Christoph Klink is a former McKinsey partner who moved from boardrooms to day-zero investing at Antler, where he works with people before they even have finalized ideas or teams—positioning himself as a partner for validating what to build rather than just funding existing startups. He leads large analyses on European founders and designs structured cohorts with team challenges to create the right conditions for founders to test multiple co-founder configurations before committing, emphasizing teams first and ideas second.
