What Huum does

HUUM OÜ is an Estonian designer and manufacturer of premium electric and wood-burning sauna heaters, founded in 2013 and headquartered in Tartu, Estonia. The company sells a portfolio of nature-inspired heater lines (DROP, HIVE, CLIFF, STEEL, and CORE series in both floor- and wall-mounted variants, plus HIVE Wood and HIVE Flow wood-burning stoves) unified by the UKU smart sauna control system and a multi-language HUUM mobile app that enables remote heating, scheduling, and multi-sauna management. Manufacturing is carried out in Estonia with established local metal processors, and the products have earned three Red Dot Design Awards (2015, 2021) and a 2025 European Product Design Award, positioning HUUM in the premium design-led segment rather than the commodity heater market.

The company generates revenue primarily through hardware sales distributed via a global network of authorized dealers and resellers, complemented by direct e-commerce through five regional storefronts (huum.eu, huumsauna.com, huum.de, huum.jp, huum.ee). End-customer pricing is not publicly disclosed. HUUM serves three primary segments: residential homeowners installing home wellness infrastructure, hospitality and wellness facilities (hotels, spas, saunariums), and corporate offices deploying employee wellness amenities. Named installations span Melbourne, New York, the UK, Norway, Switzerland, and Estonia, with corporate logos including Pipedrive and Monese.

The business has been funded largely through non-dilutive Estonian and Norwegian public grants (Enterprise Estonia 2018 digitization diagnostics; EUR 336,973.50 Enterprise Estonia product development grant 2020-2022; Norway Grants Green ICT funding 2022-2024 focused on energy reduction and AI development) rather than institutional venture capital. Certifications include CE, ISO 9001, SZU, and German BimSchV II, the last enabling sales of compliant wood-burning stoves in one of the world's most stringent regulatory markets. The company is privately held with 11-50 employees and no disclosed institutional investors.
