Sunnyside
Costa Mesa, California, United States
I spent nearly two decades on the brand side (Quiksilver, Volcom, Pacsun, Mophie) hiring and managing agencies, and watched too many of them optimize for the wrong things. In 2020 I founded Sunnyside, a performance marketing agency built around one principle: marketing should be a profit center, not a cost. We bridge the gap between finance, creative strategy, and paid media so brands grow in a way that actually shows up on the P&L. I'd never worked at an agency before building one. But after years managing them as a client, I had a clear picture of what was broken and how to fix it. We work with lifestyle, outdoor, apparel, and DTC brands. Our clients include Brixton, Municipal, Xcel Wetsuits, Beek, Nixon, and Jetty. Outside the agency I write about performance marketing, brand-building, and what it actually takes to build something without a playbook. I'm also a drummer, a surfer, a proud dad of two daughters, and a lifelong Detroit sports fan.

Sunnyside is a profitability-first marketing partner...
Sunnyside's first priority at any new client is understanding the P&L, margin structure, and spend efficiency β talking to the Head of E-Commerce and CFO before the marketing team; paid channels are the last thing they touch, not the first.
The agencies Matt hired and fired during 20 years on the brand side consistently showed great ROI numbers while the business was quietly losing money; the flaw was optimizing for the metrics the agency controlled rather than the profitability the client needed.
The most common issue Sunnyside finds isn't weak creative or inefficient spend β it's that the marketing team is running campaigns on products the e-commerce team barely bought, with messaging that doesn't match the website, with none of the teams talking to each other; Profit360 fixes the alignment before fixing the ads.
Capping at 15 clients is deliberate; it signals to clients that they're getting genuine strategic attention rather than being one of 200 accounts managed by junior account managers, and it correlates with the 2.5-year average retention that funds the business.
Sunnyside uses Claude and Notion as a unified operating system for all reporting and workflow, with MCPs connecting everything β but the philosophy is 'how can AI make what we're doing better' rather than 'what can AI do for us'; an AI consultant on retainer helps the team stay current and avoid plateauing.
Sunnyside's embedded model β physically showing up, being in lockstep with internal teams, showing up at the office multiple times a week β directly enables Profit360 to work; you can't align teams you don't sit with.
Before discussing tactics or channels, Matt's first question in any sales conversation is: 'If we were high-fiving in a year or three years from now, what would have had to happen?' β this orients the entire engagement around the client's actual desired future state.
Matt Raminickβ , founder and CEO of β Sunnysideβ , built a performance marketing agency on a thesis that came from nearly 20 years on the brand side: agencies optimize for impressive decks and growing top lines while their clients’ margins quietly erode. At Quicksilver, Volcom, and PacSun, Matt hired, managed, and fired agencies β and noticed the pattern every time. When he founded Sunnyside in 2020, he did the opposite: no agency background, no focus on channel metrics, and the first person he asks to speak with at a new client is never the marketing team β it’s the CFO. The result is Profit360, a proprietary framework that rebuilds alignment between marketing, creative, and e-commerce before a single ad is placed.
