This week was Advertising Week in New York City - one of the most recognized event for marketers. At vibe.co, we wanted to stand out, and so here’s what we did.

The play

We deployed 12 LED trucks across Manhattan, each displaying one simple question and a QR code:

Scan it, and you’d land on a pre-filled ChatGPT prompt ready to go, no marketing copy, no banner ad, just an invitation to ask the machine itself.

The result? A real-time conversation where AI became our salesperson (we literally drove traffic to chatGPT).

The strategy: hacking the LLM layer

We didn’t just run an ad. We ran an experiment in LLM visibility.

Here’s the thing: in 2025, large language models are becoming the new search engines. They don’t crawl keywords, they reason. And what they “know” about a brand isn’t based on backlinks or bids; it’s built from the context they’ve learned across the web.

By seeding thousands of high-intent interactions around a specific query —

Essentially, we’re optimizing not for SEO clicks, but for LLM cognition.

The impact

In less than 24 hours:

• 1,000+ QR scans

• 3,000+ site traffic boost

• Dozens of new backlinks, brand mentions, and prompt interactions feeding directly into the AI knowledge graph

• Social media blast (and a viral tweet from Vibe’s CEO)

Why I think this matters

As AI continues to mediate how people find products, platforms, and ideas, brand presence in LLM outputs will define visibility.

Owning your prompt space means owning your position in AI-driven reasoning, before the rest of the industry even realizes that’s the next battleground.

And honestly, we had fun setting this up.
