DAIVIN! and the Future of Tankless Underwater Breathing

DAIVIN! is a deep-tech startup rethinking one of humanity’s oldest engineering assumptions: that breathing in extreme environments requires heavy, pressurized tanks filled with stored gas. Founded in 2025 and currently active in San Francisco, the company is building tankless dive gear designed to unlock what it calls breath autonomy—the ability to generate breathable oxygen on demand from the environment itself.

At its core, DAIVIN! challenges a century of underwater diving convention. Traditional scuba systems rely on bulky oxygen tanks that dictate where divers can go, how long they can stay, and how much risk they must accept. DAIVIN!’s alternative is radical yet rooted in physics: instead of carrying oxygen, divers carry energy and use water—the medium they are already immersed in—as the oxygen source.

The implications extend far beyond recreational diving. From military and rescue operations to space exploration and high-altitude missions, DAIVIN! positions oxygen not as a logistics problem but as an energy problem. In doing so, the company opens a new frontier in how humans survive and operate in extreme environments.

Who Is Behind DAIVIN! and What Experience Shapes Its Vision?

DAIVIN! was founded by Leo Kankkunen, an electrical engineer, certified diver, and two-time founder with a rare blend of military, academic, and industrial experience. Kankkunen became the youngest person in Finland to achieve the country’s highest national electrical certification, granting him the authority to independently execute and sign off on complex high-voltage power line constructions.

He holds a Bachelor of Engineering in Electrical Engineering and a Master of Science in Industrial Engineering and Management with a focus on innovation. His professional background spans seven years in the electrical industry, combined with military service and hands-on experience as a certified diver. This intersection of disciplines—electrical systems, safety-critical infrastructure, and extreme-environment operations—directly informs DAIVIN!’s technical and philosophical approach.

The company’s primary partner is Tyler Bosmeny, whose involvement supports DAIVIN!’s trajectory as a high-ambition deep-tech venture. With a team size of one at its current stage, DAIVIN! exemplifies the founder-driven innovation model, where breakthrough hardware development begins with focused, first-principles engineering.

Why Has Underwater Breathing Technology Barely Changed in 100 Years?

Despite dramatic advances in aviation, computing, and materials science, underwater breathing systems remain fundamentally similar to those used nearly a century ago. Modern scuba gear still relies on pressurized gas tanks, regulators, and complex logistics chains that limit flexibility and safety.

This stagnation creates several compounding problems. Oxygen tanks hard-limit dive duration and location, making logistics—not human skill or physical possibility—the primary constraint. In elite, military, or remote operations, the effort required to transport and manage tanks often outweighs the mission itself.

Safety is another major concern. Pressurized gas systems introduce mass, failure modes, and cognitive load, contributing to a risk profile that makes diving roughly one thousand times more dangerous than flying. Additionally, bulky equipment increases drag, forcing divers to move significantly slower than on land and extending exposure time in hazardous environments.

Cost further entrenches the problem. Professional diving systems can cost tens of thousands of dollars, with specialized gases like helium exceeding one hundred dollars per tank. Together, these factors explain why innovation stalled: the system works “well enough,” but only at great expense and risk.

What Core Problem Is DAIVIN! Actually Solving?

DAIVIN! identifies the true bottleneck in underwater and extreme-environment operations as oxygen logistics. The challenge is not the absence of oxygen in water or air, but the inefficiency and danger of storing and transporting it in pressurized containers.

Traditional systems treat oxygen as a consumable resource that must be carried from point A to point B. This framing creates dependencies on supply chains, support teams, and pre-planned infrastructure. In environments where logistics break down—deep underwater, disaster zones, remote mountains, or space—this approach becomes a liability.

DAIVIN! reframes the problem by asking a simpler question: if oxygen is already present in abundance, why carry it at all? A single bottle of water contains enough oxygen to sustain a human for an entire day. The limitation has never been availability, but extraction.

How Does DAIVIN!’s Tankless Dive System Actually Work?

DAIVIN!’s solution uses electrolysis to extract oxygen directly from water and convert it into breathable gas in real time. By applying direct current to water molecules (H₂O), the system splits them into oxygen (O₂) and hydrogen (H₂). The oxygen is delivered to the diver on demand, while hydrogen is safely managed within the system.

The hardware is designed as a lightweight vest worn by the diver, containing triple-redundant electrolyzers. Power is supplied by a compact battery belt that replaces the traditional weight belt used in diving. At the circuitry level, the system is quadruple-redundant, meaning multiple independent electrical paths ensure continuous gas generation even in the event of component failure.

Because oxygen is generated only when needed, the system eliminates the risks associated with stored pressurized gas. Dive duration becomes primarily a function of battery life rather than tank capacity, enabling a fundamentally different operational model.

Why Is Electrolysis a Breakthrough for Deep and Safe Diving?

Electrolysis offers several advantages that extend beyond convenience. By eliminating stored gas, DAIVIN!’s system reduces mass, complexity, and cognitive load for the diver. The result is improved mobility, shorter task times, and lower exposure to environmental hazards.

At depth, the benefits compound. The system enables dives to depths of up to 200 meters without nitrogen narcosis, oxygen toxicity, or reliance on expensive helium mixes. Because hydrogen exits body tissues faster than nitrogen, decompression times are reduced when decompression is required.

Safety scenarios are also redefined. If a diver becomes entangled, a single palm-sized battery can provide up to an hour of additional breathing time. In remote operations without support teams, the ability to recharge batteries using solar power eliminates dependence on pre-positioned supplies.

How Does Tankless Breathing Change Mobility and Mission Design?

Removing bulky tanks dramatically reduces drag and restores underwater mobility closer to natural human movement. Divers can move faster, maneuver more precisely, and operate with greater situational awareness. This shift has direct implications for military, scientific, and rescue missions where time and agility are critical.

Missions can begin almost anywhere. With a shoebox-sized system and access to water, divers are no longer constrained by tank availability or refilling infrastructure. Planning shifts from logistics coordination to energy management, simplifying operations and reducing costs.

This flexibility also opens new use cases that were previously impractical or too dangerous. Extended inspections, deep-sea research, and rapid-response rescue operations become more feasible when oxygen supply is no longer the limiting factor.

Why Does DAIVIN! See Oxygen as an Energy Problem?

DAIVIN!’s long-term vision rests on a fundamental insight: oxygen delivery is governed by energy, not transportation. Wherever logistics are fragile, on-demand generation outperforms storage and transport.

In crisis zones or at high altitude, carrying heavy tanks is inefficient and risky. Water, by contrast, is easier to source and safer to transport. Converting it into oxygen with electricity—whether from batteries, solar panels, or other power sources—offers a more resilient solution.

This logic scales naturally to space exploration. Pressurized oxygen tanks have strict limits, while water and ice are abundant resources already planned for life-support systems. In space, the future is not transporting air, but extracting oxygen from ice using energy.

What Could DAIVIN!’s Technology Mean Beyond Diving?

The principles behind DAIVIN!’s system apply far beyond underwater environments. In aviation and healthcare, oxygen delivery still relies on bulky tanks or legacy systems like pressure swing adsorption, which consume space and deliver lower-purity oxygen.

From first principles, water plus electricity yields extremely high-purity oxygen with fewer mechanical constraints. This opens possibilities for compact, on-demand oxygen systems in aircraft, hospitals, disaster relief operations, and remote medical care.

By shifting the paradigm from containers to sources, DAIVIN! suggests a future where oxygen is generated where and when it is needed, reducing waste, cost, and risk across industries.

What Is the Broader Vision Driving DAIVIN!’s Future?

DAIVIN! ultimately argues that humanity has been solving the wrong problem. For decades, engineers have focused on building better containers for oxygen instead of better ways to access it. The company’s guiding belief is simple: bring the source, not the container.

Starting underwater, DAIVIN! aims to prove that breath autonomy is possible, safe, and scalable. From there, the same first-principles thinking extends to land, air, and space. Wherever humans operate in extreme environments, the ability to generate oxygen on demand could redefine what is possible.

In reframing oxygen as an energy problem, DAIVIN! positions itself not just as a diving equipment manufacturer, but as a foundational technology company shaping the future of human survival beyond familiar boundaries.
