What 605 Companies does

605 Companies, Inc. is a privately held, founder-owned sitework construction and general contracting firm headquartered in Sioux Falls, South Dakota. Founded in 2014 by Matt Kissell (previously of Kissell Construction, est. 2012), the company operates a seven-service-line integrated portfolio: Sitework Services, Underground Utilities, Mobile Concrete and Asphalt Crushing, General Contracting, Welding and Repair, Trucking and Hauling, and Erosion Control and Hydroseeding. The underlying technology base is physical-heavy — fleet vehicles, mobile crushing equipment, and excavation machinery — rather than software-defined; the mobile crushing capability is the most differentiated technical asset, processing on-site demolition debris into reusable aggregate (12,000 tons quantified) and creating internal cost economics on materials.

The company serves four customer verticals — municipal/government, commercial, agricultural, and residential — across Eastern South Dakota, Northwest Iowa, and Southwest Minnesota, with active project work visible as far as Crofton, NE. Go-to-market is direct-sales-led: prospective customers contact an estimating desk via phone ((605) 251-3185) or email ([email protected]) for quote-based project bids, supported by organic social marketing on Facebook, Instagram, and LinkedIn. Revenue mechanics are entirely project-based and one-time per engagement (no disclosed recurring contracts or SaaS-like pricing), with services rendered on-site at customer locations.

The business is bootstrapped and founder-controlled with no disclosed institutional ownership, no parent company, no M&A history, no patents or trademarks, and no formal awards or compliance certifications in the input data. Leadership is lean — President Matt Kissell plus Project Managers Zachary Dinger (civil heavy highway) and Brice Gilley (commercial contracting) — with 11-50 total employees. The company emphasizes relationship-driven repeat work and licensed/bonded/insured status as commercial credentials in lieu of formal certifications or branded IP.
