Bulgarian enterprise infrastructure startup Tiger Technology has secured a €8.8 million ($10 million) Series A funding round to accelerate its international expansion and further develop its hybrid cloud data management platform for enterprise customers.

The round was led by TCEE Fund IV, advised by 3TS Capital Partners, with participation from TDJ, Endeavor Catalyst, Impetus, and existing investors including MFG Invest and Dimitar Ratchev.

The fresh capital will support the company's expansion across the US, Europe, and the Middle East, while funding further product development and the growth of its sales and partner ecosystem.

"This investment is an important validation of the technology, customer trust and international business our team has built," said Iravan Hira, CEO of Tiger Technology. "It gives us the resources to accelerate our global expansion, amplify our partnerships with leading cloud and technology platforms, and bring Tiger Technology's always-on, AI-ready data infrastructure to many more companies operating in mission-critical environments."

Building hybrid infrastructure for AI

Founded in Bulgaria, Tiger Technology develops software that helps enterprises manage data across on-premises, cloud, and edge environments without disrupting existing operations. Its flagship platform, Tiger Bridge, enables organizations to seamlessly access and move data between storage environments while preserving existing infrastructure.

The company says its technology addresses a growing challenge for enterprises adopting AI. According to Tiger Technology, more than 40% of enterprise data remains stored on-premises, around 80% is unstructured, and more than half is considered "dark data" that is never analyzed or used. As organizations increasingly deploy AI systems that rely on accessible, high-quality data, hybrid data infrastructure has become a strategic priority.

The startup estimates the global hybrid storage market will reach $29.3 billion by 2030, driven by enterprise AI adoption, growing volumes of unstructured data, and increasing requirements around security and data sovereignty.

Strategic partnerships and global expansion

As part of its growth strategy, Tiger Technology plans to deepen partnerships with major hyperscale cloud providers. Earlier this year, Amazon Web Services (AWS) named the company a Rising Star Partner of 2025, recognizing its work in helping enterprises migrate and manage large-scale file infrastructures in hybrid cloud environments.

"Many years ago, we made a bet that felt contrarian at the time," said Alexander Lefterov, Founder and CTO of Tiger Technology. "The industry was drawing a hard line between cloud and on-premises, but we believed enterprises would need a transparent bridge between the two. Adoption of AI, always-on data access and an increasing threat landscape are significant drivers for our solutions and our growth."

Today, the company says it manages more than 100 petabytes of enterprise data across sectors including transportation, media, construction, and government. Recent customer deployments have delivered up to a 10x improvement in file restore speeds during multi-petabyte cloud migrations, reduced on-premises storage requirements by up to 90%, and enabled organizations to unlock years of historical data for AI analysis.

Investors back enterprise AI infrastructure opportunity

For investors, the company's positioning at the intersection of hybrid cloud infrastructure and enterprise AI was a key factor behind the investment.

"Tiger Technology stood out through a combination of unique technical breakthroughs in petabyte-level hybrid storage, mission-critical customer deployments, and a clear market opportunity driven by AI adoption, data security and sovereignty," said Sever Totia, Partner at 3TS Capital Partners.

Momchil Vassilev, Managing Director of Endeavor Bulgaria, added that the company represents the type of globally ambitious deep tech business the organization aims to support, combining Bulgarian engineering talent with international growth ambitions.
