Parag Agrawal, former CEO of Twitter, has made a strong comeback in Silicon Valley with his artificial intelligence venture Parallel Web Systems Inc. The company, founded in 2023 after Agrawal’s exit from Twitter under Elon Musk’s ownership, has now launched its flagship innovation—the Deep Research API.
Headquartered in Palo Alto with a 25-member team, Parallel has raised $30 million from leading investors including Khosla Ventures, First Round Capital, and Index Ventures.
The Deep Research API is designed to help AI systems perform large-scale web research with human-level and beyond-human accuracy. According to Agrawal, the system has already been adopted by several fast-growing AI companies and enterprises to automate workflows, debug code, and integrate advanced web intelligence into their platforms.
“We already power millions of research tasks every day,” Agrawal wrote on LinkedIn, adding that the API has outperformed both humans and leading AI models, including GPT-5, on two of the toughest benchmarks.
The launch marks Parallel’s bold entry into the competitive AI research tools space, positioning the startup as a direct challenger to established players.
