We design, buildand modernizefinancial systems.
Senior engineers and technology leaders for banks, fintechs and market infrastructure. We help you make the big technical decisions, then build alongside your team.
We’ve spent our careers inside the systems that can’t fail. Now we use that experience to help you decide what to build, and to build it with you.
Where we can help.
Six situations we’re often called in for. Start with the one that sounds like yours.
All servicesWho we work with.
Banks, market infrastructure and the companies that build for them.
Banks
Core systems that have to keep running while everything around them changes.
Payments
Real-time rails, new message standards and volumes that only go up.
Capital markets
Trading infrastructure where latency and correctness both matter.
Clearing & settlement
Post-trade infrastructure facing shorter cycles and tighter controls.
Fintech
Growing teams that need bank-grade architecture before scale exposes the gaps.
How working with us usually goes.
We start with what’s actually going on.
We look at your systems, talk to your people and learn what you can and can’t change. Then we agree on which decisions matter most right now.
We make the big calls together.
We get leadership and engineering in the same room and work through the trade-offs. You leave with clear priorities and the reasons behind them.
We build it with you, then hand it over.
We work inside your team until it’s live. Along the way your people get to know the system as well as we do, so you don’t need us to keep it running.

Advice from people who’ve built the real thing.
Before Molte, we built and ran systems at banks, exchanges, clearing houses and fintechs. That’s the experience we bring when we advise you, and when we write code. We’re based in Stockholm and work wherever our clients are.
- We work inside your team
