H&M wants to make clothing from CO2 using this startup’s tech

The fashion industry knows it has a waste problem. About one garbage truck of textiles is thrown away every second. Meanwhile, the industry generates more carbon pollution than international flights and maritime shipping combined. 

Some companies are experimenting with new ways to recycle textile waste, while others are developing new materials that won’t require fossil fuels. One startup, Rubi, is “basically taking the machinery of biology outside of the cell” to make the building blocks of lyocell and viscose, co-founder and CEO Neeka Mashouf told TechCrunch. The startup’s technology would allow any company that uses cellulose to build products from captured carbon dioxide.

Rubi recently raised $7.5 million to build a demonstration scale of its cellulosic production system, which is designed to produce tens of tons of material using CO2 as its main ingredient. The round was led by AP Ventures and FH One Investments, with participation from CMPC Ventures, H&M Group, Talis Capital, and Understorey Ventures, Rubi exclusively told TechCrunch.

The startup has booked more than $60 million in non-binding off-take agreements with a couple of partners, Mashouf told TechCrunch. The company has tested the material with 15 pilot partners, including H&M, Patagonia, and Walmart.

To make cellulose for lyocell or viscose, Rubi uses enzymes. That differs from other startups, which might use engineered bacteria inside a fermenter or chemical catalysts to transform carbon dioxide into the compound. Today, most cellulose comes from trees, including plantations and virgin rainforests.

“These textile and raw material supply chains are very long,” Mashouf said. “Here in the U.S., we’ve gotten interest in being able to actually produce cellulose pulp that’s textile-grade, where that doesn’t exist today.”

The idea to use enzymes came when Mashouf, who as a scientist researched new materials, teamed up with her twin sister, Leila, who was studying medicine at Harvard Medical School. “We looked at all the tech out there,” she said, but they kept coming back to enzymes.

The enzyme industry is massive, she said. It’s used to make high-fructose corn syrup and in wastewater treatment. “The capacity is out there already and can be very low cost.”

Rubi uses a “cascade” of enzymes to process waste carbon dioxide. The company has used AI and machine learning methods to boost the enzymes’ efficacy and stability. 

Currently, the enzymes float in an aqueous solution, and as carbon dioxide is added, white cellulose will appear inside the reactor within a few minutes, Mashouf said. The reactors fit inside shipping container-sized modules. Eventually, Rubi plans to change its process to allow for continuous production.

While the startup is targeting apparel companies as its first customers, eventually it hopes to provide cellulose to any industry that uses it. “This really is a platform,” Mashouf said. “We think of it as a platform to make all the important chemicals and materials across the economy in a low-cost way.”

Gecko Robotics lands the largest U.S. Navy robotics deal yet

The U.S. Navy has inked its largest robotics deal yet as the military branch looks to use robots to keep up with its fleet maintenance.

Gecko Robotics, a Pittsburgh-based company that makes robots and sensors for inspecting large industrial assets, has signed a five-year IDIQ (indefinite delivery, indefinite quantity) deal with the U.S. Navy and U.S. General Services Administration (GSA), the company announced on Tuesday. The deal starts with an initial $54 million award and has a $71 million ceiling.

The Navy will use Gecko’s robots and sensors to monitor the status and health of the U.S. Navy’s assets and fleets of ships, starting with 18 ships in the U.S. Pacific Fleet.

Gecko founder and CEO Jake Loosararian told TechCrunch that the company’s robots will crawl into every nook and cranny of the ships to create a detailed digital replica — sometimes called a “digital twin” — of each vessel. The company’s software will help the organization monitor the assets and recommend maintenance, trying to get ahead of problems before they arise and reduce maintenance times and cost.

“Once you create that digital representation using the robotic systems of the health and the condition of these assets, and even the digitization of the environment itself, then you can accelerate how quickly you can make decisions and repair,” Loosararian said. “You want to be able to build this living, breathing model that ensures that you’re reducing days into the future that these assets have to spend [out of service].”

This deal is meant to help the Navy reach its goal of having 80% ship readiness by 2027. Today, about 40% of the Navy’s fleet is unavailable at any given time due to the long maintenance cycles on these vessels.

“It’s like $13 billion to $20 billion a year in maintenance,” Loosararian said. “At a time when you need every asset you can get, that’s pretty critical. And these assets aren’t getting any younger either.”

Gecko has been working with the U.S. Navy for four years. After a port engineer stationed in Japan reached out to learn more about the company, Gecko conducted an evaluation and a drew up a preventative maintenance plan. The Navy was impressed, and the relationship grew from there, leading up to Tuesday’s deal.

“We’re helping to ensure that our critical assets live as long as they can and never are down,” Loosararian said. “I want to live in a world where we don’t have ships going through maintenance cycles, because we just know what’s broken and what to fix while they’re actually deployed. That’s my vision of the future, whether it’s a military asset or it’s a power plant.”

Amazon adds 1-hour and 3-hour delivery options in the US

Amazon is launching one-hour and three-hour delivery options across many cities in the U.S. as the e-commerce giant looks to compete with instant delivery companies like Instacart, DoorDash, and Uber Eats.

The e-commerce giant is making more than 90,000 items available via this new delivery system. If an item can be delivered to a user within one or three hours, they’ll see a label saying so next to that item on the Amazon app. There’s also a filter for these new delivery options in the app and on the site.

Amazon Prime subscribers will be charged $9.99 for one-hour deliveries and $4.99 for three-hour deliveries. If you don’t have a Prime subscription, you’ll pay $19.99 for one-hour deliveries and $14.99 for three-hour deliveries.

Amazon said it is making the one-hour delivery option available in hundreds of cities in the U.S., including parts of major metropolitan areas like Los Angeles, Chicago, and Washington, D.C., as well as Des Moines, Boise, and American Fork. The three-hour option is available in over 2,000 U.S. cities and towns.

The company is also launching a dedicated storefront to house items eligible for these new delivery options.

“Our customers are busier than ever and are looking for new ways to save time while keeping their households running. We saw an opportunity to use our unique operational expertise and delivery network to help make customers’ lives a little easier while unlocking even more value for Prime members,” Udit Madan, senior vice president of Worldwide Operations at Amazon, said in a statement.

The company said it is using its existing, same-day fulfillment sites for the new delivery options.

This isn’t the first time Amazon has tried its hand at instant deliveries. The company previously launched one-hour deliveries under the “Prime Now” service in 2014, but it was discontinued in 2021. And then in December 2025, it piloted a 30-minute delivery option in Seattle and Philadelphia.

The company has been trying to get into the quick-commerce game worldwide. In India, the company in 2024 launched Amazon Now, a 10-minute delivery service for groceries and other items, and last year expanded it to several cities. Amazon launched the service in the United Arab Emirates last October, promising deliveries within 15 minutes.

Gamma adds AI image generation tools in bid to take on Canva and Adobe

Gamma, a platform that lets you use AI to create presentations and websites, is launching a new image-generation product for making marketing assets as it seeks to better compete with the likes of Canva and Adobe.

The company says its new product, called Gamma Imagine, will let users employ text prompts to create brand-specific assets like interactive charts and visualizations, marketing collateral, social graphics, and infographics. Gamma currently provides more than 100 templates, which you can use alongside its AI tools to build the kind of assets that you need.

To power its data-driven asset generation features, the company is integrating with tools like ChatGPT, Claude, Make, Zapier, Atlassian, n8n, and Superhuman Go.

“As we started working with a lot of our early users, we realized that in the presentations they want to create, there was a variety of graphical design use cases that they all also had,” Grant Lee, Gamma’s CEO and co-founder, told TechCrunch. “So we worked alongside them to develop basically a new set of tools that allows them to go far beyond just the traditional presentation format,” he said.

Lee believes Gamma sits well between tools for professionals like Adobe or Figma, and legacy tools like Microsoft PowerPoint.

“We think we can serve the very long tail of knowledge workers and business professionals whose demand for their job is to communicate visually, but they just don’t have the tools. They need to pull in a design resource to be able to help with this stuff, and we want to make an-AI native approach that serves their needs in the sort of middle that we feel is really underserved,” he said.

Last November, Gamma raised $68 million in a Series B round led by a16z, at a $2.1 billion valuation. At that time, the company said it had ARR of $100 million, and 70 million users. The company told TechCrunch that it is approaching 100 million users now.
