Nucleus Group

Adviser platform and wealth management software

Overview

Nucleus Group provides investment platforms and wealth technology for UK financial advisers and their clients. Its core product is a wrap platform that consolidates client assets (SIPPs, ISAs, GIAs) into a single online account, with adviser tools, model portfolios, bulk switching, rebalancing, and reporting, plus a client portal called Nucleus Go. The group differentiates itself by focusing on adviser efficiency and by not selling funds or giving advice, instead integrating multiple platforms from acquisitions to offer a unified, adviser-centric solution. Its goal is to help advisory firms run their business more efficiently and scale assets under administration through a comprehensive wealth-tech platform.
