Under cofounder and CEO Marco Zappacosta, Thumbtack is a digital platform that connects customers with local professionals to book everything from landscaping services to math tutoring. These interactions now add up to $1 billion a year in commerce, all booked through Thumbtack. Although the company, which charges service providers a fee when customers contact them in response to a quote, is not yet profitable, Zappacosta predicts it can be by the end of 2019, thanks to Instant Match, which automates the bidding process for pros and algorithmically pairs them with customers’ job requests. Introduced in 2017, the feature pushed the company’s quest to monetize local services into hyperdrive: Some pros saw their bookings increase up to 50% by year’s end. It also helped Thumbtack take a major step toward becoming a truly seamless, digital marketplace for the country’s $700 billion–grossing local services industry. As Zappacosta sees it, he’s building a platform where users can book a caterer, plumber, or hairdresser as easily as they order a book on Amazon.
