Build an AI Sales Team with OpenAI’s Agent Builder

December 05, 2025

You can now build a fully autonomous AI sales team without writing a single line of code.

OpenAI has officially launched a platform that helps you build AI agents and workflows visually. This talented creator demonstrated exactly how to use this new “Agent Builder” to create a system that finds leads and drafts emails automatically.

Over the next year, Roku predicts that 100% of the streaming audience will see ads. For growth marketers in 2026, CTV will remain an important “safe space” as AI creates widespread disruption in the search and social channels. Plus, easier access to self-serve CTV ad buying tools and targeting options will lead to a surge in locally-targeted streaming campaigns.

Read our guide to find out why growth marketers should make sure CTV is part of their 2026 media mix.

The big shift here is moving from reactive chatbots to proactive agents. A chatbot waits for your question, but an agent takes a goal and figures out the steps to achieve it. The expert showcased a visual canvas where you drag and drop “nodes,” which are basically little workers with specific jobs, and connect them to create a pipeline.

Here is how the expert structured this powerful automation:

The Three-Agent Relay System

Instead of asking one AI to do everything, the innovator split the job into three distinct specialized agents. First, a “Lead Finder” searches the web for specific targets, like video production companies in Chicago. It passes that raw data to a “Data Entry Agent,” which formats the info and logs it into a Google Sheet. Finally, an “Outreach Agent” reads that sheet and drafts a personalized email in Gmail. By keeping the roles narrow, the author ensured the AI didn’t get confused or hallucinate steps.

The “MCP” Connection Hack

The most technical part of this build is connecting OpenAI to the real world. The creator used something called an MCP (Model Context Protocol) server via Zapier. Since the Agent Builder doesn’t natively talk to Google Sheets or Gmail yet, Zapier acts as the bridge. The expert set up an MCP server that creates a secret handshake (API key) between OpenAI and his apps. This allows the agent to actually do work, like creating a row in a spreadsheet or creating a draft in Gmail, rather than just talking about it.

When training takes a backseat, your AI programs don't stand a chance.

One of the biggest reasons AI adoption stalls is because teams aren’t properly trained. This AI Training Checklist from You.com highlights common pitfalls and guides you to build a capable, confident team that can make the most out of your AI investment. Set your AI initiatives on the right track.

Guardrails and Proactive Prompting

Success relies heavily on “System Instructions.” The professional emphasized that you can’t just say “find leads.” You have to write detailed instructions for each node, explaining exactly which columns to fill in the spreadsheet. He also tweaked the settings to “never require approval” for tool calls, allowing the agent to run autonomously without asking for permission at every step. However, he warned that this is still in beta; it took him a few tries to get it right, so it’s best for internal tools rather than public-facing apps right now.
