An Autonomous Fleet for the Deep

Seventy percent of offshore infrastructure failures originate underwater, yet inspecting what's beneath the surface still requires chartering ships at over $50,000 per day and deploying human crews into harsh conditions. Bubble Robotics is building a fundamentally different approach — persistent, AI-driven robotic systems that stay at sea for months, operating entirely from shore at roughly one-tenth the cost.

The $5M pre-seed round was co-led by Episode 1 Ventures, Asterion Ventures, and Norrsken Evolve. Born out of Entrepreneurs First and founded by ex-NASA JPL engineer Patricia Apostol and CEO Jean Crosetti, the company is tackling a market that has barely been touched by automation.

How It Works

The platform revolves around two core components. BubbleDock is an energy-autonomous surface station that launches from shore and remains resident at sea for up to six months with onboard power generation. From the dock, BubbleBots — subsea autonomous vehicles equipped with cameras, sonar, multibeam echo sounders, side-scan sonar, hydrophones, and environmental sensors — deploy on demand to inspect, survey, and monitor whatever lies below.

The entire operation runs as Robotics-as-a-Service: zero capital expenditure for customers, who subscribe to outcomes like inspection reports and AI-powered insights rather than purchasing hardware. Bubble owns and operates the fleet.

Why It Matters

Traditional offshore inspection is constrained by weather windows, vessel availability, and crew logistics. Companies typically get one annual two-week survey window. Bubble's persistent presence means weekly or on-demand surveys become possible, catching problems before they become failures. Their target markets span ports and coastal infrastructure, offshore energy, environmental monitoring, and maritime security — backed by technology partners including NVIDIA, ETH Zurich, and France's Ifremer research institute.
