What Poss does

POSS is a privately held, employee-owned architecture, interior design, and planning practice founded in 1976 by Bill Poss in Aspen, Colorado. The firm is headquartered in downtown Aspen with additional offices in Carbondale, Colorado and Boise, Idaho (opened 2022), and operates across three integrated disciplines: architecture, interior design, and planning. It serves ultra-high-net-worth residential clients, luxury hospitality developers and operators (Montage International, St. Regis, Timbers Resorts, The Little Nell, Aspen One), and select commercial and institutional customers such as Bank of Colorado, Brunello Cucinelli, Moncler, and Hines.

Revenue is generated exclusively through bespoke, project-based professional services fees. Engagement terms and pricing are not publicly disclosed; each project is initiated through a website inquiry followed by discovery and proposal work. The go-to-market motion is sales-led and reputation-driven, anchored by founder and leadership brand recognition in mountain design, sustained earned media (Luxe Interiors + Design, Mountain Living Magazine, Wall Street Journal), an active blog and social presence, and community ties through the Aspen, Boise, and Carbondale Chambers of Commerce. There is no software or platform business: POSS's "technology" is its design methodology, its five-decade portfolio, and its internal talent-development program (POSS University, founded 2008) that cultivates a deep bench of architects aligned with the firm's timeless, context-sensitive design philosophy.

In 2024 the firm completed a generational ownership transition, with Andy Wisnoski (CEO/Managing Partner), Kevin Morley (VP of Architecture), and Rachel Guest (VP of Interior Design) becoming partners/owners. The firm is currently celebrating its 50th anniversary, supported by a 2025 brand refresh, and operates approximately 40+ named professionals across its three locations.
