StackOne Streamlines AI Agent Integration
StackOne makes it easy for businesses to adopt AI by automating the complex work of connecting different AI tools. This saves weeks of developer time and speeds up secure AI integration. With a simple interface and ready-to-use connectors, there’s no need for custom coding or complicated setup. StackOne also ensures strong security and data privacy, so teams can safely test and scale AI solutions. Built-in features like monitoring, access controls, and usage tracking give businesses full visibility and control over their AI tools—helping them move faster while reducing overhead.
Built by Engineers Who Felt the Pain
Founded by Romain Sestier and Guillaume Lebedel, both former engineers at Google and Yieldify, StackOne was born out of deep industry experience and frustration.
“We saw how much time teams were wasting on integrations,” said Sestier. “StackOne is the platform we always wished we had—one that automates the messy parts of scaling AI in enterprise.”
Why Google Ventures Invested
Luna Schmid, a partner at Google Ventures, explained why the firm believes StackOne is a game-changer:
“StackOne is building core infrastructure for the AI agent world, with secure design, fast delivery, and a strong product vision that sets it apart.”
