The Earth speaks in chemistry

Continuous chemical monitoring across agricultural and environmental systems, from crop disease to invasive species, catching what satellites can't see.
What we do
General Sense captures chemical telemetry from  agricultural fields, water systems, and natural environments.
the problem

The cost of finding out too late.

Crop disease and invasive species drain hundreds of billions of dollars a year from farms, forests and waterways. Nearly all of that money goes to damage after the fact, and very little to catching problems early.

Herds and wildlife
Support animal-disease response, from routine barn checks to the carcass searches dog teams already run during African swine fever outbreaks.

invasive species

Invasions are won or lost while they're still small.

Request a pilot
Every agency fighting invasive species runs the same playbook, early detection and rapid response, and detection is the weak link. Visual surveys and traps tend to find an invasion once it is large enough to see, when eradication costs far more or is no longer possible. Detection dogs find the egg mass, the larva under the bark and the mussel on the hull while a population is still small enough to remove.

the evidence
Ecology and Evolution review: across 34 head-to-head studies, detection dogs beat human surveyors and other methods 91% of the time.

Every acre of farmland, every watershed, every supply chain node emits a chemical signature.

already on the job

Dogs already guard the food supply.

Detection dogs are a standard tool in agriculture and conservation, documented in 62 countries and used to find more than 400 animal species, 42 plants and 26 fungi. The kennels, handlers and budgets already exist.
Ports of entry
More than 160 beagle teams screen luggage and cargo for prohibited plants, meat and pests. Congress wrote their training center into law in 2024.

Today: trained dog teams through our K9 partners. Next: a neural readout designed to report many targets at once.
how we fit in

Built to drop into programs that already work.

See the technology
General Sense partners with established K9 providers, so a program keeps the dogs, handlers and routines it already runs. Today, adding a new target means retraining every dog, one odor at a time. Our neural readout is designed to let one dog report many targets in a single pass, with each search logged by time and place, so every walk through an orchard, port or watershed adds to its chemical record.

Before It's Visible, It's Detectable

Read the case studies
Crop disease, contamination events, and invasive species emit chemical signatures weeks before they show up on any satellite image. In the USDA study's 10-year model of citrus greening, groves surveyed by dogs kept more than 92% of their trees healthy, while groves surveyed by eye kept none. Proactive management can prevent millions in losses.

earth-sensing infrastructure

The chemical layer of Earth observation.

Satellites record the planet's light, weather stations its physics, and eDNA and microphones its biology. The airborne chemistry that first signals a pest, a pathogen or a leak still has no network. A dog team is a mobile sensor that can be sent wherever a reading matters most, and over time those readings give models of the planet the chemistry they have been missing.
Detect
Find the first signs of a pest, pathogen or contamination while there is still time to act.
Verify
Confirm that an eradication or cleanup worked by checking that the target is really gone.
Baseline
Repeated searches build a chemical record of each farm, forest and port, so the next change stands out against it.
