We didn't buy our core. We built it from scratch.
System design for the AI age
AI-first, in production
Few engineers and many agents running everything
AI in the product
fraud/risk models, document and KYC verification, customer support automation
AI in how we build
agents author, agents review, humans approve. 100% of merged code is AI-assisted
AI in how we operate
agents build dashboards, triage alerts, draft postmortems etc. - full process automation
Nova Platform AI
99.99% uptime on core payments
Quality is an engineering discipline here, not a QA ticket
Empowering our engineers to ship faster without ever compromising on reliability

Fraud prevention is a product, not a policy.
Models, rules and agents we built ourselves. Every transaction is scored the moment it arrives; every control is measured by its cost.
Predictive models
Device, behavior, network and history. Hundreds of attributes scored in real time, with continuous retraining.
Rules platform
The precision and cost of every control in a single view, tuned in minutes. No deploy and no engineer needed.
Operational agents
Agents tune detection, work the dispute queue and gather evidence. The loop closes.
Detect
Models + anomaly
alerts
Prevent
Rules platform,
the intervention ladder
Recover
Agents working on
dispute resolution
Retrain

What it's like to ship here
AI is part of how we work every day, not a side experiment, and it lets a small team move like a much bigger one. You don't need three layers of approval to fix something you know is wrong.
Matheus Paes,Senior Software Engineer
We test a lot, and our release process is fast and safe. We can revert any issue quickly, so we feel confident shipping any change, any time, with no downtime.
Vinicius Nordi,Tech Lead
Our mobile team works more like a payments platform. Every feature sits behind a remote feature flag, so we can launch, fine-tune and expand it in real time, without waiting on an app store release.
Gleidson Ramos,Senior Mobile Engineer
