APIs are ubiquitous in the tech world, with ⅔ of developers embracing the API-first philosophy, up five points from last year, as they began to pop up in the early 2000s to connect applications. Companies are now moving towards becoming API-first, using APIs to leverage capabilities and build innovative products, offering faster go-to-market ability and a seamless user experience. By 2023, 65% of global infrastructure service providers' revenue will be generated through services enabled by APIs. API-first companies build solutions around the API, providing an industry-agnostic or specific solution that can scale quickly and efficiently. Companies like Stripe, Twilio, and Plaid have revolutionized their respective industries with API-first approaches, while others are catching up. To succeed, an API-first company must adopt a mindset that considers all potential uses of the API, launching industry-disrupting platforms by offering API solutions to other organizations, as seen in the example of Checkr's background check API solution.
