Diving into Uncharted Waters: HydroSight Raises US$5M to Map the Seabed with AI

HydroSight has raised a US$5 million seed round to turn scattered marine survey data into a continuously updated, intelligent picture of the ocean floor — with Vertex Ventures Israel among its backers.

The problem beneath the surface

Sonar systems and marine survey technologies collect ever-larger volumes of data about the seabed. Yet turning that raw information into a clear, current picture still depends heavily on slow, manual processes that require specialised expertise. As energy projects, communications cables, ports and other marine infrastructure continue to expand offshore, and available land and coastal space grows more constrained, the ability to accurately read and understand the seabed is becoming a strategic necessity rather than a niche technical challenge.

HydroSight's approach

Founded in late 2025 by CEO Tomer Adler, CTO Haitham Ezzy and COO Chen Megera, HydroSight was built around a gap the three founders encountered directly in their own maritime work. The company's platform integrates marine survey data from different sources and time periods, automatically identifying changes, anomalies and patterns to produce a detailed, continuously updated map of the seabed. The result is an intelligence layer that can be built into infrastructure planning, operations and management, cutting down processes that previously required many hours of manual review.

HydroSight already runs projects with marine infrastructure owners in Israel and internationally, operating on a B2B enterprise model that serves ports, energy companies, telecom cable operators and other marine infrastructure providers.

“Beneath the surface of the sea lies a vast world we still know very little about, even though a significant part of our lives already depends on it,” said Adler. “We founded HydroSight to help the world better understand what's happening beneath the sea's surface, and to enable more precise, intelligent and sustainable development of the underwater environment.”

A widening offshore economy

The stakes extend well beyond any single company's balance sheet. Roughly 30% of the world's oil and gas is produced at sea, and more than 99% of international data traffic runs through cables laid on the seabed. As the shift to clean energy accelerates, coastlines grow more crowded, and demand for new marine infrastructure rises, the underwater environment is set to carry an even greater share of global economic activity — while remaining one of the least understood parts of the planet.

Vertex's perspective

Vertex Ventures Israel backed HydroSight for its ability to turn a historically opaque environment into something planners and operators can act on with confidence. As offshore infrastructure becomes more critical to global energy and connectivity, tools that make the seabed legible in near real time stand to become foundational rather than optional — and HydroSight's early traction with marine infrastructure owners in Israel and abroad points to a platform built for that shift.

Looking ahead

With fresh capital in hand, HydroSight plans to expand its team, deepen its AI and analytics capabilities, accelerate commercial activity, and grow its footprint with customers in international markets. As offshore infrastructure becomes more central to energy, connectivity and coastal development, HydroSight's bet is that the companies best equipped to build and operate it will be the ones that can finally see the seabed clearly.
