Key point

With the rise of LLMs, forum traffic has plummeted, but Stack Overflow is surviving by expanding revenue through data licensing and AI solutions.

Details

With the emergence of powerful code-writing AIs like ChatGPT and Claude, traffic to Stack Overflow's Q&A forums has plummeted. The recent monthly question count is around 6,866, which is only at the level seen when the service first launched in 2008.

However, Stack Overflow's corporate revenue is actually growing. Annual revenue has nearly doubled to about $115 million, and cost reductions have also significantly narrowed the company's losses.

The revenue structure has completely shifted from the existing ad-centric model to one targeting the AI ecosystem.

  • Stack Internal: A generative AI add-on built on millions of Q&A data points, now adopted by 25,000 companies worldwide.
  • Data Licensing: Generates revenue by selling its vast trove of data to AI companies for AI model training.

Ultimately, Stack Overflow is turning the crisis brought on by LLMs into a new business opportunity, using the trustworthiness of the data built up by its community as its core asset.
