Houston-founded multifamily service provider Spruce has raised a $26 million series B round of funding. Additionally, the company has named seasoned technology executive and board member Steven Pho as CEO. His previous experience includes Favor Delivery and RetailMeNot. Former CEO and founder, Ben Johnson, will transition to president.

“For the past two years, I’ve been able to guide Spruce as a board member and am honored to continue to do that as CEO,” says Pho in a news release. “Ben’s vision for Spruce ensured the company’s incredible growth to date, as well as the outsized positive impact on local economies and small businesses Spruce partners with across the country. I am excited to continue to partner with him as he transitions to President of the company. ”

The series B round was led by Sweat Equity Partners, with participation from SoftBank Corp., Mercury Fund, Fitz Gate Ventures, Seamless Capital, Raven One Ventures, and New Age Ventures. The funding will be used to grow the company's team to support expansion. Spruce reportedly plans to nearly double its headcount.

“We believe Spruce has established the right formula for working with local businesses, consumers, and rental properties alike,” says Manish Narula of SoftBank Corp. “We are looking forward to Spruce’s continued growth as it scales with this latest investment round.”

Spruce has raised $40 million to date, including its $8 million series A, which was led by Houston-based Mercury Fund in 2020. The company, which was founded as Apartment Butler, rebranded and relocated its HQ to Austin a couple years ago.

  • employ two to 20 people
  • are located in the north, central east, or south Texas regions
  • have annual revenues between $100,000 to $3 million

The grant program was established to help business owners create premium wage jobs and reward diverse-led businesses throughout the state of Texas. Since its launch in early 2021, Founders First CDC has awarded more than $400,000 to minority and underserved business owners throughout the United States.

“With the rising cost of living, it can be challenging for families let alone business owners to stay afloat, particularly when it costs them more to provide goods and services for their consumers,” says Shaylon Scott, executive director of Founders First, in a news release. “We are happy to be able to invest money and resources in hard working business owners throughout Texas to help them thrive, even during uncertain economic times. Investing in diverse entrepreneurs is not only an impactful way to create jobs but is a pivotal way to close the general wealth gap in underserved communities.”

Qualified business owners, particularly those in the Dallas-Ft. Worth, Houston, Austin, and San Antonio markets can learn more and apply online.

Houston suburb ranks as No. 3 best place to retire in Texas

Rankings & Reports

Texas retirees on the hunt for the right place to settle down and enjoy their blissful retirement years will find their haven in the Houston suburb of Pasadena, which just ranked as the third-best city to retire statewide.

A new study conducted by the research team at RetirementLiving.com, "The Best Cities to Retire in Texas," compared the affordability, safety, livability, and healthcare access for seniors across 31 Texas cities with at least 90,000 residents.

Wichita Falls, about 140 miles northwest of Dallas, claimed the top spot as the No. 1 best place to retire in Texas.

The senior living experts said Pasadena has the best healthcare access for seniors in the entire state, and it ranked as the No. 8 most affordable city on the list.

"Taking care of one’s health can be stressful for seniors," the report said. "Harris County, where [Pasadena is] located, has 281.1 primary care physicians per 1,000 seniors — that’s almost 50-fold the statewide ratio of 5.9 per 1,000."

Pasadena ranked 10th overall for its livability, and ranked 25th for safety, the report added.

Meanwhile, Houston proper ranked as the No. 31 best place to retire in Texas, but its livability score was the 7th best statewide.

Seven of the Lone Star State's top 10 best retirement locales are located in the Dallas-Fort Worth Metroplex: Carrollton (No. 2), Plano (No. 4), Garland (No. 5), Richardson (No. 6), Arlington (No. 7), Grand Prairie (No. 8), and Irving (No. 9). McAllen, a South Texas border town, rounded out the top 10.

RetirementLiving said Carrollton has one of the lowest property and violent crime rates per capita in Texas, and it ranked as the No. 5 safest city on the list. About 17 percent of the city's population is aged 65 or older, which is higher than the statewide average of just 14 percent.

The top 10 best place to retire in Texas in 2026 are:

  • No. 1 – Wichita Falls
  • No. 2 – Carrollton
  • No. 3 – Pasadena
  • No. 4 – Plano
  • No. 5 – Garland
  • No. 6 – Richardson
  • No. 7 – Arlington
  • No. 8 – Grand Prairie
  • No. 9 – Irving
  • No. 10 – McAllen

Rice University lands $18M to revolutionize lymphatic disease detection

fresh funding

An arm of the U.S. Department of Health and Human Services has awarded $18 million to scientists at Rice University for research that has the potential to revolutionize how lymphatic diseases are detected and help increase survivability.

The lymphatic system is the network of vessels all over the body that help eliminate waste, absorb fat and maintain fluid balance. Diseases in this system are often difficult to detect early due to the small size of the vessels and the invasiveness of biopsy testing. Though survival rates of lymph disease have skyrocketed in the United States over the last five years, it still claims around 200,000 people in the country annually.

Early detection of complex lymphatic anomalies (CLAs) and lymphedema is essential in increasing successful treatment rates. That’s where Rice University’s SynthX Center, directed by Han Xiao and Lei Li, an assistant professor of electrical and computer engineering, comes in.

Aided by researchers from Texas Children’s Hospital, Baylor College of Medicine, the University of Texas at Dallas and the University of Texas Southwestern Medical Center, the center is pioneering two technologies: the Visual Imaging System for Tracing and Analyzing Lymphatics with Photoacoustics (VISTA-LYMPH) and Digital Plasmonic Nanobubble Detection for Protein (DIAMOND-P).

Simply put, VISTA-LYMPH uses photoacoustic tomography (PAT), a combination of light and sound, to more accurately map the tiny vessels of the lymphatic system. The process is more effective than diagnostic tools that use only light or sound, independent of one another. The research award is through the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics and pHenotyping Technologies (LIGHT) program, part of the U.S. HHS, which saw the potential of VISTA-LYMPH in animal tests that produced finely detailed diagnostic maps.

“Thanks to ARPA-H’s award, we will build the most advanced PAT system to image the body’s lymphatic network with unprecedented resolution and speed, enabling earlier and more accurate diagnosis,” Li said in a news release.

Meanwhile, DIAMOND-P could replace the older, less exact immunoassay. It uses laser-heated vapors of plasmonic nanoparticles to detect viruses without having to separate or amplify, and at room temperature, greatly simplifying the process. This is an important part of greater diagnosis because even with VISTA-LYMPH’s greater imaging accuracy, many lymphatic diseases still do not appear. Detecting biological markers is still necessary.

According to Rice, the efforts will help address lymphatic disorders, including Gorham-Stout disease, kaposiform lymphangiomatosis and generalized lymphatic anomaly. They also could help manage conditions associated with lymphatic dysfunction, including cancer metastasis, cardiovascular disease and neurodegeneration.

“By validating VISTA-LYMPH and DIAMOND-P in both preclinical and clinical settings, the team aims to establish a comprehensive diagnostic pipeline for lymphatic diseases and potentially beyond,” Xiao added in the release.

The ARPA-H award funds the project for up to five years.
