What Third & Arch does
Third & Arch is a Philadelphia-headquartered branding and marketing agency that delivers brand strategy, visual identity design, website design and development, research, and campaign services exclusively to Architecture, Engineering, and Construction (AEC) firms. The firm operates as "a Push10 Agency," indicating it is a specialized brand or division within Push10, its strategic operating parent. Its operating model is a project-based professional services business: prospective AEC clients submit inquiries through a website contact form, dedicated account managers consult on goals, and bespoke project engagements (logo design, brand identity systems, full website builds, marketing campaigns) are scoped and delivered. Pricing is not publicly disclosed and is quoted per project on consultation.
The company's technology footprint is conventional for a creative agency — it does not operate a proprietary platform, does not expose an API or SDK, and has no documented integrations, products, or AI capabilities. Distribution is anchored in a direct, consultative sales motion targeted at established mid-to-large AEC firms, primarily in the Northeast US. The firm supplements outreach with owned-media channels — a blog with multiple named contributors, LinkedIn, Instagram, an email newsletter, and SEO-optimized site pages — and attends the Amplify AEC industry conference as its flagship event channel.
Third & Arch's named customer base spans roughly 18 enterprise AEC accounts across its three priority verticals, including Conti Federal (global construction/engineering), Smith Seckman Reid (engineering), Hankin Group (real estate development), Remington & Vernick Engineers (450+ professionals), Blackney Hayes Architects, Arium AE, Apeiro Design, Larson Design Group, and Becker & Frondorf, among others. The agency self-describes as intentionally midsize to preserve quality and cross-discipline expertise (strategy, design, development), combining boutique attention with broader corporate capability — a positioning it uses to differentiate against generalist marketing agencies.
