Front, the email startup valued at $1.7 billion, is undergoing a significant leadership change as Mathilde Collin steps down from her role as CEO to become the Executive Chair, and Dan O'Connell is hired as the new CEO. This transition comes as Front celebrates the 10-year anniversary of its seed round led by Uncork. Collin, who founded Front a decade ago and grew it into a billion-dollar company by the age of 32, announced the change, expressing she is 'super proud' of the company's progress and 'excited for its next chapter'. The leadership shift marks an inflection point for Front, with Collin focusing on her new role while continuing to work for the company. She was on the hunt for a new board director at her thriving startup when she asked her top pick, Dan, to replace her.
