Thalassa

True subsea autonomy

About

Thalassa is building the first truly autonomous, real-time subsea inspection and security solution that enables rapid analysis of all maritime environments through coordinated swarms of AUVs (autonomous underwater vehicles). Our mission is to solve the full breadth of today's subsea challenges and lay the groundwork for tomorrow's maritime technology.

Networks of underwater AI agents

We use cutting-edge AI and hardware tech to navigate unique challenges of maritime environments.

  • Swarming

    Task Coordination

    Our AUVs operate as an interconnected fleet to coordinate all types of subsea missions. We enable complex missions that are impossible with a single AUV and speed up critical inspections over vast stretches of subsea infrastructure. Swarming eliminates point failure risk for more resilient missions.

  • Real-time

    Dynamic Missions

    We enable live feedback between the operator and swarm of AUVs in all subsea environments. Infrastructure anomalies can be instantly communicated to surface operators to minimize costly downtime and hazard risk. Constant feedback enables dynamic mission adaptation at all times.

  • Intelligence

    Onboard AI

    Our intelligent fleet of underwater agents enables true autonomy through edge processing. AI-enabled sensor fusion sharpens navigation and creates a holistic view of mission data prior to recovery. Onboard processing minimizes required bandwidth in deep subsea environments.

What we are working on

We are building technology to empower safer energy, build resilient and secure infrastructure, and support marine vitality.

  • Power Beneath the Waves

    Energy

    We support a cleaner, safer energy future by enabling efficient offshore wind development, detecting leaks in oil and gas infrastructure, and making underwater operations more sustainable, intelligent, and low-risk for both people and the planet.

  • Monitoring for Restoration

    Marine Vitality

    We support healthier oceans and waterways, from monitoring aquatic habitats to mapping changes in sediment, flow, and biodiversity. By partnering with conservation groups, we help restore ecosystems, protect wildlife, and bring data-driven insight to support global marine vitality.

  • Protecting Underwater Infrastructure

    Secure Infrastructure

    We enhance the resilience and security of critical underwater infrastructure. From inspecting undersea telecom cables for damage or sabotage to monitoring structural integrity at ports, our autonomous systems help protect the invisible foundations of global connectivity and trade, before problems escalate.
