Werth founded UnderwriteMe in 2012.
Martin Werth will be stepping down as chief executive of UnderwriteMe at the end of March.
Werth will become a non-executive director and continue to be directly involved with the business.
Werth founded UnderwriteMe in 2012 with Pacific Life Re backing.
James Tait will take over as chief executive and was formerly a non-executive director of UnderwriteMe.
Werth said: “This has been a really hard decision.
"Setting up and growing the business is a full-on venture that can’t be sustained forever.
"The best time to step down is following a record-breaking year.
"We have built a great management team and James is an excellent person to lead the business in its next growth phase.
"As a Non-Executive Director, I will continue to stay close to the business.”
Tait added: “UnderwriteMe has experienced phenomenal growth since it launched in 2014.
"The business is now a leading provider of underwriting technology in many markets around the world and the protection platform in the UK is helping intermediaries transform the way protection is sold.
"I am looking forward to leading the team and the business through its next phase of growth and building on the strong foundations that Martin Werth has put in place.
"I would like to thank Martin for his vision and commitment to UnderwriteMe.”
