A Japanese start-up is using satellite data and AI to provide soil analysis. This helps farmers in developing countries improve income by increasing yields, improving crop quality and minimizing unnecessary costs. Around 70% of Indians are farmers, but have small plots and falling incomes. Partnering with local agricultural firms, the firm now serves 4,000 farms who've seen bigger harvests, less chemical fertilizer and more income. The firm is also expanding into Thailand, Vietnam and Kenya.
