Hydrogen Advertising

Seattle, Washington, United States

Brand strategy, identity, and media planning for clients like Thumbtack and WSECU

Hydrogen Advertising works across planning, research, brand strategy, and market analysis for Seattle-area and national clients, including Thumbtack, WSECU, and Puget Sound Energy. The agency describes itself as full-service, covering the range from initial brand development through to media buying and reporting.

Brand development, brand guidelines, brand identity, and logo design sit alongside website design, art direction, copywriting, and social media production. Media strategy, planning, buying, and analytics round out the offering, with reporting tied back into campaign decisions. Michael McGrath serves as Chief Creative Officer, Jason Gearhart directs account management, and Greg Tamura leads media; Mary Knight, President, also sits on the Board of Directors for Worldwide Partners, of which Hydrogen is a shareholder and board member.

Recent work includes a summer campaign for Thumbtack built around original illustrations from Seattle artist Eleanor Doughty, along with campaigns for WSECU and Puget Sound Energy. Two case studies, "Powering Moments" and "Brand Launch," document how brand and media work come together for clients moving from strategy into market execution.
