Stardust
Deployable Systems Stabilize Earth's Temperature through Sunlight Reflection
Company Overview
Snapshot
Founded in March 2023 by Yanai Yedvab, Stardust operates with 11–50 employees. The company has raised $75M across two funding rounds from four investors. In April 2025, Stardust secured A-round funding with participation from Exor.
Business overview
Stardust is developing a full-stack solution for Sunlight Reflection Technology (SRT), a method designed to stabilize Earth's rising global temperature by reflecting incoming solar radiation. The system utilizes specialized atmospheric particles made from naturally occurring, chemically inert materials, high-altitude deployment systems, and real-time atmospheric monitoring sensors with predictive modeling. This approach provides a safe, measurable, adjustable, and fully reversible system intended for planetary-scale operation, offering a deployable option to mitigate near-term temperature extremes and protect critical ecosystems. Stardust operates within the Industrial Technologies sector, focusing on climate tech and sustainable materials.
Strategic signal
In October 2025, Stardust garnered significant attention for its sun-reflecting technology, raising $60 million to advance testing. This funding highlights increasing investor confidence in climate intervention technologies and signals a growing market interest in scalable solutions for global temperature stabilization, positioning Stardust as a key player in the emerging field of climate engineering.
