Before starting her business, Houstonian Steffie Tomson ordered $2,000 worth of shoes and sliced them all in half with a bandsaw just to see what was inside. Tomson, a neuroscientist by trade and the founder and CEO of footwear startup Getaway Sticks, had an idea for a different kind of shoe — one that was redesigned to prioritize women’s comfort.

Earlier this year, Tomson shared the Getaway Sticks origin story with InnovationMap. The heels are available online for around $200 per pair.

For the resident chef: Fresh fish delivered

Houstonians Melissa Harrington and Emily Castro saw how beneficial incorporating fish into your diet can be — so they decided to launch an easier way to do it. They launched Fish Fixe in 2017 to deliver seafood with easy-to-access instructions on storage and thawing — plus cooking recipes that take around 20 minutes.

The duo appeared on the 13th season of Shark Tank last year. In 2020, as InnovationMap reported, the company saw a 400-percent increase in sales. They pitched asking for $200,000 in investment. Lori Greiner, the "queen of QVC," took the bait — and 25 percent equity.

Shoppers can stock up on various boxes from $109 to $219, or opt for a gift card for their loved one.

For the health nut: Sustainably-sourced nutrients

Houston--based iwi creates nutritional supplements for the brain and the heart — and they are doing it in a sustainable setting: algae farms. These football field-sized farms operate on desert land using just salt water and sand and produce algae sustainably — all while absorbing CO2. Miguel Calatayud, CEO of the company, tells InnovationMap that the farms even area able to reuse 98 percent of the water involved in the process. Earlier this year, iwi received an investment from a local group in an $8 million deal.

The company has almost a dozen options online for around $30 per canister of supplements.

For your aging loved ones: Afterlife planning and memory keeping

There's a lot that goes into legacy and afterlife planning, and a Houston startup has emerged to make the process a whole lot easier. The Postage helps its users generate their wills and organize information to leave behind, the company's founder, Emily Cisek, shares with InnovationMap. The platform also every user to leave messages, photos, and memories in a digital vault that will stand the test of time.

Giving the gift of legacy planning can be an option for anyone in your family — from the grandparents to the newlyweds.

For someone seeking luscious locks: Hair growth tracking kit

While it might seem odd to gift someone a hair loss tracking kit, this product from a Houston company has helped many men and women suffering from hair density challenges. MyHairCounts created a hair density imaging kit and app based on proprietary and patent-pending software. The kit includes a variety of items such as scalp imaging guides, a comb, and gel to help individuals photograph their hair follicles at specified angles. Users then upload these photographs into the app for analyses which are delivered within 48 hours. These analyses inform the user whether or not their hair regrowth treatment is effective.

The kit itself is just $40 and available online. Users can work with the company on a longer hair growth plan, too.

Bonus: What to bring to the table

After catching a deal on Shark Tank, these Houston-area fish foodies swim toward more funding

reeling in cash

The benefits of working more fish into your diet are as endless as the vast ocean itself, but going about buying and cooking fish is an expensive and daunting process.

Houstonians Melissa Harrington and Emily Castro thought they could help and launched Fish Fixe in 2017 to tackle these challenges and bring high quality seafood direct to consumers. Fish Fixe delivers seafood with easy-to-access instructions on storage and thawing — plus cooking recipes that take around 20 minutes.

The duo launched the company in 2017 and appeared on the 13th season of Shark Tank last year. In 2020, with more people avoiding grocery stores and restaurants, they saw a 400-percent increase in sales. They pitched asking for $200,000 in investment. Lori Greiner, the "queen of QVC," took the bait — and 25 percent equity.

“COVID-19, which forced more people to eat at home and adopt direct-to-consumer services, and Shark Tank were both spring boards for our sales, and through these events we've been able to retain many customers,” says Harrington.

In order to sustain this growth and provide more opportunities to scale, Harrington and Castro put the Shark Tank investment into their distribution line and moved everything into a centralized distribution center which replenishes distribution centers in other parts of the country.

“By late Q2, we will have four distribution centers that can hit 99 percent of the US in less than two days,” says Harrington.

Up next, Harrington and Castro have their sights set on the customer experience and the content space, which they hope to support with some outside funding.

“We are going to go raise some money because we truly feel that with the right resources we can scale and serve more people and spread the message,” says Harrington. “The hard work, we kind of feel like, has already been done in the setup and now it’s time to go have fun and go market, which is really fun.”

Prior to Fish Fixe, Harrington and Castro both worked in food and beverage. Harrington worked in the live lobster business and sold lobsters to high-end Houston restaurants and HEB. Castro worked in wine and spirits and managed a team of 50 sales professionals. Leveraging that depth of experience, they were able to bring Fish Fixe from concept to market in 90 days.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”

12 Houston climatetech startups join Greentown Labs' growing incubator

Startup Talk

More than 40 climatetech startups joined the Greentown Labs Houston community in the second half of 2025, 12 of which hail from the Bayou City.

The companies are among a group of nearly 70 total that joined the climatetech incubator, which is co-located in Houston and Boston, in Q3 and Q4.

The new companies that have joined the Houston incubator specialize in a variety of clean energy applications, from green hydrogen-producing water-splitting cycles to drones that service wind turbines.

The local startups that joined Greentown Houston include:

  • Houston-based Wise Energie, which delivers turnkey microgrids that blend vertical-axis wind, solar PV, and battery storage into a single, silent system.
  • The Woodlands-based Resollant, which is developing compact, zero-emissions hydrogen and carbon reactors to provide low-cost, scalable clean hydrogen and high-purity carbon for the energy and manufacturing sectors.

  • Houston-based Torres Orbital Mining (TOM),which develops autonomous excavation systems for extreme environments on Earth and the moon, enabling safe, data-driven resource recovery and laying the groundwork for sustainable off-world industry.

Other startups from around the world joined the Houston incubator in the same time period, including:

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

Intuitive Machines forms partnership with Italian companies for lunar exploration services

to the moon

Houston-based space technology, infrastructure and services company Intuitive Machines has forged a partnership with two Italian companies to offer infrastructure, communication and navigation services for exploration of the moon.

Intuitive Machines’ agreement with the two companies, Leonardo and Telespazio, paves the way for collaboration on satellite services for NASA, a customer of Intuitive Machines, and the European Space Agency, a customer of Leonardo and Telespazio. Leonardo, an aerospace, defense and security company, is the majority owner of Telespazio, a provider of satellite technology and services.

“Resilient, secure, and scalable space infrastructure and space data networks are vital to customers who want to push farther on the lunar surface and beyond to Mars,” Steve Altemus, co-founder and CEO of Intuitive Machine, said in a news release.

Massimo Claudio Comparini, managing director of Leonardo’s space division, added that the partnership with Intuitive Machines is a big step toward enabling human and robotic missions from the U.S., Europe and other places “to access a robust communications network and high-precision navigation services while operating in the lunar environment.”

Intuitive Machines recently expanded its Houston Spaceport facilities to ramp up in-house production of satellites. The company’s first satellite will launch with its upcoming IM‑3 lunar mission.

Intuitive Machines says it ultimately wants to establish a “center of space excellence” at Houston Spaceport to support missions to the moon, Mars and the region between Earth and the moon.
