What Lexifi does
LexiFi (LexiFi SAS) is a Paris-headquartered, privately held software company founded in 2000 that builds specialized infrastructure for the pricing, lifecycle management, and reporting of derivatives and structured products. The firm operates from offices in Paris, Singapore, and New York, serving asset managers, private banks, brokerage firms, product issuers, and financial technology providers across Europe, North America, and APAC.
The company's technology is built on MLFi (Modeling Language for Finance), a proprietary formal language for describing financial contracts from inception to maturity, implemented on a forked version of the OCaml programming language that LexiFi has extended with type reflection. Two product lines sit on top of this stack: LexiFi Apropos, an integrated end-user application covering product definition, booking, pricing, risk, lifecycle event processing, and document generation; and Instrument Box, an embeddable/API-based component that exposes the same capabilities to technology partners. Notable technical components include Monte Carlo pricing with importance sampling, a Smart Adjusters variance-minimization method, real-time code generation that automatically produces user interfaces from MLFi contract definitions, and an LLM-based PDF Importer that parses exotic term sheets. The platform is also embedded inside third-party systems including Bloomberg's Derivatives Library and SimCorp's XpressInstruments module.
LexiFi monetizes through three streams: enterprise subscription licensing for Apropos (annual billing, cloud or on-premise), Instrument Box licensing and OEM royalties to technology partners, and professional services covering implementation, integration, and ongoing maintenance. Customer evidence is concentrated in tier-one European and global financial institutions (e.g., Bloomberg, SimCorp, Natixis, Lombard Odier, Deutsche Bank Belgium, Banque de Luxembourg, Arkéa Asset Management), and the firm has historically operated as a self-funded, founder-led specialist rather than a venture-backed scale-up, with no disclosed funding rounds and reported headcount in the 11–50 range.
