# Thomas

> Thomas is a North American industrial supplier-discovery platform that turned a famously unwieldy 34-volume directory into a searchable network of more than 500,000 suppliers. Buyers use it to identify, filter, compare, shortlist and contact manufacturers; suppliers pay for premium visibility, buyer-intent data, product catalogs and industrial marketing services. Xometry bought the business for $300 million in 2021, pairing Thomas's demand and supplier data with instant quoting and a transactional manufacturing marketplace.
