Atolio

The platform operates by integrating with a company's existing applications—such as Microsoft 365, Google Workspace, Slack, and Salesforce—and indexing the data within the client's own private cloud environment on AWS, Azure, or GCP. This self-hosted approach ensures that a company's data and intellectual property remain under its control, a key differentiator for clients in regulated industries or those with strict data sovereignty requirements. Atolio's system respects existing permissions and access control lists, meaning employees can only search for and retrieve information they are already authorized to view.

The business model targets mid-size to large enterprises, including government and nonprofit sectors, that require a secure way to leverage large language models (LLMs) for internal knowledge discovery. The platform allows clients to use their preferred LLMs without the risk of training public models on their private data. In September 2025, Atolio announced it had raised a total of $24 million in funding, with a Series A round led by Translink Capital and including investors like IBM Ventures and Bloomberg Beta, to accelerate product development and scale operations. The company has secured multiple seven-figure contracts and is used by clients to enhance the productivity of go-to-market teams by making customer and product information more accessible.
