UNUM collaborative

What UNUM collaborative does

UNUM Collaborative, LLC is a Denver, Colorado-based architecture and interior design firm founded in 2017 (with project history dating to 2012) that operates as a privately held LLC with 1-10 employees. The firm delivers full-service architectural design, interior design, and custom installations across residential, hospitality, restaurant, brewery, workplace, retail, and institutional sectors. Its core methodology, branded as a "multisensory design philosophy," emphasizes tactile, olfactory, and auditory experience alongside visual aesthetics, executed through a "collaborative creation framework" that integrates clients, consultants, fabricators, and builders. Key principals Adam Steinbach and Jim Pfeiffer serve as Principal in Charge across the portfolio, which includes signature projects such as Firefall Ranch Resort (150-acre, 55 cabins, Groveland, CA), Great Divide Belmar (8,500 sq ft brewery), Cholon Restaurant Group locations, Left Hand RiNo (8,600 sq ft tasting room), and the Periscope House Marshall Fire rebuild.

The firm's go-to-market is enterprise field sales built on direct client engagement, principal-led relationships, and a content-forward marketing strategy spanning portfolio website, social media (Instagram, Pinterest, Facebook, LinkedIn), a monthly newsletter, podcast appearances, and earned media in Forbes, AFAR, Modern in Denver, and 5280 Home Magazine. Revenue is generated through project-based professional services fees quoted per engagement based on scope, size, and complexity, with no publicly disclosed pricing tiers. Customer concentration is anchored by repeat hospitality clients (Cholon Restaurant Group, Great Divide Brewing, Left Hand Brewery, Pearl Street Hospitality) supplemented by custom residential and commercial work. The firm maintains a tight recurring partnership ecosystem with construction (Colson Builders, ATG Builders, Novum Contracting, Parallel Construction, Jordy Construction), engineering (MEC Engineering, D Keller Electrical Design), fabrication (LVTD Design), and photography (Fernando Gomes) partners. Geographic focus is regional across Colorado, California, and Nevada.
