Phil Jeynes (pictured) is set to leave UnderwriteMe at the end of August.
Jeynes joined the protection platform in 2015 working alongside chief executive Martin Werth and his senior team.
Werth said: “I want to thank Phil for his considerable support over the past four years.
“During this period, he has been a key part of the team who made our underwriting rules engine the number one in the UK, as well as taking the protection platform from concept to a major player in the market, delivering over 100,000 sales in the first half of 2019.
“We wish Phil all the best in his future endeavours.”
Jeynes added: “I’m very proud of what we’ve achieved at UnderwriteMe in the last few years and excited for the next challenge in my career.
“I wish Martin and the rest of the team continued success.”
