Founder & CEO, Techtree
Ryan Hannan is the founder and CEO of Techtree. He started the company in 2021 to build the trade-in experience he wished existed: instant quotes, fair prices and no hassle.
As founder, he is responsible for how Techtree grades and prices the devices it buys. Every price on this blog comes from that same price book, the numbers behind Techtree's instant quote, and updates as the book does.
He writes about what devices are worth, how to get one ready to sell, and when selling makes sense.
