Jensen

I build the growth engine mid-market companies actually run — and I’ve spent two decades owning the number to learn how. Not a deck. Not a campaign. A machine that pays you back.

Brian Jensen, Founder and Fractional CMO of Agency34 BRIAN JENSEN · FOUNDER

I’ve sat in your seat.

I’ve owned the number, defended the budget, and been the one explaining a flat quarter to a board. That’s the difference. Most consultants hand you a strategy deck and disappear; I build the operating system a growth team can actually run — and I care about the P&L line, not just the marketing-qualified one.

Across twenty-plus years I’ve run marketing for household consumer brands and demanding industrial ones alike — from wine at E. & J. Gallo to award-winning sweeteners at SweetLeaf to woodworking machinery at Grizzly. I lead with data and straight talk, and I put every available tool — AI included — to work growing the businesses I take on. Smaller budget than the enterprise players? Good. You don’t out-spend them, you out-focus them.

How he works06 / The method

Diagnose, sequence, build, prove

One operating loop, run with your team, then repeated as the truth changes — so growth compounds.

DIAGNOSE

Find the leak

Get into your data and find where revenue is actually leaking — demand, retention, pricing, or AI visibility.

SEQUENCE

Highest return first

Fix the lever that pays back fastest, then the next. No boiling the ocean, no template.

BUILD & PROVE

One system, one dashboard

Wire demand, performance, lifecycle and AI search into one engine — with metrics that tie to the P&L.

“I don’t hand you a deck and disappear. I build the machine — and stay to make sure it pays you back.”
