Can you support a BCB-regulated virtual asset service provider in São Paulo?

Yes, we build the technical infrastructure and AML/KYC controls commonly expected under Brazil's BCB crypto-asset oversight regime.

Do you have experience working with São Paulo-based businesses specifically?

Yes — we've delivered payment gateway & psp integration services, ai fraud detection & intelligent automation, blockchain & cryptocurrency development engagements for clients in São Paulo and across Brazil, building to the local regulatory and operational context from the start.

How long does a typical payment gateway & psp integration services engagement take for a São Paulo business?

A focused build typically runs 8-16 weeks; a full platform build-out runs 3-6 months. We scope and quote after an initial discovery call specific to your requirements.

Do you need to be based in São Paulo to work with us?

No — we work remotely with clients across every market we serve, coordinating on your team's schedule and tools, and can work alongside local counsel or partners in São Paulo as needed.

What's the first step to start a project in São Paulo?

A discovery call covering your specific requirements, timeline, and any regulatory or partner constraints already known — from there we scope a technical estimate, typically within 5 business days.

Can you support a São Paulo business that already has an in-house team?

Yes, we regularly work as an embedded pod alongside existing engineering teams, handing off documentation and architecture decisions rather than operating as a separate black box.

Do you provide ongoing support after launch for São Paulo clients?

Yes, post-launch retainers covering monitoring, incident response, and continued feature development are available for every engagement, not just larger platform builds.

How do you price a project for a São Paulo-based business?

Small, well-defined builds are typically fixed-price; larger, evolving platforms run on a monthly dedicated-pod model. We scope and quote after an initial discovery call, not before, so the estimate reflects your actual requirements rather than a generic rate card.

Overview

Building technology for São Paulo businesses

São Paulo is Brazil's financial capital and Latin America's largest fintech hub, home to the B3 stock exchange and a dense base of payment and banking innovation built around Brazil's instant-payment Pix system. Hurain Technologies builds payment, blockchain, and fraud-detection infrastructure for São Paulo-based fintechs operating under BCB oversight. Businesses based in São Paulo come to Hurain Technologies for Payment Gateway & PSP Integration Services, AI Fraud Detection & Intelligent Automation and Blockchain & Cryptocurrency Development, built by engineers who treat local context as a starting constraint rather than an afterthought.

São Paulo hosts the B3 stock exchange and the largest concentration of fintech unicorns and scale-ups in Latin America. Because São Paulo operates under Brazil's national regulatory framework, platforms built here need to satisfy the same expectations as anywhere else in the country: brazil's 2023 crypto-asset law gives the Banco Central do Brasil (BCB) direct authority to license and supervise virtual asset service providers, a significant shift from the prior unregulated environment.

São Paulo-based crypto businesses now operate under Brazil's 2023 crypto-asset law, giving the BCB direct oversight of virtual asset service providers. That trajectory is exactly why platforms built for São Paulo today need to be architected for tomorrow's volume, not just the traffic a launch-day demo needs to handle — retrofitting scale onto a system that wasn't designed for it is consistently more expensive and more disruptive than building for it from the outset.

We've found the São Paulo businesses that scale fastest are the ones that treated their initial platform build as infrastructure to grow on, not a minimum-viable launch to revisit later once problems surfaced.

We work with São Paulo businesses the same way we'd work with a client in any market we've operated in for years: reading the actual local regulatory texts, understanding the competitive landscape specific to the city, and making architectural trade-offs informed by that context rather than generic assumptions.

The Challenge

What businesses run into in São Paulo

Keeping pace with São Paulo's growth

Brazil's Pix instant-payment system has driven exceptional real-time transaction volume, raising the bar for fraud detection and settlement infrastructure.

Meeting Brazil's technical compliance expectations

Payment institutions and Pix-participating entities are supervised by the BCB under Brazil's instant payment system rules.

Scaling past engineering decisions inherited from a template built for a different market that don't quite fit local requirements

This is one of the most common reasons São Paulo businesses come to us after an initial build with another vendor — the system worked at launch, but wasn't designed for the volume and complexity that came with actual growth.

Finding engineers who understand São Paulo's specific market

A generic offshore team applies the same playbook everywhere. Getting local context — regulatory nuance, typical customer expectations, competitive landscape — right the first time avoids costly rework later.

How We Solve It

Engineering focus for São Paulo businesses

Payment Gateway & PSP Integration Services in São Paulo

Poor PSP routing and retry logic silently loses revenue on every failed or declined transaction.

AI Fraud Detection & Intelligent Automation in São Paulo

Static rule engines can't keep up with evolving fraud patterns, leading to rising chargeback and loss rates.

Blockchain & Cryptocurrency Development in São Paulo

Many blockchain builds start with insecure, unaudited contracts that fail third-party security review and block funding or listing.

Production-grade delivery for São Paulo teams

The same engineering discipline regardless of city size: formal test coverage, security review before launch, and monitoring from the first day of production traffic.

Industries

Sectors we support in São Paulo

Crypto & Web3 in São Paulo

Exchanges, token issuers, and Web3 platforms need production-grade blockchain engineering — not prototype code — to survive audits, scale to real transaction volume, and integrate cleanly with fiat rails. A common starting point: token, coin, and smart contract development.

Payments & PSPs in São Paulo

Payment service providers and platforms handling multi-rail, multi-currency transactions need orchestration, reconciliation, and fraud controls that scale across markets without manual overhead. A common starting point: payment orchestration and smart routing.

Enterprise SaaS & Platforms in São Paulo

Fast-growing SaaS platforms need to modernize architecture, expose secure partner APIs, and automate operations to keep shipping quickly as customer and data volume scales. A common starting point: monolith-to-microservices migration.

Real Estate & PropTech in São Paulo

Real estate platforms and PropTech operators are digitizing property transactions — from tokenized ownership and fractional investment to automated escrow and payment flows — and need engineering that can handle real money movement and regulatory scrutiny, not just listings software. A common starting point: tokenized property and fractional ownership platforms.

Cross-Border Remittance & Money Transfer in São Paulo

Remittance operators and money transfer platforms compete on speed, cost, and reliability across dozens of corridors simultaneously, and need payment orchestration, compliance automation, and fraud controls engineered for high transaction volume and thin margins. A common starting point: multi-corridor payout and payment rail integration.

Digital Banking & Neobanks in São Paulo

Neobanks and digital-first banking platforms have to ship product at software speed while meeting the same regulatory bar as incumbent banks, which means API-first core architecture, automated compliance, and fraud controls built in from day one rather than retrofitted. A common starting point: api-first core banking and ledger architecture.

Our Standard

What every São Paulo engagement includes

Architecture reviewed for local context

Data handling, access control, and compliance patterns designed against the regulatory reality São Paulo businesses actually operate under, not a generic template.

Built for real transaction volume

Load-tested against realistic usage patterns for a business operating in São Paulo, so scaling past launch doesn't require an architecture rewrite.

Security review before launch

Internal security review and, for platforms handling meaningful value or sensitive data, independent third-party audit coordination before go-live.

Documentation your team can use

Architecture decisions and operational runbooks handed off in a form your internal team or future hires can work from directly, not locked in one engineer's head.
