Wrap platform Ascentric and institutional arm IFDL grew combined total assets by 20% over the first six months of the year to £6.2bn.
Net new business was up 39% compared with the same period last year to reach £813m, representing its strongest ever first half performance after two consecutive quarters of record net inflows.
Around 9,000 new customers were added to the platforms in the first half of 2013, meaning that the number of total customers rose 35% to reach 50,073.
More than 350 new adviser firms signed up to the IFDL and Ascentric platforms during the first half of the year.
Ascentric and IFDL managing director Hugo Thorman (pictured) said, "We have enjoyed a fantastic first half to the year driven by two consecutive quarters of record net new business. The rate of adoption in terms of net new inflows and sign ups has exceeded our expectations and shows the degree to which advisers are willing to embrace transparent wrap platforms in a post-RDR world.
"Demand for platform functionality continues to grow and we will look to meet those needs by rolling out a series of technology developments over the next year that I hope will enable us to deepen the relationships we have with our clients and help us achieve yet further milestones."
IFDL announced it was putting its direct-to-consumer (D2C) business Fundsdirect up for sale in July.
It is currently developing a new B2B2C (Business to Business to Consumer) platform, which will allow distributors to set up their own non-advised business stream.
