About

Avenir Technology | Markets Technology

Essential software infrastructure. Expertly Built.

Avenir Technology, based in New Zealand and London, builds and exports world-class software for stock exchanges, clearing houses, registries, and private markets. 

Decisions to change or implement core market infrastructure are rare, often once or twice in an exchange’s lifetime. We take that seriously. From day one, we work alongside you with hands-on support from design through integration and beyond, so you can grow your market with confidence.

Our team brings together exchange experts, technologists, and market specialists, who deliver the depth, experience, and capability needed to build and run the infrastructure your market depends on.

Born from Experience. Built for the Future.

Avenir Technology was founded by a team of financial market veterans who had seen firsthand how legacy systems were slowing the industry down. Frustrated by outdated, inflexible infrastructure, they set out to build something better combining deep domain expertise with a passion for creating secure, elegant, and efficient solutions for modern markets.


Today, Avenir powers critical systems across multiple continents, including regulated stock exchanges, private markets, registrars, and emerging financial centers.

The team behind the vision

What sets us apart is not just our technology. It is our team made up of global exchange experts who bring deep experience and a passion to drive real change. It is our Kiwi attitude, our agility, and our responsiveness. It is our ability to deliver robust infrastructure without the long timelines or inflated costs that often come with legacy systems. We listen. We move fast. We bring domain expertise, not just software.

What guides us

Over the past decade, we’ve grown organically, expanding our global footprint and scaling our team by building strong, reliable technology. We believe the right technology, built the right way, can transform markets for the better. We’re building systems that power markets, and we’re doing it together.

At Avenir, we don’t just write code or follow specs. We solve real problems for capital markets, and we back each other to do it well. We know the stakes are high, but we keep things grounded, supportive, and even fun.

We take our work seriously, not ourselves.

What keeps us moving in the same direction are our five shared values. These are not just words; they drive how we show up every day at work and with our clients.

Quality – We hold ourselves to high standards in everything we do, from code to communication. 

Respect – We listen, support each other, and value diverse perspectives. 

Collaboration – We work together with our clients and team to solve complex problems.

Responsibility – We take ownership. We deliver on our promises. 

Passion – We care about the details and the impact of our work. 

Here for you

Avenir is quietly powering the future of capital markets from New Zealand to the world, and we continue to do what we love, with people who care deeply about building better markets and even better technology, together.
