Direct peers

• Tangram Interiors: Multi-regional Herman Miller/Certified Dealer with design, furniture, flooring, and AV integration capabilities across the Western US—closest comparable in operating model to BSI's integrated partner approach.
• Atmosphere Commercial Interiors: Herman Miller Certified Dealer headquartered in Minneapolis offering integrated commercial interior design, furniture, and AV services across the Upper Midwest—directly comparable to BSI in scale, dealer status, and integrated service model.
• Office Environments International (OEI): Herman Miller Certified Dealer providing workplace strategy, furniture, architectural products, and AV integration—highly comparable integrated service model targeting enterprise commercial customers.

Broad incumbents

• HOK: Global design, architecture, engineering, and planning firm with interior design practice serving corporate, healthcare, education, and government clients—a large-scale incumbent competing for the same Wisconsin-based enterprise accounts.
• Haworth: Privately held global office furniture manufacturer with its own direct dealer network—a competing OEM whose strategy (including direct enterprise sales) poses channel-economics risk to BSI's MillerKnoll-aligned model.
• Steelcase: Largest office furniture manufacturer in North America with direct dealer network—a competing OEM whose product breadth and dealer program overlap with MillerKnoll, constraining BSI's competitive positioning if clients pivot away from Herman Miller brands.
• Gensler: Largest global architecture and design firm with deep interior design practice and offices across major US metros—the dominant incumbent BSI competes against for flagship corporate headquarters and large commercial interiors work.
• MillerKnoll: Parent of Herman Miller and Knoll—BSI's flagship furniture partner since 1969 and the dominant contract furniture OEM whose Certified Dealer network economics directly govern BSI's furniture business.
• IA Interior Architects: Global interior architecture firm with 30+ offices serving Fortune 500 clients—a larger-scale competitor on architectural scope that BSI often competes against for premium corporate HQ engagements.

Others

• DIRTT Environmental Solutions: Manufacturer of modular walls and prefab interior construction solutions—a BSI technology partner that also sells directly and through competing dealers, representing both a strategic partnership and adjacent technology category.
