We built something that could not survive one person leaving.
That was a flaw in how we built it, not proof of how good anyone was. This company is the correction.
Underboss Media is founder-led by Don Mateo Blazeka, the operator named and accountable for every engagement while every client stays anonymous under NDA. He has run organic distribution for consumer companies since 2023, built and funded an owned consumer app to a 10,000-person waitlist with no paid media, and built the company so the engine does not depend on him.
I lost my own money on this before I asked anyone to spend theirs.
950M+lifetime organic views
10,000-person waitlist, built on our own money and no paid media
Growth that lives in a person is growth on loan.
Ours included, which is how we found out.
We ran organic for a consumer gaming company for five months and produced 50 million views with no paid media behind any of it, and search for the company's own name went up close to ten times. Then the engagement ended. The demand did not collapse, it settled at roughly twice where it started and stayed there. But it stopped climbing, because nobody was running the engine. That is the whole industry in one story. You rent the operator, the operator goes, the climbing stops. So we rebuilt it so the judgment lives in a written playbook instead of in a person, ours included. That is Underboss.
Senior operators forever is a story, not a model.
It gets promised at the pitch and quietly dropped by month three.
What we do not sell
Senior operators doing every piece by hand forever. It is a story told at the pitch and quietly dropped by month three, and it does not scale.
What we do sell
One lead on the record, a team that executes, and a system built so the output holds when any one of us walks. Clients anonymous, operator named.
Don Mateo Blazeka
Operator, Underboss MediaOne name answers. A team runs it.
Runs organic distribution for consumer companies, on the record since 2023: roughly 100 million views that year, 350 million in 2024, 500 million in 2025, 950 million and counting across every account on the operator record. Built and funded an owned consumer app to a 10,000-person waitlist with no paid media, and spent about four thousand euros of his own on a paid test for the same product that returned nothing. Based in Europe, remote. Every client anonymous under NDA; every number sourced on the proof page.
