Lessen is the intelligent operating platform for property services, combining purpose-built software, embedded intelligence, proprietary data, operational expertise, and a nationwide vendor network to help commercial and residential property owners and operators execute maintenance, repairs, and capital programs with greater consistency, control, and cost discipline across distributed portfolios. Rather than simply connecting property owners with service providers, Lessen orchestrates the full lifecycle of property services execution; from intake and vendor dispatch through completion, billing, and performance governance. This is powered by 20 years of operating history, 40M+ cumulative work orders, and a credentialed network of 30,000+ vendors serving 300,000+ properties across 100+ metro areas nationwide. Lessen's platform includes ONE by Lessen, the managed-services execution model for operators who want Lessen to run programs end-to-end; Lessen360, the self-managed platform for operators who want to retain direct operational control; LessenPro, the field service management platform for independent trade contractors and trade businesses; and Lessen Marketplace, a procurement platform that turns Lessen's scale into vendor buying power. Aiden, Lessen's embedded intelligence layer, operates across each of these platform, improving execution based on real operational data, not generic automation. Lessen was formerly known as SMS Assist.
