TIN Capital Leads €10 Million Series A Funding Round in Belgian Cloud-Native Scaleup StackGuardian

Dutch cybersecurity investor and HSD partner 'TIN Capital' has announced it has led the Series A funding round for Belgium-based StackGuardian, a European cloud-native scaleup that enables organisations to deliver secure and compliant self-service infrastructure faster and more intelligently. This latest round brings StackGuardian’s total funding to €10 million, including its earlier seed round.

Earlier, Belgian investors Volta Ventures and InvestLink backed the Mechelen-based software company, and both have also participated in this round. For TIN Capital, this marks the fourth investment from its European Cyber Tech Fund V. The firm aims to make two more investments from the fund this year, which is scheduled to close on 31 October with an expected size of over €80 million.

 

Karl Driesen, Co-Founder & CEO of StackGuardian - “Organisations are under increasing pressure to enable self-service infrastructure while also meeting the highest standards of security, compliance and cost efficiency. This funding enables us to scale our go-to-market strategy, support our growing global customer base, and accelerate innovation – particularly in AI – so teams can orchestrate infrastructure faster, smarter and more securely.”

Bart Houlleberghs, Partner at TIN Capital - “We see a clear opportunity in how large organisations manage cloud infrastructure at scale. As cloud environments grow, success is not just about speed or convenience – it’s about getting it right and secure the first time. StackGuardian builds security and compliance directly into the deployment process, reducing alerts, easing pressure on infrastructure teams, and giving CFOs greater control over cloud spending.”

“With visible traction among customers such as Siemens, RheinEnergie and Bpost, we believe this is the right moment to support StackGuardian’s growth,” added Michael Lucassen, Partner at TIN Capital.
