You Can’t Charm an AI Agent Over Dinner — But You Can Pass Its Background Check. Here’s How.

Picture a founder who runs a promising software company. Solid product, happy customers, decent website. One day, a Fortune 500 company in her exact target market goes looking for a vendor that does precisely what she does. She never gets a call. She never even knows the deal existed.

Here’s why. Nobody at that enterprise ran a Google search and skipped her listing. Instead, an internal AI agent did the first pass. It read vendor documentation across the market, checked third-party coverage, scored security signals, looked at integrations and handed a human buyer a shortlist of five names. Hers wasn’t on it. Not because her product was worse, but because the machine couldn’t verify her claims in the few seconds it spent looking.

This isn’t a thought experiment anymore. Nvidia’s enterprise AI platforms now sit underneath autonomous agents being embedded directly into SAP and Salesforce, the systems that run procurement and sales at much of the world’s largest companies. And Gartner predicts that by 2028, AI agents will be involved in 90% of B2B purchases, steering more than $15 trillion in spending. Your website, your press coverage, your product documentation: none of these are being read only by humans anymore. They’re being read by machines that decide whether you ever make the shortlist at all.

Marketing now has a third audience

For roughly two decades, marketing meant one thing: ranking in Google. That discipline is called search engine optimization, or SEO and it’s built around keywords, links from other sites and technical polish. The audience was a human typing a query.

Then AI chatbots became the new front door to information, and a second discipline emerged: generative engine optimization, or GEO. The goal of GEO is to get your company mentioned and recommended when someone asks a tool like ChatGPT, Perplexity or Gemini a question such as “what’s the best payroll software for a 50-person company?” The audience is still a human, but one reading an AI’s summary instead of a list of links.

Agent-to-agent marketing, or A2A, is the third layer now arriving on top. It doesn’t replace the other two. It adds a new audience entirely: the autonomous software agents doing research on behalf of enterprise buyers. And this audience is fundamentally different, because it isn’t reading for persuasion at all. It’s scanning for verifiable proof. It is, more or less, running a background check on your business.

In the A2A era, the job isn’t to charm a machine. The job is to pass its verification.

Your press coverage is now a background check
