bunch is an investment tech startup founded in Berlin in 2021. With a proven track record, bunch has garnered trust from leading fund managers and institutional LPs, who have collectively committed over €5 billion through the platform.

The private markets are experiencing unprecedented growth, with alternative assets expected to reach nearly $40 trillion by the end of the decade, yet still reliant on outdated tools and methods.

We recently closed our $15.5 million Series A to accelerate bunch's mission to bring a trillion-dollar industry into the 21st century, driving a much-needed digital transformation.
