The shift I couldn't ignore.

I spent over a decade optimising websites for Google's algorithm. The work was technical, satisfying, measurable. And then almost overnight the playing field moved.

Buyers started asking ChatGPT instead of Googling. Clinics, law firms and tech companies I'd helped to rank suddenly weren't being named in AI answers. The traffic was still there. The trust was leaking somewhere else.

Why most agencies are still selling 2015 SEO.

The honest truth: most agencies are quietly hoping AI search is a phase. It isn't.

What worked in 2015 keywords stuffed into pages, generic backlink lists, content calendars optimised for volume actively harms you in the AI era. Engines now reward citation, worthy content, structured trust signals, and brands that sound like specific humans, not optimised content factories.

What High 5 Guru actually is.

High 5 Guru is a consultancy, not a content mill. I work directly with founders, CMOs and marketing directors at firms where trust is the product.

We focus on three things: the technical signals AI engines use to decide who to cite, the authority signals that compound those citations into market position, and most uncomfortably for some agencies, the human voice that makes a brand worth choosing in the first place.

PHILOSOPHY

“AI will replace tasks. But it will amplify one truth: people will always choose people. The brands that thrive won’t be the most automated. They’ll be the most human.”

– Razvan Calarasu

Who I work with

Three sectors where trust is the product.

If you're building a brand where the buyer cares deeply about who they're trusting these are the rooms I work in.

Cybersecurity & IT

Your buyers ask ChatGPT before they ever email a vendor.

If your firm isn't named in the answer, you're not in the consideration set.
Healthcare

Patients trust visible brands. Visibility is the new bedside manner.

Clinics, private practices and wellness brands becoming the recommended choice.
Legal

Clients hire the firms they trust first long before they call.

Solicitors and consultancies engineering authority across AI answer engines.

The Book

Becoming More Human in the AI Era

Razvan’s upcoming book, How to Become More Human and Less Robotic in the New AI World, shows founders and brands how to stay visible, trusted, and memorable as AI reshapes search, content, and marketing.
