One of the dozen or so Houston startups kicking of the new year with fresh funding is SmartAC.com, a company that's designed a platform that enables contractors in the HVAC and plumbing industries to monitor, manage, and optimize their maintenance memberships through advanced sensors, AI-driven diagnostics, and proactive alerts.

Last month, the SmartAC.com raised a follow-on round with support from local investor Mercury to continue growth and expansion of the product, which has evolved on many ways since the company launched in 2020, emerging from stealth with $10 million raised in a series A. In a May 2023 interview for the Houston Innovators Podcast, Founder and CEO Josh Teekell explained how he embraced the power of a pivot.

The company's sensors can monitor all aspects of air conditioning units and report back any issues, meaning homeowners have quicker and less costly repairs. While SmartAC.com started with providing the service and tech to homeowners directly, Teekell says he's had a greater interest in working with plumbers and HVAC companies who then deploy the technology to their customers.

"It became quite evident that homeowners don't care about air conditioning really at all until their system breaks," Teekell says on the show. "The technology is really built around giving those contractors as another way to gain a customer relationship and keep it."

Revisit the podcast episode below where Teekell talks about SmartAC.com's last raise.

SmartAC.com's previous round in 2023 — a $22 million series B — was used grow its team that goes out to deploy the technology and train the contractors on the platform.

"We've been very fortunate to get some of the biggest names in Houston on our cap table," Teekell says in the May 2023 conversation. "Since we're raising a bunch of money locally, everyone understands what a pain air conditioning can be."

Houston superconductor tech manufacturer raises $25M

fresh funding

A Houston company has closed its series B extension at $25 million.

MetOx International, which develops and manufactures high-temperature superconducting (HTS) wire, announced it closed a $25 million series B extension. Centaurus Capital, an energy-focused family office, and New System Ventures, a climate and energy transition-focused venture firm, led the round with participation from other investors.

"MetOx has developed a robust and highly scalable operation, and we are thrilled to partner with the Company as it enters this pivotal growth stage," says John Arnold, founder of Centaurus, in a news release. "The market for HTS is expanding at an unprecedented pace, with demand for HTS far outweighing supply. MetOx is poised to be the leading U.S. HTS producer, closing the supply gap and bringing dramatic capacity to high power innovations and applications. Their progress and potential are unmatched in the field, and we are proud to support their growth."

The fresh funding will go toward advancing the company's Xeus HTS wire technology for key energy transition applications by expanding MetOx's U.S.-based manufacturing capabilities to meet demand.

"This funding marks a pivotal step in our mission to revolutionize the energy and technology sectors with our advanced power delivery technology and accelerate delivery for our customers and partners. HTS is critical to enhancing the efficiency of our electric grid and enabling technological developments that, in many cases, would not be viable or even possible without superconductor technology," adds Bud Vos, CEO of MetOx. "Support from investors such as Centaurus and NSV not only provides the financial resources and strategic support required for accelerated scaleup, but also validates the broad reach of our technology across energy, data center, medical, and defense industries."

HTS wire technology is critical for the energy transition, especially amid rising data center growth, and for next generation wind turbines and interconnections.

MetOx's technology originated out of the University of Houston and was founded in 1998 by Alex Ignatiev, UH professor emeritus of physics and a fellow of the National Academy of Inventors. Last year, the company secured $3 million in funding from the U.S. Department of Energy to support the advancement of its proprietary manufacturing technology for its HTS wire.

"MetOx's HTS technology aligns with our systems-level research and offers a unique opportunity to dramatically accelerate the energy transition," says Ian Samuels, founder and managing partner at NSV. "MetOx's Xeus wire stands to be a force multiplier in clean energy generation and high-power transmission and distribution, enabling load growth and the deployment of power-dense data centers. NSV is excited to support MetOx as it scales domestic manufacturing capacity."

Power grid tech co. with Houston HQ raises $25M series B

money moves

A Norway-based provider of technology for power grids whose U.S. headquarters is in Houston has raised a $25 million series B round of funding.

The venture capital arm of Polish energy giant Orlen, Norwegian cleantech fund NRP Zero, and the Norway-based Steinsvik Family Office co-led Heimdall Energy's round. Existing investors, including Investinor, Ebony, Hafslund, Lyse, and Sarsia Seed, chipped in $8.5 million of the $25 million round.

“This funding gives us fuel to grow internationally, as we continue to build our organization with the best people and industry experts in the world,” Jørgen Festervoll, CEO of Heimdall, says in a news release.

Founded in 2016, Heimdall supplies software and sensors for monitoring overhead power lines. The company says its technology can generate up to 40 percent in additional transmission capacity from existing power lines.

Heimdall entered the U.S. market in 2023 with the opening of its Houston office after operating for several years in the European market.

“Heimdall Power has built itself a unique position as an enabler for the ongoing energy transition, with fast-increasing electricity demand and queues of renewables waiting to get connected,” says Marek Garniewski, president of Orlen’s VC fund.

Heimdall says it will put the fresh funding toward scaling up production and installation of its “magic ball” sphere-shaped sensors. In the U.S., these sensors help operators of power grids maximize the capacity of the aging power infrastructure.

“In the United States alone, there are over 500,000 miles of power lines — most of which have a far higher transmission capacity than grid operators have historically been able to realize. To increase capacity, many have launched large-scale and expensive infrastructure projects,” Heimdall says.

Now, the U.S. government has stepped in to ensure that utilities are gaining more capacity from the existing infrastructure, aiming to upgrade 100,000 miles of transmission lines over the next five years.

Heimdall's technology enables grid operators and utilities to boost transmission capacity without undertaking lengthy, costly infrastructure projects. Earlier this year, the company kicked off the largest grid optimization project in the U.S. with Minnesota-based Great River Energy.

Houston cardiac health startup raises $43 million series B to grow AI-backed platform

money moves

A Houston-based tech company that has a product line of software solutions for cardiac health has raised funding.

Octagos Health, the parent company of Atlas AI — a software platform for cardiac devices like pacemakers, defibrillators, ambulatory monitors and consumer wearables — has announced a $43 million series B raise that will bring their technology to many more hearts.

Morgan Stanley Investment Capital led the investment, which also included funds from Mucker Capital and other continuing strategic investors. The goal of the raise is to supply funds to accelerate Atlas AI’s growth across the United States and to expand into other areas of care, including ambulatory monitors, consumer wearables, and sleep.

"This investment will enable us to accelerate enhancements to our platform, in addition to scaling our commercial team and operations. We are currently the only company that helps cardiology practices migrate their historical data from legacy software providers and fully integrates with any EHR (exertion heart rate) system. We do this while enabling customized reporting supported by patient and practice decision-support analytics," says Eric Olsen, COO of Octagos Health, in a press release.

Octagos Health was founded by a team of healthcare pros including CEO Shanti Bansal, a cardiologist and founder of Houston Heart Rhythm, an atrial fibrillation center. The goal was to find a new way to deal with the massive amount of data that clinicians encounter each day in a way that combines software and the work of human doctors.

According to the Octagos Health website, “Our solution allows clinicians to focus on other ways of delivering meaningful healthcare and more efficiently manage their remotely monitored patients.”

It works thanks to customizable reporting features that allow patients’ healthcare teams to get help while monitoring them, but to do it precisely as they would if they were crunching numbers themselves.

"We are excited to partner with Octagos Health and support their vision of transforming cardiac care," says Melissa Daniels, managing director of Morgan Stanley Expansion Capital. "Octagos Health has demonstrated exceptional growth and innovation in a critical area of healthcare. We believe their platform and vertically integrated software and services significantly improve patient care and streamline cardiac monitoring processes for healthcare providers."

Will Hsu, co-founder and partner of Mucker Capital, agrees. “Octagos Health is poised for scale – industry leading gross margins, a very sticky product that doctors and clinical staff love, and a market ready for disruption with artificial intelligence. This is the new wave for diagnostic care,” he says. And with this raise, it will be available to even more clinicians and patients across the country.

Founded in 2016, Welligence specializes in data and intelligence for the oil and gas markets, greenhouse gas emissions sector, and carbon capture, storage, and utilization (CCUS) projects. Clients include major oil and gas companies, as well as large investment banks.

“Our team is proud of the growth we’ve achieved over the last six years. The foundation of Welligence has now been built. We have a world-class team, a robust database and platform, and a brand recognized globally in our industry,” Welligence co-founder and CEO Ross Lubetkin says in a news release. “Raising significant capital from some of the market’s most sophisticated investors with a proven track record is a pivotal step towards realizing the Welligence vision — to solidify our presence as a leading global energy research house.”

Welligence says it will use the funding to beef up its product offerings, expand its geographic data capabilities, and enter new energy research verticals. The company has employees and clients in North America, Africa, Asia, Europe, Latin America, and the Middle East, and it plans to open more global offices.

“We have been extremely impressed by the Welligence team and product and are excited by the scalability of the platform. Through the company’s use of new technology, ideas, and methodologies, Welligence continues to take market share in a space traditionally monopolized by a few legacy players,” says Christopher De Souza, a partner at Elephant. “Welligence’s global energy database positions it well for expansion into new frontiers.”

Houston HR tech platform plans to grow team, expand internationally with recent $21M raise

big kahuna

With a recent $21 million series B funding round set to fuel more growth and expand an impressive client roster, Kahuna Workforce Solutions is riding a big wave into 2024.

CEO Jai Shah tells InnovationMap that the Houston skills management software service company’s Hawaiian name captures their style.

“Kahuna is that kind of expert, competent leader in a tribe or family,” Jai says. “That’s all because we had this concept of really wanting to be providing a very..family-oriented consulting approach. Treat our customers like family, and with respect, love and really just try and deliver on that promise.”

For Shah, Kahuna represents a natural progression, and grew out of his first startup, Hula Partners, a Houston consulting company acquired by GP Strategies Corp. in 2017.

Shah says his initial work in human resource technology transformation for energy giants like Marathon Oil exposed the poor functionality of HR software, especially for employees. The very technology that has revolutionized the workplace has often not met the needs of many American workers, even as they face more demands on their time.

“We saw a need in the marketplace, relative to the consulting, where technology really wasn’t filling the gap,” says Shah, who now lives in San Diego.

Kahuna’s skills management software service bridges that gap, enabling employees train and grow within their field, and employers to track and monitor their progress in key competencies.

Whether it’s a nurse assessing a patient, or a worker turning a wrench properly on an oil rig, employers observe those skills and record them in Kahuna’s software.

“What Kahuna does, is give the organization a lot more confidence in their ability to have these workers do their jobs,” Shah says.

Those frontline workers drive the company’s ethos. “That workforce is super key to the economy, and it’s really been undeserved by technology for many years. That’s why we exist,” says Shah.

Kahuna caught the attention of Baltimore, Maryland-based Resolve Growth Partners, which chose Kahuna as the first investment in their second funding group with the series B. Kahuna’s series A funding came from venture capital group Houston Ventures.

Chip Davis, of Houston Ventures, who remains a key figure in Kahuna, says he experienced his “Eureka moment” when he saw how Kahuna could solve a problem that he witnessed firsthand in another company. He had another investment client in the oil industry, that had tons of data, but didn’t know what to do with it. He saw that Kahuna provides a way.

“The type of data that Kahuna developed, is not easy to develop,” Davis says. “It knows not that just that you went to college; it knows how well you did, and it knows how well you’re doing now, and it knows why you’re doing well now."

Shah says Kahuna’s ability to leverage that granular data sets the company apart from other HR applications. And that technology may even extend to the future workforce.

Memorial Hermann, a new customer, is in discussions with Kahuna to implement its software early in the journey for nursing candidates, in secondary education curriculum.

Students as young as seventh grade who aspire to a nursing career, could use Kahuna software to find out what skills they’ll need, and keep

Shah says the funds from Resolve, divided in two tranches, will help grow his staff of 50 employees by 30 percent. He also says he plans three or four major initiatives in product development, such as artificial intelligence and machine learning and developing new software modules.

The company will remain headquartered at its Houston office on upper Kirby, but plans are underway to expand operations in about a year into Northern Europe, where many energy clients do business.

Kahuna will maintain growth with a laser focus on frontline workers, Shah says, and solidify its position as a category leader in the energy, manufacturing, and health care verticals.

“A lot of these companies are being challenged in more technically tough environments,” he says. “We’re drilling for oil in deeper and deeper ocean centers. Nurses are asked to do more these days than they were five years ago, or 10 years ago.”

Kahuna’s move upmarket may bring challenges common to companies making that same progression, with a more sophisticated buying process and the scrutiny that comes with it.

“An upmarket customer wants to know how you can support them. They’re going to examine you, in a way you’re not used to being examined,” Davis says.

Houston-founded startup raises $1.2M and moves headquarters to Detroit

moving forward

Houston-founded ChurchSpace, known as the Airbnb for churches, has formed an official partnership with the City of Detroit and will relocate its headquarters.

The announcements come as the company successfully closed a $1.2 million oversubscribed funding round. The round was led by California-based Black Ops Ventures, with participation from Michigan Rise and Dug Song of Minor Capital, who is also the founder of the Song Foundation, another Michigan-based organization.

"This raise is more than a business milestone—it's a testament to what happens when strategy meets faith. In today's climate, raising capital takes grit and resilience—especially without deep networks or traditional access. By God's grace, doors have opened, and our mission is clearer than ever. Now, with capital in hand, we're building boldly toward a future where the Church isn't just surviving—but leading community transformation," Emmanuel Brown, co-founder and CEO of ChurchSpace, said in a statement.

In Detroit, ChurchSpace plans to activate underutilized church campuses as micro-logistics spaces for food distribution and retail partnerships, as well as last-mile delivery centers. To kick off its relocation, ChurchSpace will host a Detroit Pastor Meetup on July 19.

"We welcome ChurchSpace's investment in Detroit and the jobs and innovation it will bring," Detroit Mayor Mike Duggan added in the release. "Our faith community has long been a critical backbone of our neighborhoods. Through ChurchSpace's groundbreaking work, they will continue to be anchors of opportunity and resilience in our city's future."

ChurchSpace was originally founded to convert underutilized church real estate into event, meeting and commercial kitchen space to boost revenue and relieve financial burden while remaining compliant with IRS regulations for non-profits. The company participated in the inaugural cohort of the AWS Impact Accelerator for Black Founders, which included a pre-seed fundraising campaign and a $125,000 equity injection from Amazon in 2022. It was also one of two Houston companies to receive $100,000 as part of the Google for Startups Black Founders Fund that same year.

The company reports that its platform in Texas has generated up to $100,000 annually in new revenue that was reinvested into church ministries, food programs and community initiatives.

"What we built in Houston was more than technology—it was transformation. We expanded our purpose and packaged proven strategies to help churches thrive, transform communities, and even combat food insecurity," Day Edwards, co-founder and president of ChurchSpace, added in the statement. "Now, with prayer and the support of our team and investors, we're bringing that same impact to Detroit—to help churches, communities, and small businesses redefine pulpits and rediscover communal possibilities."

Houston healthtech leader launches clinical trial for innovative anxiety-treating device

making waves

Houston-based Nexalin Technology’s proprietary neurostimulation device will move forward with a new clinical trial evaluating its treatment of anxiety disorders and chronic insomnia in Brazil.

The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices have been shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria university hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia, according to a news release.

“Brazil is an important emerging market for mental health innovation, and this collaboration marks our first IRB-approved study in the region,” Mike White, CEO of Nexalin, said in the release.

The study will be led by Dr. Andre Russowsky Brunoni, who specializes in neuromodulation and interventional psychiatry. He currently serves as director of the interventional psychiatry division at IPq-HCFMUSP and this summer will join UT Southwestern in Dallas and its Peter O’Donnell Jr. Brain Institute as a professor of psychiatry.

The Phase II study plans to enroll 30 adults in São Paulo and assess the efficacy of Nexalin’s non-invasive deep intracranial frequency stimulation (DIFS™) of the brain in reducing anxiety symptoms and improving sleep quality, according to the company. Using the Hamilton Anxiety Rating Scale (HAM-A), the trial’s goal is a reduction in anxiety symptoms, and assessments of sleep onset latency, total sleep time, overall sleep quality, depressive symptoms and clinical impression of improvement. The company plans to share results in a peer-reviewed scientific journal.

“Anxiety and insomnia are very common conditions that often occur together and cause significant distress,” Brunoni added in the news release. “In this study, we are testing a new, non-invasive brain stimulation technology that has shown promising results in recent research. Our goal is to offer a safe, painless, and accessible alternative to improve people’s well being and sleep quality.”

The Nexalin Gen-2 15-milliamp neurostimulation device has been approved in China, Brazil, and Oman.

The company also enrolled the first patients in its clinical trial at the University of California, San Diego, in collaboration with the VA San Diego Healthcare System for its Nexalin HALO, which looks to treat mild traumatic brain injury and post-traumatic stress disorder in military personnel and the civilian population. It also recently raised $5 million through a public stock offering. Read more here.
