ChatGPT now has more than 700 million weekly active users.1 Imagine if an agent from your company could be present where those users already are, ready to help, sell, or resolve issues in real time. That is the promise of agentic AI.
Rather than building yet another app or chatbot, businesses can now create AI business agents that live inside ChatGPT and are discoverable by users the moment they need help.
For marketers, this represents a shift in how brands show up, how customers engage, and how value is created.
An AI business agent is more than a chatbot. It is purpose-built AI that can:
When published to ChatGPT, the agent becomes part of the user’s natural AI workflow, not a destination they have to seek out.
There are two primary ways users can interact with business agents inside ChatGPT.
Much like selecting an app, users can:
For brands, this is a familiar model. Discovery relies on:
This approach works well for intentional interactions, where users know which brand they want to engage with.
The more powerful model is implicit routing. Here, the user does not choose your agent at all. They simply chat to ChatGPT as normal. For example, asking “Can you help me with my grocery delivery issue?” ChatGPT recognises the intent and routes the conversation to the most relevant business agent. The agent then takes over seamlessly, within the same chat.
Behind the scenes, the agent may:
To the user, it feels like one continuous conversation. To the brand, it is a moment of high-intent engagement, delivered without friction.
In advanced setups, a single brand agent can orchestrate multiple specialised agents, such as:
The user never sees this complexity. The agent acts as the brand’s brain, while ChatGPT provides the setting and the audience. This is a fundamental shift from today’s experience of jumping between websites, apps, and chat windows.
For marketers, AI business agents introduce a new distribution and engagement layer.
Key implications include:
1. Discovery moves upstream
Customers no longer need to search for your site or app. Your brand can appear at the moment of intent, inside a tool they already use.
2. Experience becomes the brand
The agent’s tone, decisions, and helpfulness are now part of brand perception.
3. Funnel boundaries blur
Support, commerce, and marketing converge in a single conversation. The traditional separation between acquisition, conversion, and service starts to break down.
4. Platforms matter more than channels
ChatGPT becomes a primary interaction surface, much like search or social once were.
With this opportunity comes responsibility. When an agent acts on behalf of a brand, it must:
For marketers, this means closer collaboration with product, data, legal, and customer teams than ever before.
AI business agents in ChatGPT are not just a new tool; they are a new go-to-market surface.
The brands that win will not be the ones that simply “have an agent”, but the ones that design agents as living expressions of their brand, able to meet customers where they already are, at the right moment.
