TL;DR: Braintrust CEO Ankur Goyal shows how Codex lets his team spin up 100 feature prototypes in the time it once took to try one, turning Slack requests into customer-testable previews in under ten minutes. ## From Backlog to 10-Minute Prototype Ankur Goyal, founder & CEO of Braintrust, explains that before Codex a user request had to “go into the backlog, get prioritized, and maybe see daylight weeks later.” Now he copies the message straight out of Slack, pastes it into Codex, and “within 10 minutes we have a preview branch that customers can click and play with.” ## Real-Time Ideation With Customers The bigger payoff, says Goyal, is the conversation that happens next: “We get to iterate and ideate on feature requests with the customer in real time.” Because the prototype is still “molten,” users shape the direction while the code is hot, leading to “higher-quality feedback and wilder ideas.” ## 100 Experiments Instead of One Closing the loop, Goyal summarizes the cultural shift: “I don’t just try one idea with Codex—I try a hundred.” Source: [What Codex Unlocks for Braintrust – OpenAI](https://www.youtube.com/watch?v=pLyVlqhaieI)
