OpenAI has introduced Company Knowledge today, a substantial enterprise addition for ChatGPT Business, Enterprise, and Edu subscribers that lets the AI pull and synthesize information straight from workplace tools like Slack, Google Drive, GitHub, and HubSpot. This launch signals OpenAI’s serious play for the booming corporate AI market.

How Company Knowledge Actually Works

The feature runs on a purpose-built variant of GPT-5 engineered to process multiple data streams at once, per OpenAI’s announcement. What sets this apart is how it handles responses: you get contextually relevant information with explicit source links, all while the system honors your existing access rights across connected platforms. Activating it is straightforward—select “Company Knowledge” in ChatGPT’s composer, authenticate your work apps, and you’re running.

“Company Knowledge has changed how I use ChatGPT at work more than any other feature we’ve built,” Brad Lightcap, OpenAI’s COO, posted on social media. The system pulls context from your various workplace applications, delivering answers that actually reflect your company’s specific operations and data.

This announcement lands as OpenAI doubles down on enterprise customers following CEO Sam Altman’s promise of “significant focus” on corporate expansion at the company’s October developer event. The numbers back up this strategy: OpenAI’s enterprise base jumped from two million users in February 2025 to three million now, showing how quickly businesses are adopting AI tools.

The Enterprise AI Battlefield Gets Crowded

The timing here matters. Microsoft pushed out major Copilot updates the very same day, adding group collaboration for 32 people, tighter Google service integration, and introducing an AI avatar they’re calling “Mico.”

Google isn’t sitting idle either. Their recent Gemini Enterprise launch offers a complete AI platform at $30 per seat monthly, connecting Google Workspace, Microsoft 365, and business apps like Salesforce—positioning itself squarely against OpenAI’s enterprise play.

Industry analysis from Bain & Company indicates AI has hit its “platform phase,” where organizations are shifting from scattered AI tools toward integrated, managed systems. Bain reports 25% efficiency improvements in their own methodology through AI-driven assessment and optimization workflows.

The corporate AI market trajectory is steep: Technavio projects workplace AI will expand by $206.5 billion from 2025 through 2029, growing at 21.3% annually. With numbers like these, the intensifying competition between OpenAI, Microsoft, and Google makes complete sense—everyone wants a piece of this rapidly expanding market.
