The H4 team is defined by its unusual mix of people – as diverse in expertise as it is in background and outlook. We’re a motley crew of investment bankers, technologists, corporate lawyers, product designers and talented people from many other walks of life.

Without H4, it's unlikely our paths would have crossed. But magic happens when you bring together a team like ours.

And first and foremost, we're a team. Because it’s only by blending the industry knowledge of seasoned finance professionals and lawyers with the ingenuity and perspective of expert designers and engineers, that we can build a technology capable of transforming our industry for the better.
