What Synergi does

Synergi is a privately held specialty architectural metalwork contractor that designs, engineers, fabricates, and installs turnkey feature stairs, railing packages, windscreen systems, and ornamental metalwork for large commercial and institutional projects. Founded in 1986 in Winnipeg as Accent Brass and rebranded to Synergi in 2015, the company is headquartered in Elkridge, Maryland, with 101-250 employees operating from eight North American offices (DC metro, New York, Boston, Seattle, Philadelphia, Miami, Dallas, and the Bay Area) and a London office added via the 2026 acquisition of Alpine Group UK. Synergi's core technology combines Building Information Modeling (BIM) for design coordination, 3D-printed full-scale mock-ups, AISC-certified structural steel fabrication with AWS-certified welders, and a prefabrication methodology that reduces installation time from 2-3 weeks to 2-3 days per stair section while cutting transportation truckloads by 66-80%. Its proprietary Design-Assist Methodology embeds the company into the project's concept stage alongside architects and general contractors, enabling value engineering and guaranteed maximum pricing. The ThinkRail pre-engineered modular railing system extends the product line into faster-install, configurable railing solutions for repeat commercial deployments.

Synergi serves Fortune 500 corporate owners, world-renowned architects, and general contractors building corporate headquarters, technology campuses, financial services offices, universities, cultural institutions, and landmark developments. Named customers include Meta, Google, Walmart, Capital One, Amazon, JPMorgan Chase, Ford, T-Mobile, IBM, Coinbase, HSBC, Stanford University, Georgetown University, US Naval Academy, and the JFK Center for the Performing Arts. Revenue is generated primarily through project-based, custom-quoted contracts for turnkey stair packages, with secondary streams in railing/windscreen systems and design-assist consulting. Delivery is executed via in-house union and non-union installation crews across North America and the UK, eliminating subcontractor dependency for the most complex installations. Leadership transitioned in 2025-2026 with the appointment of Tracy Lea Neff as President and Steven Elsdon as CEO, while founder-family members Jim Admiraal (CRO) and Lee Admiraal (Director) remain involved, indicating a managed professionalization of the founder-led business. The company pursues sustainability leadership with a net-zero carbon commitment by 2030, 500-mile material sourcing, and a track record of over 80% LEED-certified projects.

The company completes over 200 successful feature stair installations annually, with projects ranging from complex custom designs to standardized prefabricated solutions for large commercial projects.
2. Railing Packages and Windscreen Systems: Sale and installation of complete railing packages including decorative ornamental metalwork, pre-engineered ThinkRail systems, and custom glass windscreens. Solutions span stainless steel, bronze, brass, copper, and aluminum materials.
3.

• VIVA Railings: VIVA Railings is a US-based fabricator and installer of architectural railings, glass, and metal systems for commercial buildings. Directly comparable to Synergi's Railing Packages & Windscreen Systems line in product scope, customer profile (commercial GCs and architects), and fabrication-plus-installation model.
• Jefferies Stair & Rail: Jefferies specializes in custom architectural stairs, railings, and ornamental metalwork for commercial projects. Closely mirrors Synergi's turnkey feature stair business, including design-assist, structural steel fabrication, and on-site installation for office, hospitality, and institutional customers.

Broad incumbents

• Oldcastle BuildingEnvelope: Oldcastle BuildingEnvelope is a large North American supplier of architectural glass, metal, and railing systems for commercial building envelopes. Comparable as a broad incumbent in metal and glass railing/windscreen systems, though at much greater scale and scope than Synergi.
