Over the last decade, the equity financing markets have undergone drastic changes as a result of both regulatory and business constraints. Clear convictions about the future of this market led Cellyant founders to consider developing Cellyant Convergence, the first liquid, open and regulated fund totally dedicated to security financing strategies.


Cellyant’s ambition is backed to a proven ability to combine fundamental tax / regulatory analysis with derivatives trading expertise and unique sensitivity to market and operational risks. Such an expertise allows Cellyant to unveil and implement arbitrages through an efficient and adaptable process, capturing all the components of a trade from inception to settlement.
