Janesville, WI
Janesville, WI is one of the largest US markets, with 65,813 residents and a median household income of $72K. At the 96th percentile of US cities by population, the local services economy here is wide and deep — every vertical we track has 100+ active operators, and the long tail of single-truck contractors is several hundred deep.

How Janesville's demographics shape the local-services market
The median home in Janesville is worth $210K, 34% below the US median of $320K. Affordable housing stock tightens per-job margins and rewards operators with lean fulfillment. Agency campaigns lean on recurring-revenue programs and referral engines rather than premium one-off work.
With 65,813 residents, Janesville ranks at the 96th percentile of US cities by population. Large metros reward narrow books of business — a single-vertical, single-metro agency can fill a calendar without ever crossing category lines. The tradeoff is crowded messaging; a sharp differentiator beats a broad promise in every pitch motion.
