Paul Murphy

CEO | Founder


Paul was born in Argentina. He grew up in France, Italy, and America. He’s been lucky enough to work in New York, London, Buenos Aires, Zug, and a few other places. He used to write a lot of code. Now he’s kind of rusty. He does whatever needs doing, whether or not it’s fun.

In his spare time Paul participates in several activities that make his vegetarian friends unhappy. He firmly believes that the answer to most questions can be found in musical and opera scores.


Neil Zumwalde

CTO | Founder


Neil was born in a state of sanity called Minnesota. His parents taught him never to trust fast-talking people from the coasts, which has served him well. Neil moved to Austin because he was tired of being cold.

In his spare time he writes music for a pretty famous band, performs with several less famous bands, and has more ideas per hour than normal people have in a lifetime

Momin Ahmad



Momin is the engineering group’s secret weapon. He pretends to know very little and then solves problems in ways that surprise his older team members.  Thanks to his years in the music industry, Momin is both unflappable and rarely surprised by the foibles of human nature.

A UT graduate with a focus in philosophy, Momin somehow managed to pick up all sorts of useful skills between gigs and basketball games.

Robert Cohen



Robert is a natural researcher and writer. He has worked for top early-stage VC firms Social Starts and Joyance, Manhattan Venture Partners and Keiretsu Forum. Robert’s analyses have appeared in leading technology magazines throughout the world.

Anyone who thinks philosophy degrees are useless should spend a day working with Robert. His thinking is all Hegel, with healthy doses of Plato, Kierkegaard and Nietzsche.  It’s unclear how anyone can handle the implications of crypto without the help of this pantheon.

Serge Ugarte



Serge is both a rare bird and an odd duck.
Serge started his career as a management consultant in the Fintech space. Unfortunately the Global Management Consultant’s Union, a very secretive organization, kicked him out for being too smart, too hands-on, and too practical.
In 1998 Serge noticed that the Internet was really starting to get some traction, so he went to work for Cisco. He helped them navigate the post-crash world by selling hardware to companies that knew how to make money. Hands-on and practical turned out to be useful after all. In early 2010 Serge was recruited to lead Global Business Development at FICO. For a variety of reasons he also worked very closely with FICO’s Corporate Development division. His time there proved once again that competence is almost always rewarded with more work.
Today, Serge lives and breathes crypto, but keeps it  quiet from friends and family who wouldn’t understand how he could have strayed so far from a respectable career. He did tell his wife, however, when he realized that someone he trusts needed to be able to recover his hardware wallet.

" Cryptocurrencies are changing the world. They are the foundation of the next financial system. No financial system can exist without credit, and credit can't be extended without credit data. We want to help change the world, so we are providing this data. "
