Acquisition brings one of the industry’s most recognized independent creative shops into Chemistry and marks the opening of its fifth U.S. office

PITTSBURGH and BOSTON, Oct. 7, 2026 /PRNewswire/ — Independent agency Chemistry today announced its acquisition of Boston-based creative agency Colossus, adding award-winning creative and design talent to the agency and bringing Chemistry into the Boston market. The acquisition strengthens Chemistry’s design capabilities and establishes Chemistry Boston, the agency’s fifth U.S. office.

The deal brings together two agencies that have built their reputations on standout creative work, entrepreneurial cultures and senior talent that stays close to clients. Both have the accolades to match. Among their many honors, Colossus was named an Ad Age Small Agency of the Year three times, earning honors for Healthcare in 2026, B2B in 2025 and Design in 2024. Chemistry was named a 2026 Ad Age A-List Standout, following its #6 ranking on the Ad Age A-List in 2023, and is also a three-time Ad Age Small Agency of the Year.

“This starts with the people,” said Ned Show, CEO, Chemistry. “Colossus has built an incredible creative business and an exceptional team. We saw an opportunity to bring that talent into Chemistry, strengthen what we can offer our clients and create more opportunities for our teams. We’re not acquiring just to get bigger. We’re adding great people who make Chemistry even better.”

Colossus brings deep expertise in brand identity, design systems and visual storytelling, giving Chemistry a dedicated design capability while establishing the agency’s presence in Boston. The acquisition gives Chemistry an immediate foothold in one of the country’s leading creative markets through a highly regarded, award-winning team with significant momentum. In the past year alone, Colossus added work from Adobe Acrobat, Wellness Pet Company, Kayem and Astound Broadband; partnered with Moderna, Google, Microsoft and MIT to rebrand Kendall Square; and won an Emmy for its film about autism with The Daily Show’s Jon Stewart.

For Colossus, joining Chemistry creates a broader platform for its people, clients and work while preserving the culture and creative strengths that have driven the agency’s success. Colossus clients will gain access to Chemistry’s integrated capabilities across creative, production, strategy, branding, design, social, research and analytics, media, public relations, digital, web development, Hispanic marketing, SEO and technology solutions, while Chemistry clients will benefit from the additional talent and award-winning creative expertise Colossus brings to the agency.

“From the beginning, Chemistry felt like the right fit,” said Jon Balck, Co-Founder and Managing Director, Colossus. “We share a belief in distinct and effective work, in how we partner with clients and, most importantly, in building a place where talented people can do their best work. Joining Chemistry gives our team and our clients access to so much more without losing what made Colossus special in the first place, which is incredibly important to us.”

The acquisition comes after seven consecutive years of growth for Chemistry and marks the agency’s first major deal since partnering with Breakwater Management in 2025 to support its next phase of growth. Over the past two years, Chemistry has continued to expand its capabilities and client roster. The Colossus acquisition reflects Chemistry’s approach to growth: adding exceptional people and complementary capabilities that make the agency better and create more opportunities for both clients and employees.

Chemistry Boston joins the agency’s existing offices in Atlanta, Pittsburgh, New York and Miami.
