A company built to save lives

Thytadel was founded by a father and son who understood risk firsthand - on the water, under pressure, where seconds decide outcomes.

Origins

Where the story
begins

Thytadel’s origin lies in a lifelong relationship with the sea.
Sergey Dzhienbaev competed at the highest levels of professional sailing in some of the world’s most demanding classes - including Tornado, 49er, and Nacra 17. These were not controlled environments. They were defined by speed, instability, and consequence.

Beyond competition, Sergey became deeply involved in offshore operations, holding world records and serving as manager and keeper of Comanche - one of the most advanced racing yachts ever built - from the Maxi Yacht Rolex Cup in 2015 through to the RORC Transatlantic Race in 2022.

The Challenge

The Problem That United Them

A new generation of systems thinking

Growing up around elite sailing campaigns, operations rooms, and engineering discussions, Alexander Dzhienbaev developed an early understanding of risk, complexity, and consequence. Alexander pursued engineering and business at University College London, while simultaneously engaging with early-stage technology - from mobile application startups to emerging AI systems. Where Sergey understood the physical reality of risk, Alexander focused on how systems, software, and intelligence could reduce it.
Their perspectives were different.
Their goal was the same.

When seconds matter

Across decades of sailing, one reality remained constant: when someone falls into water, response time determines survival. Human attention alone was not enough. Visibility is limited. Noise is constant. Distractions are unavoidable. Together, father and son decided to address the problem not as a product opportunity, but as a responsibility.
They designed a system capable of detecting incidents, assessing severity, and prompting immediate response - technology shaped by real conditions, not theory.

That system became UK Patent GB2623311.

From family system to institutional platform

The patented technology led to early licensing agreements and live deployments in competitive sailing environments. As the system matured, its relevance extended far beyond water.
The same conditions that define offshore sailing - incomplete information, delayed recognition, fragmented response - exist across public spaces, infrastructure, and asset-heavy environments. Thytadel was formed to carry that original system forward - expanding it into a broader safety intelligence platform, while applying the same operational discipline to government supply, private execution, and asset operations.
The company grew.
The principle did not change.

Guided by those who competed at the highest level

From the beginning, the venture benefited from guidance and support from Olympic-level sailors who understood both competition and consequence. This included Mitch Booth, Rodion Luka, and Fernando Echávarri - rivals and friends of Sergey, and later mentors to Alexander. Their insight ensured the technology was not only innovative, but realistic - shaped by the expectations of those who had operated at the edge of human and technical limits.
