A Studio of People Who'd Rather Run Your Campaign Than Pitch It.

CS & Co. Marketing Studio™ is a division of Mainstream Entertainment Group Inc., headquartered in Plainview, New York. We're a small, deliberate team of CTV operators, strategists, and creatives — built around one founder's conviction that great media buying happens in the work, not in the deck.

Founder & CEO

Cory Poccia

Founder & CEO, CS & Co. Marketing Studio™

Cory Poccia has been in the media business since 2004 — a 22-year career that started in film and music production, evolved through brand strategy and creative direction, and arrived at the place he's been building toward all along: a CTV-first agency built around the metrics his clients actually report to their boards.

He founded CS & Co. Marketing Studio™ in 2017 as a division of Mainstream Entertainment Group Inc. — initially as a video production and creative shop with deep roots in story-driven brand work. As streaming television matured into the most measurable advertising medium in history, Cory transitioned the studio's center of gravity into CTV media buying, with one non-negotiable principle: the agency's compensation would never come at the expense of its clients' performance.

That principle drove the elimination of the 15% commission, the elimination of monthly retainers, and the construction of a success-fee model that only triggers when client KPIs are independently verified. It is, by most accounts, the most aggressively client-aligned commercial model in U.S. CTV.

Cory is also a faculty member at Adelphi University in Garden City, New York, where he teaches Media and Artificial Intelligence at the university level. He is one of the only practicing CTV agency founders in the United States actively teaching the convergence of streaming media, generative AI, and performance attribution to the next generation of strategists. His academic work informs the agency's methodology — and vice versa.

Outside the studio, Cory is the founder of the Entrepreneurs' Organization Accelerator Program (Long Island Chapter), where he mentors founders scaling from $250k to $1M in revenue. He is 10X Marketing Certified and a longtime Muay Thai practitioner — a discipline that, in his own words, "teaches you the difference between speed and panic." Both show up in how he runs the agency.

The Studio

Small Team. Senior Operators.

No Junior Hand-Off.

One of the quiet truths of agency work is that the team that pitches you is rarely the team that runs your account. We don't operate that way. CS & Co. is small by design — a deliberate studio of senior operators who do the work themselves. The people you meet are the people running your campaign.

Taylor S.

Director of Strategy & Client Operations

Taylor leads client strategy and account operations at CS & Co. — translating CMO-level objectives into the campaign architecture, KPI frameworks, and weekly reporting rhythms that the rest of the studio executes against. Before CS & Co., [career background to be added]. Taylor is the operator who keeps every engagement honest to the success-fee model: if the KPIs aren't being measured against the contract, Taylor catches it before the client does.

Aryeh S.

Head of Media & Performance

Aryeh runs day-to-day media operations across the studio's CTV portfolio — bid optimization, inventory curation, audience activation, and the real-time adjustments that separate a campaign that compounds from one that plateaus. Background in [to be added]. Aryeh is the reason every CS & Co. media plan stays inside premium PMP inventory and never drifts into open-exchange remnant.

Damian S.

Creative Director & Production Lead

Damian leads the studio's creative and production work — from CTV-grade video production through dynamic creative versioning and AI-augmented content generation. Roots in [to be added]. Damian is the reason CS & Co. clients never have to choose between performance and craft: every spot is built to be watched at 95%+ completion, and to convert when it is.

Cara H.

Director of Attribution & Measurement

Cara owns the attribution and measurement infrastructure behind every CS & Co. engagement — pixel implementations, incrementality tests, geo-controlled holdouts, and the CFO-grade reporting that makes the success-fee model possible. Background in [to be added]. Cara is the operator who ensures every success fee is earned against a number the client's CFO can independently reproduce.

Headquarters

CS & Co. Marketing Studio™ operates out of our headquarters in Plainview, NY — a working creative and media studio that houses our production stage, post-production suite, and media operations team under one roof. We don't outsource the craft. We don't subcontract the buy. The work happens here.

The Parent Company

A Division of Mainstream Entertainment Group Inc.

CS & Co. Marketing Studio™ is the CTV-first division of Mainstream Entertainment Group Inc., a media and production company with roots in film, music, and brand entertainment. The parent company structure means CS & Co. has access to a deeper bench of creative, production, and post-production talent than its size would suggest — and it means our clients are working with a studio backed by more than two decades of operating history, not a venture-funded startup running on a 24-month runway.
