Boundary Holding, the Luxembourg-based deep-tech venture capital firm founded by Rajat Khare, has completed its exit from Defendec, an Estonia-based company developing AI-powered autonomous surveillance technologies. Boundary Holding initially invested in Defendec in 2021 and is reported to have generated a significant return from the investment.
The exit follows Defendec’s acquisition by Canadian surveillance technology company Vosker Corp, which acquired the Estonian company as part of its broader efforts to expand its technology and international capabilities.
A Successful Exit Reinforces a Regional Investment Strategy
For Boundary Holding, the Defendec exit represents both the conclusion of a five-year investment and an opportunity to redirect capital toward emerging AI and deep-tech companies.
More broadly, the investment has reinforced the firm's interest in Eastern Europe, particularly Estonia, as a region capable of producing globally relevant technology companies.
“Our association with Defendec is a reflection of what we have held as a belief for quite some time now,” Khare said. “That Eastern Europe is the next big chapter in tech innovation. Estonia, as well as other parts of the region, have been building powerful capabilities in AI and deep-tech.”
Khare has highlighted the region’s engineering talent and comparatively lower operating costs as factors that can help startups develop sophisticated technologies while remaining capital efficient.
“The most impressive aspect has been that it's not only the engineering prowess of the region's talent, but the ability of the founders to create globally-relevant technologies while keeping the cost down,” he added.
According to Khare, the Defendec transaction has further reinforced Boundary Holding’s interest in the region and its potential as a source of technology-driven companies with international ambitions.
Estonia’s Growing Deep-Tech Ecosystem
The Defendec transaction comes against the backdrop of Estonia’s expanding technology ecosystem. While the country has long been associated with digital services and startups, its technology sector has increasingly extended into areas such as artificial intelligence, robotics, defense technology, energy, and industrial systems.
Estonia has also emerged as an important contributor to deep-tech activity across the Baltic region. Companies originating from the country include Starship Technologies, known for autonomous delivery robots; Veriff, which develops AI-driven identity verification technology; Stargate Hydrogen, focused on green hydrogen technologies; Gridio, which develops intelligent energy-management solutions; and Frankenburg Technologies, a defense technology company.
Other notable companies contributing to the wider Baltic technology landscape include Latvia-based Aerones, which develops robotic systems for wind turbine maintenance, and Lithuania-based CAST AI, which focuses on cloud infrastructure optimization.
Together, these companies illustrate the breadth of technology development taking place across the region, spanning software, artificial intelligence, robotics, energy, and defense applications.
Khare’s Focus on Emerging Technology Markets
Khare’s interest in identifying emerging technology opportunities predates the establishment of Boundary Holding. Earlier in his career, he founded Prophecis, a data analytics and market intelligence company.
That experience has contributed to Boundary Holding’s investment strategy, which focuses on identifying companies developing technologies with potential applications across global markets.
The firm’s investment in Defendec reflects this approach, with Estonia representing a market where advanced engineering capabilities and a growing startup ecosystem intersect with relatively efficient development costs.
Deep Tech Beyond the Hype
The Defendec exit also highlights a broader shift in how deep-tech opportunities are being evaluated. Rather than focusing exclusively on consumer applications or software platforms, many emerging companies in Eastern Europe are working on complex engineering challenges across areas such as AI, surveillance, energy, robotics, industrial automation, and defense.
In this environment, artificial intelligence increasingly serves as a technological layer within larger systems rather than as a standalone product category.
For investors, this creates opportunities to identify companies developing specialized technologies for global markets while operating from regions with strong technical talent and comparatively lower development costs.
Boundary Holding’s continued interest in Eastern Europe suggests that the firm views the region as an increasingly important source of deep-tech innovation. The Defendec exit provides a completed example of that investment strategy while freeing capital for the firm to pursue its next generation of technology-focused opportunities.
