Zozimus

What Zozimus does

Zozimus is a privately-held, Boston-based digital marketing and public relations agency founded in 2004 (originally as 451 Marketing, rebranded to Zozimus in 2025) that serves mid-size to large B2B clients across 11+ industry verticals including higher education, medical device, finance, hospitality, consumer goods, furniture retail, pet products, and non-profit. The firm operates on a custom-quoted professional services model, billing predominantly on an annual retainer or project basis for integrated engagements spanning digital marketing, paid media, SEO, social media, creative, brand strategy, public relations, CTV, and out-of-home advertising, and supplements agency revenue with grant-funded corporate training delivered through its Zozimus University sub-brand.

The agency's central technical asset is Zozimus Predict, a proprietary predictive analytics model that ingests weekly channel-level data (paid search, paid display, organic, direct mail, lead generation, experiential, email, OOH, networking) and produces KPI, revenue, and campaign-performance forecasts surfaced through interactive dashboards. This forecasting layer is wrapped by a service portfolio that now includes dedicated Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) practices designed to position client content for citation by ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews, plus an agentic-AI workflow stack integrating third-party models (Claude, ChatGPT, Jasper, Midjourney, Runway) and tools such as Sprout Social, GA4, Northbeam, Klaviyo, Bombora, Nosto, and Dynamic Yield.

Zozimus is led by founding partners AJ Gerritson, Nick Lowe, and Thomas Lee, alongside EVP of Digital Marketing & Analytics David Wilson, and reports 51-100 employees operating from a single Boston headquarters at 25 New Chardon St. The firm claims cumulative client revenue of more than $3 billion generated since founding and maintains multi-year relationships with clients such as On Deck Sports (10+ years) and Bryant University (three consecutive years of record-breaking application volumes). Go-to-market relies on enterprise field sales, direct website inquiry, and an event-driven thought-leadership motion anchored by the founding partners' conference speaking circuit.
