Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its second Houston cohort this summer.

This year, the incubator grew to include its largest number of concurrent supported fellows, with 88 companies currently being supported nationally. In total, Activate has supported 296 fellows who have created 236 companies. Those companies have raised over $4 billion in follow-on funding, according to Activate. In Houston, it has supported several Innovation Awards finalists, including Solidec, Bairitone Health and Deep Anchor Solutions. It is led locally by Houston Managing Director Jeremy Pitts.

EnergyTech Nexus

Cleantech startup hub EnergyTech Nexus' mission is to accelerate the energy transition by connecting founders, investors and industrial stakeholders and helping to develop transformative companies, known as "thunderlizards."

The hub was founded in 2023 by CEO Jason Ethier, Juliana Garaizar and Nada Ahmed. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, EarthEn Energy and Solidec—many of which are current or past Innovation Awards finalists. This year Energy Tech Nexus launched its COPILOT Accelerator, powered by Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory (NREL). COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. Energy Tech Nexus also launched its Liftoff fundraising program, its Investor Program, and a "strategic ecosystem partnership" with Greentown Labs.

Greentown Labs

Climatetech incubator Greentown Labs offers its community resources and a network to climate and energy innovation startups looking to grow. The collaborative community offers members state-of-the-art prototyping labs, business resources and access to investors and corporate partners. The co-located incubator was first launched in Boston in 2011 before opening in Houston in 2021.

Greentown has seen major changes and activity this year. In February, Greentown announced Georgina Campbell Flatter as its new CEO, along with a new Board of Directors. In July, it announced Lawson Gow as its Head of Houston, a "dedicated role to champion the success of Greentown Houston’s startups and lead Greentown’s next chapter of impact in the region," according to Greentown. It has since announced numerous new partnerships, including those with Energy Tech Nexus, Los Angeles-based software development firm Nominal, to launch the new Industrial Center of Excellence; and Houston-based Shoreless, to launch an AI lab onsite. Greentown Houston has supported 175 startups since its launch in 2021, with 45 joining in the last two years. Those startups include the likes of Hertha Metals, RepAir Carbon, Solidec, Eclipse Energy (formerly GoldH2) and many others.

Healthtech Accelerator (TMCi)

The Healthtech Accelerator, formerly TMCx, focuses on clinical partnerships to improve healthcare delivery and outcomes. Emerging digital health and medical device startups that join the accelerator are connected with a network of TMC hospitals and seasoned advisors that will prepare them for clinical validation, funding and deployment.

The Healthtech Accelerator is part of Texas Medical Center Innovation, which also offers the TMCi Accelerator for Cancer Therapeutics. The Healthtech Accelerator named its 19th, and latest, cohort of 11 companies last month.

Houston startup raises $6M to scale home-based healthcare platform

fresh funding

As healthcare systems race to expand care beyond hospitals and into the home, investors are placing bigger bets on the infrastructure needed to make that shift possible.

This month, Rosarium Health announced it has raised $6 million in seed funding led by Kalos Ventures, with participation from ResilienceVC, Rock Health Capital, Symphonic Capital, Black Tech Nations Ventures and others.

The investment will help the Houston-based startup continue to build its platform, which features a national network of 800-plus clinicians and 3,000-plus contractors to coordinate home accessibility upgrades and modifications for seniors and people living with disabilities.

For founder and CEO Cameron Carter, the company’s mission grew out of firsthand caregiving experiences.

“From my own personal caregiving experiences, I realized that the benefits exist on paper, but not in reality,” Carter said in a news release. “Families are being left to figure out the paperwork and installations all on their own, which shouldn’t be how this works.”

While Medicare Advantage and Medicaid plans have expanded coverage for home-based services and accessibility modifications, the logistics behind delivering those services often remain fragmented.

Rosarium’s platform coordinates the entire process, from clinical assessments and referrals to contractor management, documentation, reimbursement and installation.

“A clinician can document that a home isn’t safe and a plan can approve a benefit, but there’s no one that’s responsible for making sure the work actually gets done,” Carter says. “We built the missing piece.”

The company was founded in 2021 as Rose Health and was a 2023 participant in the Texas Medical Center’s Accelerator for HealthTech program. It has scaled quickly, building a network of more than 800 clinicians and 3,000 contractors across 34 states.

Rosarium is currently in-network for 1.2 million Medicare and Medicaid lives, with projected coverage expected to reach nearly 4 million by the end of the year, according to the release.

“We’re excited to back Cameron because he and the team at Rosarium are building the infrastructure healthcare needs right now to make the home a safe and comfortable place of care,” Kate Ballinger, investor at Kalos Ventures, added in the release.

As part of the recent investment, Ballinger will join Rosarium’s board of directors.

With eyes on the future, Rosarium plans to grow its partnerships with Medicaid and Medicare Advantage plans, including CalViva and Community Health Plan of Imperial Valley, strengthening its presence in California while expanding access to underserved communities.

Additionally, Carter predicts that home-based healthcare will be part of a broader transformation happening across the industry.

“There’s a growing recognition that health outcomes are shaped by what happens in the home,” he said in the release. “The future of healthcare isn’t just treating people after something goes wrong. It’s creating environments that help prevent those problems in the first place.”

Houston business mogul Tilman Fertitta acquires Caesars in $17.6B deal

Money Moves

Houston billionaire Tilman Fertitta may currently be serving as America’s ambassador to Italy, but his company is as busy as ever. Fresh off its move to revive the Houston Comets WNBA franchise, his company, Fertitta Entertainment, has announced a $17.6 billion deal to acquire Caesars Entertainment, Inc.

Speculation about the deal has been circulating since at least March, according to various media reports. The deal combines Fertitta’s well-known Golden Nugget casino brand with all of the properties in the Caesars’ portfolio, including Las Vegas hotels Caesars Palace, Harrah's, Paris Las Vegas, Planet Hollywood, Horseshoe, The LINQ Hotel, Flamingo, and The Cromwell.

Overall, the combined company will include 60 domestic casino resorts and gaming facilities; online gaming including sports betting, iCasino, and Caesar’s online poker platform; retail sports betting at over 200 third-party locations through the William Hill brand; and over 550 Fertitta Entertainment outlets, including more than 450 Landry's full-service restaurants across America. The companies will combine their loyalty programs, Caesars Rewards, Golden Nugget's 24 Karat Select Club, and Landry's Select Club.

The terms will see Caesars’ shareholders receive $31 per share. Fertitta Entertainment will also acquire approximately $11.9 billion of Caesars' outstanding debt.

The transaction will be financed through a combination of equity contributed by Fertitta Entertainment, assumed Caesars' debt, and new committed debt financing arranged by a group consisting of 10 banks. It is subject to approval by Caesars’ shareholders and government regulators.

Fertitta Entertainment is the Houston-based company behind a diverse array of hospitality businesses, including The Golden Nugget, The Post Oak Hotel, River Oaks District, the Kemah Boardwalk, and Houston’s Downtown Aquarium.

It also operates a number of prominent restaurant brands, including Mastro's Restaurants, Del Frisco's Double Eagle Steakhouse, Morton's The Steakhouse, The Palm, McCormick & Schmick's, Landry's Seafood House, The Oceanaire Seafood Room, and Saltgrass Steak House.

4 Houston-area institutions get $8M for cancer research facilities

fighting cancer

Cancer research capabilities in the Houston area just got an $8 million boost.

On Wednesday, May 20, the Cancer Prevention and Research Institute of Texas (CPRIT) awarded $8 million in grants to institutions in Houston and Bryan for the creation or expansion of so-called “core” cancer research facilities.

“Core facilities provide shared access to advanced technology, equipment, and scientific expertise that may not be available at every institution,” CPRIT says. “These core facilities are vital to not only cancer research but also to the study of diseases beyond cancer.”

Houston-area recipients of these $2 million grants are:

  • A facility at the University of Texas Health Science Center for preclinical support of cancer researchers in Texas to evaluate new safe, effective drugs and drug combinations.
  • The Accelerator for Cancer Therapeutics, operated by Houston’s Texas Medical Center Foundation. The accelerator helps researchers and startups move innovative cancer treatments from the lab to clinical trials.
  • Rice University’s Genetic Design & Engineering Center in Houston. The center enables researchers to collaborate on studies of custom DNA for cancer treatment.
  • A facility at the Texas A&M University System’s Health Science Center in Bryan that aims to speed up the development of cancer therapies.

In addition to those grants, the University of Texas M.D. Anderson Cancer Center, Methodist Hospital Research Institute, Baylor College of Medicine, and Rice University shared $21 million to recruit cancer researchers from other institutions.

The largest of those grants—totalling $4 million—went to M.D. Anderson for the recruitment of renowned cancer researcher Andre Nussenzweig from the National Institutes of Health. His research focuses on how DNA damage and faulty DNA repairs lead to cancer.

Here are the totals for the other CPRIT grants awarded in the Houston area:

  • $12.8 million to Houston-based Indapta Therapeutics for the development of an off-the-shelf therapy that naturally kills cancer cells, combined with an immunity-targeting agent for a type of leukemia.
  • $11.1 million to MD Anderson, including $5 million for a statewide platform to improve long-term health outcomes in adolescents and young adults who survived cancer.
  • $8.4 million to Baylor College of Medicine, including $4.8 million for two training programs for cancer researchers.
  • $6.25 million to UT Health Houston, including $4 million for a biomedical informatics and genomics training program for cancer researchers.
  • $4.4 million to the Texas A&M Health Science Center’s Houston campus, including $2.4 million for a cancer therapeutics training program.
  • $2.75 million to Rice, including $250,000 for a study of ovarian cancer.
  • $2 million to Houston-based March Biosciences for the development of a targeted therapy for treating T-cell lymphoma.
  • $1.15 million to the University of Houston, including $900,000 for a platform for detection of lung cancer.
  • $900,000 to Texas A&M in Bryan to conduct clinical drug trials in rural and underserved communities around the state.
  • $800,000 to Houston- and Israel-based Xerient Pharma for the development of an oral form of a cell-protecting drug called amifostine to protect the upper GI tract from radiation damage during pancreatic cancer treatment.
  • $659,000 to Missouri City-based OmniNano Pharmaceuticals for the development of a two-drug combination to treat the most common form of pancreatic cancer.
  • $250,000 to the University of Texas Medical Branch at Galveston for a novel therapeutic to prevent colitis-related colorectal cancer.
