Algolia achieves its vision by enabling more than 17,000 customers including Under Armour, Stripe, Petsmart, Walgreens, Proctor & Gamble, Sony, NBC (Universal), British Telecom and Citibank, to build blazing fast and relevant search and discovery experiences for their in-app users and/or online visitors (using any web, mobile or voice device) – by surfacing the desired content instantly and at scale.
