CEO: MATHILDE COLLIN VALUATION: $1.7 BILLION CUSTOMER COMMUNICATIONS

“Maybe because I’m French, and I’m more skeptical than the average person, but I prefer underselling and overdelivering,” says cofounder and CEO Collin, who sat out megawatt funding rounds to focus on quieter growth instead. But with 2,500 new customers onboard since 2020, she relented enough to take on $65 million in June, which finally made Front a unicorn. Her company’s software tools help businesses including Airbnb and Shopify communicate and track correspondence with their customers.
