What SMS Assist does
SMS Assist, doing business as Lessen Inc., is a private U.S. property-maintenance management company founded in 1995 and headquartered in Scottsdale, Arizona, with a regional office in Chicago. The company operates a technology-enabled platform that connects commercial and residential property owners and managers with a nationwide network of more than 30,000 vetted service vendors across 100+ U.S. metro areas, completing over 3 million work orders annually across approximately 280,000 properties.
The core product is One by Lessen, a cloud-based platform that manages the full maintenance lifecycle — from work-order creation and vendor sourcing through job completion and invoicing — supplemented by role-specific mobile applications for residential tenants, property managers, and vendors. Layered onto this platform are Lessen 360 (multifamily maintenance), Lessen Pro (business operations), Lessen Marketplace (discounted procurement), Homepilot (consumer-facing home services), and Aiden (an AI-driven work-order creation and management system launched in October 2025). Aiden applies generative AI and process automation to text-based maintenance requests, with knowledge retrieval used to match work orders to qualified vendors.
Lessen generates revenue through managed-services fees on property repair, maintenance, capital-project, turn, and make-ready work delivered to commercial occupiers/owners and residential property managers. Pricing is quote-based and tailored per client, with multi-year enterprise contracts. Go-to-market combines direct enterprise field sales with a two-sided affiliate/vendor channel; customer segments span eight named commercial verticals (retail, financial services, healthcare, food service, industrial distribution, hotels, telecom, K-12 education) plus single-family and multifamily residential. The company has raised approximately $255M in disclosed venture funding since 2011, with the most recent round a $150M Goldman Sachs-led investment in June 2016.
