Deloitte just unveiled the fastest-growing technology companies in North America — and four businesses from Houston made the cut.

For the 29th year, 2023 Technology Fast 500 ranked top tech, media, telecommunications, life sciences, and energy technology companies based on fiscal year revenue growth from 2019 to 2022. While no Houston business was able to break into the top 100, four did make the cut for this year's list.

“It is great to see Houston represented alongside established technology hubs on this year’s Fast 500 list,” Amy Chronis, vice chair, US Energy and Chemicals Leader and Houston managing partner at Deloitte, says in a statement. “Houston is planting seeds for future innovation, and the companies named to this year’s list confirm our city’s value proposition as an innovative community. We look forward to this growth continuing in the future and extend our congratulations to this year’s Houston winners.”

The four Houston companies that make the 2023 list are:

  • Direct Digital Holdings at No. 108 with 1,325 percent growth
  • Liongard at No. 208 with 680 percent growth
  • NatGasHub.com at No. 356 with 364 percent growth
  • P97 Networks at No. 506 with 225 percent growth

Thirty Texas companies made the list of the 541 ranked, making it the fourth most concentrated hub on the list behind the Bay Area, Tri-State Area, and New England. The companies on the list reported a revenue growth ranging from 201 percent to 222,189 percent over the three-year time frame from 2019 to 2022. The average growth rate was 1,934 percent and a median growth rate of 497 percent.

“Each year, we look forward to reviewing the progress and innovations of our Technology Fast 500 winners," Paul Silverglate, vice chair, Deloitte LLP and U.S. technology sector leader, says in the release. "This year is especially celebratory as we expand the number of winners to better represent just how many companies are developing new ideas to progress our society and the world, especially during a slow economy. While software and services and life sciences continue to dominate the top 10, we are encouraged to see other categories making their mark."

Software dominated the industry breakdown with 57 percent of the companies working in that field. However, the top company for 2023 was Vir Biotechnology Inc., a life science company that developed a COVID-19 treatment. Vir was also the top company in 2022.

Last year, only one Houston company made the list. At No. 372 Onit reported a revenue increase of 369 percent. The company also made the 2021 list, along with Graylog and Enercross.

Amid international VC decline, here's what Houston startups received investment, grant funding last quarter

seeing green

The second quarter of 2023 looked a lot like the first when it came to venture capital funding for Houston companies. The whole country — affected by inflation, geopolitical instability, and other factors — has seen a trying time for investment opportunities.

Houston's performance is far from unique. Globally, VC funding is down — a reported 18 percent from Q1 to Q2, per Crunchbase. Year over year, that's a 49 percent decrease from 2022's Q2.

According to InnovationMap reporting, 10 Houston-based, Houston-founded, or soon-to-be Houston-headquartered companies announced VC or grant funding between April and June. Here's a roundup of these second quarter deals — click on each story to read more.

For the second time in just over a year, a Houston business that provides mobile commerce and digital marketing to the mobility and fuel industries has raised $40 million.

P97 Networks, which has developed a cloud-based mobile commerce platform that helps brands securely do business with customers, announced that it has closed its series C round at $40 million. The equity financing round was led by Portage and included participation from existing investors. The fresh funding will go to support growth strategy.

Podcast: Houston home tech startup SmartAC.com raises $22M to grow sales

A Houston startup that combines unique sensor technology with software analysis has raised its next round of funding to — according to Founder and CEO Josh Teekell — turbocharge its sales.

SmartAC.com launched in 2020, emerging from stealth with $10 million raised in a series A. Over the past almost three years, the company has firmed up its hardware, developed its software, and pivoted slightly from selling directly to consumers to adopting a B2B approach.

Now, Teekell says he's focused on turbocharging sales to these contractors, and he's going to do that with the funding raised in the series B round that closed this month. He says the company will also grow its team that goes out to deploy the technology and train the contractors on the platform.

"This funding really buys us a couple years of runway through the end of next year and allows us to focus on getting to cash flow breakeven, which is right around our wheelhouse of our abilities here in the next 12 months," Teekell says. "In general, we've accomplished everything we'd be able to accomplish on the hardware side, and now it's just about deployment."

The $22 million SmartAC.com has raised came from local investors. Teekell, who hasn't announced the full list of the round's investors, explains that while traditionally startups might have more opportunity on the coasts for raising money, it's not hard to sell Houstonians on the benefits of SmartAC.com's optimized air conditioning.

Between Bangalore and Chennai in the Indian state of Andhra Pradesh, you’ll find the town of Tirupati. It’s home to seven peaks that host a Hindu temple complex devoted to a form of Vishnu, Venkateshvara. It is also the region from which Upendra Marathi originally hails. It’s where his father, and many other family members, attended medical school.

“My father’s first job was to take care of the pilgrims,” recalls Marathi.

It's only natural that his groundbreaking Houston company would be named 7 Hills Pharma.

“That sort of selflessness and giving back, I wanted to embody it in the name of the company,” Marathi says.

Now, 7 Hills Pharma is announcing that last month, it was awarded a $13.5 million grant from the Cancer Prevention and Research Institute of Texas (CPRIT). That’s on top of more than $13 million in NIH grants, making the company the second largest recipient of SBIR/STTR grants in Texas. Continue reading.

A biotech company has landed a more than $13 million grant from the Cancer Prevention and Research Institute of Texas.

The nearly $13.3 million grant given to OncoResponse — which is relocating from Seattle to Houston, according to CPRIT's news release — will help the company develop fully human monoclonal antibodies for treatment of cancer that otherwise would not respond to immunotherapy. OncoResponse already has a partnership with MD Anderson Cancer Center, which is one of the company’s investors.

“We are thrilled to receive this recognition from CPRIT in supporting the potential of our immunotherapy candidate OR502. We greatly appreciate the additional support from our investors as we continue to make significant progress with our drug development efforts advancing immunotherapies derived from clues of Elite Responders,” says Clifford Stocks, CEO of OncoResponse, in a news release.

They say it’s all in the timing. For CellChorus, it’s all in the TIMING. That’s Time-lapse Imaging Microscopy In Nanowell Grids. TIMING is a visual AI program that evaluates cell activation, killing and movement, which allows scientists to better understand how cells function.

The technology is important to the development of novel therapies in the realms of oncology, infectious diseases, and countless other disorders and diseases. By allowing scientists to observe those maladies at their roots, it will enable them to create, and ultimately deliver new medications and other therapies faster, at lower cost, and with a higher success rate.

CellChorus is a spinoff of the Single Cell Lab at the University of Houston. Part of UH’s Technology Bridge, CEO Daniel Meyer connected with co-founder and leader of Single Cell Lab, Navin Varadarajan, through co-founder Laurence Cooper.

“The company had been established, but there were limited operations,” recalls Meyer during a phone call with InnovationMap.

That was the fall of 2020. Now, the team has just announced a $2.3 million SBIR (Small Business Innovation Research) Fast-Track grant from the National Institute of General Medical Sciences. Continue reading.

A health tech startup that just collected $1.7 million in pre-seed funding aims to eventually plant its headquarters in Houston.

The startup, Rosarium Health, currently has no headquarters; its 10 employees work remotely from various locations. However, co-founder and CEO Cameron Carter — who lives in the Denver area — says the company is eyeing a future headquarters in Houston.

“We believe Houston is the best city to launch a health care startup, given the Texas Medical Center, diverse talent across health and technology, affordable living, and a city with supportive and progressive communities,” Carter tells InnovationMap. “We feel Houston offers meaningful attributes that can enable a high-growth startup to succeed and for its employees to feel safe.” Continue reading.

A Houston-based company that's developing an engine that'll enable one-hour global transportation has announced its latest investor.

Venus Aerospace released the news that Silicon Valley venture capital firm, Airbus Ventures, has joined its team of investors. The supersonic combustion engine technology — more akin to a rocket's engine than an airplane's — is revolutionary because allows for travel at a higher elevation. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally.

“Venus has developed the world’s first liquid-propellant rotating detonation rocket engine (RDRE) with a double-digit percentage increase in efficiency over standard regular engines, making the hypersonic economy possible,” says Sassie Duggleby, CEO and co-founder of Venus, in a news release. “We’re delighted to bring Airbus Ventures into the Venus family and look forward to growing our collaboration as we harness the future of hypersonic flight.” Continue reading.

money moves

For the second time in just over a year, a Houston business that provides mobile commerce and digital marketing to the mobility and fuel industries has raised $40 million.

P97 Networks, which has developed a cloud-based mobile commerce platform that helps brands securely do business with customers, announced that it has closed its series C round at $40 million. The equity financing round was led by Portage and included participation from existing investors. The fresh funding will go to support growth strategy.

"In this highly connected world, retail brands are looking for new ways to increase consumer engagement — the power of network effects in the digital world will be a key contributor to revenue growth and margins," says Donald Frieden, CEO of P97 Networks, in a news release. "With consumers of all ages further adopting mobile payment solutions, we are proud to have built the leading connected commerce and digital marketing platform for the convenience retail, energy marketing, and transportation industry."

In January of 2022, P97 raised $40 million, and, according to Crunchbase, the company has secured a total of $109 million in funding since its founding in 2012.

The company's unique platform is used by a majority of the retail fuel market in North America, per the release, with the intention of expanding further into the fleet, connected car, and EV charging markets. The technology also enables engagement and secure transactions, using tokenized payments and personalization.

"P97 has quickly established itself as a dominant mobile commerce solution for the North American retail convenience and fuel market," says Dan Ballen, partner and co-head of Portage Capital Solutions, in the release. "The company will continue to benefit from accelerating consumer adoption of mobile payments, while also leveraging its best-in-class technology to capitalize on compelling opportunities in adjacent verticals."

Toronto-based Portage is focused on the fintech and financial services sectors, and its investment derives from the recently launched Portage Capital Solutions strategy.

"We are thrilled to partner with P97 on our first Portage Capital Solutions investment and look forward to helping Don and the team drive their long-term vision," says Adam Felesky, CEO of Portage, in the release.

Houston-based mobile commerce startup secures $40M to scale its SaaS business

money moves

A Houston company that has created a mobile commerce platform for the convenience retail, fuels marketing, and automotive industries has fresh funding to support its growth.

P97 Networks has raised $40 million of venture debt financing from an affiliate of Peak Rock Capital, a leading middle-market private investment firm, according to a news release from the company.

“We will use this new capital to fund P97’s high growth initiatives, which include accelerating user adoption across our Consumer Engagement platform, Energy Transition programs for our clients, and our Mobility Services platform,” said Donald Frieden, president and CEO of P97, in the release.

Frieden says that over the past 18 months, the company has doubled the number of sites on its platform, which includes five largest energy brands in the world, and over 60,000 convenience retail sites in North America.

“With this new capital, we will continue to grow our install base and strategic partnerships," Frieden continues. "We look forward to working with Peak Rock to bring our company to its next stage of growth and further establish our position as the leading provider of mobile commerce technology in the convenience & fuel retailing industry.”

P97's last raise was a series B round in 2019 that saw contribution from Accenture. The startup's series A closed in 2014 and was led by Emerald Technology Ventures.

The company's platform operates as a payments platform as well as a digital marketing solution that prioritizes payment security and customer customization.

“P97 has become the industry standard in the convenience retail and fuel marketing industry, and we are very pleased to help the company reach its next level of scale and growth,” says Nick Basso, managing director at Peak Rock Capital. “We are excited by the compelling opportunities ahead for P97 as the market for mobile payment solutions continues to expand and gain broad adoption by consumers.”

Last year, P97 announced a partnership with Chevron that meant implementing the digital platform into more than 7,800 Chevron and Texaco retail stations across the country.

“Chevron is dedicated to providing products and services for people on the go and continuing to address their needs in the retail of the future,” says Harry Hazen, Chevron senior manager of Americas Marketing, in a 2021 press release. “Our collaboration with P97 strengthens that commitment – delivering a premium consumer experience at Chevron and Texaco locations by enabling our offerings with consistency, speed, consumer value, and security.”

Houston family's $20M donation drives neurodegeneration research

big impact

Neurodegeneration is one of the cruelest ways to age, but one Houston family is sharing its wealth to invigorate research with the goal of eradicating diseases like Alzheimer’s.

This month, Laurence Belfer announced that his family, led by oil tycoon Robert Belfer, had donated an additional $20 million to the Belfer Neurodegeneration Consortium, a multi-institutional initiative that targets the study and treatment of Alzheimer’s disease.

This latest sum brings the family’s donations to BNDC to $53.5 million over a little more than a decade. The Belfer family’s recent donation will be matched by institutional philanthropic efforts, meaning BNDC will actually be $40 million richer.

BNDC was formed in 2012 to help scientists gain stronger awareness of neurodegenerative disease biology and its potential treatments. It incorporates not only The University of Texas MD Anderson Cancer Center, but also Baylor College of Medicine, Massachusetts Institute of Technology (MIT) and Icahn School of Medicine at Mount Sinai.

It is the BNDC’s lofty objective to develop five new drugs for Alzheimer’s disease and related disorders over the next 10 years, with two treatments to demonstrate clinical efficacy.

“Our goal is ambitious, but having access to the vast clinical trial expertise at MD Anderson ensures our therapeutics can improve the lives of patients everywhere,” BNDC Executive Director Jim Ray says in a press release. “The key elements for success are in place: a powerful research model, a winning collaborative team and a robust translational pipeline, all in the right place at the right time.”

It may seem out of place that this research is happening at MD Anderson, but scientists are delving into the intersection between cancer and neurological disease through the hospital’s Cancer Neuroscience Program.

“Since the consortium was formed, we have made tremendous progress in our understanding of the molecular and genetic basis of neurodegenerative diseases and in translating those findings into effective targeted drugs and diagnostics for patients,” Ray continues. “Yet, we still have more work to do. Alzheimer's disease is already the most expensive disease in the United States. As our population continues to age, addressing quality-of-life issues and other challenges of treating and living with age-associated diseases must become a priority.”

And for the magnanimous Belfer family, it already is.

3 Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes a podcast with the founder of a new venture firm, a former astronaut and recent award recipient, and a health care innovator with fresh funding.

Zach Ellis, founder and managing partner of South Loop Ventures

Houston has a lot of the right ingredients for commercialization and scaling up companies, so when Zach Ellis moved to town to stand up a venture capital firm that made investments in diverse founders, he decided to go about it in an innovative way.

South Loop Ventures, which Ellis launched two years ago, invests in pre-seed and seed-stage startups across health care, climatetech, aerospace, sports, and fintech. While the first handful of investments, which have already been made, are into Houston-based companies, Ellis explains on the Houston Innovators Podcast that the firm plans to invest in promising companies from across the country and bring them into Houston's ecosystem to grow and scale.

"Any investor wants to feel like they are looking at the best possible investment opportunities in which to deploy capital," Ellis says on the show. "So that's reason No. 1 to cast your net as widely as possible.

"At the same time, you want to give any investment that you make greatest chances of success," he continues. "The biggest factor of success outside of the team and the capital you give them, is the customers that they can call upon. In bringing targeted companies to Houston or connecting them with Houston, you introduce the opportunity for them to achieve rapid scale and work with world-class partners very efficiently."

She flew four more times to space with STS-66, STS-96, STS-110, and more.

“I’m so grateful for all my amazing NASA colleagues who shared my career journey with me,” Ochoa says in a NASA news release. Read more.

Houston health care institutions receive $22M to attract top recruits

coming to Hou

Houston’s Baylor College of Medicine has received a total of $12 million in grants from the Cancer Prevention & Research Institute of Texas to attract two prominent researchers.

The two grants, which are $6 million each, are earmarked for recruitment of Thomas Milner and Radek Skoda. The Cancer Prevention & Research Institute of Texas (CPRIT) announced the grants May 14.

Milner, an expert in photomedicine for surgery and diagnostics, is a professor of surgery and biomedical engineering at the Beckman Laser Institute & Medical Clinic at the University of California, Irvine and the university’s Chao Family Comprehensive Cancer Center

In 2013, Milner was named Inventor of the Year by the University of Texas at Austin. At the time, he was a professor of biomedical engineering at UT. One of his major achievements is co-development of the MasSpec Pen, a handheld device that identifies cancerous tissue within 10 seconds during surgical procedures.

Skoda is a professor of molecular medicine in the Department of Biomedicine at the University of Basel and the University Hospital Basel, both in Switzerland. He specializes in developing treatments for myeloproliferative neoplasms, which are a group of blood diseases including leukemia.

Other recruitment grants provided by the institute to Houston-area organizations are:
