German agritech startup eternal.ag has raised €8 million in funding to advance its autonomous harvesting robots, aiming to make greenhouses fully automated. The investment, led by Simon Capital alongside Oyster Bay Venture Capital, EquityPitcher Ventures, and Backbone Ventures, will accelerate the company’s European expansion and extend its technology to new crop types.

Eternal.ag’s robots are designed to address the growing labour shortages in greenhouse farming, which have declined by 30 percent in Europe since 2010. The startup’s flagship product, Harvester, is a fully autonomous robot tailored for tomato greenhouses. Operating up to 22 hours a day, Harvester uses AI to ensure consistent quality and precision, while its modular design allows for future upgrades to support broader greenhouse operations.

“Autonomous robots only work if they can handle real-world variability between plants, layouts, and daily operations,” said Renji John, CEO and co-founder of eternal.ag. “We develop and validate our robots using simulation-first development. That allows us to train, test, and fail safely in virtual greenhouses – cutting iteration cycles from months to days. Once deployed, every robot action feeds data back into the system, which is designed to learn, improve, and scale.”

Eternal.ag envisions fully automated greenhouse operations powered by robotics by 2040, eliminating the need for manual labour.

Founded in 2025 by Renji John and Sherry Kunjachan, eternal.ag operates from its headquarters in Cologne, Germany, with an additional office in Bengaluru, India. The company’s 26-person team is focused on developing cutting-edge technology to eliminate labour uncertainty in greenhouse operations.
