About lithos
The World's Stone Knowledge, Discoverable
We're building the definitive platform for natural stone — because the most extraordinary building material on earth deserves better than a PDF catalog.
Our Story
Born from
the quarries.
lithos was born from a simple frustration: the natural stone industry, one of the oldest and most beautiful material trades in the world, is nearly impossible to navigate.

Generations in the industry
Information is scattered across supplier catalogs, trade publications, and the minds of a few experts. There's no single place to search, compare, and specify stone with confidence.
We grew up in the quarries of Anatolia.
Our founder, Derin, grew up in the stone trade through ANS Mermer — a Turkish natural stone company with deep roots in the quarries and workshops of Anatolia. Years of watching architects struggle to find the right stone, designers settle for whatever their local yard happened to stock, and projects suffer from preventable specification errors made one thing clear: the industry needed a new kind of resource.
The Mission
Not another catalog. Not another marketplace. A knowledge platform — one that treats stone with the depth it deserves, makes expertise accessible to everyone, and connects the global supply chain in a way that benefits designers and suppliers alike.
Every stone, every quarry, every supplier — searchable and actionable.
We're starting with Turkish stone — travertine, marble, limestone — because that's where our roots are and where we know the material best. But the vision is global: a searchable, visual, data-rich encyclopedia; an AI-powered advisor; a directory of trusted suppliers; and a consulting practice for hands-on guidance.
The Team
Three generations of stone
ANS Mermer has operated in Turkey's stone heartland for three generations — from quarry to finished product. That heritage informs everything we build at lithos: the data we structure, the recommendations we make, and the standards we hold ourselves to. We believe that technology should amplify craft, not replace it.
