The Sipp firm bought institutional stockbroker Lawshare in 2007 with a view to launching its own stockbroking platform.
Chief executive Andy Bell says the firm will be launching the platform in the coming months, followed by an Isa and a personal dealing account over the next year to 18 months.
The provider will also be offering advisers that have their own discretionary management service the chance to outsource back-office functions to AJ Bell.
He says: “We want to spread our wings and widen our product range beyond Sipps.”
