Cosand Construction Company, LLC

What Cosand Construction Company, LLC does

Cosand Construction Company, LLC is a family-owned general contractor and carpentry subcontractor headquartered in Sioux Falls, South Dakota, founded in 2013 by Kyle Cosand and co-led with Brooke Cosand. The firm operates four service divisions: General Contracting (project coordination and subcontractor management for commercial and residential builds), Subcontracting (rough carpentry, finish carpentry, commercial door installation, wall protection, and ADA-compliant specialties), Service (repairs, remodels, and warranty work), and Production (in-house fabrication of custom casework, architectural features, stairs, and tables via a CNC-equipped carpentry shop). Project scopes range from boutique hospitality conversions and multi-story mixed-use developments (e.g., Hotel on Phillips, Cherapa Place Building II) to small-business tenant improvements (Human Bean, Atomic Wings, Flourish Birth Co).

Revenue mechanics are entirely project-based and quote-driven. Pricing flows from per-square-foot estimates generated by an in-house web Cost Calculator, with example outputs in the $195-$245 per square foot range for new office construction; subcontractor scopes are negotiated bilaterally. The go-to-market is sales-led and dual-pronged: direct-to-consumer engagement (website, phone, contact form, calculator) and channel partnerships with two regional general contractors — Journey Construction and Henry Carlson Construction — which deliver larger commercial flow. The company is privately held, with no institutional investors, parent company, or external funding disclosed, and operating geographies are limited to the Sioux Falls region.

The operating footprint is small — nine employees per firmographic data, though approximately 18 named personnel appear on the team page across management, operations, and field roles — supporting an estimated annual revenue in the single-digit millions of dollars. There are no AI/ML products, patents, certifications, or external capital raises on record; strategic differentiation rests on craft expertise, an in-house CNC production capability, durable subcontractor relationships, and a diversified portfolio of repeat and one-off clients across commercial, institutional, and SMB segments.
