What Martinelli Environmental Graphics does

Martinelli Environmental Graphics is a privately held, founder-owned architectural sign manufacturer and contractor based in San Francisco, California. Founded in 1989 by Jack Martinelli after two decades in the sign industry, the company designs, fabricates, and installs custom interior and exterior signage for corporate, institutional, retail, hospitality, civic, and healthcare clients, with Northern California as its core market and additional projects delivered nationally. Its service offering spans the full project lifecycle — design/build, prototype fabrication, shop- and engineering-compliant drawings, permit acquisition, and installation — and is organized around six product categories: ADA-compliant signage, donor recognition systems, interior signage, monument signage, electrical signage, and custom letterforms.

The company's manufacturing capabilities center on custom fabrication in a broad material set — bronze, aluminum, stainless steel, stained wood, with bead brail, romark letters, illuminated letterforms, pan-formed construction, and silkscreened finishes — alongside regulatory competencies including ADA code compliance and licensed-bonded contractor status that permits it to pull city signage permits on a client's behalf. The business is operationally small (headcount reported at 11–50), with leadership concentrated in Owner/President Jack Martinelli and Vice President Jeff Osicka, and operates from a single fabrication facility at 1829 Egbert Ave., San Francisco.

Revenue is generated almost entirely on a project-based, custom-quote basis, with no standardized pricing tiers and no recurring SaaS, maintenance, or licensing component. Go-to-market is direct-to-project via specification-level relationships with tier-1 architecture firms (Gensler, HOK, Perkins+Will, Interior Architects) and major general contractors (Turner, DPR, Webcor, Swinerton, Rudolph Sletten), augmented by co-design partnerships with boutique wayfinding and design firms such as Clearstory, Public Design, Urbain Design, and Square Peg Design. Named end clients include the Golden Gate Bridge, California Academy of Sciences, Lucile Packard Children's Hospital, Genentech, Boston Scientific, Grand Hyatt SFO, Virgin America, and Marin County Sheriff Department.
