Company profile
researched Aug 2026DeepSea Technologies is an Athens-based maritime technology company that applies artificial intelligence to vessel performance monitoring and optimisation. Its systems capture high-frequency sailing data from ships and use vessel-modelling techniques to produce predictive, real-time intelligence for fuel consumption, emissions, speed and voyage execution across fleets. The company positions its products as decision-support and automation layers that work in live operating conditions and aim to close the gap between optimisation plans and what is actually executed on board.
The platform comprises four integrated products introduced over time: Neuro for onboard data capture and Cassandra for AI-powered vessel analytics (both launched in 2021), followed in 2023 by Pythia for voyage optimisation and HyperPilot for autonomous speed control. Stated outcomes targeted by the products include reduced fuel consumption, lower CO2 emissions, improved Carbon Intensity Indicator (CII) performance, EU ETS optimisation, reduced crew workload and stronger TCE outcomes. The company reports more than 700 years of accumulated sailing data underpinning its models.
The organisation combines data scientists, AI researchers, software engineers, marine experts, captains and product specialists, and reports a team of over 95 people, more than 70 of whom are engineers and specialists.
Founding story
DeepSea Technologies was founded in 2017 in Athens by Dr. Konstantinos Kyriakopoulos, an AI researcher at the University of Cambridge, and Roberto Coustas, an Oxford-educated mechanical engineer and vessel performance manager, pairing artificial intelligence expertise with operational experience in shipping. Kyriakopoulos initially served as CTO alongside Coustas as CEO, and is listed as CEO and co-founder in later company materials.
Business model
DeepSea supplies AI-based vessel performance software and onboard data-capture technology to shipping companies operating commercial fleets. Following the 2021 investment, distribution is also pursued through Nabtesco's sales network alongside joint product development.
Traction
The company reports over 700 years of sailing data, four integrated products and 95+ staff. External validation includes a ClassNK endorsement for Cassandra in 2022 and DNV Type Approval for HyperPilot in 2024. Investor due diligence ahead of the 2021 round included technical testing of the accuracy of the company's AI models.
Latest developments
HyperPilot, the autonomous speed control system, received DNV Type Approval in 2024. The company reports a team of 95+ and four integrated products, and is recruiting for sales and engineering roles.

Market position
Described as a maritime technology specialist in vessel performance monitoring and optimisation that has grown from an AI startup into an established technology provider in maritime optimisation; investors conducted competitive analysis against other technology companies in the sector prior to the 2021 round. Since 2023 it operates within the Nabtesco Group, whose parent is described as a Japanese leader in shipping automation with roughly 40% market share.
Technology
The company builds vessel-modelling and AI systems trained on high-frequency sailing data collected onboard. Capabilities span onboard data capture (Neuro), AI-powered vessel analytics including all-weather fuel consumption prediction and CII tracking (Cassandra), voyage optimisation (Pythia) and autonomous speed control (HyperPilot). The company has stated its models can predict vessel behaviour with a view to delivering cost and CO2 emissions reductions of over 10%.
Go-to-market
Direct enterprise sales to shipping companies through business development teams covering regions including APAC and the Nordics, supplemented by access to Nabtesco's sales network and joint product development following the 2021 investment and subsequent group ownership. Independent validation from classification societies (ClassNK endorsement for Cassandra, DNV Type Approval for HyperPilot) is used to support credibility with fleet operators.
Commercial shipowners, ship operators and charterers managing global fleets subject to fuel cost pressure and emissions regulation such as IMO vessel efficiency rules, CII and the EU ETS.
Geography
Headquartered in Athens, Greece, with a remote-first working model and open roles based in Athens and remotely. Commercial expansion following the 2021 funding round was focused on Asian markets, supported by Nabtesco's regional sales network, and business development roles cover APAC and the Nordics.
History
Founded in Athens in 2017 to bring AI to the maritime industry, DeepSea built its high-frequency sailing data foundation and core vessel-modelling engine between 2018 and 2020 while contributing research to conferences and AI initiatives. Neuro and Cassandra launched in 2021, the same year the company raised €5 million led by Nabtesco Technology Ventures. Cassandra received a ClassNK endorsement in 2022. In 2023 the platform expanded with Pythia and HyperPilot, and Nabtesco became the primary shareholder, making DeepSea part of the Nabtesco Group. HyperPilot received DNV Type Approval in 2024.

In 2023 Nabtesco became DeepSea's primary shareholder and DeepSea became part of the Nabtesco Group, combining DeepSea's AI capabilities with Nabtesco's marine control systems and industrial automation expertise. Trade press reported the transaction as an acquisition in July 2023.
DeepSea expanded its platform into voyage optimisation (Pythia) and autonomous speed control (HyperPilot).
Cassandra received a ClassNK endorsement covering all-weather fuel consumption prediction and CII tracking.
DeepSea Technologies raised €5 million from existing and new investors to fund technology and product research, design and development, and to accelerate international commercial expansion with a focus on Asian markets. The round was led by Nabtesco Technology Ventures, the corporate venture capital arm of Nabtesco Corporation (operated by Emerald Technology Ventures), with participation from The Signal Group and existing investor ETF Partners. The investment followed a technical due diligence process covering the accuracy of the company's AI models and competitive analysis.
Alongside the 2021 investment, DeepSea Technologies and Nabtesco began a commercial and research cooperation covering distribution through Nabtesco's sales network, development of joint products and joint research. Further collaboration opportunities were also to be explored with The Signal Group.
DeepSea launched Neuro, its onboard data capture product, and Cassandra, its AI-powered vessel analytics product.
