaign funds move through virtual cards that only the assigned agency employee can activate.
We designed and built the control layer from the frontend to infrastructure for a client under NDA.
The platform controls who can activate a virtual card and how campaign funds reach advertisers.
Pirxey provides you the full package - you can ask for data experts, you can ask for AI experts, you can ask for frontend experts, and you have everything. The communication was really great - more than that, it was amazing.
What you get. Six ways we build FinTech
Compliance & control layers
KYC, AML, roles, audit trails, virtual card controls.
Payment & banking integrations
Rails, issuers, exchanges, banks — idempotent and reconciled.
AI intelligence
Market and transaction intelligence with semantic search and evaluation.
Secure infrastructure
Encryption, secrets management, observability, residency.
Takeover & audit
A fast-built platform assessed and hardened before real money flows.
Crypto & blockchain
Smart contracts and exchange integrations with security review.
How we work
Every dollar has a trail
We set deadlines once the design is final, counted in working days, not as dates promised in a sales call. You hear about a problem from us, with options, while there is still time to choose.

How it works. From a regulated idea to a product in production
Scoping call
What you want to achieve, by when, with what budget. We say on the call whether we are the right team, and what the smallest useful first step is.
Workshop & plan
A short workshop with your stakeholders: outcome, hard and soft deadlines, integrations, risks. You get a written scope, a price range and the split between what AI accelerates and what needs a senior engineer.
Build in increments
We build in deployable increments with code review and automated tests. You get a status daily at first, then weekly once trust is there. Scope lives in Linear; conversations happen in Slack.
Launch & grow
Monitoring, documentation and runbooks handed over, or a squad that stays. Either way the product can be operated without us.

What clients say
"Pirxey gave us the full package - frontend, backend, AI, and data - all under one roof, which meant we never had to coordinate multiple vendors. They thought like product owners, not contractors."
"What stayed with me was the communication. Fast, clear, and always with something concrete - a proposal, an update, a solution. We never had to wonder what was happening."
"Their ability to quickly deliver high-quality solutions while maintaining transparency in communication is rare."
"When you propose something to them, they don't simply say yes - they come back with a pro and con. You're not getting a classic developer who simply does and then you have to fix the thinking yourself. If I had another AI idea and wanted to pursue it, I would just use Pirxey."
"Well… didn't know what to expect but honestly, now I'm learning much from you guys. Had no idea an external tech partner can be so pro and organized."
"Their ability to quickly deliver high-quality solutions while maintaining transparency in communication is rare."
The people who build money software
In FinTech the interesting code is the boring code: idempotency, reconciliation, audit logs. We write it first, not last.

Questions FinTech teams ask us
- Our public case studies cover political ad spend controls for an unnamed client, investigation software for Matic, and Signal Mesh’s crypto intelligence platform. These describe delivered systems, not a blanket regulatory certification.
- Scoped in discovery with your compliance owner; controls are modelled in the domain, logged immutably and tested, with evidence for auditors.
- Yes, with idempotent flows, retries, reconciliation and monitoring for every provider call.
- Yes. We start with an audit of code, infrastructure and access controls, then harden before adding features — as with Signal Mesh.
- Where it earns its place: intelligence, search and automation with evaluation and cost control; never as an unreviewed decision maker on money movement.
- We are a remote team based in Poland, with 130+ engineers at the company. We agree working-hour overlap with your team at kick-off.
- We start with your payment flows and the controls they need. Discovery with your product and compliance owners defines the scope and price range.
