Mission Statement

CompatibL is a software vendor specializing in risk, limits, and regulatory capital. We provide a unique blend of quantitative and engineering expertise combined with an award-winning risk platform. Our customers are some of the most respected firms in the financial industry including four major derivatives dealers, 3 supranationals, over 25 central banks, and 3 major financial technology vendors.

CompatibL started operations in 2003 with a project to implement a real time limit management application for a major US bank. The system went live in the beginning of 2004 in New York, London, and Tokyo, and remains in production today. Over its 17 year history, CompatibL remained independent and free of pressures that come with venture capital and outside shareholders. We only answer to our customers, and nobody else.

Today, CompatibL employs over 300 people whose only focus is trading and risk management. Unlike some of our competitors, we do not do social apps, video games, websites, or logistics. We do one thing only, and do it well.


CompatibL is a leading award-winning provider of custom software development services, market and credit risk solutions and model validation consultancy for the financial industry.

CompatibL was founded in 2003 by Alexander Sokol, winner of the Risk Quant of the Year Award and a seasoned technology executive who, prior to founding CompatibL, was founder and CTO of Numerix. Alexander continues to serve today as CompatibL’s Executive Chairman.

It is an old adage in the quant community that most quants can’t code, and most engineers can’t do math. From day one, CompatibL’s goal was to be the exception to this rule. We hire and train quants who also know a lot about software engineering, and we hire and train software engineers who have in-depth knowledge of math and quant models. Combining quant and engineering expertise in one team is what makes CompatibL so effective in developing software for the financial industry.

When other vendors build trading and risk solutions, more often than not the models and the application are developed separately and then fitted together. At CompatibL, we design our models from the ground up so that they work well within the application, and design the application so that it works well with the models.
