Leviathan · Observe the Seas

Coastal Intelligence for Marine Conservation. Ocean observatories, and the system that makes sense of them.

01 · Signal. We share the ocean.

The ocean is full of signals, and most of them disappear as quickly as they happen. Marine life monitoring still depends largely on fragmented observations. Leviathan begins at the moment before anyone is watching.

02 · Observation. Leviathan is already watching.

An ocean observatory deployed at MBARI in Moss Landing, operating autonomously in one of the harshest environments there is. Visual and thermal sensing, streaming back to a centralized intelligence platform, turning deliberately toward what it finds.

03 · Evidence. A detection is a claim.

LeviathanOS turns fragmented acoustic, visual and vessel tracks into one structured, auditable event chain. An honest uncertainty bound, and a review state that is recorded rather than hidden.

04 · Memory. The ocean has a memory.

Historical sightings, camera geometry, vessel context and human review. LeviathanOS joins one observation to everything already known about that place, and about that animal.

05 · Intelligence. Ask the ocean a question.

The market is not missing another isolated sensor. It is missing the layer that synthesizes multi-source data into operational decisions. LeviathanOS keeps a path back to the evidence behind every answer.

06 · Network. Observe the seas.

Coastal Intelligence for Marine Conservation. Leviathan starts with whales because they are the highest-signal, highest-urgency coastal intelligence use case.

What Leviathan is

A vessel can follow every rule and still never see the whale in time.

Software · in operation

LeviathanOS

Detection, context, human review and report-ready evidence in one auditable event chain.

Hardware · deployed at MBARI

Ocean Observatories

A bispectral AXIS Q8752-E is deployed at the Monterey Bay Aquarium Research Institute in Moss Landing, over the canyon head, with co-aligned visual and thermal imaging built for fog, glare and darkness.

Leviathan Live · read-only

The observatory is real. You can look through it.

A live shore view from Moss Landing, kept read-only. Detection boxes are model-generated candidates rather than confirmed whales, and the view is not up every hour. When it is down, we say so.

One observatory sees a stretch of coast. A network begins to understand it.

Team

Built by people who go to the water.

A small group across software, ocean hardware, marine science and story. Every one of them has been on the coast for this.

  • Nate Krajewski

    Founder & Engineer

    Founder and engineer. Built LeviathanOS end to end, from the detection and evidence layer through the agent and reporting tools, and led the commissioning of the first shore-based observatory at MBARI. Works at the join between marine science and production software, where a claim has to survive both a researcher and a operator.

  • David Pearson

    Systems Engineer

    Systems engineer with a background in subsea robotics and field instrumentation. Responsible for sensor integration, power and connectivity, and the mechanical and environmental design that keeps an observatory running through salt, fog and winter storms on an exposed coastline.

  • Bridget Paskil

    Scientific Advisor

    Scientific advisor. Brings marine science and institutional research experience to Leviathan's validation pathway, shaping how detections are compared against acoustic and photo-identification records. Keeps every published claim tied to evidence a reviewer could check.

  • Spenser Rapier

    Prototype Engineer

    Prototype engineer. Leads mechanical design, CAD and fabrication for observatory hardware, turning field requirements into mounts, enclosures and assemblies that can be installed by a small team and serviced on a working pier.

  • James Rice

    Brand & Narrative

    Founder and CEO of Fiction Tribe, a creative studio building brands and narrative for technology companies. Advises Leviathan on positioning, story and how a company making scientific claims should sound in public. An early investor in the company.

  • Adam Schlenger

    Advisor

    Advisor through Braid Theory, the blue-technology accelerator. Brings marine energy and sensor-science perspective, and connects Leviathan into the ocean-innovation network across research institutions, ports and industry partners.
