Parag Agrarwal's AI-agent startup Parallel Web Systems has reached a valuation of $2 billion along with achieving $100 million in Series B funding, according to a report from The Wall Street Journal on Wednesday.
Agrawal, the former CEO of social media platform X, known as Twitter at the time he was helming it, launched the venture Parallel Web Systems in August 2025. It specialises in servicing autonomous AI agents, with the goal to facilitate it to browse the internet on its own with accuracy and efficiency. The venture aims to provide specialised infrastructure to bring this vision to life.
The funding round for the tech startup was spearheaded by Sequoia Capital, whose capital infusion has increased the company's valuation to $2 billion. Other investors in the firm include Khosla Ventures, Index Ventures and Kleiner Perkins.
Parallel's Series A Funding was held in November 2025. having raised $100 million, taking its valuation to $ 740 million. The AI company has raised a total of $230 million.
The firm, which currently consists of about 50 employees, will use the capital to establish its sales and marketing team and expand its research and development operations, as per Agrawal. The firm will also use the money it has raised to continue its focus on enterprise clients.

Parallel's autonomous AI agents can be used by firms to undertake research for investment, risk underwriting, insurance claims processing and sifting through government contracts and other "deep research" tasks. These tasks would be accomplished by an AI agent quicker, and more accurately, as compared to a human with a web browser.
The recent interest and traction in the startup can be credited to the demand for more 'long-horizon' AI agents, according to Andrew Reed, the company's board member as well as a Sequoia Capital partner. 'Long horizon' AI agents can remember contexts and run tasks for long periods at a time and do so in the background, all while responding to user requests at a faster rate.
Companies like AI legal startup Harvey use Parallel Web Systems' services to implement more precise control over which websites its AI agents access. Harvey uses this to fine tune the legal research it undertakes for its clients.
Parallel Web Systems currently has up to 100,000 developers using its infrastructure, which includes enterprises and AI startups.
