"The COVID-19 pandemic saw an unprecedented shift to even more screen time and interactions using remote video communication platforms," he writes. "It was also around this time that wireless virtual reality headsets were, for the first time ever, economically accessible to the consumer due to the large push of one multinational corporation. Fast forward to 2023, there are even more companies beginning to enter the market with new extended reality (XR) headsets (i.e. virtual, mixed, and augmented reality) that offer spatial computing – the ability for computers to blend into the physical worlds (amongst other things)."Read more.

A Houston software-as-a-service company has secured $39 million in financing and announced its latest upgrade to its platform.

Graylog, which has created an innovative platform for cybersecurity and IT operations, raised equity funding with participation from new investor Silver Lake Waterman and existing investors Piper Sandler Merchant Banking and Harbert Growth Partners leading the round.

“The growth we are seeing globally is a response to our team’s focus on innovation, a superior user experience, low total cost of ownership, and strong execution from our Go-To-Market and Customer Success teams,” Andy Grolnick, CEO of Graylog, says in a news release. “We expect this momentum to continue as Graylog expands its reach and raises its profile in the security market.”

Grolnick tells TechCrunch that the financing includes $9 million in a series C extension round and $30 million in “flex debt.” The company closed its series C in 2021.

In its news release, Graylog reported a 67 percent increase in new bookings as of last quarter. The company also reported the acquisition of Resurface.io’s API security platform in July, growth in Europe and Asia Pacific, and availability on AWS Marketplace among its list of recent growth opportunities.

“Graylog’s solid growth underscores the strength of the extensible Threat Detection & Incident Response platform the team has built to help customers detect and respond to cybersecurity threats and leverage advanced log management for operational effectiveness,” Shawn O’Neill, managing director and group head of Silver Lake Waterman, says in the release. “We look forward to partnering with Graylog to help enable their continued success.”

The financing was announced October 31, and today, November 1, Graylog announced version 5.2 of its platform technology for its users.

“Graylog’s product-led growth model, combined with its focus on customer success, continues to be an attractive combination that bodes well for its future," Bob Rinek, managing director with Piper Sandler Merchant Banking, says in the release. "We’re also excited about Graylog’s expansion into the API Security space to help its customers defend this vulnerable attack surface."

Originally founded in 2009 by Lennart Koopmann as an open source project, Houston-based VC firm Mercury invested in the company in 2014. Grolnick has served as CEO since 2020.

3 Houston companies make Deloitte's fastest-growing tech list

biz is booming

Three Houston companies have earned spots on this year's edition of the North American Technology Fast 500.

The three Houston honorees are:

  • Enercross, a provider of logistics software for the energy sector. It appears at No. 31 on the Fast 500 list, with revenue growth of 6,230 percent from 2017 to 2020.
  • Onit, which offers workflow and AI technology for legal, compliance, sales, IT, HR, and finance departments. It lands at No. 304, with a 408 percent rise in revenue from 2017 to 2020. According to Crunchbase, Onit has reeled in $216.6 million in venture capital.
  • Graylog, a provider of log management software. It sits at No. 309, with revenue growth of 402 percent from 2017 to 2020. Graylog has collected $27.4 million in venture capital, according to Crunchbase. That includes an $18 million round announced this summer.

The North America Technology Fast 500, sponsored by professional services firm Deloitte, is an annual ranking of the fastest-growing tech, media, telecom, life sciences, and energy tech companies in North America.

"The Houston companies on this year's Fast 500 list are transforming the way our city does business by combining technological innovation with entrepreneurial spirit," Amy Chronis, Houston managing partner at Deloitte, says in a news release. "I'm inspired by the ways these organizations have succeeded amid unprecedented times, and I look forward to seeing their progress in 2022."

The top-ranked company is Irvine, California-based medical device company Axonics, whose revenue soared 87,037 percent from 2017 to 2020. The top-ranked Texas company is Austin-based Shipwell, where revenue climbed 32,670 percent from 2017 to 2020. Shipwell provides a shipment-tracking platform. Overall, 5 percent of the Fast 500 companies are based in Texas.

Both Enercross and Onit showed up on last year's Fast 500. Enercross ranked 37th in 2020, with revenue growth of 5,881 percent, and Onit ranked 190th, with revenue growth of 641 percent. Meanwhile, Graylog is a new entrant this year.

Two Houston companies fell off the Fast 500 this year:

  • Lexicon Pharmaceuticals, which ranked 328th last year with revenue growth of 306 percent.
  • Vendor Credentialing Services (symplr), a tech platform that simplifies vendor services, compliance, and more for health professionals. It appeared at No. 426 last year, notching revenue growth of 221 percent.

Not surprisingly, Silicon Valley accounted for one-fifth of the companies in this year's Fast 500, followed by the New York City metro area (12 percent) and New England (8 percent). Nearly three-fourths of the Fast 500 companies specialize in software, and 81 percent of the companies have received venture capital at some point.

"Each year, the Technology Fast 500 shines a light on leading innovators in technology, and this year is no exception," says Paul Silverglate, leader of the U.S. technology sector at Deloitte. "In the face of innumerable challenges resulting from the pandemic, the best and brightest were able to pivot, reinvent and transform and grow."

California-based healthcare co. expands to Houston with new bioskills lab

med skills

Axis Research & Technologies, a California-based healthcare innovation solutions and medical research company, has expanded into the Houston area via a new 10,800-square-foot bioskills lab in Shenandoah last month.

The facility includes a main lab that’s configurable into a single space with over 20 stations, two more lab suites for specialized bioskills training, a conference room for presentations and a large multipurpose area.

Medical professionals can simulate a fully functional operating room in the lab for training and education. It also has the capability of handling cadaver specimens.

The company says the new facility aims to serve surgeons, medical device companies, hospitals and research institutions.

Axis was attracted to Houston thanks to the Texas Medical Center and other world-class medical groups, according to a release from the company. The facility in Shenandoah will be near medical facilities in The Woodlands.

“We are thrilled to expand into the Houston market,” Jill Goodwin, COO of Axis, said in a news release. “This new facility was driven by demand from our clients who have expressed a need for a high-quality bioskills lab in Houston. We repeatedly heard this feedback at the most recent American Academy of Orthopaedic Surgeons (AAOS) conference, which reinforced our decision to bring Axis to the region.”

Axis hosted its first lab event at its Houston-area venue on Feb. 22. The facility is currently accepting bookings for medical trainings, research collaborations and use of its bioskills lab.

“Our goal is to create an environment where groundbreaking medical advancements can take place,” Goodwin added in a news release. “Houston is home to one of the largest medical communities in the country, making it a perfect fit for our expansion.”

Axis' other bioskills labs are located in Nasvhille; Irvine, California; and Columbia, Maryland.

Texas institute grants $12M to bring leading cancer researchers to Houston

cha-ching

Rice University has recruited a prominent Swedish cancer researcher thanks to a $6 million grant from the Cancer Prevention and Research Institute of Texas.

It’s among $68 million in research grants recently awarded by the state agency, and six recruitment grants totaling $16 million to bring leading cancer researchers to Texas.

A news release from the Cancer Prevention and Research Institute of Texas (CPRIT) describes Pernilla Wittung-Stafshede of the Chalmers University of Technology in Gothenburg, Sweden, as “an accomplished and highly gifted biophysical scientist tackling complicated biological questions regarding the role of metals and metal dysregulation in various diseases. She pioneered a new research field around the role of metal ions in the folding and function of metalloproteins.”

Metalloproteins account for nearly half of all proteins in biology, according to the National Institutes of Health. They “catalyze some of the most difficult and yet important functions in [nature], such as photosynthesis and water oxidation,” the federal agency says.

Wittung-Stafshede, a professor of chemical biology and life sciences at Chalmers, is a former professor at Rice.

Aside from the money for Wittung-Stafshede, Houston recruitment grants also went to:

  • University of Texas M.D. Anderson Cancer Center: $2 million to recruit Rosalie Griffin of the Mayo Clinic
  • Baylor College of Medicine: $2 million to recruit Dr. Nipun Verma of the Yale University School of Medicine
  • Baylor College of Medicine: $2 million to recruit Xin “Daniel” Gao of Harvard University and the Massachusetts Institute of Technology

In Houston, cancer research grants were given to:

  • Baylor College of Medicine: $7.8 million
  • M.D. Anderson Cancer Center: $20.7 million
  • Rice University: $ 1 million
  • University of Houston: $1.2 million
  • University of Texas Health Science Center at Houston: $4.5 million

“The awards … represent the depth and diversity of CPRIT funding for cancer research in Texas,” says Kristen Doyle, CEO of CPRIT. “These grants develop new approaches to preventing, diagnosing, treating, and surviving cancer for all Texans.”
