Parallel Web Systems, the startup founded by former Twitter CEO Parag Agrawal, has recently successfully completed a $100 million B-round financing, boosting the company's valuation to $2 billion.
This round was led by the renowned venture capital firm Sequoia Capital, with existing investors Kleiner Perkins, Index Ventures, and Khosla Ventures also participating. Currently, Parallel has around 50 employees in Palo Alto, California. The company raised $100 million in its A-round financing last November, with a valuation of $740 million, bringing the total funding to $2.3 billion so far.

Agrawal stated that Parallel will use this funding to expand its sales and marketing teams and enhance its R&D capabilities. As a company less than three years old, Parallel aims to serve enterprise customers by providing an efficient AI agent platform that helps them perform various tasks online. Agrawal emphasized that in the future, AI agents will use the internet more frequently than humans, and therefore, specialized infrastructure is needed to support this.
AI agents may need to conduct in-depth research in areas such as investment, risk underwriting, insurance claims processing, and government contracts—tasks typically completed by humans using web browsers. However, AI agents can perform these tasks faster and on a larger scale. Andrew Reed, a partner at Sequoia, pointed out that Parallel's success is closely linked to the rapid development of long-running AI agents. These agents can operate autonomously in the background and maintain context for extended periods, thus completing user requests more quickly.
The AI legal startup Harvey is using Parallel's platform to support its AI agents, automating many research-intensive legal tasks. Gabe Pereyra, president and co-founder of Harvey, said that although it may seem simple, providing web search functionality for AI agents is not easy. They need more detailed control over the websites accessed by AI agents, and Parallel meets this need.
Parallel states that more than 100,000 developers are already using its infrastructure, including AI startups and large enterprises. Parallel is competing in the market for AI agent technology alongside other companies, and Reed called it an "obvious" huge market. Agrawal is confident about the future of Parallel and stated that the company will continue to expand its product offerings and customer base.
