Cassone

What Cassone does

Cassone Leasing Inc., operating as Cassone, is a family-owned and women-led provider of relocatable modular buildings, mobile office trailers, and storage containers founded in 1976 and headquartered in Ronkonkoma, New York. The company offers a broad product portfolio spanning modular offices (office trailers, office containers, the proprietary IBOX modular system, and premium Signature Sales Offices), specialty buildings (modular classrooms, concession stands, ticket booths, security and guard booths), storage solutions (ground-level and climate-controlled units), and custom modular buildings including modular and tiny homes. Its underlying technology relies on modular construction using shipping containers and prefabricated units, with specialized expertise in IIB non-combustible construction methods meeting NYC Building Codes, including closed-cell spray foam insulation, two-part poured epoxy flooring, FRP over moisture-resistant gypsum, and weatherproof electrical systems for demanding environments such as marine/saltwater exposure (as demonstrated by the 2025 MBI Honorable Mention New York Aquarium project).

Cassone generates revenue through four streams: rental and leasing of modular units on flexible terms from under 3 months to 12+ months with rent-to-own options (subscription recurring), outright sales of modular buildings (one-time purchase), truck and equipment sales through its Cassone Truck Sales division, and full-service custom project services covering planning, design, permitting, and installation. The company serves a diversified mix of vertical segments with construction and development, government and municipalities, and education as primary segments; security, events and entertainment, commercial and retail, and residential as secondary. Customers range from individual contractors to enterprise accounts including Skanska, Kiewit, Weeks Marine, AECOM, NYPD, NYC Parks, LIRR, Heineken, and Riverhead Charter School, with marquee infrastructure project work including the Champlain Hudson Power Express and the Gateway/Hudson Tunnel Project.

The go-to-market model is sales-led, with dedicated regional sales representatives and branch sales managers covering territories across the Tri-State area (NY, NJ, CT, PA, DE), supported by an online quote request portal and in-house delivery and installation logistics capable of 24-72 hour fulfillment on in-stock units and rapid custom build timelines (e.g., 6,000 sq. ft. delivered in 10 days, 2-day installation for the NY Aquarium project versus several months for conventional construction). The company is a certified Women's Business Enterprise (WBE), operates as a private family-owned business with no disclosed external institutional investment, and is led by President Lynn Cassone and Executive Vice President Lisa Cassone.
