VesselThe promise
A simple cooler. A small sensor. A record everyone trusts.
Vessel is not a science project. It is a well-engineered cooler with a temperature sensor inside, paired with software that produces a clean, signed record of how every shipment was handled — from the dock door to the pharmacy that opens it.
How it works
One quiet workflow, designed around how cold chain actually moves.
The receiving pharmacy keeps the box (they would reuse it anyway). Only the small sensor comes back to us. The temperature record is yours within hours.
Pack and ship as normal
A right-sized insulated shipper qualified for the product's temperature range, with a small Vessel sensor sealed inside at pick.
Move with confidence
Through every leg of the journey, the sensor captures the full temperature profile and any handling events that matter.
The pharmacy opens it
The box and contents stay with the pharmacy to reuse or recycle. Inside there's a small pre-paid mailer for the sensor — drop it in the next outgoing mail.
Everyone has the record
When the sensor arrives back, we produce a signed temperature record. Manufacturers, distributors, and pharmacies can all see exactly how the medicine was handled.
Why Vessel
Confidence across the chain.
Vessel is built so that everyone touching the shipment — the manufacturer that released it, the distributor that moved it, and the pharmacy that opens it — has access to the same trusted record.
For manufacturers
Confidence that your product traveled the way it was supposed to, end to end. A clean record on file for every dose that left your facility.
For distributors
A simple, reliable shipment record that answers any question about any shipment — quickly, calmly, and with documentation your customers and auditors can trust.
For pharmacies
Open the box knowing the medicine inside was handled properly. The sensor takes 30 seconds to return; the box is yours to keep.
For the pharmacy receiving
Designed to be easy on the people who open the package.
Pharmacies are busy. Vessel is built around what they would do anyway — keep the box, reuse what's useful, recycle the rest. Returning the sensor is the smallest possible ask: drop the pre-paid mailer in the next outgoing pile.
Keep the box
The shipper is yours. Reuse it for your own packouts, send it home with a patient, or recycle it the way you already do.
No new workflow
The sensor lives inside the box during transit. The pre-paid sensor-return mailer is co-located with the carrier label — no scavenger hunt.
Thirty seconds
Open the inner pouch, drop the sensor into the pre-addressed mailer, leave it with your next outgoing pickup. That's it.
See the record yourself
If you ever want to see the temperature record for a shipment you opened, it's available through your distributor on request.

We work with a small number of pharmaceutical distributors and manufacturers at a time. If you move temperature-sensitive medicine and would like to talk about a pilot lane, we'd like to hear from you.
