Synthgen
Precision weeding & spraying · green-on-green

Onboard a new crop in days, not weeks.

Realistic, already-labelled field images of a new crop — so your robot tells weed from crop on roughly 5× fewer real photos.

Precision weeding & spraying — placebo-controlled, validated in your vertical, replicated on a second independent dataset.

Data efficiencyper new crop
~10 vs ~50 labels
with synthetic pre-training~10 labels
real-only~50 labels
≈ 5× fewer labels for the same accuracy

Placebo-controlled in precision weeding: synthetic pre-training reaches the same accuracy with roughly 5× fewer labelled images — biggest gains exactly where weed and crop are both green.

What you actually get

The missing photos, already labelled.

Real, already-labelled training images generated by Synthgen: new plants placed into the field at true scale, grounded and lit to sit naturally — every one auto-labelled weed or crop as it's made. No hand-annotation.

Source imagery: WE3DS crop/weed dataset (Kicherer et al.), CC BY 4.0. Synthetic images + labels by Synthgen.

The offer

The crop-onboarding benchmark.

Send us your next crop. We build synthetic pre-training data from your own field imagery — auto-labelled, pixel-exact — then benchmark it against your real-only baseline on your own fields, under placebo controls so the lift is real. You name the bar before we start (say: today’s accuracy at a fraction of the labels), and you pay only if we clear it.

Pay on results — you set the bar, we clear it or you don’t pay. No free pilots, no free work: just a measured answer.

Before / after

The old way, retired.

A new crop onboarded in days
Hand-labelling every image
Labels attached at generation — pixel-exact
Green-on-green is where accuracy dies
Green-on-green is where the gains are biggest
Nobody measures crop plants wrongly hit
The safety axis, measured and reported
The proof

Measured, not promised.

crop plants wrongly hit at matched weed recall in our validation — vs 4.4% for the baseline. The safety axis no one else measures.

Placebo-controlled on real held-out field images in our precision-weeding validation — and replicated on a second, independent field-robotics dataset, where 15 labelled images plus synthetic pre-training took a weed detector from unusable to working. Your number comes from your own fields.

Edge-ready: with synthetic pre-training, a nano model at 640 px matched a real-only model at 1280 px in our validation — headroom your onboard compute will feel.

Why the number holds

Honest in both directions.

01

Placebo-controlled, always.

Anyone can show a lift that’s really just more data. Every claim we make has survived placebo-controlled benchmarks — if the gain isn’t real, we don’t publish it.

02

The safety axis.

A weed left standing costs a pass; a crop plant burned costs the row. We measure crop plants wrongly hit at matched recall and report it next to the accuracy number.

03

Your fields, not a render farm.

Built on your own field imagery, with pixel-exact labels — faithful to how your crops and weeds actually look, not stock photos or guesswork.

How the benchmark runs

Two weeks to the answer — then days per crop.

Day 1

You send field photos of the new crop, with labels for a small starter set, and we agree the class map.

~1–2 hrs of your engineer

Days 1–3

A short fit check on your imagery and classes — we only run benchmarks we expect to win.

a short call

Week 1–2

We generate the synthetic training data from your imagery, pre-train, fine-tune, and benchmark it under placebo controls.

nothing from you

By week 2

A measured answer on your held-out field images: accuracy, label count, and the safety readout.

30-min readout

After

A win becomes a pilot — a one-month engagement at minimum — then every new crop, region, or season onboarded the same way.

Agricultural results are detection results from our precision-weeding validation — placebo-controlled on real held-out field images; crop-safety measured at matched weed recall. Results are per crop and produced on your own data, against a bar you set before we start.
