Ritesh Arora is CEO of BrowserStack and a serial entrepreneur who has started multiple companies alongside co-founder Nakul Aggarwal. Prior to BrowserStack, they co-founded QuarkRank (one of the first AI powered sentiment engines), QuarkBase (in the top 8,000 websites by traffic globally at the time) and Downcase (a consulting company with global clients). While building the website for Downcase, they became frustrated with the inability to test what they were building across a range of devices and browsers. To solve this problem, they built the first version of BrowserStack. The rest of the history is still being written.
