Colossus has quietly made Boston an advertising city again: Ad Age Small Agency wins in back-to-back years (Design 2024, B2B 2025) plus an Adweek fastest-growing nod, on work that ranges from hot-dogs-in-Revolutionary-War-paintings for Kayem to a Jon Stewart-fronted nonprofit campaign.
Their humor-forward, craft-secure style suits challenger brands and CMOs who want fame on a mid-size budget. Fast Company called them advertising's best hope against the industry's oligarchy — the work mostly backs the hype.
