Artificial intelligence data provider AfterQuery Inc. has secured $30 million in funding, valuing the startup at $300 million. Altos Ventures led the investment round, with participation from Y Combinator, The Raine Group, and BoxGroup.
San Francisco-based AfterQuery supplies datasets crucial for training AI models. The 14-month-old company reports a customer base including "every leading AI lab" and achieved over $100 million in annual recurring revenue prior to this funding.
AfterQuery's datasets go beyond simple prompt-response pairs, incorporating a step-by-step breakdown of the thought process behind each response. This feature aids AI models in applying learned lessons to new tasks. The company also offers datasets optimized for specific AI training stages, such as reinforcement learning, and generates them with input from nearly 100,000 developers, attorneys, and other professionals.
The company's offerings extend to evaluation suites for measuring AI training effectiveness and development environments complete with APIs and MCP servers. AfterQuery also provides virtual sandboxes that simulate organizational environments for developing task-automating AI agents.
Proceeds from the funding will support the expansion of AfterQuery's expert network and workforce, alongside enhancing its enterprise business, which includes custom AI agents.
