Are LLMs Becoming the First Gatekeeper in SaaS Discovery?

I’ve been thinking about something that feels small at first — but might be structurally important.

When founders think about discovery, we think:

SEO

Content

Ads

Product Hunt

Social

But increasingly, I’m noticing something different.

Before users ever click a website, they ask ChatGPT, Claude, Gemini, Perplexity:

“Best alternative to X?”

“What’s the best CSV import tool for React?”

“Affordable Flatfile alternative?”

“Best vector database?”

These models summarize, compare, and recommend.

That means they’re shaping positioning before the buyer ever visits your site.

So I started testing a hypothesis:

If your product isn’t consistently reinforced in these AI-generated comparisons, you’re invisible at the moment the decision narrative is formed.

Not bad SEO.
Not bad ads.
Just… absent from the summary layer.

To explore this, I built a small system that:

Runs structured category queries across ChatGPT, Claude, Gemini, and Perplexity

Tracks which competitors are reinforced by default

Measures how your product is described (or omitted)

Detects drift between how you position yourself vs how AI positions you

I’m not treating this as “AI SEO.”
I’m treating it as infrastructure research.

Is this a new gatekeeper layer?

Is competitive positioning now partially mediated by LLMs?

Does this change how early-stage SaaS companies build authority?

I’m opening 10–15 paid beta spots to founders who want to test this with me and pressure-test the hypothesis.

Not looking for mass signups.
Looking for thoughtful builders who care about positioning.

Curious if others here are noticing the same shift.
