Recently, Seahi Robotics announced the completion of its Series A financing round, raising over RMB 1 billion. This represents the largest single round of financing in the global ocean robotics sector to date.

New strategic and financial investors in this round include Shanghe Momentum Fund (industrial investment arm backing Moore Threads and Iluvatar CoreX / Kunlunxin), Vertex Growth (under Singapore’s Temasek Holdings), China’s largest agricultural industry fund under CITIC Group, Honor Capital, and listed entity Broad-Ocean Motor. Existing shareholders, including GSR Ventures, Vertex Ventures China, Cybernaut / Sparkice Capital, Feldspar Capital, Tsing Capital / Shengjing 360, and Anya Capital, all participated with major over-subscriptions.

Proceeds from this round will be primarily allocated toward core technology R&D, global market expansion, and industrial chain ecosystem construction—accelerating the scaled deployment and reliability enhancement of marine robots in complex underwater environments. Seahi Robotics will continue to focus on technological breakthroughs and industrial execution, closing the engineering feedback loop for deep-sea operational capabilities.

Marine Embodied AI Model "CEORION": Ushering in a New Era of Autonomous Operations

On April 25, 2026, Seahi Robotics officially released "CEORION", the world's first marine embodied AI foundation model.

Unlike traditional underwater robots that rely on manual remote control or pre-programmed routines, CEORION empowers robots with superior perception, understanding, and autonomous execution capabilities in complex ocean environments. Featuring a unified end-to-end architecture, CEORION integrates environmental perception, task comprehension, and motion generation into a single unified model, trained on both real-world operational data and simulation datasets. The company has constructed a marine world model based on millions of hours of commercial operational data, continuously iterating and optimizing through real-world task execution.

Robots powered by CEORION eliminate the need to switch between multiple models for different tasks, covering 12 major underwater operational scenarios, including inspection, non-destructive testing, cleaning, manipulation/grasping, cutting, welding, exploration, search and rescue, and emergency response.

Simulation Benchmark: CEORION achieved over 90% task success rate and over 90% precision manipulation and grasping success rate, matching the skill level of professional human divers.

Zero-Shot Generalization: Facing unfamiliar maritime environments, water quality conditions, lighting changes, or varied robotic platforms, the model demonstrated a zero-shot adaptability exceeding 70%.

The core difficulty in marine scenarios is not merely seeing targets, but comprehending the physical environment. In turbid waters, low-light conditions, and complex ocean currents, robots must integrate multi-source sensory information and possess physical reasoning capabilities. In CEORION's architecture, Seahi Robotics integrated a native physical reasoning module, enabling the model to predict potential risks and optimize decisions prior to motion execution. Internal test data indicates that this capability reduces collision rates by 80%. Even in weak or zero communication environments, robots can autonomously perform task planning and execution.

Six Core In-House Technologies Building a World-Leading Marine Robotics Platform

The ocean represents one of the most challenging application environments for robotics technology. Low light, high turbidity, complex currents, communication constraints, extreme pressure, and severe corrosion place exceptionally high demands on robotic reliability, autonomy, and operational capability.

To address these core challenges, Seahi Robotics has developed a full-stack, in-house technical portfolio spanning six core systems: propulsion, control, sensing, navigation, waterproof sealing, and dynamic deployment & recovery. Each system possesses complete proprietary intellectual property and continuous iteration capabilities, establishing a robust technical framework for commercial marine robotics deployment.

Currently, flagship models such as the "Orca" marine robot possess full-degree-of-freedom operational capabilities spanning full ocean depths from 0 to 10,000 meters. Supporting complex features like autonomous navigation and multi-robot collaboration, Seahi's fleet has achieved stable commercial deployment across full ocean depths in real ocean conditions.

To date, Seahi Robotics has achieved scaled deployment across diverse operational scenarios, including vessel hull cleaning, underwater security, offshore wind maintenance, marine ranching, and subsea pipeline inspection.

Key Industry Milestones (2026)

January 2026: Spearheaded the formulation of China's first regulatory standard, "Operational Code for Underwater Hull Cleaning Robots," in collaboration with the Water Transport Research Institute of the Ministry of Transport.

March 2026: Awarded the First Prize of the Science and Technology Progress Award by the China Institute of Navigation (2025), standing out as the sole private enterprise lead recipient.

April 2026: Selected for the Maritime and Port Authority of Singapore's (MPA) national Underwater Hull Inspection and Cleaning Call for Proposal (CFP), marking the official entry of Chinese tech companies into top-tier global maritime ecosystem design.

For Seahi Robotics, building technical moats stems from long-term dedication. With nearly 20 years of continuous R&D investment—spanning from underlying algorithms to engineering delivery, and from data accumulation to real-world scenario loops—the company has forged a systematic competitive advantage that is difficult to replicate. Following this round, Seahi will deepen investments in its six core systems, marine embodied AI models, and global application scenarios.

Investor Quotes

Wang Lixin (Founding Partner, Shanghe Momentum Fund):

"While the ocean offers immense application space for AI, the physical properties of the deep ocean create an extraordinarily high barrier to entry. Only companies with full-stack software and hardware intelligence capabilities dare to enter. Chen Xiaobo’s team at Seahi Robotics chose to drill where the timber is thickest. They bring a modern spirit of bold innovation to the deep sea, achieving breakthrough after breakthrough with proprietary technology and rapid iteration. Shanghe Momentum is honored to accompany Seahi as it rides the waves forward."
