Conroe-based Hertha Metals, a producer of substantial steel, hauled in more than $17 million in venture capital from Khosla Ventures, Breakthrough Energy Fellows, Pear VC, Clean Energy Ventures and other investors.

The money was put toward the construction and the launch of its 1-metric-ton-per-day pilot plant in Conroe, where its breakthrough in steelmaking has been undergoing tests. The company uses a single-step process that it claims is cheaper, more energy-efficient and equally as scalable as conventional steelmaking methods. The plant is fueled by natural gas or hydrogen.

The company, founded in 2022, plans to break ground early this year on a new plant. The facility will be able to produce more than 9,000 metric tons of steel per year. Continue reading.

Houston digital health platform Koda closes $7 million funding round

fresh funding

Houston-based digital advance care planning company Koda Health has closed an oversubscribed $7 million series A funding round.

The round, led by Evidenced, with participation from Mudita Venture Partners, Techstars and Texas Medical Center, will allow the company to scale operations and expand engineering, clinical strategy and customer success, according to a news release.

“This funding allows us to create more goals-of-care product lines, expand our national footprint, and bring goal-concordant care to millions more patients and families," Tatiana Fofanova, co-founder and CEO of Koda Health, said in the release.

Koda Health, which was born out of the TMC's Biodesign Fellowship in 2020, has seen major growth this year and said it now supports more than 1 million patients nationwide. The company integrated its end-of-life care planning platform with Dallas-based Guidehealth in April and with Epic Systems in July. Users of Epic's popular Mychart system and Guidehealth's clinically integrated networks can now document and share their care preferences, goals and advance directives for health systems using Koda Health's platform. It also has partnerships with Cigna, Privia and Memorial Hermann.

The company shared that the recent series A "marks a pivotal moment," as it has secured investments from influential leaders in the healthcare and venture capital space.

“Koda is the only company combining technology and service to deliver comprehensive solutions that help health plans, providers, and health systems scale goals-aligned care. With satisfied customers expanding their partnerships and policy shifts reinforcing the need for patient-centered care that also contains costs, we couldn’t be more excited to support the Koda team and their vision,” Sean Glass, managing partner at Evidenced, said in the release.

According to the company, a recent peer-reviewed study with Houston Methodist ACO showed that the platform can have a major impact on palliative care results and costs. The findings showed:

  • 79 percent reduction in terminal hospitalizations
  • 20 percent decrease in inpatient length of stay
  • 51 percent increase in hospice use among decedents
  • Nearly $9,000 in average savings per patient

“Patients long for clarity, families deserve peace of mind, and providers demand ease of use,” Dr. Desh Mohan, chief medical officer of Koda Health, added in the release. “At Koda, we make it possible to deliver all three — transforming Advance Care Planning into a compassionate, ongoing dialogue that honors patients and supports families every step of the way.”

Koda Health also closed an oversubscribed seed round for an undisclosed amount last year, with investments from AARP, Memorial Hermann Health System and the Texas Medical Center Venture Fund. Read more here.

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 startup secures $22.5M to innovate cell therapy to fight cancer

fresh funding

A promising cell therapy company has raised its latest funding round — to the tune of $22.5 million.

Indapta Therapeutics, which has a dual headquarters in Houston and Seattle, is a clinical stage biotechnology and next-generation cell therapy company focused on the treatment of cancer and autoimmune diseases. The company announced it has closed a $22.5 million round of new financing to accelerate the clinical development of its differentiated allogeneic Natural Killer cell therapy.

"This funding will enable us to generate significant additional data in our ongoing trial of IDP-023 in cancer as well as initial data from our first trial in autoimmune disease," Mark Frohlich, Indapta’s CEO, says in a news release.

Indapta has completed enrollment in the safety run-in portion of the Phase 1 clinical trial of IDP-023 in Non-Hodgkin’s Lymphoma and Multiple Myeloma, according to the company. The patients received up to three doses of IDP-023 without and with interleukin (IL)-2.

Completing the round were current investors RA Capital Management, Bayer's impact investment arm Leaps, Vertex Ventures HC, Pontifax, and the Myeloma Investment Fund, the venture philanthropy subsidiary of the Multiple Myeloma Research Foundation. Earlier in December, Indapta announced a collaboration with Sanofi to explore the combination of its allogeneic g-NK cell therapy IDP-023 with Sanofi’s CD38 that targets the monoclonal antibody, Sarclisa (isatuximab).

"Preliminary results of IDP-023 in cancer are encouraging and we look forward to initiating our Phase 1 trial for multiple sclerosis in Q1 2025,” Frohlich continues. “This financing, together with our recently announced collaboration with Sanofi, highlights the promise of our differentiated platform.”

Also in August, Indapta announced a FDA clearance of its IND of IDP-023 in combination with ocrelizumab in progressive MS.

Houston company secures $12M series A for decarbonization plant

money moves

A fresh $12 million round of funding will enable Houston-based Citroniq Chemicals to propel planning, design, and construction of its first decarbonization plant.

An unidentified multinational energy technology company led the series A round, with participation from Houston-based Lummus Technology Ventures and cooperation from the State of Nebraska. The Citroniq plant, which will produce green polypropylene, will be located in Nebraska.

“Lummus’ latest investment in Citroniq builds on this progress and strengthens our partnership, working together to lower carbon emissions in the plastics industry,” Leon de Bruyn, president and CEO of Lummus Technology, says in a news release.

Citroniq is putting together a decarbonization platform designed to annually capture 2 million metric tons of greenhouse gas emissions at each plant. The company plans to invest more than $5 billion into its green polypropylene plants. Polypropylene is a thermoplastic resin commonly used for injection molding.

The series A round “is just the first step in our journey towards building multiple biomanufacturing hubs, boosting the Nebraska bioeconomy by converting local ethanol into valuable bioplastics,” says Kelly Knopp, co-founder and CEO of Citroniq.

Citroniq’s platform for the chemical and plastics industries uses technology and U.S.-produced ethanol to enable low-cost carbon capture. Citroniq’s process permanently sequesters carbon into a useful plastic pellet.

Lummus Technology licenses process technologies for clean fuels, renewables, petrochemicals, polymers, gas processing and supply lifecycle services, catalysts, proprietary equipment, and digital transformation.

Report: Houston's VC trends so far in 2024 and what to watch for the rest of the year

by the numbers

Houston-based geothermal company Fervo Energy accounted for more than half of the venture capital raised by Houston-area startups in the first quarter of 2024.

The region’s VC haul in the first quarter totaled $462.4 million, according to the PitchBook-NCVA Venture Monitor. That’s up from $290.4 million during the same period in 2023 and from $285.8 million in the fourth quarter of last year. Click here to see the Q1 rounds as reported by InnovationMap.

Fervo’s latest funding round, announced in February, represented $244 million (52 percent) of the region’s VC total for the first quarter of 2024.

A report released in March by PitchBook indicated that VC funding last year for geothermal power reached $431 million across 21 deals. As of late February 25 — four days ahead of the Fervo announcement — $165.5 million in VC funding had been pumped into the geothermal sector this year, according to PitchBook.

“The recent VC deal activity with the geothermal power sector underscores a vibrant and evolving market, but still one that garners far less VC than other renewables,” says the report.

In all, Houston-area startups made 38 VC deals in this year’s first quarter, the PitchBook-NVCA Venture Monitor says. That’s down from 42 in the fourth quarter of 2023 and 43 in the first quarter of 2023. Nationwide, the deal count fell sharply in the first quarter of 2024 vs. the first and fourth quarters of last year.

The PitchBook-NVCA Venture Monitor report shows that nationwide, the $36.6 billion in VC investments recorded during the first quarter of 2024 “remained relatively on pace with the past year.”

“However, it would be a mistake to hyperfocus on the results of a single quarter whose results were a bit farther left on the bell curve than usual. The venture capital … business cycle effectively reset in recent years, and as of early 2024, it still appears to be searching for its level,” says the report.

“It is too early to tell where 2024 is going, but the game is on, and America’s VCs are ready for it,” the report adds. “In 2022, our world changed; in 2023, we accepted it was not changing back; and in 2024, we are building what is next.”

In a bit of good news for the Houston area, the report cites cleantech/energy as one of two sectors that venture capitalists should not overlook. The other sector: cybersecurity.

But in a bit of not-so-good news for the region, the report notes a slowdown in VC deals in the healthcare sector over the past two years in the wake of “pandemic-fueled capital exuberance.”

“Yet the healthcare sector differentiates itself from the rest of the market by demonstrating many unmet needs that could have a profound impact on society, particularly around disease diagnosis and treatment,” the report goes on to say. “On top of the immense opportunity set for disruption within healthcare, investor enthusiasm around AI adoption in drug development further speaks to the demand for better solutions in biotech through groundbreaking innovations.”

Houston Methodist awarded $4M grant to recruit head of Neal Cancer Center

new hire

Armed with a $4 million state grant, the Houston Methodist Academic Institute has recruited a renowned expert in ovarian and endometrial cancer research to lead the Dr. Mary and Ron Neal Cancer Center.

The grant, provided by the Cancer Prevention and Research Institute of Texas, enabled the institute to lure Dr. Daniela Matei away from Northwestern University’s Feinberg School of Medicine in Chicago. There, she is the Diana Princess of Wales Professor in Cancer Research and chief of the Division of Reproductive Science in Medicine.

Matei will succeed Dr. Jenny Chang, who was hired last year to run the Houston Methodist Academic Institute.

At the Neal Cancer Center, located in the Texas Medical Center complex, oncologists work on innovations in cancer research, treatment, and technology. The center opened in 2021 after the Neals donated $25 million to expand Houston Methodist’s cancer research capabilities. It handles about 7,000 new cases each year involving more than two dozen types of cancer.

U.S. News & World Report puts Houston Methodist Hospital at No. 19 among the country’s best hospitals for cancer care, two spots below Chicago’s Northwestern Memorial Hospital. The University of Texas MD Anderson Cancer Center in Houston sits at No. 1 on the list.

Matei’s research related to ovarian and endometrial cancer holds the potential to benefit tens of thousands of American women. The American Cancer Society estimates:

  • 21,010 women in the U.S. will be diagnosed with ovarian cancer, and 12,450 women will die from it.
  • 68,270 women in the U.S. will be diagnosed with endometrial cancer, and 14,450 women will die from it.

Matei is leaving Northwestern in the wake of widespread cuts in federal funding for medical research. The National Institutes of Health (NIH) has canceled or frozen tens of millions of dollars in grants for Northwestern, the Wall Street Journal reports, and the university has been plugging the gaps with its own money.

“The university is totally keeping us on life support,” Matei told the newspaper last year. “The big question is for how long they can do this.”

According to the Wall Street Journal, Matei’s $5 million NIH grant supporting 69 cancer trials has been caught up in the federal funding chaos, so Northwestern stepped in to cover trial expenses such as nurses’ salaries and diagnostic procedures.

Trial participants include some patients with rare, incurable tumors who are undergoing experimental treatments aligned with the genetics of their condition, the newspaper says.

“It’s certainly a life-and-death situation for cancer patients on these trials,” Matei said in 2025.

Matei is among the beneficiaries of more than $15 million in grants approved February 18 by CPRIT’s board. The grants went toward recruiting five cancer researchers to institutions in Texas.

One of those grants, totaling $1.5 million, went to the University of Houston to recruit Akash Gupta, a research scientist at MIT’s Koch Institute for Integrative Cancer Research. The remaining grants went to recruit scientists to The University of Texas at Dallas and The University of Texas Southwestern Medical Center.

Rice University lands $14M state grant to open Center for Space Technologies

on a mission

Rice University’s Space Institute soon will be home to the newly created Center for Space Technologies.

On Feb. 17, the Texas Space Commission approved a nearly $14.2 million grant for the Rice project. The Center for Space Technologies will target:

  • Research and development
  • Technology transfer and innovation
  • Statewide partnerships
  • Workforce development training
  • Space-focused education programs

The goal of the new center “is to fulfill an articulated need for research, workforce development, and industry collaboration,” said Kemah communications and marketing executive Gwen Griffin, chair of the commission.

State Rep. Greg Bonnen, a Friendswood Republican, authored the bill that set up the Texas Space Commission.

Since being authorized in 2023, the commission has funded 24 projects, with Rice and Houston-area companies accounting for nearly $75 million in grants to back space-related initiatives.

The grant to Rice brings the TSC's total investment to $150 million, fully committing the entire state appropriation from the Texas Legislature in 2023.

Other local companies that have received grants over the years include Aegis Aerospace, Axiom Space, Intuitive Machines, Starlab Space and Venus Aerospace.

The commission also awarded $7 million to Blue Origin earlier this month. See a list of the 24 awards here.

Waymo self-driving robotaxis have officially launched in Houston

Waymo has arrived

Waymo will begin dispatching its robotaxis in four more cities in Texas and Florida, expanding the territory covered by its fleet of self-driving cars to 10 major U.S. metropolitan markets.

The move into Dallas, Houston, San Antonio and Orlando, Florida, announced Tuesday, February 24, widens Waymo's early lead in autonomous driving while rival services from Tesla and the Amazon-owned Zoox are still testing their vehicles in only a few U.S. cities.

In contrast, Waymo's robotaxis already provide more than 400,000 weekly trips in the six metropolitan areas where they have been transporting passengers: Phoenix, the San Francisco Bay Area, Los Angeles, Miami, Atlanta, and Austin, Texas.

Waymo operates its ride-hailing service through its own app in all the U.S. cities except Atlanta and Austin, where its robotaxis can only be summoned through Uber's ride-hailing service.

The expansion into four more markets marks a significant step toward Waymo's goal to surpass 1 million weekly paid trips by the end of 2026. Without identifying where its robotaxis will be available next, Waymo is targeting a list of eight other cities that include Las Vegas, Washington, Detroit and Boston while signaling its first overseas availability is likely to be London.

To help pay for more robotaxis, Waymo recently raised $16 billion as part of the financial infusion that puts the value of the company at $126 billion. The valuation fueled speculation that Waymo may eventually be spun off from its corporate parent Alphabet, where it began as a secret project within Google in 2009.

Although Waymo is opening up in four more cities, its robotaxis initially will only be made available to a limited number of people with its ride-hailing app in Dallas, Houston, San Antonio and Orlando before the service will be available to all comers in those markets.
