A neutral hub between every buyer and seller of used electronics.
Refurbished phones, laptops and tablets are the fastest-growing segment of European e-commerce — and the least trusted. EST fixes that with a simple model: no device changes hands, and no money moves, until we have physically verified the hardware and confirmed it matches the listing.
The refurb market is built on trust nobody verifies.
Every marketplace tries to solve this alone — with seller reputation systems, AI photo checks, and warranty insurance. None of them open the device. That is why fraud rates keep climbing as volumes grow.
"A-grade", "like new", "excellent" — every platform uses its own scale, and most are filled out by hand. Buyers receive the wrong device 1 in 5 times.
Liquid corrosion, reballed CPUs, jump-wired traces, swapped Face ID modules — none of it shows up in a photo or a 2-minute software test.
Blacklisted, region-locked, or carrier-blocked devices are resold across borders every day. The buyer finds out at activation.
Money is released before the device is verified. Returns burn weeks. Platforms eat the cost or lose the customer.
Keep European electronics in European hands — for longer.
Every device that fails the second-hand market becomes e-waste, or worse, gets shipped out of the EU to be stripped for parts. Enso Systems exists to break that cycle. By making the refurbished market verifiably trustworthy, we extend the working life of millions of devices, recover value for European sellers, and keep critical hardware inside the bloc.
Each verified device gets a Digital Product Passport with full repair, ownership and component history — so its next sale is faster, fairer, and traceable.
Operated from Santo Tirso, Portugal. No US or Chinese cloud dependency in the validation chain. Aligned with EU DPP 2027 and Right to Repair.
Microsoldering-grade inspection by trained technicians, not a checkbox app. We open devices the way criminals do — so buyers never have to.
One integration. Every listing, verifiably real.
Whether you run a C2C marketplace, a B2B refurb auction, a buy-back program or a circular retail brand — EST plugs in as your trust layer. You keep the customer relationship. We handle the part that scares them.
One API call, or a hosted checkout option. Sellers ship to the nearest EST hub instead of the buyer. No platform rebuild required.
Buyer pays at purchase. Money is locked in segregated escrow under EU law. Neither side is exposed during transit and audit.
IMEI clearance, board-level inspection, battery health, component authenticity, software wipe and OS reseal — typically under 48 hours.
On pass, we ship to the buyer with a tamper-evident seal and mint the Digital Product Passport. On fail, the buyer is automatically refunded and the seller gets a forensic report.
The trust infrastructure you'd never build alone.
Setting up a microsoldering lab, escrow licensing, and a DPP minting stack across the EU is a multi-year project. EST gives you all of it as a service — priced per validation, with no minimums during pilot.
