Eternal.ag Secures €8M to Advance German Agritech

A Cologne-based startup is pioneering a new path in agricultural robotics by training its machines in highly detailed virtual environments before they ever touch a real plant. Eternal.ag has secured €8 million in funding to advance its simulation-first development approach, aiming to solve the persistent industry challenge of reliably automating delicate greenhouse harvesting tasks. This fresh capital injection will fuel product development and commercial expansion across Europe, targeting the acute labor shortages threatening the continent’s greenhouse horticulture sector.

The core challenge in greenhouse automation is immense. Robots must handle irregular, delicate produce like tomatoes and cucumbers within a humid, densely packed environment where every plant is unique. Numerous startups have produced robots that perform well in controlled demonstrations but consistently fail when required to operate commercially for twenty-two hours a day. This stubborn gap between laboratory success and real-world reliability has stalled widespread adoption for years.

Renji John, Eternal.ag’s co-founder, is intimately familiar with these hurdles. His previous venture, a Dutch agritech company building similar autonomous robots, ceased operations in 2023. His new company, founded with Sherry Kunjachan, is applying lessons learned through a fundamentally different technical strategy. The startup’s entire development process revolves around simulation. Engineers build, test, and validate robotic systems inside virtual greenhouses powered by NVIDIA’s Isaac Sim platform long before physical prototypes are deployed.

This methodology aims to drastically compress innovation cycles. By running countless failure scenarios in software, the team can iterate in days rather than the months typically required when testing involves costly hardware and actual crops. Once robots are deployed in partner greenhouses, every action generates data that feeds back into the simulation for continuous refinement. While the promised operational figures and development speed are company claims, the underlying philosophy mirrors risk-management practices used by leading robotics firms.

The company’s initial commercial focus is a modular autonomous harvester for tomatoes. Designed as part of an AI-driven system that manages cut quality and consistency, this platform is intended to eventually handle other greenhouse tasks. The long-term ambition is to achieve fully autonomous greenhouse operations by 2040. The recent funding round was led by investors with strong sector alignment, including Simon Capital, Oyster Bay Venture Capital, EquityPitcher Ventures, and Backbone Ventures.

Investors are betting on the urgent need for a technological solution to a deepening structural problem. European greenhouse growers have long relied on seasonal migrant labor, a pool that has significantly contracted. This creates a pressing operational constraint for an industry that requires consistent, physically demanding work year-round. Automation presents a compelling, future-proof answer to building a more resilient food supply chain, even if its execution has historically been fraught with difficulty.

The new capital will accelerate product development, support wider European deployments, and fund expansion to additional crop types. For John, this second attempt is informed by the precise reasons the first venture stumbled. The company’s measured strategy,emphasizing simulation, modular design, and gradual crop expansion,appears to be a conscious effort to build more deliberately than a typical fast-moving startup. The coming years will determine if this disciplined, virtual-first approach can finally bridge the gap between promising technology and durable, large-scale commercial success in the greenhouse.
