SAN FRANCISCO, 03/25/2025 – Silverstream AI, a company focused on advancing the development of autonomous web agents, today emerged from stealth. It announced the closing of its $1.2M pre-seed funding round, led by Gradient Ventures, Google's AI-focused seed fund, with the support of Vento Ventures. This investment reinforces Silverstream AI's commitment to fostering a transparent, private, and user-aligned ecosystem for building reliable AI agents capable of understanding and interacting with the modern web.
Developers of autonomous agents still struggle to achieve consistent reliability in web interactions due to the lack of high-quality datasets for training. Recent research highlights that larger, more comprehensive datasets are key to closing this performance gap. As part of its mission to enable a trustworthy AI agent community, Silverstream AI also announced the upcoming release of Pasta-1T, the largest open dataset of web trajectories designed for training web agents. This dataset will be freely available to researchers and developers, eliminating one of the most significant barriers to equal technological access. Pasta-1T aims to become a foundational resource for advancing agentic AI technology in a collaborative, open, and transparent way.
"Autonomous agents are among the most critical technological advancements of this century. They should remain open, just like the pillar technologies they build upon and the research published by thousands of researchers before us," said Silverstream AI co-founder and CEO Manuel Del Verme. "The road to reliable and trustworthy web agents is long and will require the developer community to come together with a hacker mindset, embracing shared knowledge, transparency, and a user-first approach."
This funding enables Silverstream AI to expand its team, sponsor open-source developers working on promising projects, and accelerate the development of foundational elements to deploy web agents at scale.
"LLM deployment spurred the growth and adoption of new infrastructure offerings (vector DBs, model routers, serverless GPU platforms, etc.). As foundation models gain an interface to the internet and browser-based agents come online, new software tooling will be required. Silverstream AI is designing and building these solutions, from datasets to evaluation tools for enterprises," said Vig Sachidananda, Investor at Gradient. "We're excited by what they've built so far and to support them on their journey."
Researchers in Silverstream AI’s early access community can expect Pasta-1T to be available in April. Broader access is anticipated in the summer.
