Zoopla Property Group's founder and chief executive, Alex Chesterman, is to step back from day to day operations at the end of the month.
Chesterman will remain on the ZPG board as a significant investor and will continue to advise on product, strategy and merger and acquisition opportunities.
The move follows Silver Lake's £2.2 billion acquisition of ZPG, which completed in July.
One of the country's best-known digital entrepreneurs, Chesterman founded ZPG in 2007. Since then, the organisation's annual revenue and EBITDA have grown to over £300 million and over £120 million respectively.
Alongside his work with ZPG, Chesterman has backed dozens of digital startups, including Graze, Perkbox, WeSwap and Uniplaces.
Following its stock market float in 2014, ZPG has expanded with a number of acquisitions, most notably uSwitch and Hometrack.
ZPG's property division will continue to be run by Charlie Bryant, former chief executive of Hometrack. The group's comparison division - which includes uSwitch and Money - will be run by newly-appointed Tariq Syed.
"After ten years of developing and growing ZPG into a multi-billion pound market-leading business, now is the right time for me to step down as CEO," says Chesterman.
"I am incredibly proud of what the team has achieved, having transformed the markets we operate in for both our consumers and partners."
"ZPG has enormous potential to grow further and I look forward to remaining involved with the company as a board member, investor and strategic adviser as well as being able to focus more time on some of my other investments and interests," he says.
Simon Patterson, managing director of Silver Lake, adds: "What Alex and his team have achieved with ZPG over the past 10 years is an incredible growth story, building some of the UK’s most recognised and widely adopted digital brands."
"We are looking forward to growing the business further on the very solid foundations they have built. Alex is one of Europe’s most accomplished technology entrepreneurs and we are delighted that he will remain on the board as a significant equity investor and will continue to advise the business on product, strategy and M&A opportunities going forward."
