Loliware did not disappear after taking $600,000 from Mark Cuban and Barbara Corcoran on Shark Tank. It changed the business.
When Chelsea Briganti and Leigh Ann Tucker appeared on Season 7 in 2015, Loliware was selling edible, biodegradable cups. The company had generated $110,000 in sales in its first three months, and the founders told the Sharks that the cups cost about $0.97 to produce and sold wholesale for $1.50. They were seeking $150,000 for 10% of the company, according to contemporaneous coverage of the pitch. (imdb.com)
The pitch turned into a bidding contest. Robert Herjavec proposed $600,000 for 25%, Mark Cuban joined the offer, and Barbara Corcoran also wanted in. Briganti and Tucker ultimately accepted $600,000 for 25% from Cuban and Corcoran. A contemporaneous announcement from Loliware's law firm confirmed that Cuban and Corcoran had agreed to fund the company. (prnewswire.com)
But the Loliware that exists today is not primarily an edible-cup company.
It is a materials technology company built around seaweed-derived resins.
Loliware eventually moved beyond the edible-cup idea
The original product was deliberately unusual. Loliware's cups could be eaten after use or composted, an approach the founders described as "biodegr(edible)." The concept had emerged from Briganti and Tucker's work in product design and an earlier Jell-O-related design competition. (sce.parsons.edu)
The commercial problem was that an edible cup is still a fairly specialized product.
Loliware began moving toward a broader proposition: instead of convincing consumers to replace a plastic cup with an edible one, could the company develop a material that manufacturers could use to make many different disposable products?
That became SEA Technology.
The company developed seaweed-derived resin pellets designed to work with existing plastic-manufacturing equipment. Loliware said the material could be processed using conventional equipment rather than requiring manufacturers to build entirely new factories or production lines. (loliware.com)
That was a much bigger business proposition than selling novelty cups.
The company raised millions after Shark Tank
The Shark Tank investment was only an early part of Loliware's financing story.
In February 2023, Loliware announced that it had raised another $6 million in a pre-Series A round, bringing the company's stated total funding at that point to $15.4 million. Investors named by the company included L Catterton, Alumni Ventures Group, CityRock Venture Partners, Geekdom Fund and others. (loliware.com)
That figure is worth separating from the frequently repeated Shark Tank numbers.
The $600,000 television deal was a 25% investment. The later $15.4 million figure represents the company's broader financing history, not money supplied by Cuban and Corcoran.
Loliware said the 2023 funding would support research and development, new seaweed resins and continued growth in the seaweed materials market. Its pitch had effectively evolved from "here is an edible cup" to "here is a material that could replace petroleum-based plastic across multiple applications." (loliware.com)
Straws became the proof that the new model could work
Loliware's first major application of its seaweed technology was the drinking straw.
The company partnered with plastics manufacturer Sinclair & Rush to produce its seaweed straws using the same type of equipment traditionally used for plastic straws. Loliware said the partnership demonstrated that its material could be manufactured at scale without completely rebuilding the production process. (loliware.com)
That distinction matters.
Many alternative-material companies can produce an environmentally attractive prototype. The harder question is whether a manufacturer can actually make the replacement product at commercial volumes and whether customers will buy it at an acceptable price.
Loliware's strategy was to attack that second problem through existing manufacturing infrastructure.
By 2023, the company was also selling seaweed-based utensils and working with hospitality customers. Loliware said 1 Hotels had replaced its previous PHA-based straws with Loliware straws across its 16 North American properties. (loliware.com)
Then came another recognizable customer.
In May 2023, the José Andrés Group partnered with Loliware to transition its restaurants to seaweed straws. WTOP reported that Loliware's straws and utensils were produced at a Missouri facility and that the company said the products could compost completely within 50 days. (wtop.com)
Those partnerships are considerably more meaningful than a list of celebrity endorsements. They show where Loliware was trying to build its business: institutional and commercial customers rather than primarily individual consumers buying an edible cup.
Loliware now sells the material, not just the finished novelty product
Loliware's current website makes the pivot unusually clear.
The company's central proposition is now its patented SEA Technology resins, which it makes available for licensing. It describes the resins as being made from ocean-farmed seaweed and positions them as a replacement for petroleum-based plastic. Its current product lineup includes the Blue Carbon Straw and other products made using its seaweed materials. (loliware.com)
The company also describes the straw as fully commercialized and says it has been verified plastic-free under Oceanic Global's Blue Standard. Its FAQ states that Loliware is certified 100% bio-based under ASTM D6866-21 Method B and says its seaweed is ocean-farmed rather than harvested from sensitive coastal ecosystems. (loliware.com)
The business therefore looks very different from the one that walked into the Shark Tank studio.
The edible cup was a consumer-facing demonstration of the idea. SEA Technology is the underlying materials business.
What happened to Leigh Ann Tucker?
The other major change was inside the founding team.
Loliware's current public materials identify Sea F. Briganti as founder and CEO, while current company descriptions no longer present Leigh Ann Tucker as a co-founder or executive. LinkedIn likewise identifies Briganti as Loliware's founder and CEO. (crunchbase.com)
The change is significant because much of the company's Shark Tank story was originally built around Briganti and Tucker as a two-person founding team.
The company that survived the transition is now centered on Briganti's materials-technology strategy.
So, is Loliware still in business in 2026?
The evidence says yes, although its current scale is harder to establish with confidence.
Loliware's website is active and currently promotes SEA Technology licensing, commercialized straws and seaweed-based products. Its FAQ and product pages remain live, and the company's public profile continues to describe it as a San Francisco-based private company developing seaweed-derived materials. (loliware.com)
There is also evidence of activity beyond the company's own website. A 2025 industry review reported that Loliware raised an undisclosed round during 2025 and announced a partnership with resin distributor and compounder Entec. (phyconomy.substack.com)
Loliware's founder has also publicly listed a 2025 expansion of Sea Technology into Central America, beginning in Guatemala in collaboration with the Subnational Climate Fund. (linkedin.com)
What is not clear from reliable public sources is the company's current revenue, valuation or profitability.
Some Shark Tank update sites publish precise estimates for Loliware's "net worth" or annual revenue, but those figures are not supported by equivalent disclosures from Loliware itself. One commercial database, for example, lists $6 million in 2023 revenue, while other databases provide different funding and revenue figures. (cbinsights.com)
There is no good reason to turn those estimates into a definitive 2026 valuation.
What can be established is more interesting anyway.
Loliware took a $600,000 Shark Tank deal in 2015, raised substantially more private capital afterward, abandoned the idea that edible cups would be the whole business, and developed a seaweed-based materials platform aimed at manufacturers. Its current site is still selling that proposition and seeking licensing partners.
The company did not become the household consumer brand its original Shark Tank pitch might have suggested.
It became something more specialized: a bet that seaweed can move from an unusual ingredient in an edible cup to an industrial material capable of replacing some of the plastic products manufacturers already know how to make.
That bet is still being built.
