Tule

What Tule does

Tule Technologies was a US-based precision irrigation company that specialized in evapotranspiration (ET) monitoring, canopy sensing, and water stress measurement for specialty crops, with primary application in California vineyards. Founded in 2013 and headquartered in San Francisco, Tule developed proprietary technology that enabled plant-level water stress assessment from smartphone-captured canopy images across entire vineyard blocks, eliminating the need for specialized equipment. Its core products included the FieldStat ET monitoring engine (later rebranded as ET Index under CropX), mass balance-based irrigation recommendations, and canopy sensing analytics — all delivered through a self-serve SaaS platform accessible via web browser and native iOS/Android applications.

The company operated a product-led growth model with a free mobile app, demo booking via Calendly for sales-assisted conversions, and regional sales contacts across North America, Europe, Australia, New Zealand, and Latin America. Tule's customer base consisted primarily of wine grape growers in California seeking scalable water stress monitoring and irrigation optimization. Its revenue model was subscription-based SaaS, though specific pricing tiers were not publicly disclosed.

In January 2023, Tule Technologies was acquired by CropX Technologies, a US-based agri-tech company, ending its independent operations. Following the acquisition, Tule's canopy sensing technology, ET monitoring capabilities, and user data were integrated into the CropX unified agricultural intelligence platform. The technology has since been productized globally as CropX Vision (launched 2026), an AI-powered vineyard monitoring solution, with Tule's mass balance irrigation logic enhanced by a neural network for sharper recommendations.

Core offering

Tule developed and operated a cloud-based precision irrigation SaaS platform that delivered evapotranspiration (ET) monitoring, canopy sensing, and water stress measurement for vineyards and specialty crops. The platform provided plant-level irrigation recommendations using mass balance logic and allowed growers to monitor entire vineyard blocks via smartphone-captured canopy images. Following its January 2023 acquisition by CropX Technologies, Tule's core offerings (ET Index, canopy sensing, irrigation recommendations) have been integrated into the unified CropX agricultural intelligence platform, with CropX Vision now extending the canopy sensing IP globally.

Product overview

Tule has transitioned into the CropX platform, a unified agricultural management system that combines ET monitoring, soil sensing, weather data, and irrigation management. The core offering includes the CropX Platform with integrated modules: ET Index (formerly FieldStat) for evapotranspiration monitoring, Irrigation Recommendations enhanced with neural networks, CropX Vision for AI-powered canopy image analysis, and an Overview Widget for field status dashboards. All features are accessible via web and mobile applications, with historical Tule data fully preserved in the unified system.

• AquaSpy: AquaSpy manufactures multi-depth soil moisture and salinity probes that drive irrigation scheduling for row crops and specialty crops. It competes with Tule in the irrigation optimization and water stress analytics category, using hardware sensors instead of canopy imaging.
• Semios: Semios is a precision agriculture platform focused on specialty crops including tree fruits, nuts, and vineyards. It provides crop monitoring, pest management, and irrigation analytics — directly comparable to Tule's canopy-based water stress monitoring for high-value crops.
• Davis Instruments: Davis Instruments manufactures weather stations, soil moisture sensors, and EnviroMonitor agricultural sensor networks used by growers for irrigation and crop decisions. Comparable to Tule in providing environmental data inputs that drive irrigation scheduling.

Others

• CropX Technologies: CropX is the parent company that acquired Tule in January 2023 and integrated its canopy sensing and ET monitoring technology into the unified CropX platform. Included for ecosystem context given Tule is now a wholly-owned subsidiary rather than an independent peer.

Broad incumbents

• Trimble Agriculture: Trimble Agriculture offers a broad precision agriculture portfolio including guidance, telematics, and water management for farms. Its irrigation-related offerings overlap with Tule's precision irrigation analytics but as part of a much wider enterprise software and hardware suite.
• John Deere (Field Connect): John Deere's Field Connect soil moisture probes and Operations Center integrate field data into farm management decisions. As a major incumbent, John Deere competes with Tule in providing data-driven irrigation insights, especially to large-scale growers.
