What Berntsen International does

Berntsen International Inc. is a Madison, Wisconsin-based manufacturer and distributor founded in 1972 that supplies precision infrastructure marking products to surveying, utility, construction, and parks & recreation customers across all 50 U.S. states and more than 100 countries. The company produces aluminum and bronze survey markers and monuments, plastic and metal utility markers, fiberglass trail and signage products (Carsonite line), reflective survey targets, prisms, and construction accessories — many manufactured in-house using a proprietary orbital forging process that replaced traditional casting. Its InfraMarker RFID system, launched in 2012 and extended in 2025 via an Esri ArcGIS integration with Biomark, pairs RFID tagging with GIS mapping to provide digital identification and real-time location intelligence for underground utilities, infrastructure assets, and wildlife.

Berntsen operates a direct-to-customer sales model through its e-commerce website (www.berntsen.com) and a phone-based sales line, supplemented by a dedicated government sales channel with NET 30 terms, IMPAC card, and WAWF payment processing (CAGE Code 57002). Revenue is generated primarily through one-time hardware product sales, custom-manufactured markers with bespoke lettering and logos, RFID reader/tag/software packages, and government contracts. The company also distributes partner brands including Carsonite (fiberglass posts), Schonstedt (magnetic locators), Rothbucher (reflective targets), and Atlas Copco (construction tools), positioning itself as a single-source supplier for surveying and infrastructure marking professionals.

The company identifies as a privately held Small Business Corporation with 11-50 employees and no disclosed external institutional investors, parent company, or M&A activity. Customer concentration is diffuse across SMB surveying firms, government agencies, and utilities, with several 20+ year customer relationships evidencing high product stickiness. Leadership comprises founder lineage (Peter Berntsen, Phillip Peterson) alongside an operating team led by CEO Rhonda Rushing, President Mike Klonsinski, and VP of Finance & Operations Cindy Tracy.

Broad incumbents

• 3M: Manufactures reflective sheeting, pavement marking tapes, and utility locating/marking products that overlap with Berntsen's reflective markers, decals, and detectable/non-detectable marking tape.
• Trimble Inc. Dominant provider of geospatial, surveying, and infrastructure software/hardware (GNSS, total stations, GIS, asset management). Overlaps with Berntsen across survey monuments, utility mapping, and infrastructure asset workflows, though at a vastly larger scale and broader portfolio.
• Leica Geosystems (Hexagon AB): Surveying and measurement instruments including prisms, GNSS, and laser scanner targets — directly comparable to Berntsen's Rothbucher-style smart targets and survey prisms. Part of Hexagon's broader geospatial stack.
