About follow.si
The .si marketplace and hub for superintelligence brands.
Last updated 4 November 2026
.si reads as SI: superintelligence. follow.si is where founders find that name. You can check any .si name, buy a premium name from our portfolio, see recent .si sales, and browse the SI and tech startups already building on .si.
What you can do here
- Buy a premium name. Every name under For sale is from our own portfolio. Each has its own page with brand concepts, and checkout runs through Spaceship escrow.
- Follow the market. Sales lists reported .si sales with price, date and platform. Stats shows the registry in numbers.
- See who is building. The Showcase features SI and tech startups live on .si, and launches on recently sold names.
- Find a free name. The finder checks availability and suggests close alternatives.
- Get your page. Sign in to list the .si names you own on your own page at follow.si/yourname.
Who is behind it
follow.si is built and run by Senthil Rajendren through Niaan Ventures. Senthil has invested in domain names since 2009. The names for sale here are our own portfolio, also offered at 99brands.si.
Disclosure: because we sell names, we never present our listings as independent data. Sales, stats and the showcase are built from public sources and our own checks, and our listings do not change how any other name is shown.
Brand concepts
The logos, taglines and product ideas on each listing are concepts created with generative models to help you picture the name in use. They are inspiration only: not trademarks, not registered marks and not part of the sale unless we agree otherwise.
Where the data comes from
New names
New .si names appear in public certificate transparency logs when a certificate is issued for them. We read those logs continuously. A name's "First observed" date is when we first saw it there, which is not always its registration date.
Websites
We check nameservers and homepages on a schedule and record changes. "Live" means a real page answered, not a parked page.
Registry statistics
Registry totals and daily registrations come from the public charts on Register.si, imported daily.
Sales
Sales come from public reports and marketplace data, each credited to its source. "Reported" means a private or unconfirmed sale. A missing record does not mean a sale did not happen.
Availability
The finder checks DNS first, then the registry's public lookup at a polite rate. Results can change at any moment, so the registrar confirms availability at checkout.
What we are not
follow.si is not a registrar and is not affiliated with Register.si, Arnes or any registrar.
