DAIVIN! is a deep-tech hardware company (Y Combinator Winter 2026, based in San Francisco and Finland) building tankless diving technology. Its core product, SPRING, is marketed as the "world's first tankless diving technology": instead of carrying heavy pressurized oxygen tanks, a diver wears a lightweight vest of electrolyzers and a battery belt that use electricity to split water on demand into breathable oxygen (O2) and hydrogen (H2), targeting depths up to 200 meters / 650 ft. Founder Leo Kankkunen frames breathing as "fundamentally an energy problem," and the company envisions applications beyond recreational and professional diving across space exploration, high-altitude rescue, hospitals, and aircraft. Added to the API Evangelist network as a venture-capital portfolio lead surfaced via y-combinator. Daivin runs a conceptual marketing website (Wix) and a news blog; it publishes no public API, developer portal, SDK, or other machine-readable developer surface, so no API artifacts apply to this provider.
