SandBaseAI raises multi-million-dollar seed for personal agent infrastructure

What's the deal? SandBaseAI has closed a multi-million-dollar seed round to build agent infrastructure for developers. Investors included a large language model company and backers with roots in AI startup communities and developer ecosystems.

What's the endgame? The company offers a single API key that connects developers to more than 2,000 models and APIs across 100-plus platforms, plus a sandboxed agent runtime, MCP bridging, and a marketplace of pre-built skills. It targets independent developers and AI startups building what it calls "Personal Agents."

How it works: Developers define what an agent should deliver, then use SandBaseAI's data APIs to fetch information and its runtime to create sessions and run tasks. The platform bundles session management, task scheduling, and audit replay, and charges on a pay-as-you-go basis.

Founder Li Yangbing is a serial entrepreneur who previously led the cloud-native unit at Meicai and worked as an architect at DP Technology, with experience in AI for Science, multimodal systems, and agent infrastructure.

What's the money for? SandBaseAI said the funds will go toward product development and marketing. It plans to simplify data access, improve runtime stability, and promote the tools through open-source projects, task templates, and developer events. An enterprise, self-hosted version is on the roadmap.

Why now? The round lands as investors shift attention from model capability toward the infrastructure agents need to execute real tasks. In October 2026, agent-execution company Daytona raised a $60 million Series B led by FirstMark Growth at a $1 billion valuation, providing isolated environments for agents to run code and use tools.

The signal: The two companies enter from different angles, but together they show capital flowing into agent infrastructure. Daytona's larger round signals investor conviction; SandBaseAI's seed reads as an early bet, not yet proof of commercial traction or market position.
