Portx secures £1.8m for AI-driven portfolio analytics platform

Fundamental hedge fund managers access advanced decision-making tools through Portx Limited, a London-based software development firm. This AI-driven platform provides portfolio construction and analytics, specifically targeting institutional front-office teams who manage crypto and other asset classes. By offering both a user interface and a high-performance API, the system allows discretionary investors to back-test strategies without requiring quantitative expertise.

The £1.8m raised in this funding round follows a previous £635k injection completed in 2025 and values the business at an estimated £6.6m. Founded in 2021, the startup focuses on helping Long Short equity managers enhance idiosyncratic alpha and manage factor exposures.

Financial records for the year ending 30 September 2025 show the company employed one person at that time, though more recent data from LinkedIn indicates the headcount has since grown to seven staff members. The team partners with global risk data providers to integrate its proprietary optimization technology into existing workflows. The most recent allotment of shares and filing for this investment occurred in August 2026.
