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.

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.
