Denied claims
Carriers reject loss claims when you can't prove exactly when and where the temperature broke.
Cold-chain intelligence for small shippers
Prove the cold chain held — without enterprise pricing.
Thawline gives shippers of specialty seafood, biologics samples, and artisanal dairy defensible, court-and-claim-ready proof that temperature held end-to-end — at a price built for small operations, not enterprise budgets.
A thawed shipment is only the start of the problem
When high-value perishables arrive warm, the loss is rarely the worst part. Without defensible end-to-end proof, you can't win the claim, hold a carrier accountable, or protect the next shipment — and enterprise-grade monitoring is priced out of reach for small shippers.
No accountability
Without a continuous record, no one is held responsible — and the failure repeats.
Priced out
Enterprise cold-chain monitoring assumes enterprise volumes and enterprise budgets.
Blind handoffs
Every transfer is a gap where the chain can break unseen until the package arrives warm.
From sensor to defensible proof
Thawline turns continuous temperature data into a record you can stand behind — for claims, audits, and accountability.
