Parag Agrawal, former Twitter CEO, has launched Parallel Web Systems with $30 million in funding from investors including First Round Capital, Index Ventures, and Khosla Ventures. The startup aims to build a new AI-focused web infrastructure designed specifically for machine consumption rather than human browsing.

Parallel's flagship product is a deep research API that recently outperformed OpenAI's GPT-5 by 33 points on the BrowseComp benchmark, achieving 58 percent accuracy compared to GPT-5's 25 percent. This API enables AI agents to efficiently retrieve, validate, and organize web content, completing tasks that would take humans hours in just minutes.

Unlike traditional search engines, Parallel's infrastructure is tailored for AI systems, enabling real-time internet interaction and programmable web inquiries. Early applications include financial analysis tools for regulatory filings, coding assistants that synthesize documentation, and AI sales agents conducting lead research.

Agrawal, who holds a PhD from Stanford and studied at IIT Bombay, envisions Parallel as a cornerstone of the future web architecture, leveraging experience from top tech companies like Twitter, Google, Stripe, and Airbnb.

"Parallel is creating the tools and APIs needed for AI agents to efficiently retrieve, validate, and arrange web content," the company states.

The startup plans to expand into continuous monitoring systems and long-horizon AI agents, aiming to revolutionize how AI interacts with the web and accelerates data-driven workflows.

This new venture marks Agrawal's return to the tech scene after leaving Twitter in 2022 following Elon Musk's takeover, signaling a bold step toward building the "web for machines."
