Per-trip temperature proof and sell-first calls for frozen food shippers
TL;DR Frozenproof gives brands that ship ice cream, frozen snacks and chilled dairy in hired reefer trucks a temperature record for every trip, measured at the product and not just the air. Each consignment gets a sell-first, hold or reject call. Brands pay per trip and use the record to settle disputes with transporters.
Cold goods spoil in transit, and the loss is huge. A 2022 study for the food processing ministry valued India's post-harvest losses at ₹1,52,790 Cr a year, with milk, meat and fish alone at ₹29,871 Cr[1]. Packaged frozen food isn't counted there, but it rides in the same hired trucks.
Temperature breaks are common even in well-run fleets. In a 2024 export trial, standard refrigerated containers logged 45 to 52 breaks per voyage, averaging 20 to 31 hours each[2]. So when does a brand that hires a truck from a small operator find out about a break? Usually when a retailer rejects melted stock, and by then nobody can prove where it happened.
Frozenproof puts reusable loggers inside cartons, not only on the truck wall, because the air near a sensor can be far from what the product feels. A review of cold-chain studies cites one trial where a single air sensor got 97% of its low-temperature alarms wrong[3]. That's a lot of false alarms. Loggers sync to a phone app at loading and unloading, and in real time where the trip justifies a cellular unit.
At the receiving end the app scores each consignment from its temperature history - sell first, hold for a quality check, or reject. The trip record, signed off by both sides at handover, becomes the evidence in any claim against the transporter.
I narrowed the seed, which promised prediction of spoilage before it happens. The same review found no study that forecast breaks or their causes in advance[3]. Frozenproof sticks to what the data supports, which is recording, proof and shelf-life estimates after the fact.
The brand owner pays, meaning the supply-chain or quality head of an ice cream, frozen food or dairy company that hires reefers rather than owning them. Pricing would be per trip or per logger per month (my assumption). Their current cost is the rejected stock and write-offs they can't pin on anyone. Transporters may later pay to show a clean record and win contracts.
The cold-chain trucking market is getting organised. One cold-chain trucking platform has raised ₹100 Cr and connects 200+ reefer partners across 40+ cities with live tracking[4], so brands are getting used to digital trip data. India's DPDP Rules, notified in November 2025, now set clear consent duties for driver data[5].
There's no public figure for spending on cold-chain monitoring in India. The firmest loss number is the ₹29,871 Cr a year lost in milk, meat and fish[1]. If you want a real number then count it bottom-up - the frozen and chilled brands in a region, times their monthly reefer trips.
That trucking platform runs a reefer and cold-storage network with location and temperature in its app[4], but it's the carrier side, so a brand's dispute is with the platform's own partners. A global cold-chain monitoring firm sells loggers and software that judges temperature excursions worldwide[6]. A US shipment-tracking firm sells real-time shipment visibility and covers India from its EMEA sales team[7]. The gap is a cheap, neutral record that a mid-sized Indian brand can use with any small transporter.
| Difficulty | Moderate (43/100) |
| Starting capital | ₹60 L–1.2 Cr |
| Time to launch | 6–9 months |
The loggers are standard parts. The hard parts are getting carton-level readings back from every trip without losing devices, and building sell-first scores that quality teams trust. Transporters may resist anything that gives evidence against them, so your first few brands must be willing to insist.
No food licence, since you never handle the food. The loggers are radio devices though, so equipment rules apply.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI to predict breaks before they happen. Research has found no study showing that works[3], and a reject call on food still needs a person's sign-off.

Here's what can go south -
A sensible business if you know cold-chain operations and have sold to quality teams at food companies. If you want to sell predictions then it's a weak fit, honestly. Prove first that brands will pay per trip once they see a month of carton-level records from their own lanes.
Plan for roughly ₹60 L–1.2 Cr, mostly for loggers, the app, device approvals and the first pilots.
You don't need a food licence, but wireless loggers need WPC type approval and some electronics need BIS registration. Driver data falls under the DPDP Act.
Yes. Frozen food shippers everywhere fight over temperature claims. Check local radio equipment approvals and data protection rules before you ship devices.

Thinking about building Frozenproof or something close to it? The make-or-break work is getting brands and transporters to accept one shared record of every trip, and that's the kind of thing I help founders figure out. If you need a hand, you know where to find me. Talk to Yash →
