Kinestral Technologies Inc., developer and manufacturer of Halio smart-tinting glass, has closed Series D funding of more than $100 million led by SK Holdings, a large conglomerate in South Korea. Current investors 5AM Ventures, Alexandria Real Estate, Capricorn Investment Group and Versant Ventures also participated in the round. This investment will allow Kinestral to expand manufacturing, sales and installation of Halio smart-tinting glass to meet growing global demand, according to the company.

“We are excited that SK Holdings shares our vision of Halio being in every building and every home,” says S.B. Cha, CEO of Kinestral Technologies. “… With SK Holdings’ support, we will make Halio the standard of smart buildings and homes so that people everywhere can live in harmony with natural light.”

Halio is sold exclusively through Halio North America and Halio International, joint venture companies that Kinestral formed with AGC Inc.
