Figma shares popped another 6% in premarket after jumping 7% on Monday after the design software vendor’s technology was promoted by OpenAI CEO Sam Altman in an onstage demo at his company’s annual DevDay conference in San Francisco.

Altman discussed Figma’s integration into ChatGPT, which has more than 800 million monthly users. He showed how third-party applications could plug in with OpenAI’s Apps SDK, or software development framework.

“When someone’s using ChatGPT, you’ll be able to find an app by asking for it by name,” Altman said. “For example, you could sketch out a product flow for ChatGPT and then say, Figma, turn this sketch into a workable diagram. The Figma app will take over respond and complete the action.”

In addition to asking for Figma’s help by name in ChatGPT, the assistant can also suggest Figma when it’s relevant, Figma product manager Luke Zhang said in a blog post.

The rally for Figma, at its high point, was the steepest since the day of the company’s public market debut on the New York Stock Exchange in July.

Figma has been ramping up its own tools for working on app and website designs using generative AI models from OpenAI and other providers.

Subscribers to products that connect to the Apps SDK will be able to log in without leaving their ChatGPT conversations, Altman said. He said people working on products in Figma can also launch the FigJam tool to keep working on development ideas. Apps SDK is based on the Model Context Protocol, an open standard that OpenAI rival Anthropic introduced last year.

Software developers will be able to submit apps for review later in 2025, Altman said.

Over time, OpenAI will offer many ways to generate revenue through third-party integrations, Altman said. Last week, OpenAI announced a feature allowing people to buy products listed on Etsy through ChatGPT.
