Some domain investors build portfolios of a few hundred names. Others reach a few thousand.
Kalin Karakehayov chose a slightly different interpretation of “portfolio.”
The Bulgarian entrepreneur is the founder and CEO of SEO.Domains and Edoms, businesses focused heavily on expired and aged domains, domain acquisition, valuation and SEO value. His own website describes Edoms as operating a portfolio of around 200,000 domain names, while a 2026 interview puts the number at more than 200,000.
From Chess to Domains
Before becoming known in the domain industry, Karakehayov was a competitive chess player and earned the title of International Master. Chess databases record a peak Elo rating above 2500.
The connection is almost too convenient for a domain article: evaluate the position, calculate several moves ahead, manage risk and try not to sacrifice your queen… or, in our case, accidentally let the best domain in the portfolio expire.
Karakehayov moved from SEO deeper into the domain business around 2014, when what became SEO.Domains began concentrating on expired-domain acquisition and dropcatching.
Domains as Infrastructure
What makes Karakehayov particularly interesting is that his approach is somewhat different from the traditional image of a domainer waiting for the perfect end-user sale.
For SEO.Domains, the previous history of a domain, backlinks, authority, geographic relevance and SEO potential can be just as important as the beauty of the name itself. The company says it evaluates expiring names at scale and uses a substantial technical infrastructure and registrar network to catch selected domains immediately after expiration.
This turns domain investing into something closer to an industrial operation.
Thousands of names are analysed.
Some are acquired.
Some are sold.
And somewhere, presumably, there is a renewal invoice capable of frightening an ordinary domainer.
Why Domainers Should Know His Name
Karakehayov is an interesting example because he demonstrates that domain value is not limited to branding.
A domain may have value because it is short.
Because it is memorable.
Because a company desperately wants that exact word.
Or because years of previous use have created an SEO asset that someone else can build upon.
His businesses sit particularly strongly in that last category. SEO.Domains describes itself as a major marketplace for aged domains, while Karakehayov continues to speak publicly about domain acquisition, valuation, SEO and the economics of large portfolios.
For a domainer, perhaps the most interesting lesson is not simply that someone can own 200,000 domains.
It is that a portfolio of that size cannot be managed purely by intuition.
At some point, domain investing becomes data, systems, automation, infrastructure and probability.
Which, coming from an International Master in chess, somehow feels appropriate.
“Even though I’m known as an SEO expert, I now run the domain side of our company.” — Kalin Karakehayov
