Houstonian Steffie 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.

“I thought, ‘why can’t we start with a sneaker material and then build a heel around it?’” she tells InnovationMap. “I started just slicing everyone else’s shoes and now I’m more convinced than ever that our shoe is different.”

Tomson was inspired to design the inaugural shoe for Getaway Sticks after her own struggle with heels, walking in the bustling Texas Medical Center from building to building for meetings. As a mom of two and a problem solver, she knew there had to be a better mousetrap. Click here to read more.

With an unstable energy grid, two Houstonians know at least one solution in the evolving energy industry: Microgrids.

Ed Pettitt and Paresh Patel co-founded InnoGrid, a social enterprise working to establish community microgrids in lower income areas — neighborhoods that are most at risk of devastating power outages.

"We want to convert the commercial microgrid model for low and moderate income and undresourced residential communities," Patel explains on the latest episode of the Houston Innovators Podcast. Click here to read more and stream the episode.

Houston founders aim to provide equity through energy resiliency

Houston innovators podcast episode 143

As temperatures climb and devastating natural disasters continue to test the power grid, two Houston innovators have a solution: Smart microgrids.

"Microgrids have been around for a very long time," Paresh Patel, co-founder of InnoGrid, says on the Houston Innovators Podcast. "We're primed here in Houston and in Texas to really see microgrids go mainstream. ... People want to see that they have control and are in charge of their own power."

Patel co-founded InnoGrid with Ed Pettitt and a few other collaborators following the 2020 Houston Climathon. The social enterprise is working to establish community microgrids in lower income areas — neighborhoods that are most at risk of devastating power outages.

"We want to convert the commercial microgrid model for low and moderate income and undresourced residential communities," Patel explains.

And there's never been a better time to shine a spotlight on microgrids as a solution to unreliable power systems, Pettitt says.

"We're dealing with massive inflation — costs are going up especially in food and energy," he explains on the show. "Even prior to this time of inflation, electricity prices in the US were expected to increase across the board. Hundreds of thousands of people right now today are being pushed below the poverty line because of increased energy costs. We need to be more creative in how we upgrade our infrastructure."

And the current grid system is well overdue for an upgrade. The microgrid system fits right in with the shared economy we live in today, Patel says, and it allows for more generation of energy that is decentralized, digitalized, decarbonized, and democratized — the four Ds as he says.

"When you consider our current grid system, it is a vestige of the industrial revolution — it's 140 years old. That business model is ripe for innovation," Patel says.

"We need to accelerate deployment of microgrid models," he continues. "I don't think we can afford to update our current grid system — it'll cost $2 trillion."

Most importantly, these microgrids need to be implemented in an equitable way, the founders say, and InnoGrid has its eyes on one Houston area in particular. The Innovation Corridor, which spans from the Texas Medical Center to Downtown Houston, would be the ideal region to deploy the technology.

"If you look at the innovation corridor, it forms the spine of the city. You have so many important municipal buildings, first-responding organizations, and a large amount of affordable housing in the area. There's critical resources here that we want to make sure the lights stay on in power disasters," Pettit says. "One of the things we believe at InnoGrid is that where you live shouldn't determine whether or not you survive a national weather event. We want to make sure we provide energy stability in the communities that need it most."

To make this dream into a reality, InnoGrid needs the right partnerships and support in the area — and the founders have made progress. InnoGrid recently participated in the Ion Smart and Resilient Cities Accelerator and has a relationship with Greentown Houston across the street.

Eventually, as Pettit says, InnoGrid wants to help lead Houston to becoming a hub for microgrid innovation.

"We're looking at other cities — like Chicago and Boston — and how they've deployed their microgrids and making sure we're bringing those best practices in Houston," Pettit says. "Eventually we want to be the leader in developing these microgrid best practices as the energy capital of the world."

Houston Climathon winning microgrid solution is more important now than ever

thinking small

More than 6,000 participants in 145 cities around the world gathered virtually for last year's Climathon, a global event put on by Impact Hub Houston to unite innovators and collaborate on climate solutions. When Winter Storm Uri left the Texas energy grid in a state of crisis, one Climathon Houston team's proposal for energy reliability became all the more important.

Last year, the City of Houston unveiled its first Climate Action Plan to address the city's challenges and strive to lead the energy transition. It was the perfect roadmap for Climathon Houston, a hackathon where eleven teams gathered to develop and pitch a concept to align with the city's new plan.

Of the three winning teams, one idea was prescient in its approach to energy. Six energy-focused Texans drew up plans for InnoGrid, a cost-effective strategy to build the first microgrid in Houston. What started as a pitch has become a developed proposal gaining collaborator and city interest in the wake of Uri.

Bryan Gottfried, Edward D. Pettitt II, Andi Littlejohn, Paresh Patel, Ben Jawdat, and Gavin Dillingham created InnoGrid to to help achieve the CAP's energy transition and net-zero emissions goals. With climate events increasing rapidly, the team of innovators saw an opportunity to create a sustainable solution — the first Houston microgrid.

In just an hour and a half of brainstorming, the team sought to create a similar model to Austin's Whisper Valley microgrid — a project that's currently in development. While Whisper Valley is a master plan community, the team wanted to create a microgrid to support a larger picture: the city of Houston.

"I had been following transactive energy models [such as] peer-to-peer electricity trading like Brooklyn Microgrid/LO3 Energy and Power Ledger since their inception. This inspired my vision for a novel microgrid that would demonstrate such technologies in the energy capital of the world that is otherwise primarily focused on oil and gas, and natural resources," explains Patel, founder and CEO of e^2: Equitable Energy.

When Pettitt joined the group, he proposed the growing Houston Innovation Corridor as the home to InnoGrid. The four-mile stretch between the Texas Medical Center and Downtown is already home to green technology, making it an ideal fit.

"You're going into an area that was already being redeveloped and had this innovation kind of mentality already," explains Gottfried, a geoscientist and current MBA student at University of Houston Bauer College of Business.

After winning Climathon Houston, the team continued to meet weekly in hopes of making InnoGrid a reality.

The case for a microgrid

The InnoGrid team started with the goal of making energy reliable and resilient in the face of climate change. While previous storms like Hurricane Ike have left millions of Texans without power, Winter Storm Uri was one of the most destructive tragedies to face Texas. The unexpected February storm left 4.5 million Texans without electricity and resulted in at least 111 deaths.

As InnoGrid's team members struggled with burst pipes and loss of power, the team juggled the task of submitting a grant application to the Department of Energy during a catastrophic winter storm. The timing was not lost on them.

"It underscored the need for us to do something like this," shares Gottfried.

To understand how impactful a Houston microgrid can be, you first must understand how a microgrid works. A microgrid is a local energy grid made of a network of generators combined with energy storage. The microgrid has control capability, meaning it can disconnect from a macro grid and run autonomously.

Ultimately, microgrids can provide reliability and drive down carbon emissions. Using smart meters, the grids can even provide real-time energy data to show the inflow and outflow of electricity. In the instance a microgrid does go down, it only affects the community — not the entire state. Likewise, during a power outage to the main grid, a microgrid can break away and run on its own.

Microgrids have been deployed by other cities to mitigate the physical and economic risks caused by power outages, but the use of a project like InnoGrid feels especially timely given recent events and the limitations of the Texas Interconnect.

The Texas grid is isolated by choice, separated from the eastern and western interconnects. Texas' isolated energy grid resulted in a massive failure, proving deregulation can certainly backfire. Updating the electric grid has an expensive price tag, but microgrids show a promising and cost-effective model for the future.

"I thought if microgrids and mini-grids are enabling millions in off-grid frontier markets at the base of the pyramid [like Asia, Sub-Saharan Africa, etc.] to essentially leapfrog legacy energy infrastructure, why should we not upgrade our aging power system with the latest tech that is digitalized, decarbonized, decentralized/distributed, and democratized at the top of the pyramid," asks Patel.

Many hospitals, universities, and large technology firms have already established their own microgrids to protect equipment and provide safety. Still, smaller businesses and homes in the community can suffer during outages.

InnoGrid's proposal seeks to use existing and proven renewable energy sources like wind, solar and geothermal energy. The storage technologies used would include battery, kinetic, compressed air, and geomechanical pumped storage.

"From the perspective of an early-stage hardware startup, one of the most important things is finding a way to validate and test your technology," explains Jawdat, founder and CEO of Revterra and adviser to the InnoGrid team. He explains that the microgrid "can also be a testbed for new technologies, specifically, new energy storage technologies," through potential partnerships with companies like Greentown Labs, which is opening its Houston location soon.

Battling inequity 

While the outlook for a community microgrid is enticing, there are also challenges to address. One key challenge is inequity, which is a key focus of Pettitt who was drawn to the team's goal of providing stability for companies and residences in Houston.

Pettitt, who is seeking a Ph.D. in urban planning and environmental policy at Texas Southern University, has a background in public health and frequently works with the Houston Coalition for Equitable Development without Displacement. "I'm really looking at the intersection of the built environment and how to make cities healthier for its residents," he shares.

"A lot of companies are trying to prevent this climate crisis where we have climate refugees that can't live in certain areas because of ecological damage. But in the process, we don't want to create economic refugees from the gentrification of bringing all of these companies and higher-wage jobs into an area without providing folks the ability to benefit from those jobs and the positive externalities of that development," explains Pettitt.

The InnoGrid would plan to provide positive externalities in the form of energy subsidies and potentially even job training for people who want to work on the grid.

Power to the consumer

Much like the gamification in feel-good fitness trackers and e-learning tools, reward systems can inspire friendly competition and community engagement. InnoGrid's proposal seeks to challenge other major cities to build their own grids and compete with a gamified system.

The Innovation Corridor is currently undergoing major redevelopment, the first 16 acres of which are being developed by Rice Management Company and will be anchored by The Ion, which is opening soon. The timing of this redevelopment would allow a prospective project like InnoGrid to build in visual and interactive aspects that depict energy usage and carbon offsetting.

The microgrid's statistics would also engage Houstonians by sharing up-to-date data through dashboards, apps, and even billboards to track Houston's carbon footprint. Pettitt paints a picture of interactive sidewalk structures, leaderboards, and digital billboards in the public realm to showcase how energy is used day-to-day. The team hopes to build positive feedback cycles that encourage tenants and building owners to be more energy-efficient.

"If we're having an Innovation Corridor, an innovation district, I think the built environment should be innovative too," explains Pettitt.

The future of InnoGrid

Every innovation has to start somewhere. While InnoGrid is in its early stages, the team is working to establish partners and collaborators to make the project a reality.

Inspired by projects like the Brooklyn Microgrid, InnoGrid is in the process of pursuing partnerships with utilities and energy retailers to form a dynamic energy marketplace that pools local distributed energy resources. The team hopes to collaborate with microgrid experts from around the nation like Schneider Electric and SunPower. Other potential collaborators include The Ion, CenterPoint, Greentown Labs, and Rice Management Company.

Can Houston remain the energy capital of the world as it transitions to a net-zero energy future? The InnoGrid team wants to make that happen. The argument for a microgrid in Houston feels even more fitting when you look at the landscape.

"If we are going to create an innovative microgrid that also functions as a testbed for innovators and startups, [we] have proximity to some of the biggest utilities and power generation players right in that sector," explains Patel, who is also an inaugural member of Greentown Labs Houston.

"The microgrid itself is not novel. I think what makes it compelling is to situate that right here in the heart of the energy capital as we, again, reincarnate as the energy transition capital world," Patel continues.

Houston lab-test startup seeks $1M for nationwide expansion

Testing Access

Health care industry veteran Jim Gebhart knew there had to be a better way for patients to access lab services, especially those with high health insurance deductibles or no insurance at all.

“This challenge became deeply personal when a close family member developed a serious illness, and we struggled to secure prompt appointments,” Gebhart tells InnovationMap. “It’s incredibly frustrating when a loved one cannot receive timely care simply because of provider shortages or the limited capacity of traditional clinics.”

Driven by the desire to knock down lab-test barriers, Gebhart founded Houston-based TheLabCafe.com in 2024. The platform provides access to low-cost medical tests without requiring patients to carry health insurance. TheLabCafe serves patients in six states: Texas, Georgia, Louisiana, Nevada, New Mexico and Oklahoma. Gebhart, the startup’s CEO, says that by the end of March, LabCafe will be offering services in 20 more states and the District of Columbia.

Gebhart has spent more than 30 years in the lab industry. His career includes stints at Austin-based Clinical Pathology Laboratories, Ohio’s Cleveland Clinic Laboratories and Secaucus, New Jersey-based Quest Diagnostics.

“Since nearly 80 percent of disease diagnoses rely on laboratory testing, I decided to leverage my background to create a more accessible, self-directed process for individuals to order blood and urine tests on their own terms — when and where they need them,” says Gebhart.

So far, Gebhart is self-funding the startup. But he plans to seek $700,000 to $1 million in outside investments in late 2026 to support the nationwide expansion and the introduction of more services.

TheLabCafe contracts with labs for an array of tests, such as cholesterol, hepatitis, metabolic, testosterone, thyroid and sexually transmitted infection (STI) tests. A cholesterol test obtained through TheLabCafe might cost $29, compared with a typical cost of perhaps $39 to $59 without insurance.

A health care professional reviews every test, both when the test is ordered and when the results are delivered, often within 24 hours. After receiving test results, a patient can schedule a virtual visit with a health care professional to go over the findings and learn potential treatment options.

Gebhart says TheLabCafe particularly benefits uninsured patients, including those in Texas. Among the states, Texas has the highest rate of uninsured residents. U.S. Census Bureau data shows 21.6 percent of adults and 13.6 percent of children in Texas lacked health insurance in 2024.

“Uninsured patients often pay the highest prices in the health care system,” Gebhart explains. “We address this by offering straightforward pricing and convenient access to testing without requiring insurance.”

“Our rates are intentionally set to remain affordable, helping individuals take a proactive approach to their health,” he adds. “Regular testing enables people to identify potential health issues early and track their progress as they make lifestyle changes. Ultimately, you can’t measure improvement without data — and laboratory results provide that data.”

Houston geothermal startup secures $97M Series B for next-gen power

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.
