Our Story

Building the infrastructure of the domain economy

Sedo was founded in 2001 in Cologne, Germany, with a simple but powerful idea: create a neutral, transparent marketplace where domain owners could connect with buyers from anywhere in the world. At a time when domain trading was fragmented and opaque, we built the platform that changed everything.

Over two decades, Sedo has grown into the world's largest domain marketplace — not just in listing volume, but in the depth of services we offer. From search and instant purchase to broker-assisted negotiations and professional appraisals, we've built an end-to-end platform that serves everyone from individual entrepreneurs to Fortune 500 companies.

As part of United Internet AG, one of Europe's leading internet companies, Sedo combines the agility of a domain-focused specialist with the resources and stability of a major technology group. This structure allows us to invest continuously in infrastructure, technology, and the expertise of our global team.

Today, our platform processes millions of inquiries each year, facilitating transactions that range from a few hundred dollars to multi-million dollar headline sales. Our escrow-backed transfer process and transparent pricing have made Sedo the trusted choice for serious domain transactions worldwide.

Our Mission

What We Stand For

Our principles

Every decision at Sedo is guided by a commitment to transparency, security, and equal access for all market participants.

Radical Transparency

No hidden fees, no opaque pricing. Every listing shows clear price expectations and our commission structure is published openly. What you see is what you pay.

Buyer & Seller Protection

Our escrow-backed transfer process holds funds securely until the domain is successfully transferred. Both parties are protected at every step of every transaction.

Truly Global Reach

With buyers and sellers in 220+ countries and multi-language support, we've removed geographic barriers so the best domain finds the right owner — regardless of borders.

Domain Expertise

Our team of industry veterans brings over two decades of domain market knowledge. Our brokers, appraisers, and account managers are among the most experienced in the business.

Continuous Innovation

From AI-powered valuations to real-time auction technology, we invest heavily in tools that make domain transactions faster, smarter, and more reliable year after year.

Neutral Marketplace

Sedo does not speculatively acquire domains for resale. We are a pure marketplace — our only incentive is helping buyers and sellers find each other at fair value.
