Built to make used iPhone inspection easier to trust.
Synapse was created from real resale operations where proof matters after every sale.
It started on the bench.
Synapse began with a simple, repeated problem: a refurbished iPhone can look perfect in photos and still hide a failing speaker, a soft battery, or a camera that never quite focuses. Sellers knew the condition. Buyers had to take their word for it.
The answer was to inspect every device the same way and turn that inspection into something a buyer could verify on their own. Not a report to file away — a certificate to hand over.
Grounded in a working refurb operation.
Synapse grew out of the inspection standards used at Premier Max Tech, where consistent grading and honest condition reporting were a daily requirement, not a marketing line.
That background shaped the product: the 50-point inspection reflects what actually matters when a device is being graded for resale, and the certificate reflects what a buyer actually needs to trust it.
Why certification matters.
Diagnostics tell your team what happened. A certificate lets your buyer verify it. That difference is the whole point of Synapse.
When proof is verifiable, fewer sales hinge on trust alone. Buyers get a clear, non-PII summary of the device — model, iOS version, capacity, pass and fail counts, inspection date, validity, and result — confirmed from a scannable reference with no login.
What Synapse believes
A few convictions that shape how the product works.
Inspection should be measured, not guessed
The 50-point inspection runs on the device itself — display, cameras, speakers, sensors, Face ID, buttons, and connectivity — so a result reflects the hardware, not a hunch.
Proof should outlive the conversation
A sale ends, but the certificate stays. It is server-issued and tamper-evident, so the buyer can verify the result long after the listing closes.
Verification should be simple
Buyers confirm a certificate from a scannable reference with no login. Trust should not require an account.
Teams should grade the same way
One inspection, shared across every technician seat, means consistent grading whether one person or a full bench runs the device.
See it in practice: the certificate and plans and pricing.
