AI-powered food waste prevention for foodservice operators
You run kitchens you don't own, to standards your clients set, across sites that rarely operate the same way twice. Winnow measures what actually gets thrown away, site by site, client by client. Caterers use it to drive consistency across every client site, control food costs, and hand clients auditable ESG data. Every contract, the same standard.
Trusted by Compass Group and IKEA, in 3,500+ kitchens across 90+ countries.




Benefits for chefs
Bin food as normal. Throw & Go captures weight and image with no scanning, so nothing slows a lunch rush.
See which dishes are being over-prepped, not just that waste went up this week, with item-level data.
Rank waste by weight and cost every day, so you adjust prep before the next service rather than after the month.
Capture food waste automatically. Throw food away as normal and Throw & Go identifies and records it. No scanning. No hassle.
Why foodservice operators choose Winnow for food waste prevention

Waste you could never measure by hand
Foodservice waste arrives as hundreds of small disposals across shifts, counters and sites. Manual logs are slow and inconsistent, which is why most of it goes unmeasured. Winnow captures all of it automatically.

Item-level data, not a monthly total
Winnow shows which items are overproduced, expired or repeatedly discarded, so teams fix the cause rather than reporting the symptom.

Auditable data for client ESG reporting
Every disposal is weighed, timestamped and photographed, then exported by client with cost and CO₂e attached. Commitments arrive with evidence rather than intentions.

Adoption that survives turnover
Recording is fully automatic, with no category to select and nothing to remember mid-service, which matters where staff change often and retraining every rotation is not realistic.
