The business has been designed to provide development, training, coaching and social media support to brokers across the UK.
While it is a standalone business, No 6 will retain its link with TMG, which will remain its largest client.
The move will also see Corbett and Needham create their own protection brand under the TMG Direct network.
Jonathan Needham, business development director at TMG, said: “Following in-depth conversations with Scott and Martin, we all agreed the creation of No. 6 felt a natural progression for Dave and I, having supported individual brokers and mortgage and protection firms for many years, to do this under our own banner is very exciting.
“It is apparent that there are gaps across the industry in respect of support, guidance and direction from people who have bought and worn the t-shirt, many times, and talk in a language most brokers will ‘get’; No. 6’s objective is to plug that gap.
“Whether that support is around lead generation, building a social media presence, developing multiple income streams, increasing the number of clients who are being protected, recruitment, business growth and development or helping firms to understand what their ‘exit’ looks like, why they should have one and how best to realise it.
“We are not here to lift anyone’s leg either, we basically want to deliver proper, no nonsense support; that works.”
Martin Stewart, chief executive of TMG, added: “Jonny and Dave have added so much value to TMG in a really short space of time.
“Their approach to the industry is very refreshing, and their work ethic has really pushed our brokers to deliver in 2022 and beyond.
“We are delighted to continue our business relationship with Jonny and Dave under the banner of No. 6. We have maintained their services for recruitment on an exclusivity basis and their remit is to double our head count by the end of 2022 as we continue to push towards dominating our unique position in this mortgage market.”
