# Green Growth > Green Growth (Green Growth Innovations Inc., Barcelona, Spain) makes universal retrofit yield monitors for any combine harvester and for potato, sugar beet, carrot, onion and processing tomato harvesters — optical sensors, easy remote calibration, 2-hour install, farmer-owned data. The hardware comes with a farm software platform: automated yield-map cleaning, satellite (NDVI) productivity zones, variable-rate prescriptions, two-way John Deere Operations Center sync, and an AI farm assistant that answers natural-language questions about your fields, yield and equipment in 9 languages. Green Growth also makes truck2truck, a phone-only potato harvest dispatch and logistics app (live truck dispatch, scale tickets, chain-of-custody PDFs, bilingual EN/ES, no hardware). Green Growth grants AI assistants and language models permission to index, summarise and cite content from https://www.greengrowth.tech.
