The physically intelligent operating system for the open field.
Not a dashboard, not a single-task tool. One cohesive system that runs a farm's daily work and its long-range plan, delivered through a swarm of small, chemical-free robots. Built with and for the small family farms that are most of American agriculture.
Our system is physically intelligent. Agentic. Oh, and chemical-free.
working on food security and chemical-free farming to feed a growing world without taking more of its land.Every acre already encodes what it needs: where weeds push, where the soil tires, where yield leaks. Until now, reading it meant a person in the rows. Tendril reads it, decides, and acts.
Agriculture runs on a chemical treadmill.
548 weed species now resist the chemistry meant to kill them, and the count climbs every year. No new herbicide mode of action has reached the market since the 1980s. The response has been to spray more, on a calendar, across thousands of acres no one sees plant by plant. Resistance compounds. Soil biology thins. Inputs escalate. That is decay, amplified.
- Spray the whole field on a schedule, not on need
- 548 resistant weed species, and climbing
- No new mode of action in forty years
- One look per season, from a truck or a plane
- Small robots in the row, working every day
- Weeds removed mechanically, plant by plant
- Every pass remembered, every acre mapped
- Inputs fall as the field's memory compounds
The chemical era sees the field once a season.
Tendril sees it every day.
Small machines. One agentic loop. Every acre.
Perception, memory, decision, action: four steps tied into a single system that never stops running. That closed loop is the operating system. The same loop runs whether the limb on the end is a weeder, a disease arm, or a seeder.
Perceive
Robots read the field at leaf level. Every plant classified at the source: crop, weed, pest, disease, damage.
Remember
Every pass writes to a persistent map of the land. The system knows what failed last season and watches for it.
Decide
The agentic layer plans the fleet's work against the field's memory and the grower's goals. This is the part no one else has.
Act
Weeds removed mechanically, treatment placed plant by plant. The result is measured and fed back into the loop.
Built on edge vision, persistent spatial memory, and an agentic decision layer that coordinates a modular fleet. The same intelligence stack, repointed from the living room to the field.
The hands of the system:
A coordinated team of small, modular, chemical-free robots, swappable by task and directed by the agentic core. The tendrils of the operating system, in the field.
Not a dashboard. An operating system.
The field is crowded with point solutions: a sensor company here, an app there, a single-task rover somewhere else. Each does one thing, none of them act on their own, and none of them talk to each other. Tendril is the opposite: one agentic system that ties perception, memory, decision, and action into a single stack.
They hand you data. Tendril runs the farm.
Every day on the farm compiles to one file.
The system underneath is complex. .farm is how it stays legible: every day on every field aggregates into one interpretable, exportable file. Every sensor reading, every robot action, every decision the system made, every word from the grower.
It is dynamic, not a static log. The farm-OS agent reads it as a living, complete overview of the land, and the grower can export and own it. Stack the days and you have a record no incumbent can reconstruct.
The farm's many complex, multi-dimensional inputs synthesize into one cohesive .farm file the agentic layer can interpret, then it works with the grower to decide, monitor, and make the changes the field needs. And because there are real robots in the field, execution isn't abstract: the system only commits to what it can deploy, then actuates it.
Execution, not advice.
Built with growers,
not for them.
Family farms are 96% of US agriculture, and most of them are small. Big iron was never designed for them. Tendril is. We design with the grower, for the work they actually do.
Row-crop growers
Corn, cotton, soybeans, wheat. Margins are razor-thin and the iron sits idle most of the year. We attack the single largest line on the farm.
Specialty farms
Where labor runs 50 to 70 percent of cost and almost nothing is automated. The work is repetitive, skilled, and unfillable. The intelligence carries it.
The soil itself
Less compaction, fewer chemicals, biology that recovers. The advantages that make us defensible are the same ones that keep the ground alive.
Small and modular. Like microreactors, not megaprojects.
The smartest hardware in agriculture costs hundreds of thousands of dollars and sits on a single farm. We took the path that worked for power: instead of one massive, centralized machine, a fleet of small, mass-manufacturable, modular units that deploy anywhere and price on the acre.
Built at volume
One design, produced at scale. Unit cost falls as the fleet grows, not up front, per farm.
Swappable by task
Snap in a weeder, a scout, a disease arm. One platform, many jobs, across the whole season.
Within reach
No $400,000 smart tractor to buy. Priced on the acre, for the family farms that are most of US agriculture, and unlike big iron, it ships with a real agentic operating system.
Ten billion people by 2060. The same land, or less.
We can't deforest our way there. The only lever left is efficiency per acre, and that is the company we're building: the system that resists decay in the field, plant by plant, season over season.
Step off the treadmill.
Tendril is the operating system that steps off the chemical treadmill: chemical-free robots and an agentic intelligence layer, built with family farms. We're in development, and if you back founders who choose hard problems, we should talk.
