Tiger Technology, a Sofia-based developer of hybrid-cloud data management software, has announced the initial close of a $10m Series A led by TCEE Fund IV, advised by 3TS Capital Partners. TDJ, Endeavor Catalyst and Impetus participated, alongside existing investors MFG Invest and Dimitar Ratchev. The company says the capital will support expansion in the US, Europe and the Middle East, further product development, and a larger sales and partner ecosystem.
Hybrid cloud becomes a control-layer sale
Tiger Technology's flagship Tiger Bridge product sits above customers' existing on-premises and cloud storage. The company says users and applications continue to work through the same file layer while the software moves, protects and exposes data to cloud services or AI workloads. That proposition is aimed at organisations where a wholesale migration would create downtime, retraining or application risk.
The commercial mechanism is therefore less about selling raw storage capacity than about making existing infrastructure usable across more destinations. If Tiger can preserve established workflows while directing inactive data to cheaper tiers and making selected data accessible to cloud tools, customers can modernise incrementally rather than fund a single replacement project. Tiger can then expand through additional capacity, data-protection and AI-access use cases as more of a customer's estate comes under management.
That model also explains the emphasis on partnerships. Tiger says AWS named it a Rising Star Partner for 2025, while its wider ecosystem includes Microsoft Azure and storage and application vendors. Those relationships can place the product inside larger infrastructure projects, but execution depends on keeping deployment predictable across varied legacy systems rather than turning each enterprise rollout into a bespoke integration.
Petabyte-scale references support the expansion case
Tiger Technology reports that its software manages more than 100 petabytes for customers in transportation, media, construction and government. It cites client outcomes including a tenfold increase in file-restore speed during a multi-petabyte migration, storage reductions of up to 90%, and making ten years of historical data available for AI analysis. These are company-reported examples, but they show the operating environments the new investors are underwriting: large data estates where reliability and continuity matter as much as cloud access.
The company reports more than 20 years in the market. The Series A is therefore financing a scale-up of an established product and partner base rather than first product development. The next test is whether international sales and channel expansion can make those large, technically demanding deployments repeatable without weakening the service and integration work that wins trust in mission-critical environments.
