Tech City chief executive Joanna Shields is to step down from her role after 15 months in the job.
Shields, who will retain the unpaid role of Tech City chairman and join the London Stock Exchange Group as a non-executive director, will be replaced by BlackBerry World marketing chief Gerard Grech.
Having taken up her Tech City role in October 2012, Shields oversaw the scheme's various pushes to enhance the reputations of tech startups based in East London, looking to make London the go-to tech business hub of Europe. During 2013, she also sought to increase connections between London's tech businesses and others based across the UK.
On the announcement, Shields said: "The government has created a policy landscape that's transformed the UK's startup scene. Our goal now is to build on these foundations and help growth-stage businesses scale rapidly and generate jobs."
Grech is said to have experience in working and striking deals with tech startups and venture capitalist firms including Nokia Growth Partners, as well as Seedcamp, Techstars and Entrepreneur First.
"He is an east London resident who's had a front-row seat in the evolution of web and mobile platforms over the past decade," said Shields. "He brings a strong combination of startup and corporate development knowledge to the team plus many years experience in developing and marketing digital products and services."
Grech added: "London has become a leading centre for digital innovation and entrepreneurship and my role, together with Joanna and the team, will be to help take things to the next level, delivering on key initiatives, introducing more partnerships and further solidifying Tech City in the international tech scene."
Grech will take control of Tech City, which has boasted a great deal of economic success in recent months, but will also be required to continue to help solve some of the more pressing problems blighting such a concentrated area of small tech firms.
A shortage of both suitably skilled staff and venture capitalist investment are problems cited by numerous firms and business leaders in the area. He will begin his role on 3 February.
