Neumann Companies

What Neumann Companies does

Neumann Companies is a privately held, family-owned holding company founded in 1979 by Mark Neumann and headquartered in Pewaukee, Wisconsin. The group operates seven subsidiaries spanning four distinct verticals: residential real estate development (Neumann Developments), home building across affordable, semi-custom, and luxury price points (Harbor Homes, Halen Homes, Tim O'Brien Homes), basement renovation services (Renova), renewable energy development (SunVest Solar), and general aviation services (Wisconsin Aviation). Across the real estate footprint, Neumann has delivered more than 6,000 homesites on 6,500 acres in over 50 Wisconsin municipalities, while preserving more than 3,000 acres of green space through community master planning.

SunVest Solar functions as an independent power producer owning many of the assets it develops and selling power and capacity to utilities, businesses, and homeowners across North America, with a current 1.5 GW pipeline expected to expand to 3 GW in 2025, ranking it among the top 10 US solar developers. The home building portfolio is differentiated by sustainability positioning, including Wisconsin's first Net Zero community at Red Fox Crossing and green building as a core (not upgraded) feature at Tim O'Brien Homes.

The company makes money through one-time home and homesite sales, professional services revenue from renovation and aviation engagements, and project-based plus recurring solar power sales. Go-to-market is sales-led and direct across all subsidiaries, with model homes, sales centers, utility offtake contracts, and on-airport FBO operations as the primary channels. Leadership is now in the second generation, with Matt Neumann serving as Chairman and CEO. The group operates exclusively as a family-owned entity with no disclosed external institutional investors or parent company.
