Battery-free tags read at every dock door, cold room, and truck threshold. A temperature record for every pallet — not just every truck.
Cold chain is observed at two tiers today. Manual logs and chart recorders are easy to skip, falsify, or backfill — they prove compliance on paper without preventing loss. Active data loggers cost fifty to several hundred dollars per node and run on batteries that die; their economics work for whole-truck or pharma shipments, not for every pallet.
Cuddlefish is the third tier: ambient-power tags at sub-dollar economics, dense enough to live on every pallet, every case, every monitored asset. Temperature data without batteries, without IT projects, without spreadsheets.
Passive UHF RFID with on-chip temperature sensing. No battery, no maintenance window, no per-device subscription. The radio field that reads the tag also powers it.
Cuddlefish is the second RFID startup for this team. The first was at Kroger, in cold chain — the same problem, in the era before the unit economics worked. They do now.
