MediSun Raises $8.75M Seed Round, Partners with Vynn Capital to Advance Osmotic Energy

MediSun Energy, a Singapore-based clean technology company focused on advanced osmotic (blue) energy solutions, has secured US$8.75 million in seed funding. The investment comprises US$5 million in venture debt and US$3.75 million in equity, elevating the company’s valuation to US$44 million. The funding round was spearheaded by Vynn Capital’s Mobility and Supply Chain fund.

The funding round, led by Vynn Capital, attracted several new investors, including Saudi Arabia’s MOAJ Holding, TNB Aura, Frank Phuan, and Ciri Ventures. MOAJ Holding has committed up to US$30 million to support MediSun’s expansion in Saudi Arabia, where a local joint venture will be established. This partnership will play a pivotal role in accelerating MediSun’s growth in the Middle East and North Africa (MENA) region.

The funds will be used to establish two key facilities: one for membrane production and another for stack production. These facilities will boost MediSun’s ability to scale its operations and meet the growing demand for its advanced osmotic energy technology. 

MediSun Energy’s solutions, such as its zero-brine technology, aim to provide clean, renewable energy while promoting a more sustainable future. The company’s WEGen technology utilizes osmotic power to improve energy efficiency in water desalination processes, addressing global water scarcity and energy challenges.

Dusun Kim, Founder and CEO of MediSun, emphasized the importance of this investment in scaling the company’s impact. “This partnership is a significant milestone for MediSun, enabling us to expand our operations, bring our solutions to new markets, and tackle critical environmental challenges,” he said. 

Victor Chua, Founding & Managing Partner of Vynn Capital, added, “MediSun’s technology addresses both water supply chain issues and energy efficiency, making it essential for achieving net-zero carbon goals across various industries.”

Vynn Capital believes that MediSun’s technology plays a key role in addressing water supply chain issues and scarcity while contributing to net-zero carbon goals by improving energy efficiency. 

Victor Chua also highlighted the potential for MediSun’s osmotic energy solutions to extend beyond the water sector. He sees applications for the technology in industries such as mobility and manufacturing, where energy management and sustainability are becoming increasingly important.

As part of its strategic vision, Vynn Capital is also exploring additional opportunities in Southeast Asia, with a particular focus on markets like Singapore, Thailand, and Indonesia. The region’s water technology market is expected to experience substantial growth, and this partnership positions both MediSun and Vynn Capital as leaders in driving innovation and sustainability within the sector.
