About Nester

Built to be the media buying partner brands actually trust.

Nester exists because too many European brands hand their ad budget to agencies that report on impressions and clicks instead of revenue. As a performance marketing agency serving the EU, we do it differently. Every campaign is judged by whether it actually grows the business.

We work as an extension of your team: transparent about what's working, honest about what isn't, and fast to react to the data.

A philosophy Ernest builds every campaign around

"If you can't measure it, you can't improve it."

— Peter Drucker

With 8+ years running Google Ads, plus deep experience across Meta Ads, Ernest has worked both in-house, managing budgets from the client side, and agency-side, running paid media for brands across multiple industries. That dual perspective shapes how Nester operates, favoring what actually moves revenue over agency theater. He has built and scaled campaigns across Search, Shopping, Meta, and TikTok, with a track record of turning ad spend into predictable, defensible ROAS rather than vanity metrics.

What We Believe

The principles behind every campaign

01

Data-driven, not opinion-driven

Every decision is backed by performance data, not gut feeling or platform hype.

02

Radically transparent

You get full visibility into spend, performance, and reasoning, with no black-box reporting.

03

ROI-obsessed

We optimize for revenue and profitability, not vanity metrics like reach or impressions.

04

Fast-moving

Ad platforms change weekly. We test, react, and reallocate budget quickly rather than waiting on quarterly reviews.
