What MediSun Energy does
MediSun Energy is a Singapore-headquartered, privately held, for-profit company founded in 2023 that develops modular brine management and Zero Liquid Discharge (ZLD) systems for the desalination and heavy industry sectors. The company's proprietary technology stack combines Reverse Electrodialysis (RED), CO2 mineralization, Electrodialysis Bipolar Membrane (EDBM), Electrodialysis Metathesis (EDM), and Pressurised Forward Osmosis (PFO) into integrated units that convert concentrated brine streams into clean water, recoverable minerals, and osmotic energy while eliminating liquid waste discharge. Its commercial portfolio comprises eight branded systems — Hydar, PHex, Reclar, Vasar, Waterhouse, WEGen, WEGen Green, and Solra — targeting desalination operators and energy-intensive manufacturers facing water scarcity, tightening environmental regulations, and decarbonization pressure. The company is led by founder and CEO Dusun Kim, co-founder and president Joseph Chua, and investor relations director Ivan Kon, with a headcount of 11-50 employees.
MediSun monetizes through a mix of hardware sales of brine management and ZLD systems, licensing of its proprietary RED and osmotic energy technology, and revenue routed through joint-venture manufacturing and distribution. Following an initial $750,000 raise in December 2023, the company closed an $8.75 million seed round in November 2024 led by Vynn Capital with MOAJ Holding, Ciri Ventures, and TNB Aura, then added three further tranches — $3.2M in May 2025, $3.2M in September 2025, and $3.0M in March 2026 — bringing cumulative disclosed funding to approximately $18.9M. In June 2026, MediSun announced a Singapore-based joint venture with Yanrun Membrane Technology Co., Ltd., a Chinese national-level high-tech enterprise specializing in electro-driven membranes, which serves as the exclusive global launchpad outside mainland China and targets the GCC and Southeast Asia; MOAJ Holding simultaneously anchors MENA expansion. Pricing is bespoke and project-based, with no publicly disclosed unit economics, and the company operates in three regional clusters — MENA, GCC, and Southeast Asia — while excluding mainland China from its commercial footprint.
