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.

The company plans to use its funding on product development and differentiation, scaling, and as a bridge to profitability, which Grolnick tells TechCrunch is just around the corner.

“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.

Per the release, the funds will go toward growing the company's platform that allows its users the ability to capture, store, and enable real-time analysis of terabytes of machine data.

"Graylog is well-positioned to be a long-term winner in the rapidly growing market for log management and analysis solutions," says Brian Carney, general partner of Harbert Growth Partners, in the release. "With its focus on delivering a superior analyst experience coupled with a vibrant Open Source community, the company provides customers a compelling alternative to other log management solutions plagued with high complexity and high total cost of ownership (TCO). We are thrilled to partner with the Graylog team to leverage the significant opportunity that lies ahead for the company."

Over the past year, despite the challenging business climate, the company saw growth in business and even expanded its European operations, according to the release.

"As a long-standing customer, Graylog is strategic to our success. We are excited to see new investment that will enable the company to accelerate innovation and continue to deliver excellent log management and SIEM solutions," says Rob Reiner, CTO of PROS, in the release.

Houston researchers develop material to boost AI speed and cut energy use

ai research

A team of researchers at the University of Houston has developed an innovative thin-film material that they believe will make AI devices faster and more energy efficient.

AI data centers consume massive amounts of electricity and use large cooling systems to operate, adding a strain on overall energy consumption.

“AI has made our energy needs explode,” Alamgir Karim, Dow Chair and Welch Foundation Professor at the William A. Brookshire Department of Chemical and Biomolecular Engineering at UH, explained in a news release. “Many AI data centers employ vast cooling systems that consume large amounts of electricity to keep the thousands of servers with integrated circuit chips running optimally at low temperatures to maintain high data processing speed, have shorter response time and extend chip lifetime.”

In a report recently published in ACS Nano, Karim and a team of researchers introduced a specialized two-dimensional thin film dielectric, or electric insulator. The film, which does not store electricity, could be used to replace traditional, heat-generating components in integrated circuit chips, which are essential hardware powering AI.

The thinner film material aims to reduce the significant energy cost and heat produced by the high-performance computing necessary for AI.

Karim and his former doctoral student, Maninderjeet Singh, used Nobel prize-winning organic framework materials to develop the film. Singh, now a postdoctoral researcher at Columbia University, developed the materials during his doctoral training at UH, along with Devin Shaffer, a UH professor of civil engineering, and doctoral student Erin Schroeder.

Their study shows that dielectrics with high permittivity (high-k) store more electrical energy and dissipate more energy as heat than those with low-k materials. Karim focused on low-k materials made from light elements, like carbon, that would allow chips to run cooler and faster.

The team then created new materials with carbon and other light elements, forming covalently bonded sheetlike films with highly porous crystalline structures using a process known as synthetic interfacial polymerization. Then they studied their electronic properties and applications in devices.

According to the report, the film was suitable for high-voltage, high-power devices while maintaining thermal stability at elevated operating temperatures.

“These next-generation materials are expected to boost the performance of AI and conventional electronics devices significantly,” Singh added in the release.

Texas falls to bottom of national list for AI-related job openings

jobs report

For all the hoopla over AI in the American workforce, Texas’ share of AI-related job openings falls short of every state except Pennsylvania and Florida.

A study by Unit4, a provider of cloud-based enterprise resource planning (ERP) software for businesses, puts Texas at No. 49 among the states with the highest share of AI-focused jobs. Just 9.39 percent of Texas job postings examined by Unit4 mentioned AI.

Behind Texas are No. 49 Pennsylvania (9.24 percent of jobs related to AI) and No. 50 Florida (9.04 percent). One spot ahead of Texas, at No. 47, is California (9.56 percent).

Unit4 notes that Texas’ and Florida’s low rankings show “AI hiring concentration isn’t necessarily tied to population size or GDP.”

“For years, California, Texas, and New York dominated tech hiring, but that’s changing fast. High living costs, remote work culture, and the democratization of AI tools mean smaller states can now compete,” Unit4 spokesperson Mark Baars said in a release.

The No. 1 state is Wyoming, where 20.38 percent of job openings were related to AI. The Cowboy State was followed by Vermont at No. 2 (20.34 percent) and Rhode Island at No. 3 (19.74 percent).

“A company in Wyoming can hire an AI engineer from anywhere, and startups in Vermont can build powerful AI systems without being based in Silicon Valley,” Baars added.

The study analyzed LinkedIn job postings across all 50 states to determine which ones were leading in AI employment. Unit4 came up with percentages by dividing the total number of job postings in a state by the total number of AI-related job postings.

Experts suggest that while states like Texas, California and Florida “have a vast number of total job postings, the sheer volume of non-AI jobs dilutes their AI concentration ratio,” according to Unit4. “Moreover, many major tech firms headquartered in California are outsourcing AI roles to smaller, more affordable markets, creating a redistribution of AI employment opportunities.”
