Four ways we work with you

Strategy and engineering sit in the same team, so what we recommend is what we can build and run.

AI product strategy

Find the use cases that pay back. We run discovery with your users and your data, size the opportunity, and write a roadmap your team can execute.

  • Opportunity mapping
  • Build or buy decisions
  • Roadmaps and success metrics

AI-native engineering

Agents, LLM features and retrieval built into your product, with evaluation, guardrails and cost control from the first sprint.

  • Claude and other LLM APIs
  • Agents and tool use
  • Evals and observability

Modernisation with AI

Move legacy systems to a modern stack without stopping the business. AI agents help us read, test and migrate code, and people approve every change.

  • Low-code to custom stack
  • Java and monolith migration
  • Automated test coverage

Fintech and capital markets

Platforms for trading, clearing and portfolio management, designed around exchange rules and regulation from day one.

  • Euronext Optiq · FIX 5.0
  • MiFID II · EMIR
  • B3 options

Selected work

Products we have designed, built and put in front of real users.

OptFlow · SaaS for B3 options traders

From a low-code MVP to a production fintech SaaS

We own product, architecture and go-to-market. The stack moved to React and Supabase, with broker-statement imports and FIFO reconciliation, real-time market data, role-based access, and Stripe billing with card, Pix and trials. AI agents are part of the daily engineering workflow.

How an engagement runs

Each stage ends with something you can decide on. You can stop after any of them and keep what was built.

  1. Discover

    2 weeks

    Interviews, a data review and a clear problem statement. You get a ranked list of AI opportunities and their expected value.

  2. Prove

    4 to 6 weeks

    A working proof of concept on your real data, with evaluation results, so the go or no-go decision rests on evidence.

  3. Build

    3 to 6 months

    Production engineering in short cycles: architecture, security, integrations and a release every two weeks.

  4. Run

    Ongoing

    Monitoring, model and prompt evaluation, cost tracking, and a handover your own team can own.
