asm-slash ABOUT About

Assembly is a fast-growing, modern media agency that provides brands with innovative media solutions powered by sophisticated planning and buying technologies. We are nearly 500 creative media minds and advertising technologists in a new breed model that unlocks true value for clients. We are a proud member of the MDC Partners family.






We believe that creativity is the most powerful driver of competitive advantage and business growth.

We believe that technology has never been more important in unlocking creative potential.

So, we’ve assembled the most creative media minds and advertising technologists in a new breed media model.

We call it media arts + sciences.


We are proud to have a dynamic, diverse and respected set of leaders guiding our company forward.


Our headquarters are in NYC. We currently have 450 full-time employees and offices in 5 U.S. markets.
This footprint allows us to provide clients with true national scale as well as local-market know-how.



Unlike other media agencies who have bolted on technology systems to legacy models, we have purpose-built our agency around our proprietary tech and data stack. It plans, builds, buys, and measures programmatic media campaigns and also serves as a centralized data and intelligence engine for integrated communications planning.

The benefit of this technology automation is more targeted and effective media plans, more staff spending time on value-enhancing deliverables, and less waste in delivery and cost.

asm-slash APPROACH Approach

Assembly is a full-service integrated media agency. Our capabilities include research, communications strategy, planning and buying across all channels, and advanced analytics.

And it’s an incredibly effective tool for aligning partner agencies towards shared client goals. Rollover to explore.

asm-slash PROSPECTS menu-right4you

Dear prospective client,

About 18 months ago we started speaking with CMO’s all over the country. They all shared some common frustrations about how the media agency industry wasn’t evolving fast enough to meet their needs.

So we decided to build a company to address that.

If you find yourself agreeing with any of the statements below, we’d love to talk. Rollover to explore.

It's nearly impossible to adapt when you are tied to legacy business models. Assembly is the first scaled media agency to launch in the U.S. in the past decade and is purpose-built for today.

Assembly unlocks the power of our people by automating time-consuming, mundane tasks and freeing up important time to focus on value-enhancing business contributions.

At Assembly we believe you should pay us for the difference we make to your business and we shouldn't be trying to make money with yours. We will show you invoices from all media owners to back up this commitment. Ask your current agency if they'll do the same.

Assembly is born from the creative roots of MDC Partners. We've got world-class creative partners like 72andSunny, CP+B, Anomaly and Vitro. Our main goal is to make ideas bigger and better through media.

Unlike mega-agencies, at Assembly each negotiation is bespoke. All inventory is purchased to align specifically with your brand objectives in mind. We deliver the right inventory at the best price so that clients always come first.

Don’t be shy now!

Neil.Smith@media-asm.com is eager to hear from you.
