Obot AI Secures $35M Seed to Build Enterprise MCP Gateway

Investment accelerates the development of the open-source Obot MCP Gateway and Nanobot MCP Agent Framework

SAN FRANCISCO, Sept. 23, 2025 /PRNewswire/ -- Obot AI, an open-source software company building secure, enterprise-ready platforms for the emerging Model Context Protocol (MCP) standard, today announced a $35 million seed funding round.

The round was co-led by Mayfield Fund and Nexus Venture Partners.

The new capital will support Obot as it expands the development of its open-source projects, including the Obot MCP Gateway and Nanobot MCP Agent Framework, and grows its engineering and product teams. Launched in August 2025, the Obot MCP Gateway offers a unified, open-source control plane that enables IT teams to manage and secure MCP servers and build MCP-enabled AI solutions.

"The MCP standard is reshaping how organizations adopt AI," said Sheng Liang, CEO of Obot AI. "But without a standard platform, companies struggle with fragmentation, governance, and integration challenges. Obot AI is building an Enterprise MCP Platform so every organization can safely adopt, scale, and innovate with AI assistants."

As more enterprises integrate AI tools and capabilities, IT leaders are grappling with the challenge of providing access while maintaining control and ensuring safety. The Obot MCP Gateway addresses this gap by giving organizations a clear path to adopt new technology. Nanobot introduces a full agent framework built around MCP and MCP-UI, paving the way for rich AI agents capable of delivering a dynamic UI directly within the chat interface.

"Enterprises urgently need a way to unlock the value of AI assistants while ensuring governance, security, and trust," said Ursheet Parikh, Partner at Mayfield Fund. "Obot AIs MCP Platform is the missing piece of enterprise infrastructure, and we're thrilled to support Sheng and his team as they bring this vision to life."

"The Obot team has a proven track record of building critical open-source infrastructure platforms for developers and enterprises," said Jishnu Bhattacharjee, Managing Director at Nexus Venture Partners. "We believe Obot AI will become the standard foundation for how enterprises integrate AI tools and agents."

Obot's founding team previously created Rancher Labs (acquired by SUSE) and Cloud.com (acquired by Citrix), two companies that redefined how enterprises adopt open-source platforms at scale. With Obot.ai, the team focuses on doing the same for AI technologies.
