Numilk is still in business, but it looks very different from the company that walked into the Shark Tank set in 2021.
The original idea was built around machines installed inside grocery stores. Customers could use a Numilk kiosk to make fresh plant-based milk instead of buying cartons that were mostly water. The company had machines in Whole Foods and was pursuing larger retail partnerships when the COVID-19 pandemic disrupted the grocery rollout.
By the time founders Ari Tolwin and Joe Savino appeared on Shark Tank in March 2021, the business had already begun moving toward a different model: smaller machines for cafés and, eventually, a countertop machine for homes.
The pitch produced a $2 million offer from Mark Cuban. The structure mattered: $1 million for 7% equity, plus a $1 million loan at 3% interest that would give Cuban another 3% equity if the loan was used.
Numilk accepted.
Five years later, the company's own website says the business has served more than 500 cafés and that thousands of households use its home machine. It is selling machines and milk pouches directly today. (numilk.com)
That makes Numilk an unusual Shark Tank story. The original retail-kiosk thesis did not become the national grocery-store network the founders had envisioned. Instead, the company used the exposure and financing to build a smaller, more specialized plant-milk system.
Numilk went into the Tank asking for $1 million
Tolwin and Savino entered Shark Tank asking for $1 million in exchange for 5% of Numilk, implying a $20 million valuation.
The product the Sharks saw was essentially a plant-based milk vending machine. Numilk's proposition was straightforward: instead of transporting finished almond, oat or other plant milks in cartons, stores could have customers make fresh milk on site.
The Sharks liked the taste. The financial picture was harder to swallow.
Kevin O'Leary questioned the economics of the grocery-kiosk model, particularly the cost of building and maintaining machines. During the pitch, the founders said Numilk had raised $12 million and had lost roughly $7 million of it, largely through research and development spending. Those figures were part of the company's presentation to the Sharks, rather than an independently audited measure of its financial position.
The founders also showed a prototype that pointed toward a different future: a countertop machine that could make plant milk at home.
That was the product Mark Cuban focused on.
Mark Cuban offered $2 million, but it was not simply $2 million for 10%
Cuban's offer was structured in two parts.
He offered $1 million for 7% of Numilk, plus another $1 million as a loan at 3% interest. If Numilk took the loan, Cuban would receive another 3% in equity.
In other words, the headline figure was $2 million, but the investment was not a conventional $2 million equity check for a fixed 10% stake. The additional equity was connected to the loan.
The founders accepted Cuban's offer.
Numilk's own current company history describes the transaction as a $2 million deal with Cuban and identifies it as one of the company's major turning points. (numilk.com)
There is also a useful distinction between what happened on television and what happened afterward. Contemporary reporting sometimes described the transaction as a $2 million investment for 10%. The more precise description is the split structure shown above.
The pandemic helped kill the grocery-kiosk strategy
Numilk's original retail expansion was already expensive and operationally complicated. Then the pandemic hit.
The founders had been working on grocery-store expansion, including planned launches involving retailers such as Kroger and Gelson's Markets. The pandemic disrupted those plans as grocery traffic and retail operations changed.
That made the smaller machines increasingly attractive.
Numilk's current account of its history says that COVID prompted the company to pivot from grocery kiosks to countertop machines. The company says it began building the countertop machine internally and later secured a manufacturing partner to help scale production. (numilk.com)
That pivot is the key to understanding what happened after Shark Tank. Numilk did not simply take Cuban's money and expand the original kiosk network. It changed the product and, with it, the business model.
The Shark Tank appearance immediately produced $222,353 in crowdfunding
Numilk's timing was unusually effective.
The company's Kickstarter campaign for Numilk Home ran from March 25 to May 9, 2021, overlapping directly with the show's broadcast. It had a $100,000 funding goal.
It finished with $222,353 pledged by 888 backers. (kickstarter.com)
Kickstarter itself later highlighted Numilk as an example of a company that went from crowdfunding to Shark Tank. Its account confirms the $222,353 raised from 888 backers. (updates.kickstarter.com)
The campaign was more than a publicity stunt. It gave Numilk evidence that consumers were willing to pay for the smaller home version of the product, rather than merely liking the concept of fresh plant-based milk.
The company was also developing its commercial machine. In 2021, Numilk told backers it was expanding its commercial operation and announced a pilot with Blue Bottle Coffee. It also said Beatrix restaurants in Chicago were expanding their use of Numilk Pro. (numilk-home.backerkit.com)
Numilk gradually moved from supermarkets toward cafés
The most consequential change was the decline of the grocery-kiosk strategy.
Numilk's early machines were designed to sit inside stores such as Whole Foods. The newer strategy centered on Numilk Pro for cafés and commercial customers and Numilk Home for consumers.
That shift made sense operationally. A café or restaurant can use the machine repeatedly throughout the day, while Numilk can sell or supply the ingredients without requiring the consumer to understand a complicated retail installation.
The company's current website says Numilk started with a single café customer and grew to more than 100 cafés by 2022. It now claims its products are served by more than 500 cafés. (numilk.com)
Those are company-reported figures, not independently audited location counts, so they should be read that way.
Still, the direction is clear. Numilk's business today is much closer to a specialized appliance and ingredient company than to the grocery-store vending concept presented in the original pitch.
Numilk now sells a home machine and ingredient pouches
The current Numilk product is considerably more consumer-oriented than the machine shown at the start of the company's story.
The Numilk Home Machine uses pre-measured ingredient pouches. According to the company, a pouch can produce 32 ounces of plant-based milk in about 60 seconds. The current product range includes plant milks and latte-oriented products. (numilk.com)
The economics also work differently from buying a carton of almond or oat milk. Numilk sells the machine once and then sells the consumable pouches that go into it.
That recurring component is central to the model.
The company emphasizes that its pouches contain real ingredients and avoid the gums, fillers and preservatives it says are common in conventional packaged plant milks. Its current site also promotes the environmental argument that shipping concentrated ingredients rather than finished milk means shipping substantially less water. (numilk.com)
Whether every environmental claim should be treated as independently established is a separate question. They are, at this point, claims made by Numilk itself. But the underlying business logic is easier to see than it was in the original kiosk model: sell the machine, sell the ingredients, and keep the customer inside the Numilk ecosystem.
So, is Numilk still in business?
Yes.
As of August 2026, Numilk's official website is active, its online store is selling the Home Machine and pouches, and the company continues to publish new product and marketing material. Its legal terms identify the operating entity as Plant Tap, Inc., doing business as Numilk. (numilk.com)
The company says the home machine is now used by thousands of households and that Numilk is served in more than 500 cafés. (numilk.com)
What is less clear is the company's precise current financial performance.
Some secondary websites circulate large revenue, valuation and growth figures for Numilk, but those numbers are not substantiated by the company's current website or a public financial filing. They should not be treated as established facts. There is no reliable public evidence here to confidently state a current valuation or annual revenue figure.
That uncertainty is worth preserving rather than filling with an estimate.
What can be verified is more modest and more useful: Numilk survived the pivot, moved away from its original grocery-kiosk strategy, built a home product, developed a commercial business, and remains actively selling its products.
The real Numilk story is the pivot, not the $2 million headline
The most interesting part of Numilk's Shark Tank story is not that Mark Cuban wrote a $2 million deal.
It is what Numilk did when the business it had originally built stopped making sense.
The company entered the Tank with a grocery-store machine and a plan to change how consumers bought plant milk. COVID accelerated the weaknesses in that model. The founders then pushed toward countertop machines, raised another $222,353 from 888 Kickstarter backers, developed a professional product for cafés and eventually built a direct-to-consumer business around Numilk Home and its ingredient pouches. (kickstarter.com)
So whatever happened to Numilk?
It did not become the nationwide grocery-kiosk network its first pitch suggested. It became something narrower: a plant-based milk appliance and ingredient company with a commercial café business and a consumer machine that is still being sold.
For a Shark Tank company, that is a less dramatic ending than a billion-dollar exit. It is also a much more defensible one.
