The first stop on your way to online success

Good ideas and great products need the right name, and an internet address which is as easy to remember as possible, but what can you do if the domain you want is already taken?

It was still easy in the pioneer years of the World Wide Web to register suitable names as internet domains, but meanwhile practically all web addresses which promise success are already taken.

As the largest trade platform for “used” domains, we help customers all over the world to find the perfect domain when the preferred domain of choice is already taken.

We bring hundreds of buyers and sellers together every day, and with a market share of 60%, we are the leading provider in what we refer to as the "secondary market" for previously registered domains.


Welcome to the world's largest domain marketplace.

With over 24 million listed domains and 3 million customers, Sedo is the world's largest platform for the professional trading of web addresses.

What started as a "Search Engine for Domain Offers", today Sedo's online shop provides not only a convenient searchable domain marketplace, but also extensive services for domain buyers and sellers: From domain parking to value appraisals all the way up to the brokerage and marketing of domains by our professional brokerage team.

Specially tailored to customers from the internet industry, one of the world's largest distribution networks for domains (SedoMLS) offers extensive registry services which we use to support owners of Top Level Domains (TLDs) with the market launch of their new domain extensions.

Dharmesh Shah, CTO

"We put a lot of thought into posting valuable content for our customers, partners and even employees, so culturecode.com was a natural place to unveil our own culture code.

We also wanted the ability to easily share the code, and giving someone a lengthy URL or asking them to do a search on our site isn’t very convenient.  On the other hand, a custom domain like culturecode.com is much easier to remember.”
