FinTech development at Pharos Production: payments processors, banking-core, lending, RegTech, digital-assets trading. Audit-first delivery with PCI-DSS, PSD2, SOC 2. 15+ regulated systems shipped since 2019.
Custom FinTech development gives you control over the regulatory model, unit economics and customer experience, while payments-as-a-service (Stripe Connect, Adyen for Platforms, Unit) ships in days but locks you into vendor pricing and rules. According to the 2024 a16z FinTech research, 63% of growth-stage FinTech founders eventually move at least one core flow off PaaS to capture margin.
| Factor | Custom FinTech build | Payments-as-a-service |
|---|---|---|
| Unit economics | Direct merchant or sponsor-bank rates; margin captured by you | Vendor markup of 1-3% + fixed fees; margin capped |
| Regulatory model | You hold (or partner with) the licensed entity; full compliance ownership | Vendor holds the license; you operate as a sub-merchant |
| Customization | Tailored flows for KYC, dispute handling, multi-currency, jurisdiction logic | Generic templates; limited workflow control |
| Data residency | Your VPC, your region, your retention rules | Vendor regions; subject to vendor data flow |
| Integrations | Native to your core banking, ledger, ERP, fraud and risk stack | Webhooks + vendor SDK; deep integration limited |
| Time to launch | 4-9 months for production-grade build with compliance review | Days for basic flows; weeks for custom rules |
| Cost (year 1) | $40,000-$400,000+ build cost amortized over volume | 0.3-3% of GMV in perpetuity |
| Lock-in risk | Open architecture; portable data; swap rails on contract | Vendor lock-in on rails, pricing and roadmap |
Our FinTech practice ships regulated production systems, not pilots. A dedicated FinTech engineering team, PCI-DSS-architected infrastructure, SOC 2 controls aligned with ISO 27001 and 15+ FinTech systems handling real money delivered since 2018 across payments, banking-core integrations, lending origination, RegTech and digital-asset rails. We work the full stack: PSD2 strong customer authentication, ISO 20022 messaging, FedNow, SEPA Instant and SWIFT integration patterns, PCI scope reduction through tokenisation, ledger-as-source-of-truth event sourcing, KYC and sanctions automation (Sumsub, Onfido, Chainalysis, TRM Labs) and fraud modeling that combines hard rules with sub-50ms ML scoring at checkout. We do not deploy money-movement code without a documented compliance program, sponsor-bank or licensed-entity sign-off and an external pen test. Every project ships with PCI scope diagrams, SOC 2 evidence pack and a 24/7 incident-response runbook. We routinely advise clients NOT to build payments in-house when a licensed PSP wins on cost, speed-to-market and compliance scope, and we say so before quoting. Below are selected projects from FinTech, banking and payments clients.
Pharos Production has partnered with Pleenk to build a secure, scalable payments platform for fast transactions, fraud prevention and seamless integration with digital products. The platform processes payment flows in real time while maintaining high levels of security, transparency and reliability for both businesses and end users. Built on cloud-native infrastructure and an event-driven architecture, Pleenk provides a strong foundation for modern digital payments.
Pharos Production partnered with Nextcheck to replace outdated, manual onboarding with a secure, automated KYC/AML platform. Built on AWS, Kubernetes, Istio, Elixir, RabbitMQ, PostgreSQL and NextJS, the platform provides real-time biometric and document verification, risk assessment and compliance reporting. Since 2019, Nextcheck has reduced onboarding time by 60%, cut manual labor by 70% and expanded to support thousands of checks at once. Today, it powers global banks, fintechs and crypto firms with a cloud-native, regulation-ready, growth-oriented compliance platform.
Pharos Production has partnered with Kimlic to develop a blockchain-based Know Your Customer (KYC) and digital identity platform. This platform ensures that user verification is secure, reusable and privacy-preserving across Web3 and fintech ecosystems. Users can verify their identity once and then securely share proof with multiple services without exposing sensitive personal information. Built on cloud-native infrastructure and equipped with real-time data pipelines, Kimlic provides compliant identity verification at scale while allowing users to retain control over their data.

The Pharos Compliance-First Pipeline is our four-step delivery cycle for production FinTech software: Compliance Discovery, Threat and Fraud Modeling, Regulated Build and Audit and Production Hardening.
maps the regulatory perimeter before code: PCI-DSS scope, PSD2 SCA obligations, KYC/AML and sanctions-screening requirements, data-residency rules under GDPR or CCPA, and licensing posture (sponsor bank, EMI, money transmitter, MiCA)
enumerates attack surfaces against the OWASP Top 10 and the financial-services taxonomy: card fraud, account takeover, synthetic identity, authorized push-payment fraud, internal abuse, sanctions evasion
ships the platform under PCI-DSS architectural rules with tokenisation to minimise cardholder-data scope, ledger-as-source-of-truth event sourcing, KYC and sanctions integrations (Sumsub, Onfido, Chainalysis, TRM Labs) and SOC 2 controls baked in from day one
coordinates external penetration test, SOC 2 readiness review with the client auditor, multi-region failover drill and 24/7 incident-response runbook tied to FFIEC examination guidance
The pipeline is named because moving real money is irreversible - we re-enter Compliance Discovery and Hardening on every new rail, jurisdiction or sponsor-bank partner across the engagement lifetime.
Pharos Verified Delivery applied to 70+ production applications since 2013
Anonymized before/after snapshots from production projects. Metrics measured against client-reported pre-engagement baselines.
Manual reconciliation of 12,000 daily transactions across 4 payment providers. 3 full-time analysts. 18-hour delay between transaction and matched status.
Automated reconciliation in under 2 minutes. Analysts reassigned to exceptions review. Zero unreconciled balances across 12 months in production.
We built a provider-agnostic reconciliation engine with a shared ledger format, deterministic matching rules and an exceptions queue for the 0.3% of transactions that need human review. The ledger became the system of record for all four providers.
Manual KYC review averaged 48 hours per applicant. 22% drop-off during the wait. Compliance team backed up.
Automated KYC pipeline with Sumsub integration, sanctions screening and risk-tier routing. 92% of applicants approved in under 5 minutes. Drop-off rate down to 7%. Compliance team handles only edge cases.
Low-risk applicants auto-approve on the spot; medium-risk go to a 15-minute enhanced review flow; high-risk and PEP matches hit the compliance queue. Every decision is auditable with a full document and rule trail for regulators.
Rules-based fraud detection caught 41% of fraud attempts. Each rule update required 2-3 weeks of engineering work. Fraud loss rate 0.8%.
Custom ML model trained on transaction patterns. Caught 87% of fraud attempts with 0.4% false positive rate. Continuous retraining monthly. Fraud loss rate dropped to 0.12%.
Features derived from velocity, graph relationships and device fingerprints; a gradient boosting model serves predictions in sub-50ms at checkout. Hard rules still handle sanction lists and hard blocks; the ML tier handles grey-area scoring.

We decline roughly 30% of RFPs we receive. Forcing a bad fit costs both sides 3-6 months and damages outcomes. Here is how we think about scope:
Not every FinTech idea needs custom development. We have recommended Stripe over custom payment processors, Plaid over custom bank integrations and Persona over custom KYC. Custom FinTech is the right call when you need unique workflows, regulatory configurations or competitive differentiation that packaged products cannot provide.

No. Pharos Production builds the software; the client (or a sponsor bank partner) holds the regulatory license. We are happy to integrate with your sponsor bank or BaaS provider (Synapse, Treasury Prime, Increase, Column, Bond) and design the compliance program with your legal counsel, but we do not hold money transmitter, banking or broker-dealer licenses ourselves.
A production payments MVP typically takes 4-6 months: 2-4 weeks discovery and compliance review, 8-12 weeks build (KYC, ledger, payment rails, dispute handling, reporting), 4-8 weeks integration testing with your sponsor bank or processor and regulator-aware UAT. Pharos has shipped 15+ FinTech systems handling real money since 2018.
Pharos infrastructure is PCI DSS architected, SOC 2 controls in place and aligned with ISO 27001, with GDPR processing roles documented. We minimize PCI scope using tokenization (Stripe, Spreedly) wherever possible and design data flows so cardholder data never enters client logs or backups. We document data flow diagrams, retention rules and incident response plans for your auditor. See our State of FinTech Compliance Cost 2026 for detailed cost breakdown across regulatory frameworks.
Use packaged services when they fit your model: Stripe for card-present and SaaS billing, Plaid for bank linking, Persona/Sumsub for KYC. Build custom when you need: direct sponsor-bank pricing at scale, jurisdictional compliance (PSD2, FFIEC, MiCA), proprietary risk models, multi-rail orchestration (cards + ACH + crypto + wire) or unit economics that vendor markups make impossible.
Yes. We integrate with FIS, Fiserv, Jack Henry, nCino, Mambu and modern core banking platforms (Thought Machine, 10x Banking) via SOAP, REST and event-driven middleware.
We build the abstraction layer so your product code stays decoupled from the core, which means your core upgrade does not break your customer-facing app.
For crypto fiat rails we integrate KYC/AML providers (Sumsub, Onfido, Persona, Jumio) for identity verification, Chainalysis or TRM Labs for blockchain analytics, and design the off-ramp/on-ramp flows around the client’s licensed sponsor or money transmitter. Compliance program design is the client’s responsibility; we build the software to enforce it.
Backend: Elixir/Phoenix and Java/Spring for high-throughput payment paths; Node.js or Python for orchestration. Storage: PostgreSQL for ledger, Kafka for event sourcing, ClickHouse for analytics.
Cloud: AWS with VPC isolation, KMS for key management, CloudHSM for PCI-scoped operations. Frontend: React/Next.js with strict design tokens. Observability: Datadog or Grafana stack with PII redaction.
We decline when: payment processing could be solved by a Stripe/Adyen integration alone; lending products lack legal counsel on usury and disclosure rules; crypto products lack jurisdictional analysis from qualified counsel; or the team has no plan to operate the compliance program post-launch. Forcing a regulated build without these foundations costs everyone time and reputation.
Jurisdiction is a product decision, not a legal afterthought. Common patterns: EU passporting via Lithuania or Ireland for EMI/PI licenses; UK FCA for retail-facing payments and lending; Singapore MAS for APAC reach with PSP/MPI license; US state-by-state MSB plus federal layer for crypto.
We start by mapping your customer geography, transaction profile and capital plan, then work with your counsel to pick a primary plus expansion path. Wrong jurisdiction picks add 6-12 months to timeline and force re-architecture of KYC, sanctions screening and reporting flows.
A ledger is append-only, immutable and timestamped. A relational ledger built on PostgreSQL or a purpose-built event store gives you reproducible balance reconstruction at any point in time, audit trails that cannot be silently mutated and direct alignment with PCAOB and SOC 2 audit evidence requirements.
We use double-entry semantics with explicit debit and credit legs, idempotency keys on every posting and async projection into denormalized read models. This pattern survives regulator review better than a mutable balances table that lost write history.
