About us

We started Prisma because marketing had stopped meaning anything.

Our story

Prisma House was founded on a simple observation: the marketing industry had become extraordinarily good at producing activity, and extraordinarily bad at producing outcomes. Dashboards multiplied. Channels multiplied. Agencies multiplied. Results didn’t.

We chose the name deliberately. A prism doesn’t create light — it takes what’s already there and reveals what it’s made of. That’s our job. Every brand we work with already has something true and valuable at its core. Our work is to refract that single beam of ambition into its full spectrum: positioning, story, content, visibility, demand.

Today we advise ambitious companies of every stripe — from venture-backed challengers to established firms re-finding their edge. We stay deliberately small, take on a limited number of clients at a time, and work directly with founders and leadership teams. No account-manager relay race, no juniors learning on your budget.

Our mission

To make marketing a source of competitive advantage again — measured in revenue, defended in boardrooms, felt in markets.

What we stand for

Four values. Zero exceptions.

01

Truth before tactics

We'd rather lose a pitch than flatter a bad strategy. Every engagement starts with an honest diagnosis, even when it's uncomfortable — especially when it's uncomfortable.

02

Fewer things, done properly

Marketing plans fail from excess, not absence. We put weight behind the handful of moves that change a trajectory, and we say no to everything else.

03

Numbers you can defend

Every recommendation must survive a finance director's scrutiny. If we can't connect the work to pipeline or revenue, we don't put it in the plan.

04

Craft is the strategy

A brilliant plan executed carelessly is a mediocre plan. We sweat headlines, decks and details, because your audience only ever sees the execution.

The founder

“I built the consultancy I kept wishing existed on the other side of the table.”

Gianmarco Giordaniello founded Prisma after a decade spent on both sides of the marketing divide — building brands in-house and advising them from the outside. He watched too many capable companies pour money into marketing that looked impressive and moved nothing, and decided the fix wasn’t another agency. It was a different kind of counsel.

As CEO, he leads Prisma’s team of senior strategists and stays personally close to every engagement — from the first diagnostic to the board presentation. Nothing carries the Prisma name without being shaped, and challenged, at the top.

His standard for the work is simple: find the one true thing a brand can say better than anyone, then cut everything that dilutes it. If a recommendation can’t survive a board’s scrutiny, it doesn’t leave the building.
