Former Twitter Chief Executive Officer Parag Agrawal has launched Parallel, a startup that aims to redesign the internet for autonomous artificial-intelligence agents rather than human users. Parallel closed a $30 million seed round led by Khosla Ventures, with participation from Index Ventures and other backers. The Palo Alto-based firm plans to use the capital to hire engineers and develop what it calls a “parallel web” optimised for machine-generated traffic. Agrawal says AI programs will soon surpass human activity online, requiring new search, data-access and security layers. Parallel’s first application-programming interface, now in private testing, is touted as outperforming humans and OpenAI’s GPT-5 on deep-web research tasks. The venture marks Agrawal’s first major project since his 2022 dismissal following Elon Musk’s takeover of Twitter. After two years focused on AI research, he is betting that the next phase of internet growth will be driven by non-human users—and that fresh infrastructure will be needed to support them.
