WhoAPI Inc. provides application programming interfaces (APIs) that convert raw domain data into structured, machine-readable formats like JSON and XML. The company was founded in 2011 by Goran Duskic, a serial entrepreneur with a background in the web hosting industry. Inspired by the lean startup methodology, the company began with just a landing page to validate the idea and take pre-orders before any infrastructure was built.

Goran Duskic's journey into the tech world began with developing freeware PC games, which led him to co-found a successful web hosting business in Croatia in 2006. He and his business partner developed the idea for WhoAPI while running the hosting company, eventually selling the first business to focus entirely on the new venture. A significant milestone occurred in 2012 when their pitch won the Geeks on a Plane conference in Zagreb, which led to their participation in the 500 Startups incubation program in Silicon Valley. This victory helped them secure pre-seed funding from 500 Startups, Isaac Saldana, and other investors, which financed the creation of their first API version and official incorporation.

The company's business model is subscription-based, offering various monthly and yearly plans for its suite of APIs. WhoAPI serves a diverse clientele, ranging from developers, startups, and marketing agencies to large corporations and Fortune 500 companies such as Google, Twitter, and King. Its core service is the Whois API, which provides parsed domain registration data. Over time, the company has expanded its product line to include a Domain Availability API, a Screenshot API for capturing website images, an IP Blacklist API to check domains against spam lists, and unique offerings like Domain Score and Email Score APIs that provide reputation ratings. These tools enable clients to monitor websites, protect their brands from domain squatting, conduct market research, and support cybersecurity efforts by identifying potential threats.
