What Aeterna Group does

Aeterna Group is a U.S.-based architecture and engineering collective formed in June 2026 by Signal Hill Equity Partners through the consolidation of five pre-existing regional firms: CSArch (New York), ZMM Architects and Engineers (West Virginia), Kluber Architects + Engineers (Illinois), KGD Architecture (Washington DC), and Omni Associates Architects (West Virginia). The collective employs over 230 design professionals across 13+ offices in seven states (Illinois, Massachusetts, New York, Ohio, Virginia, West Virginia, and Washington DC) and delivers three core service lines — Architecture, Engineering, and Interior Design — across verticals including K-12 and higher education, federal/state/local government, healthcare, multifamily housing, community and recreation, transportation, science and technology, and commercial and industrial facilities.

The underlying technology stack consists of industry-standard CAD, BIM, and design software platforms used to produce architectural, structural, mechanical, electrical, and civil engineering deliverables. There are no disclosed proprietary technology products, software platforms, APIs, or AI-native systems; the business is fundamentally a labor-intensive professional services model where revenue is generated per project by credentialed design staff. Each founding brand retains its regional identity, client relationships, and operating offices, while sharing back-office resources, leadership, and business development under the Aeterna Group umbrella.

The revenue model is project-based professional services delivered through direct engagement with government entities, educational institutions, healthcare systems, and commercial/industrial clients, typically secured via RFP processes and existing relationships. Pricing is quote-driven and not publicly disclosed. The go-to-market motion is sales-led and enterprise-oriented, targeting long-cycle institutional capital programs. Customers include named public-sector and institutional clients such as the City of Aurora, the Institute for Defense Analyses, The Aerospace Corporation, West Virginia University, the University at Albany, and Northwestern Memorial Healthcare. The company is privately held with no public financials disclosed.
