Trakx
Early-stage consulting & feasibility
Trakx is a Paris-based crypto-index trading platform, now AMF-registered and backed by ConsenSys. I provided early-stage technical consulting when the founders were validating the concept: feasibility analysis, architecture guidance for building a compliant crypto-index product, and strategic input on how to structure tradable baskets of digital assets. Trakx went on to join the ConsenSys Tachyon accelerator, obtain VASP registration from the French AMF, and grow into one of Europe’s leading crypto index providers with more than twenty thematic indices. The engagement was short but formative, the kind of early technical validation that gives a founding team confidence to build.
