Firewood, MediaMonks, and Circus Named Fastest Growing Agencies by Adweek


The results are in: Firewood, along with S4 Capital sister companies MediaMonks and Circus, was named to the annual Adweek 100: Fastest Growing list for the second year in a row. The Adweek’s Fastest Growing honors the 100 top agencies and 10 top solution providers—large and small, from all over the world—whose industry presence is on the rise. All three companies were also ranked among Adweek’s Top 10 Fastest Growing Large Agencies (over 200 employees).

Because the list honors international agencies spanning every category, type, and size that have achieved significant growth, we’re honored to be in such good company. But we’re especially excited to stand with our S4 sister companies as three individual partners that have since banded together to offer a distinct, differentiated offering to brands seeking to innovate and resonate with digital audiences today—and while our approach is resonating with brands, we’re just getting started.

“I’m thrilled to see that it isn’t just MediaMonks that made the Adweek 100: Fastest Growing feature, but also our amazing colleagues at Circus and Firewood,” says Wesley ter Haar, founder of MediaMonks. “The mind wanders at what happens when you put three of the fastest growing agencies into a unitary structure and single P&L—there are many great things to come, and I’m looking forward to it.”

Independently, we continue to serve brands with the signature offering that made us each great from the start—with a continued passion for the clients and work that got us added to this list in the first place. MediaMonks is a premium digital experience partner, helping brands better understand and digitally connect with their audiences and build brand love in the process. Circus is a multicultural, fully integrated digital agency that partners with its clients to develop high-impact ideas, strategies, and content that wins in the attention economy. And founded on the belief that good people are good business, Firewood is a pioneer of the “embedded” model, building in-house creative, strategy, and technology teams that become extensions of its clients’ teams—and amplify their power.

Throughout 2020, these capabilities have helped brands show up in significant ways. Together, we gave sports fans the best seat in the house (their house), we brought people together as they marched for Pride from their living rooms, we extended the world’s most innovative AR/VR conference into AR and VR, and we’ve helped scale teams up while others have pulled back—facilitating not only our own growth, but that of our client partners as well.

“All of us come from a very different non-agency mindset,” says Juan Zambrano, cofounder of Firewood. “We’ve been disruptors from the start, and our goal has always been to support our clients at scale delivering speed, quality, and value across the board—particularly at a time when taking a digital-first approach has become essential.”

Our goal has always been to support our clients at scale delivering speed, quality, and value across the board.

“Circus’ roots lie in breaking new ground with impactful ideas led by data, fed by emotion and built at scale,” says Bruno Lambertini, founder of Circus. “As we look toward the future, we look forward to further empowering brands through greater collaboration and a cohesive offering with MediaMonks and Firewood.”

We’ve grown alongside our clients through this commitment to shared success. Together, we’re offering brands a one-stop solution as a best-of-breed partner in the digital marketing space. The results are advanced marketing and advertising technologies with world-class creative, strategy, and production on a global scale.

We believe innovation doesn’t wait. Let’s keep moving.
