What Hudson Aquatic Systems does

Hudson Aquatic Systems is a privately held US manufacturer of specialized aquatic therapy equipment, operating from a 40,000 sq. ft. facility in Angola, Indiana. The company designs, engineers, and manufactures underwater treadmill systems and custom therapy pools serving three distinct end markets: canine rehabilitation (AquaPaws series), equine therapy and performance conditioning (AquaPacer series), and human physical therapy and sports medicine (AquaFit, AquaGaiter, AquaCiser, plus Performance & Therapy Pools). Underlying technology combines an enclosed treadmill unit with an integrated water management system — filtration, UV sterilization, ozone sanitization, and chemical balancing — engineered specifically for the hair, dander, and bioburden characteristics of animal therapy. Notable proprietary features include lateral stability support for equine systems, adjustable water depths up to 47 inches, dual-tank warm/cold saltwater configurations on the Platinum equine model, and gait-analysis cameras with programmable protocols on the canine SS model.

The business operates a B2B direct-sales motion targeting veterinary clinics, equine training facilities, physical therapy practices, hospitals, military K9 installations, and veterinary and PT teaching institutions (including UC Davis, Purdue, Colorado State, and 24+ other teaching hospitals). Revenue is generated through five streams: (1) one-time hardware sales of new treadmill systems and custom pools (quote-based, not publicly disclosed), (2) the Rehab Ready Leasing Program offering 36-month leases with full warranty — a first for Hudson and a recurring revenue lever, (3) service, maintenance, and lifetime technical support contracts including the Ask SAM program, (4) the AquaStore e-commerce channel for accessories, chemicals, and consumables ($1-$1,500+ per item), and (5) custom design, engineering, and installation services. Distribution is direct domestically, supported by an inside sales team, an event-driven demand-gen presence at AVMA, AAEP, WVC, APTA CSM, NATA, and ASHE conferences, and an exclusive international distribution partnership with Changzhou Qianjing Rehabilitation Company for China. Hudson carries a multi-generational corporate lineage (Ille Electric Corporation in the 1920s, Beatrice Foods, Market Forge, Ferno Washington from 1983, and The Ellis Company from 2010), with no outside institutional investors and no disclosed cap table.

Revenue model

1. Underwater Treadmill Equipment Sales: Hudson sells underwater treadmill systems (canine, equine, and human models) as the primary revenue stream. Equipment includes the AquaPaws, AquaPacer, AquaFit, and AquaGaiter product lines, with prices varying by model and configuration. Refurbished/trade-in units are also sold at reduced prices ($31,000+ for used AquaPaws SS).
2. Equipment Leasing (Rehab Ready Leasing Program): A dedicated leasing program offering 36-month term leases on Hudson underwater treadmills with low monthly payments, full warranty coverage, and protection. This lowers the capital barrier for facilities to acquire equipment, creating a recurring revenue stream.
3. Service, Maintenance, and Support Contracts: Annual maintenance contracts, on-site service visits, and 24/7 technical support services. The Ask SAM program provides ongoing water quality and maintenance support for the lifetime of the unit. Remote diagnostics and preventative maintenance programs are also offered.
4. Accessories and Consumables (AquaStore): Online retail store selling accessories, maintenance supplies, and consumables including water treatment chemicals, Magic Lube lubricant, entry steps, technician benches, TreadRails, AquaFill autofill systems, floatation devices, and cleaning kits. Prices range from $1 to $1,500+.
5. Custom Build and Installation Services: Custom design, engineering, installation, and on-site training services. Comprehensive sale-to-service process including custom design, in-house testing, assembly, installation, and round-the-clock service support. Training covers equipment operation, safety protocols, and therapeutic application.
