Inergize Health

What Inergize Health does

Inergize Health is a San Diego-based direct-to-consumer company, founded in 2021 by mechanical engineer Ciaran Flanagan, that designs and sells cold plunge and hot/cold therapy systems. Its product portfolio spans three hardware tiers — the premium Spire Elite (cedar and 316 marine-grade stainless steel vertical plunge with built-in reclined seat, $7,490), the portable Inergize Cold Plunge Elite Tub (drop-stitch construction bundled with chiller, $2,990), and a standalone Elite Chiller ($2,690) for DIY or upgrade installations — plus certified refurbished units and a recurring maintenance/accessory line (filter 6-packs, descaling solution, 4-month maintenance kits). The technology platform centers on a 0.8 HP industrial chiller delivering 37–104°F in one unit, a proprietary 4-way filtration architecture (20-micron filter plus 400 mg/hr ozone output, roughly 4× competitor benchmarks) with up to six months between water changes, 2-inch closed-cell PU insulation, and Tuya Smart app + onboard touchscreen control.

The company sells exclusively through its own Shopify storefront with no retail intermediaries, supported by an affiliate program, athlete/longevity-influencer ambassador distribution, and a dedicated sales line for commercial buyers (50+ commercial locations installed). Payment and financing stack includes 0% APR installments through Affirm (up to 24 months), HSA/FSA eligibility through Truemed, and optional 3- and 5-year extended protection plans via XCover. Customer segments are horizontal, spanning pro athletes (boxing, UFC, CrossFit, MLB, PGA), biohacking/longevity enthusiasts, health-conscious home consumers, and commercial wellness facilities; the brand has been featured in Forbes, Sports Illustrated, CBS Innovation Nation, BarBend, and Garage Gym Reviews. Founded with an Indiegogo crowdfunding launch in 2022, the company is privately held and founder-controlled with a 1–10 person team operating out of a San Diego HQ and an LA repair center, having shipped 5,000+ units across 10+ countries.

Product lines include the premium Spire Elite (cedar + stainless steel with built-in reclined seat), the portable Inergize Cold Plunge: Elite Tub (drop-stitch, with bundled chiller), a standalone Elite Chiller for DIY setups, and recurring maintenance accessories and extended protection plans.

Product overview

Inergize Health offers a portfolio of cold plunge and cold therapy products for residential and commercial use. The core lineup consists of two product families: (1) the Spire Elite — a permanent-install premium cold plunge combining red cedar wood exterior with 316 marine-grade stainless steel interior, featuring a built-in reclined seat, 0.8HP industrial chiller, 4-way filtration, and integrated hot+cold therapy (37°F–104°F); and (2) the Inergize Cold Plunge: Elite Tub — a portable drop-stitch tub bundled with the Elite Chiller, offering the same filtration and temperature range in a deflatable, backpack-portable form factor. The Elite Chiller is also sold separately for DIY or upgrade installations. Supporting the product line are maintenance accessories including filter packs, descaling solutions, and maintenance kits, plus certified refurbished options. All products share a 4-way filtration architecture (strainer, 20-micron filter, ozone sanitation, air intake filter), Tuya Smart app control, and HSA/FSA purchasing eligibility. The company sells direct-to-consumer with US-based customer support in San Diego.
