Castleton Tower

Castleton Tower is a boutique consulting firm that works exclusively with investment management firms, among them RIAs, family offices, institutional investors, hedge funds and asset managers. Its remit is data: building and integrating data solutions and modernising data infrastructure so that allocators can make fuller use of the information they hold. The firm was founded by executives with experience building and leading quantitative research, data science and technology teams at top-tier hedge funds and asset managers.

The technical work spans data lakehouses, data integration and infrastructure modernisation, alongside AI-ready data foundations. Three service lines are offered. Data Integration Services connects disparate sources into a centralised data hub for investment management firms. Advanced Data Lakehouse Solutions builds and integrates lakehouse architectures intended to modernise existing infrastructure and prepare it for AI use. Bespoke Application Development covers custom software, including advanced reporting, risk management tools and portfolio optimisation solutions.

The firm operates as a lean team of senior practitioners who carry out the work themselves, combining strategic advice with hands-on technical implementation. Its stated verticals are investment management, asset allocation, wealth management, family offices, institutional investing, hedge funds and asset management.
