Illuminate, created by Nucleus, will act as a "knowledge centre" to support the firm's live events.
It hosts a range of interactive learning materials from experts, including blogs, white papers and videos covering practice development, technical, industry, compliance and marketing.
The new service is designed to "help build and share ideas and thinking in areas that are vital to the successful development of advisers' practices".
The company said it aspires to "offer inspiring, educational and in-depth practical workshops from leading experts to help advisers further develop their businesses".

Barry Neilson, business development director at Nucleus, said: "At Nucleus, we believe one of our biggest competitive advantages is the quality of our audience. "Over the years, we've managed to cultivate a user base of some of the most client-focused and progressive firms across the financial planning profession.
"One characteristic many of our users share is the desire to keep improving their businesses and client propositions and, in a small way, Nucleus has tried to encourage the sharing of best practice across our audience via our regular practice management sessions.
"To evolve this support further, we are now delighted to launch Illuminate to help build and share knowledge in areas that are critical to the successful development of adviser businesses."
Mr Neilson said: "This isn't all about Nucleus though. The intention is to host a wide range of shared learning materials from industry experts and we currently have content from over 30 recognised industry commentators.
"Illuminate will also to act as a portal to other great content available elsewhere and as curator, we're looking to encourage awareness of the key issues that will allow our users to keep on improving their businesses and client propositions."
