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.

TMC launches new biotech partnership with Republic of Korea

international collaboration

Houston's Texas Medical Center has launched its new TMC Republic of Korea BioBridge.

The new partnership brings together the TMC with the Osong Medical Innovation Foundation, or KBIOHealth. The Biobridge aims to support the commercialization of Korean biotech and life science startups in the U.S., foster clinical research, and boost collaboration in the public, private and academic sectors.

Through the partnership, TMC will also develop a Global Innovators Launch Pad to foster U.S. market entry for international health care companies. Founders will be selected to participate in the 10-week program at the TMC Innovation Factory in Houston.

“Gene and cell therapies are driving biotech innovation, opening possibilities for treating diseases once thought untreatable," William McKeon, president and CEO of the Texas Medical Center, said in a news release. "Expanding biomanufacturing capacity is essential to delivering the next wave of these therapies, and partnerships with leading innovators will strengthen our efforts in Houston and internationally.”

McKeon officially signed the TMC Korea BioBridge Memorandum of Understanding with Myoung Su Lee, chairman of KBIOHealth, in South Korea in October.

"This collaboration marks a significant milestone for Korea’s biohealth ecosystem, creating a powerful bridge between Osong and Houston," Lee added in the release. "By combining KBIOHealth’s strength in research infrastructure and Korea’s biotech talent with TMC’s global network and accelerator platform, we aim to accelerate innovation and bring transformative solutions to patients worldwide.”

This is the seventh international strategic partnership for the TMC. It launched its first BioBridge with the Health Informatics Society of Australia in 2016. It launched its TMC Japan BioBridge, focused on advancing cancer treatments, last year. It also has BioBridge partnerships with the Netherlands, Ireland, Denmark and the United Kingdom.
