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.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."
