He studied law at NYU. He now argues, mostly, about diaper absorbency. As co-founder and CEO of Freestyle, he is rebuilding the most boring aisle in the store.
Most people meet Russ Wallace and expect a pitch. What they get is a spreadsheet, a shipping timeline, and an opinion about tree pulp.
Wallace runs Freestyle, the Santa Monica baby-care brand he co-founded in 2022 with Mike Constantiner. The premise is deceptively simple: the diaper aisle was built for a version of parenting that no longer exists, and nobody bothered to update it. Freestyle's answer is a tree-free diaper built on a bamboo core, lab-tested to absorb up to 14 times the leading brand, and marketed as if parents are actual adults rather than a focus group.
The résumé behind that bet is not the one you would guess. Wallace holds a JD and an LLM from New York University School of Law. He could have spent his career billing hours. Instead he went into consumer packaged goods, landing at Hello Bello, the brand that dragged premium baby care into the mass market. As Head of Business Development he helped push the company past a $100 million run rate, learning the unglamorous mechanics of getting a physical product made, boxed, and onto a shelf on time.
That is the part that matters. Plenty of founders can describe a better diaper. Wallace can actually manufacture one. His co-founder puts it plainly.
The introduction that started it all was almost bureaucratic. A mutual friend connected two Santa Monica dads on the theory that they both worked in CPG and both had kids. The theory held. Wallace and Constantiner found they could talk for hours about how their generation was rebuilding family life from scratch: reconsidering where to raise kids, what to feed them, and which of their own childhood assumptions to quietly retire. Somewhere in those conversations, a company appeared.
The ProductFreestyle's flagship diaper leads with a claim, not a mascot. Its Skin Shield technology has been independently lab-tested to deliver up to 14 times the absorbency of leading brands, wrapped in a seven-layer, patent-pending design. The core is bamboo, not wood pulp, which is the tidy version of a longer argument Wallace is happy to have: the standard disposable diaper is an environmental liability that parents were never really offered an alternative to.
Comparison per Freestyle's stated product claims, based on independent lab testing.
Just as pointed is the marketing. The baby aisle has, for decades, addressed exactly one parent. Freestyle's branding refuses to default to mom. It talks to dads too, to co-parents, to whoever is actually up at 3 a.m. It is a small reframing that turned out to be a large market. Since launching online in 2022, Freestyle has grown roughly 400% year over year and built a promotional machine powered by more than 1,000 creators and influencers, which is a strange sentence to write about diapers and exactly the point.
Ask Wallace what a business is and he will not reach for a mission statement. He calls it, flatly, a cash-generating machine. It is the kind of line that makes venture Twitter wince and quietly nod. In an era that celebrates funding rounds and follower counts, Wallace keeps steering back to two unfashionable numbers: revenue, and the path to profit.
That instinct is why the $10 million Series A, led by Silas Capital in March 2026 with ECP Growth, Mucker Capital, Adapt Ventures, and Superangel along for the ride, reads less like a coronation and more like fuel. The interesting part of Freestyle was never the raise. It was that a bamboo diaper from two dads had already muscled its way onto the same shelves as brands a thousand times its size.
There is a lighter side to the ambition. Asked about his aspiration, Wallace did not name a technology titan. He named Jimmy Buffett. The singer who turned margaritas into a lifestyle empire, he argued, cracked the code most founders never do: build something durable, joyful, and quietly enormous. "Jimmy Buffett 2.0" is a punchline, but it is also, if you squint, a strategy.
The through-line from Hello Bello to Freestyle is not a product category. It is a temperament. Wallace is restless by nature, drawn to new subjects and far-off places, more comfortable in motion than at rest. He credits the partnership with Constantiner for the rest, the way a good co-founder covers your blind spots and corrects your worst instincts before they become decisions. Range plus a foil, applied to a category everyone else found too dull to fix.
The ArcHe holds a JD and an LLM from NYU Law, and now spends his days thinking about how much liquid a bamboo core can hold.
His stated role model is Jimmy Buffett. Not a founder, not a fund - a man who sold a feeling.
His co-founder built Cameo before this. Two very different products; one shared taste for making things people actually use.
Freestyle diapers are tree-free by design - the environmental argument is baked into the product, not bolted onto the ad.
He posts as @rustysf. The handle is older than the diaper company.
