We built QuantumSky because buying a used phone shouldn't feel like settling.
Every Android device has untapped potential. We turn that into value — for the multi-store retailers and refurbishers who sell them, and the customers who use them.
More value from every device.
The global pre-install industry has a reputation problem. Too many players use dark patterns, sell data, or sneak past disclosure. We exist to do the opposite — and to prove that honest pre-installs are actually better business.
We partner with device resellers and distributors who want to offer more without taking on more. We build features users actually keep. And we make the whole thing work at scale without compromising either side.
Three things we won't compromise on.
Honest by default
We disclose everything. Users know what's on their device, how it works, and how to remove it. Transparency isn't a policy — it's the product.
Built for both sides
Partners earn real revenue. Users get real features. We don't work if either side loses. Every decision gets tested against that.
Real impact, not greenwashing
We fund actual environmental causes — verified, trackable, certificated. Not carbon credits. Not offsets. Tangible, named projects.
