About us
Our team benefits from over 30-year experience in the world of financial markets (banks and hedge funds) spanning fields from quantitative analysis and research to risk management to software development.
Jean-Michel Fayolle, our founder, witnessed first-hand the gap in financial software solutions available to users of derivatives transactions with modest portfolio sizes when it comes to valuations and risk management, particularly valuation adjustments i.e. xVAs.
Indeed, software solutions are often sized to meet the computational demands of large, bank-sized portfolios with hundreds of thousands of transactions (thus requiring rather heavy infrastructures), while some alternatives seem to lack (some of) the analytics essential when dealing with derivatives -such as xVAs.
Our vision was therefore to provide those “left-out” institutions (such as corporates) with a complete range of market-standard analytics that is both:
easy to use (i.e. with an adequate user-friendly interface); and
easy to run (i.e. installed locally on a user’s machine and fast enough to ensure results are available within “seconds”).
The result is a range of analytics born out of decades of experience in modeling and efficient (fast) implementation, running on a simple PC or laptop, accompanied by an interface hosted within Excel© and developed with users in mind; a system that makes complicated tasks accessible via single, “simple”, buttons.
Our “sister” company, Quantaix, provides consulting and advisory services in the field of financial markets quantitative analysis and risk management.

Jean-Michel Fayolle’s bio
Jean-Michel has a (relatively long) history in the financial sector, in roles always linked to quantitative, risk or software-related matters.
His academic background is in mathematics, engineering (computer science) and probabilities & statistics.
Initially a quantitative analyst at SocGen in the early 90's, he joined former colleagues who founded Commerz Financial Products to head their Research Department in '94.
He then moved to AIG Financial Products (Banque AIG) in '97, quickly moving to London to head the New Products Group, position that he left in 2004 to pursue other interests. He returned to AIG early '07 in a Risk capacity, becoming the Banque's CRO post AIG's '08 debacle and Fed take-over.
Early 2011, he joined Aspect Capital, a systematic trend-following hedge fund, as CRO. In 2015, returning to France, he co-started ICA (now OpenSee) to develop a cloud-based xVA engine.
In 2020, he founded Quantaix, a quantitative advisory boutique. Initially developed for consulting purposes, both internal and with its partners, QxCell was transformed into a commercial product and launched by QxSolutions late 2022.
