OpenAI's Sales AI Gives Reps an Extra Day Each Week

When your go-to-market team triples in size while launching products almost weekly, the wheels start to come off. That was the situation inside OpenAI, where sales reps were burning an hour prepping for a 30-minute call, hopping across dozens of systems to find context. Meanwhile, hundreds of product questions from customers piled up, drowning subject matter experts and gumming up deals.

The fix wasn’t a new dashboard. It was an internal tool called GTM Assistant, built on OpenAI’s own automation platform and delivered in Slack. The system zeroes in on two daily pain points: it generates meeting briefs with account history, call notes, and Salesforce activity, and it answers product questions instantly using a curated knowledge base with links back to source documents.

Here’s the part that actually matters: top-performing reps didn’t just use the tool—they trained it. They worked directly with GTM Assistant to define what a high-quality briefing looks like, embedding their expertise into the system. Every correction and evaluation scaled their best habits across the entire sales org. Kate Huhn, who worked on the project, put it bluntly: “We were constantly going back and forth on what does good look like here, really inspecting responses and operationalizing ‘good’ inside of our system.”

The numbers are concrete. Reps now exchange 22 messages a week with the Assistant and see a 20% productivity bump—roughly an extra day each week to spend with customers or manage a larger book. The team reviews samples weekly, patches gaps, and pushes updates. Huhn describes it as “a virtual coworker that we re-skill every single week.” Customers feel it too—questions that used to languish in Slack get answered in minutes, and meetings start sharper. The pilot is now expanding into logging CRM updates, flagging usage patterns, and drafting follow-ups automatically. The real insight here is structural: by making sellers co-owners of the technology, OpenAI built a system where knowledge flows freely and the whole organization gets elevated, not just the stars.
