NORTH REWIND

We build software, games, AI agents, payment platforms and technology strategy.

Senior expertise from a former fintech CTO and crypto tax founder. 20 years of programming, including real-time systems that process live transactions under high load, where downtime is not an option.

What we do

Six areas of expertise, one senior team. From strategy and funding to production code.

Software & product development

Robust products built and run for the long haul, from first sprint to production. Do you need custom software, senior hands to build a new SaaS, or a safe path to modernize a legacy system? We have done all three.

  • Functional programming
  • Web & mobile
  • Message queues & event-driven systems
  • OLTP & OLAP databases
  • Container orchestration
  • Cloud infrastructure
  • Agile development

AI & automation

AI that takes real work off your team. Want to know where AI pays off in your business, automate a multi-step workflow with agents, or put your own documents to work with an LLM? We take you from idea to production.

  • LLMs
  • RAG
  • AI agents & agentic workflows
  • AI-assisted development
  • Data engineering & analytics

Fintech, compliance & security

Systems that move money and stand up to auditors, built by people who have run them. Building a payment flow, facing new regulation, or need a second pair of eyes on code and security before launch?

  • Payment platforms
  • Real-time transactions
  • Regtech & compliance
  • Crypto tax
  • Security review

Strategy & leadership

Clear technology decisions and the leadership to carry them out. Need a CTO without hiring one full-time, an architecture that lasts, or a team that ships? Or a talk or workshop for your organisation?

  • IT strategy & architecture
  • Wardley Mapping
  • SWOT analysis
  • Fractional CTO
  • Team building
  • Workshops & speaking

Startups & capital

From idea to an investable company, with founders who have raised capital. Not sure which tech stack to bet on, how to ship an MVP fast, or whether you are ready for investors? We also do technical due diligence for investors.

  • Tech stack selection
  • MVPs
  • Investment readiness
  • Technical due diligence

Games

Original games and interactive worlds, designed and developed in-house. Have a game idea, need a playable prototype, or want to make your product more engaging? We can help you build it.

  • Game design
  • Prototyping
  • Interactive experiences

Our experience

Proven where it counts: in production, with critical systems that have real users and high traffic.

We have taken a fintech platform from its first line of code to market leadership, founded a crypto tax company trusted by banks and authorities, and built enterprise software used every day. We have raised capital ourselves and sat on the board. When you work with North Rewind, you get people who have shipped, scaled and been accountable for the result.
