Stack Overflow launched the Stack Internal product suite for enterprises at Microsoft Ignite, aiming to transform internal technical Q&A into a trusted knowledge source for AI Agents. The platform outputs metadata such as Q&A, tags, authors, timeliness, and consistency scores through a dedicated MCP (Model Context Protocol) interface, providing reliability weights for agents to avoid hallucination generation.
CEO Prashanth Chandrasekar revealed that there are anonymous "large customers" who have paid to access the service, with its API licensing model similar to Reddit's content transactions exceeding $200 million. CTO Jody Bailey stated that the future system will support "read-write bidirectional" interactions: if an Agent identifies a knowledge gap, it can automatically generate new questions and send them to relevant experts, and after the answers are returned, they will be scored again, forming a self-enhancing knowledge graph.
Stack Internal does not directly build Agents, but focuses on the translation layer from "human experience" to "AI consumable format". It is planned to be fully commercialized in Q1 2026, supporting on-premise and multi-cloud deployment, and billing based on the number of Q&A entries and API call volume.
