Canadian Marketing Firm 42 Agency Visits Boston for HubSpot Unbound 2026

B2B marketing consultant 42 Agency has once again relied on a mobile billboard ad campaign to publicize its presence at HubSpot’s annual conference in Boston MA. Featuring a cheeky set of messages running as a slide show on the mobile digital billboard truck’s three LED screens, the truck spent several days circulating around the Thomas M. Menino Convention & Exhibition Center during the conference.

In addition to its immediate focus on convention attendees arriving at and leaving the convention center throughout each day of the conference, the truck also looped around popular nearby restaurants and hotels which are favored by convention visitors to Boston.
