Jeff Rimmer.

Jeff Rimmer has spent more than twenty years in marketing on every side of the table. He has worked inside startups and inside Fortune 100 companies. He has founded and run several businesses of his own, including a music platform he took from a blank page to hundreds of thousands of users. And he has been the outside partner to clients across that same range, from a founder with a napkin sketch to enterprise teams serving millions of customers.

That mix is the point. Jeff sits at the intersection of creative, strategy, branding and AI: he can write the positioning, direct the creative, build the growth engine and wire the intelligence underneath it, and he has done each of those jobs for real, with his own budget on the line. His deepest experience is in music and entertainment, retail and ecommerce, and healthcare and wellness, three industries where attention is expensive and trust is everything.

He founded Extra Medium to give ambitious businesses one senior partner who thinks like an owner, builds like a studio and measures like an operator. Today he serves as fractional CMO for companies in the US and UK and leads every Extra Medium engagement personally. He works from Virginia Beach and travels regularly to Chicago and the UK.

What he actually does for clients.

As fractional CMO he owns strategy, budget, team and results: paid media across Google, Meta, TikTok, Reddit and creator channels, lifecycle email and SMS, ecommerce and Shopify growth, brand and positioning decisions, reporting and AI-driven marketing operations. As principal of Extra Medium he leads every engagement personally, from brand strategy and go-to-market to applied AI and experiences.

Perspective.

Jeff writes the studio's thinking: why most growth problems aren't advertising problems, what to check before increasing paid media spend, when a company needs a fractional CMO instead of another agency, and how AI can connect a company's operations instead of becoming another disconnected tool.
