Business
Thalassa Holdings Ltd (THAL.L) is a British Virgin Islands-based holding company engaged in international businesses across rental income and product development segments. The company generates rental income from investment properties leased under operating leases and develops innovative products, including control software for flying node bespoke seismic sensor systems; it also pursues research and development of autonomous underwater vehicles through Autonomous Robotics Ltd, geophysical project management, services and equipment supply, as well as cashless payments, fan engagement, access control and data insights for events and venues. Its subsidiaries encompass DOA Alpha Ltd, DOA Exploration Ltd, DOA Delta Ltd, Apeiron Holdings (BVI) Ltd, WGP Geosolutions Limited, Alfalfa Holdings AG and Thalassa Holdings (II) Ltd; the group targets sectors such as oil and gas equipment, marine robotics and IoT-related technologies with operations centered internationally from its headquarters in Road Town, British Virgin Islands, where it was incorporated in 2007. In recent developments, Thalassa, as a holder of approximately 40% of Anemoi International Ltd shares, expressed enthusiasm for Anemoi's proposed acquisition of Trasna Solutions Technologies Limited in October 2025, a move anticipated to enhance growth through Trasna's semiconductor, mobile IoT, edge computing, AI and blockchain solutions for end-to-end IoT lifecycle management. The company increased its stake in Surgical Innovations Group plc to 10.80% via acquisition of 8 million shares in August 2024 and completed an equity placing of 8.71 million shares in December 2024 following publication of a prospectus. These strategic investments and capital raises reflect Thalassa's focus on expanding its portfolio in medtech and IoT-adjacent technologies amid ongoing product development activities.
