Rice Spinout NIVERA Lands Over $600,000 to Triple Produce Shelf Life

NIVERA, a startup founded by Rice University doctoral alumna Neethu Pottackal, has secured more than $605,000 in early-stage funding — a $305,000 Phase I Small Business Innovation Research award from the National Science Foundation plus an Activate Fellowship worth over $300,000 — to commercialize an edible coating the company says can nearly triple the shelf life of certain fruits and vegetables.

That shelf-life claim comes from the company's own testing, and the source offers no third-party validation. The figure anchors the company's pitch nonetheless: a thin, plant-based barrier applied to fresh produce to slow the biological processes — moisture loss, gas exchange, microbial growth — that begin the moment a crop is harvested.

"Anybody who's bought a box of strawberries or an avocado can relate to it going bad before they can even eat it," Pottackal said. "But it's more than just an inconvenience. It points to a massive problem of food waste as well as access to fresh food."

The scale of that problem is not in dispute. According to the United Nations Environment Programme, more than a billion metric tons of food are wasted globally each year — roughly a ton of waste for every eight people on the planet, much of it before produce ever reaches a consumer.

What does the coating actually do?

NIVERA's coating is made from naturally derived ingredients, including proteins and fibers, and some of those materials come from agricultural by-products. The company frames this as a two-sided benefit: lower production costs and a productive use for existing waste streams. No cost figures or production volumes appear in the source material.

Technically, the coating works through a plant-based matrix that provides structure, combined with other natural components that add mechanical stability and antimicrobial properties. It targets three spoilage drivers at once: moisture loss, oxidation and microbial growth.

"Working at the intersection of materials science and mechanical engineering, we're able to approach this problem from different perspectives," Pottackal said. "We're looking at not only the materials but how they interact with each other."

The science grew out of her doctoral work at Rice, co-advised by Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Daniel Preston, assistant professor of mechanical engineering. Ajayan's lab guided the coating's formulation; Preston's lab contributed spray-coating expertise and the work of translating lab results into practical technology. Preston's lab is now a subawardee on the NSF grant — a notable alignment between the founder's company and her former adviser's research group.

Where is the money going?

NIVERA is targeting high-value produce first: avocados and berries, where longer shelf life carries clear economic upside. Testing with avocados, the company says, has already shown significant shelf-life gains — again, without published independent figures.

"We're targeting keeping fruits and vegetables fresher for longer so that they can last all the way from harvest to packaging, transit and supermarket shelves before the consumer can finally purchase and consume them," Preston said.

The startup's institutional backing extends beyond federal funding. Pottackal was selected for the 2026 Activate Fellowship, which supports scientists commercializing hard technology. Earlier, Rice's entrepreneurship ecosystem helped her cross from research to business: she completed the Liu Idea Lab's Innovation Fellows program and the Rice Venture Scholars initiative, won a $25,000 prize at the Napier Rice Launch Challenge, and reached the semifinals of the Rice Business Plan Competition, where she won Overall Best Elevator Pitch and the $25,000 Energy, Cleantech & Sustainability Prize. Combined, her competition winnings add another $50,000 to the company's early capital.

"Rice has played a big role in shaping me, not just as a researcher but also as a startup founder," Pottackal said.

Preston points to NIVERA as proof of a broader trend. "The innovation and entrepreneurship ecosystem here at Rice is booming right now," he said. "There are massive opportunities for students to translate their impactful research in the lab to real-world use and implementation."

What comes next?

The open question is scale. NIVERA must now show its coatings deliver consistent performance and economic value outside the laboratory — the gap where many food-tech coatings have stalled before. Pottackal acknowledges the path has not been straight: "I'm really proud of how far we've come, and a founder's journey is not always linear," she said, adding that she plans to hire more engineers and scientists to work on "improving sustainability and reducing waste at the food-water-energy nexus."

In plain terms: the funding buys NIVERA a real shot at proving its coating works at commercial scale. Whether it does remains the part no grant can guarantee.
