Xplain

What Xplain does

Xplain (operated by Solum Financial Limited, a private company incorporated in England and Wales, registered number 9050223) is a UK-based derivatives workflow software provider serving three financial services personas: corporate treasurers, fund administrators, and auditors. The platform addresses fragmented, spreadsheet-based derivatives processes by centralizing pricing, validation, and aggregation across a single engine with a built-in calculation layer using market practice methodology, plus an API that connects to existing TMS, ERP and execution systems without requiring replacement. The product suite is delivered as three persona-specific brands: Prisma for corporate treasurers (exposure aggregation, hedge monitoring, stress-testing and scenario analysis, board-ready reporting); Lumina for fund administrators (independent valuation, configurable break tests, data cleansing workflows, and NAV-ready outputs at multi-client scale); and Aurea for auditors (portfolio-wide break tests and standardized audit evidence beyond sample-based testing). The company monetizes through an enterprise SaaS subscription model sold via direct, consultation-led sales to mid-to-large financial institutions, supported by content-driven demand generation (insights, webinars, white papers). ISO/IEC 27001 certification is held at the parent entity level, and the firm operates with a very small team (approximately 5 employees per firmographic data), with no disclosed external funding or revenue figures.
