Plunge is a hardware company that manufactures and sells at-home cold plunge devices. Founded in 2020 by Ryan Duey and Michael after their brick-and-mortar float therapy and sauna businesses were impacted by COVID, the company grew from $270k in first-year revenue to $120M+ ARR in four years. Their success is driven by influencer gifting, organic word-of-mouth, and highly efficient paid advertising (7-10x ROAS on Facebook and Google).

First customers: Direct outreach to influencers; they delivered a homemade cold plunge to Aubrey Marcus for free, who then referred Andrew Huberman and other influencers.

Narcine is a hardware startup building micro-electric vehicles for urban commuting, founded by Bulgarian industrial engineer Ognyan Bozhilov in 2016. Starting as a side project with cardboard prototypes, the team iterated through multiple designs over three years, eventually settling on a two-wheel configuration after abandoning an initial three-wheel model. They gained traction through live test-drive events and early adopters, planning to launch an Indiegogo campaign to validate the business model and scale production.

Forever Labs is a Y Combinator-backed longevity company that stores patients' stem cells via a 15-minute outpatient bone marrow aspiration procedure for $2,500 upfront plus $250/year in storage fees (or $7,000 lifetime). Founded in 2015 by Steven Klausenitzer and Dr. Mark Katakowski, the company has nearly 200 paying customers across nine states with credentialed physicians from top universities (Harvard, Stanford, Yale, etc.), generating ~$45k/month in recurring revenue from storage fees and referrals.

Light Phone is a hardware startup founded in 2014 by designers Kai Tang and Joe Hollier that creates simple mobile phones without apps or personal data tracking. The product was built in response to concerns about excessive smartphone usage and has been adopted by users across generations. The company represents an alternative movement toward a less-connected digital future.

Jamie Siminoff built Ring, a WiFi-enabled smart doorbell with a camera, starting from a personal problem he couldn't hear his doorbell. The company grew to $480 million in revenue by 2017 with triple-digit growth rates, despite being cash-flow negative due to rapid scaling. After nearly losing the deal to Amazon due to an ADT lawsuit injunction, Siminoff settled the suit, and Amazon acquired Ring for $1.15 billion in December 2017, just weeks after the legal cloud lifted.

HOKA was founded in 2007 by two French mountain athletes, Jean-Luc Diard and Nicolas Mermoud, who identified a problem with downhill running injury that major footwear brands ignored. They designed a revolutionary shoe with a rocker shape, larger volume, and softer cushioning that initially looked like clown shoes but proved transformative for ultramarathon runners. Through relentless demo-ing and getting elite runners to experience the product firsthand, HOKA grew from under $3M in sales in 2012 to over $2B annually, eventually partnering with Deckers to unlock the U.S. market.

First customers: Elite runners, through relentless demo-ing and getting people to try the prototypes

Hydro Flask was born when Travis Rosbach couldn't find a water bottle that met his needs—one that was durable, leak-proof, and kept drinks cold. He bootstrapped the company by manufacturing in China, selling at farmer's markets, and eventually securing shelf space at Whole Foods through timing and persistence. The company grew to become one of the most recognizable water bottle brands in America, fueled by word-of-mouth and retail partnerships.

First customers: Farmer's markets and outdoor markets

Big Ass Fans started in 1999 with founder Kerry Smith manufacturing and selling large-diameter ceiling fans (6-24 feet) for industrial spaces. Despite expecting to sell 1,000 fans in the first year, they sold only 142—but received positive customer feedback that gave Kerry faith to continue. Over 19 years of bootstrapped growth, relentless R&D investment, and a focus on direct customer relationships, the company built an 80% market share and sold for $500 million in 2017, with Kerry distributing $50 million in proceeds to 150+ employees.

First customers: Direct sales by founder; Kerry personally sold and occasionally helped install the first fans

Alienware was founded in the mid-1990s by Nelson Gonzalez and cofounders as a custom gaming PC shop in Miami, targeting a largely underserved market of gamers willing to pay premium prices for high-performance machines.
