Grüns founder Chad Janis on building a $1.2B gummy supplement brand in 3.5 years and selling to Unilever

Grüns: $1.2B exit, 3.5 years, $50M raised

Chad Janis built Grüns from a dorm-room idea into a $1.2B Unilever acquisition in roughly three and a half years, raising only ~$50M along the way. The math alone makes it one of the more capital-efficient exits in recent DTC history.

Origin and category thesis

The idea came two weeks before Janis started at Stanford Business School. He was drinking a greens powder, looked up, and thought he wouldn't keep the habit past 30 days. The question he set out to answer was how to take a comprehensive nutritional blend and put it into a form factor that consumers would actually look forward to — something they'd go to bed thinking about.

He spent roughly a year formulating before launching in August 2023. About a quarter of his Stanford class tried early iterations. Nineteen out of 20 co-manufacturers he called told him the idea wouldn't work and would taste disgusting. One agreed to try.

Janis frames Grüns as a third generation of the gummy category. Ollie, founded around 2014, made gummies approachable. Grüns' pitch is that the category is now mature enough to carry genuinely robust, comprehensive blends — not single trending ingredients that rise and fall with the news cycle, which he views as Goli's vulnerability.

“We ship 10,000,000 gummies a day and have the infrastructure for it... We raised probably around $50,000,000 over the course of the business... The hardest part about building this business is the little pack that we have — that infrastructure for taking gummies and putting it into packs did not exist prior to us. For the first six to eight months, we had 20 bodies standing around a table manually picking up gummies and putting them in packs.”

The supply chain constraint nobody saw coming

The hardest operational problem wasn't the product itself. The packaging infrastructure for putting gummies into individual daily packs simply didn't exist. For the first six to eight months, Grüns had 20 people standing around a table manually picking gummies and placing them into packs, sealing each one with what Janis describes as a clamp sealer that looked like a staple gun.

That bottleneck defined the company's early risk profile. Six months in, on January 29, Janis had to cut marketing spend by 93% overnight after a co-manufacturer reassured him for two weeks that inventory was fine — then confirmed it wasn't. The company's rule since then has been absolute: Grüns does not go out of stock. If meeting that means shutting off customer acquisition entirely, that's the trade.

Today the operation ships 10 million gummies a day across multiple co-manufacturers, co-packers, 3PL nodes, and an in-house facility.

Growth drivers

Janis cites three factors behind the company's trajectory. First, each product launch enters a space where a direct equivalent doesn't exist — Grüns creates categories rather than competing inside them. Second, compounding daily urgency across the team. Third, the 130-person team structured around what he calls a "CEO of your domain" culture, where individuals own their function with full autonomy and accountability.

One early unconventional hire: a Chief People Officer well before most companies at that stage would consider it. Janis's rationale is that culture is the underlying mechanism of frictionless growth, and that getting the right people into the right environment early determines the ceiling.

Retail sequencing

Janis says he always intended Grüns to be omnichannel — no pride in being purely DTC. He started retail conversations in January 2024 despite pushback that it was too early, betting that the selling cycles were long enough that waiting would cost more than moving. The sequence: Sprouts in October 2024, Target in February 2025, Walmart in April 2025.

The biggest unlock for retail readiness was a rebrand. The original packaging, developed in Canva in an afternoon, was dark green and hard to parse quickly. The redesign made the product identifiable within three seconds on shelf.

Brand positioning

Janis looked at Dr. Squatch as a reference point — a brand that made an everyday routine feel like an experience worth having. Grüns applies that logic to supplements: clinical studies exist and are done, but leaning on them is what every other brand in the category does. The positioning is lifestyle-led, with the goal that consumers associate the brand with who they are, not just what it does for them.

Unilever rationale

Janis started informal conversations with Unilever around June before the deal closed. His pitch for why Unilever specifically makes sense as an acquirer rests on their track record with comparable acquisitions: Nutrafol (significantly larger than at acquisition), Liquid I.V. (acquired ~2020, reported ~$1B in revenue last year), and Ollie (acquired 2019, significantly larger). His read is that Unilever understands the operational path from DTC-native brand to scaled omnichannel business better than most strategics.

AI use

Grüns runs on Claude across teams, with the internal framing that everyone should be able to make their own role replaceable. The enabler is a clean data warehouse that gives every function — CX, finance, marketing — a single source of truth to query. Creative, however, remains almost entirely human-generated. Janis is cautious about AI-generated content for a brand that needs to project credibility, so UGC and influencer content still dominate the ad stack.

Meta remains the dominant paid channel, though Janis flags that brands running 85–90% of spend through Meta alone are underexposed to channel diversification — Grüns has deliberately built beyond that.

Janis nearly didn't graduate. Two weeks before finishing, he told his wife there was a real chance he'd miss the GPA cutoff, with the business already doing $50M in revenue and roughly six people on staff. He graduated. The Unilever deal closed shortly after.
