The risk profiling business will invest the money in creating the third generation of its Dynamic Planner software - Dynamic Planner Elements.
The new version will allow advisers to meet Mifid II rules on suitability and charges disclosure, as well as increase the efficiency of their operations.
Ben Goss, chief executive of Dynamic Planner, said: "Dynamic Planner Elements will future proof advice firms in an increasingly demanding and technology driven financial planning market.
"What we are announcing today is the largest single investment in our 15-year history.
"The Elements programme is a key part of strategy to scale our position as firms’ number one service for ensuring investment suitability while delivering on our vision of seeing suitable advice and investments available to all."
The new version of Dynamic Planner will include mobile-first technology and is built to integrate with other firms' systems through its enhanced API.
It will also provide "lifestyle-magazine quality" reporting which can be white labelled and configurable to firms' compliance standards.
The first release in the Elements programme covers the client review process and is being launched today (January 24) after a year in development.
It is aimed at allowing advisers to meet their Mifid II requirements without leaving Dynamic Planner and the company said it would reduce the time taken to complete reviews "from hours to minutes".
Dynamic Planner is used by more than 6,500 financial planners and the company recently passed the milestone of 1 million clients being serviced by its technology.
