Henry Gooss is to step up to head the private equity arm of Investor, Sweden's largest investment holding company, when his boss, Börje Ekholm, replaces Marcus Wallenberg as chief executive of the whole group in September.

Investor, in which Sweden's wealthy Wallenberg family owns a 44% stake, has been one of Europe's most successful venture capital firms under Ekholm with an annual return on its money of more than 20%. The private equity arm was founded by Ekholm and Gooss in 1998.
