See Every Weed. Spray Only
Where It Matters.

Heimdall turns the DJI drone you already own into a full-season precision agriculture system — detecting weeds, fungi and pests at field level, then building variable-rate prescriptions, nutrient plans, resistance tracking and audit-ready records. Everything runs on your own Mac. Nothing ever leaves your farm.

Blanket spraying is expensive.
Scouting on foot doesn't scale.

Input Costs

Herbicide prices have risen 40–60% since 2020. Applying full rates across an entire field when only part of it has a problem isn't agronomy — it's habit.

Resistance

Black-grass and wild oat are losing sensitivity to ACCase and ALS chemistry across Northern Europe. Blanket spraying accelerates it. Targeted application slows it — and Heimdall tracks whether it's working.

Time

A thorough walk of a large field is hours you don't have, and a handwritten scouting note is no longer convincing evidence at an audit.

Spend Less on Chemistry. Protect More Yield.
Prove It Automatically.

Heimdall is the digital eyes on your field. On-device AI identifies weeds, fungi and insects by species, decides cell by cell whether treatment actually pays for itself, and writes the evidence trail while it works. You spray less, you protect yield where it matters, and your audit documentation builds itself in the background.

Precision, not panic

When you know exactly which species is where, and how dense, you stop treating 100 hectares to deal with a problem in twenty. Spot-treat, save the chemistry, and slow resistance at the same time.

See the yield you protected

Heimdall estimates protected yield from the EPPO PP 1/52 loss model — e.g. "at BBCH 25 with 18% weed density, untreated loss would have been ~7.6%." A number you can put against your input bill.

Your farm, your data, your decision

Everything runs offline on your Mac. No imagery, no field coordinates, no crop data ever leaves the device. You get the intelligence; you keep control.

Audit-ready by default

Heimdall scores every season against EU IPM criteria and exports a signed PDF — documented monitoring, threshold-based decisions, spatial targeting and an evidence trail. Compliance stops being paperwork and becomes a by-product.

From Flight to Prescription in Four Steps

Map Your Field

Draw the boundary, enter your crop and sowing date. Heimdall loads the agronomic profile — growth-stage model and economic thresholds — automatically.

Fly the Drone You Own

Export a precision waypoint mission. Heimdall sets the altitude for your chosen cell size and follows terrain over slopes, so every image is sharp and correctly placed.

Analyse on Your Mac

Import the SD card. On-device AI (Apple Neural Engine) detects weeds, fungi and insects species by species, and computes RGB vegetation indices (ExG and VARI) for every cell — entirely offline.

Export Your Prescription

Generate a variable-rate map as Shapefile or GeoJSON — standard formats most modern sprayer terminals and farm-management systems can import. Spray where it matters. Skip where it doesn't.

One Flight Answers One Question.
A Season of Flights Runs the Farm.

Heimdall doesn't stop at weeds. Every flight feeds a season-long picture that gets sharper over time — and the same imagery you already captured drives decisions from drilling to combine.

Species-level detection

EPPO-coded identification of weeds, fungi and insects. Black-grass is not chickweed, and Heimdall assigns the right herbicide group — graminicide or broadleaf — cell by cell.

Economic thresholds that move with the crop

Treatment thresholds adjust automatically for growth stage (BBCH) and species competitiveness. You spray at the right moment — not a moment too early.

Variable-rate nitrogen

After a few flights, Heimdall maps crop vigour from canopy and greenness and builds a per-cell nitrogen plan — more where it pays, less where structural limits mean extra N is wasted.

Resistance monitoring

Heimdall watches whether a species keeps rising after you've sprayed it, separates genuine resistance signals from normal weed growth, and suggests HRAC mode-of-action rotations before the problem entrenches.

Seed bank & cover-crop planning

It flags the species that keep coming back season after season and recommends a cover crop chosen to suppress them — cutting next year's herbicide bill before drilling.

Manure-spread uniformity & harvest planning

Compare before/after imagery to score how evenly manure was applied, catch overlaps and watercourse-buffer breaches, then plan the combine from a maturity, lodging and disease map at harvest.

From the first post-emergence scout to the harvest briefing, it's one tool, one dataset, the whole season.

Grow Into the Fleet.

Heimdall runs the same analysis whether you fly a pocket Mini or an enterprise RTK platform. Start with the entry tier and upgrade your sensing — not your software — as your needs grow.

Entry

DJI Mini Class

The most widely owned precision-class drones in Europe. Under 250 g, no remote-pilot licence required to fly the C0 models. Full cell-level weed, pest and disease analytics straight out of the box.

Mini 3 Pro Mini 4 Pro Mini 5 Pro Neo Air
Professional

Mavic & Air

Larger sensors and longer flights for advisors and contractors covering many fields a week. (Flying these requires the appropriate EU drone licence — A1/A2 or A3 by class.)

Mavic 3 Air 3
Enterprise

Matrice RTK

Centimetre RTK positioning unlocks orthomosaic generation for the highest-precision mapping. For service providers and large operations running fields at scale.

Matrice 4E M30 M350 RTK
Works with standard DJI Fly on the consumer tier and DJI Pilot 2 on enterprise. No third-party SDK.

Built for the People Who Farm at Scale

If you advise growers or fly fields for a living, Heimdall is leverage. Turn a flight into a defensible, species-level recommendation. Hand each client a signed IPM and prescription record as a deliverable. Run the same workflow across every field you cover — and spread one tool across your whole book of business.

  • Defensible advice — every recommendation backed by dated, geo-located, species-level evidence.
  • A billable deliverable — signed PDF reports clients can take to their own audits.
  • Scales across clients — one workflow, every field, from Mini to RTK.
Talk to Us About Professional Use

Smarter Every Flight. Sharper Every Season.

Heimdall accumulates evidence over time, smoothing single-flight noise into a stable picture of each cell — so a passing shadow never reads as an infestation. And the optional contributor programme lets you submit annotated images from your own region; approved submissions refine the detection models for the crops and climates you actually farm.

Better regional accuracy

Your local black-grass ecotype or regional fungal strain gets seen and learned.

Faster model updates

Contributor submissions trigger priority refinement cycles.

Lower maintenance cost

100+ approved annotations a year qualifies you for the contributor rate.

In the Field Now

Heimdall is in field trials across arable farms in Germany, the Netherlands and France. Early access is open.

Built and maintained in Europe, for European farmers.

Your Farm. Your Data. Full Stop.

Every analysis runs on your Mac via the Apple Neural Engine. No imagery, no coordinates, no field data is ever transmitted. The single optional network call is an anonymous weather lookup using only your field's approximate location — and the software runs fully without it.

You can verify it with any network monitor: the only outbound connection you'll ever see is to the weather service.

No subscription to use. After your first year of updates, the software keeps working forever on the version you own. Maintenance is optional.
