Independent, no seller bias — vehicle analysis

Buying a used car is one of the most expensive single purchases an ordinary consumer makes in Turkey. Yet buyers lack the tools to verify what the seller tells them — dealer reviews are biased, professional inspections are expensive, and listing descriptions are deliberately incomplete.

Bunayorumum was founded in 2024 by an independent solo developer based in Turkey to close this gap. The idea: an automatic assistant that, given a listing URL, explains brand/engine-specific known issues, the market price comparison and damage/paint inconsistencies in plain language. Today the platform runs that assistant on car and motorcycle listings from Sahibinden.com and Arabam.com, alongside a live market price comparison.

Being informed about what you buy is a right that belongs to everyone, from the most knowledgeable to the least.

We all feel the same thing when we buy something: the other side knows something we don't. The seller understands what they're selling far better than you do, and most of the time you have no choice but to take their word for it. And the bigger the purchase, the heavier that uncertainty gets: on the very things people spend the most on, the things they save up for years to afford, reaching the truth is often hardest of all. That imbalance never sat right with us. No one should feel this powerless over a decision they put their own money and effort into. What we do comes down to a single sentence: taking information out of the seller's hands and putting it into the buyer's. We take what's tangled, scattered and often left half-told on purpose, and turn it into something plain, honest and easy to understand. Our job isn't to decide for you; it's to stand beside you, on your side, while you decide.

We started with used cars and motorcycles, but our dream was never bound to them. What we believe is far bigger: none of the important decisions in a person's life should be made in the dark, on nothing but someone else's word. Where we stand today in cars and motorcycles, we want to stand tomorrow in homes, in phones, in computers, in everything people work hard to afford. Personal spending grows a little more every day, and as it grows, reaching the truth stops being a luxury and becomes a right. Our dream is a plain one: a world where everyone, from the most seasoned to the greenest, truly knows what they're buying, where the truth is clear, open and belongs to all. We are building both today and tomorrow on that belief.

There's no big company behind Bunayorumum; there's one independent developer, based in Turkey, who built this alone and runs it the same way. Every line of code, every product decision and all the day-to-day work happens right here, in one pair of hands. It might sound small, but we see it as a promise rather than a weakness: there's no middleman and no department standing between you and us.

The payoff of that closeness is speed. When we hear about a problem, we don't need three meetings first; more often than not we're on it the same day. For anything on your mind, we aim to get back to you within 24 hours on weekdays, because we want you to know there's someone on the other end who genuinely cares about this.
