Saga Robotics

Saga Robotics is an agricultural technology company pioneering autonomous robotics for sustainable crop protection. Its flagship platform, Thorvald, is a modular autonomous robot that delivers precision UV-C light treatment to manage disease in high-value specialty crops—most notably wine grapes.
Rather than relying on chemical fungicides, Thorvald uses ultraviolet light to control fungal pathogens like powdery mildew directly in the field, operating autonomously through vineyard rows day or night. The technology offers growers a dual mechanism of action: direct pathogen suppression combined with activation of the plant's own natural immune defenses, supporting both disease control and long-term vine resilience.
Saga Robotics serves premium wine regions and sustainability-focused growers seeking to reduce chemical inputs while protecting yields and vineyard health. By preserving beneficial native microbial populations that conventional copper and sulfur programs suppress, Thorvald aligns crop protection with regenerative and organic farming goals.
With a growing footprint across California and leading European wine regions, Saga Robotics is helping the agriculture industry transition toward chemical-free, data-driven, and environmentally responsible farming—delivering measurable value to growers while advancing a more sustainable future for winegrowing.
