Ex-Twitter CEO Parag Agrawal launches AI startup Parallel with $30m

Former Twitter chief executive Parag Agrawal, who was dismissed by Elon Musk following the Tesla billionaire’s takeover of the social media platform in 2022, has resurfaced at the helm of a new technology venture.

Agrawal has unveiled Parallel Web Systems Inc., a Palo Alto-based startup developing tools that help artificial intelligence systems conduct large-scale research across the internet. The company, which was founded in 2023, has already raised $30 million in funding from investors including Khosla Ventures, First Round Capital, and Index Ventures, according to reports from Bloomberg and TechCrunch.

Agrawal, a long-time Twitter engineer who rose to become CEO in 2021 before being ousted during Musk’s acquisition a year later, has kept a low profile since leaving the platform, now renamed X. His re-emergence reflects both the rapid growth of the artificial intelligence sector and the demand for infrastructure that can power AI systems at scale.

On LinkedIn, Agrawal described Parallel’s mission as enabling AI companies and enterprises to harness “web intelligence” for their products. “We already power millions of research tasks every day, across ambitious startups and public enterprises,” he wrote.

He added that some of the fastest-growing AI firms are already using Parallel to integrate large-scale web research directly into their platforms and agents. One unnamed public company, he claimed, has used Parallel to automate workflows traditionally handled by humans, achieving results “exceeding human-level accuracy.”

For Agrawal, Parallel represents a significant professional comeback. His tenure as Twitter CEO was brief and turbulent, ending abruptly when Musk completed his $44 billion takeover and dismissed several top executives in late 2022.

By stepping back into the spotlight with Parallel, Agrawal is re-establishing himself not as a social media executive, but as a founder in one of the fastest-moving corners of the tech industry.

Whether Parallel can sustain its early momentum remains to be seen. The company will face competition from established players building research and retrieval APIs, as well as from foundation model developers seeking to integrate similar capabilities directly into their offerings.

Still, with a respected technical founder, backing from marquee investors, and early claims of outperforming leading AI models, Parallel has drawn significant attention as one of the more ambitious AI startups to emerge from Silicon Valley in 2025.
