We exist because every ecosystem needs the capability to stop rebuilding.
Founded in London in 2016 by Ralph Bragg and Barry O'Donohoe — tasked with designing and delivering the world's first Trust Framework for Open Banking in the UK. Today, led by Charlotte Crosswell OBE as Executive Chair. Operating ecosystem infrastructure across Brazil, Australia, UAE, New Zealand, and the United Kingdom. One mission: build once, expand everywhere.
Purpose-built for ecosystems that grow
We design, build, and operate the ecosystem control plane — the governed infrastructure layer that manages who can participate, what they can access, and whether they can be trusted. Our clients include central banks, scheme operators, and globally systemically important financial institutions across five countries.
