What Vaarst does
Vaarst was a Bristol, UK-based company that developed underwater AI technology for subsea robotics applications in the offshore energy sector. Its core product was an autonomous subsea systems platform combining computer vision, anomaly detection, and multimodal data processing (video, image, sensor streams) to enable AI-powered inspection and monitoring of offshore wind farms, oil and gas infrastructure, and other subsea assets. The company's stated value proposition centered on reducing the cost and risk of underwater inspection through autonomous operation rather than crewed or remotely-piloted alternatives. Its customer base targeted the offshore energy sector, including offshore wind farm operators and oil and gas companies, though specific end-customer logos were not disclosed.
Vaarst's business model was based on deploying and operating AI-powered subsea robotics and autonomous underwater vehicles, likely through project-based or contract service arrangements (though no pricing or revenue model details were publicly disclosed). The company employed 51-100 people and raised £15.2 million in April 2022 from a consortium including Legal & General Capital, Equinor Ventures, Foresight Group, Future Planet Capital, and IQT to fund continued development of its underwater AI platform. Its operating geographies spanned the UK, Irish Sea, broader Europe, Japan, and the United States.
In September 2024, Vaarst merged with Rovco to form Beam, a combined subsea robotics and engineering firm headquartered in Bristol and Aberdeen. The merged entity operated for approximately eight months before filing for administration in May 2025 following an unsuccessful fundraising effort. Selected assets and talent were subsequently acquired by Rosenxt UK Ltd. in July 2025. A separate entity named Vaaris appeared in a January 2026 transaction involving TotalEnergies' Nigerian offshore oil assets, though the relationship to the original Vaarst business is unconfirmed.
