Donut Labs has raised $15 million in seed funding as it builds what it calls “a quantitative AI inside a browser.”
The funding came from investors including BITKRAFT, HSG, Makers Fund, Sky9 Capital, Altos Ventures and Hack VC, along with contributors from the Solana, Sui and Monad ecosystems, according to an emailed announcement on Monday.
The seed round comes less than six months after Donut Labs raised $7 million in pre-seed funding.
Led by CEO Chris Zhu, Donut Browser said it aims to transform the way users interact with the financial Internet by incorporating autonomous merchant agents directly into the browsing experience. These agents analyze markets, calculate risk, and execute on-chain trades, even when users are offline.
The potential intersection of AI agents and blockchain technology is seen as a game-changer by some crypto industry observers. Using smart contracts, self-custody, and joining different chains can be complex for humans, but an AI agent could be specifically customized to thrive in that environment.
Donut, which has amassed more than 160,000 users on its waitlist, plans to use the funds to develop a monetizable agent browser capable of orchestrating real-time market intelligence and automated execution.
Donut’s rise comes amid rising decentralized trading volumes, with DeFi derivatives surpassing $1 trillion in monthly activity. Zhu said Donut is “redefining trading as something as natural as typing: a browser where your quantitative AI works for you, 24/7.”
