Tucows Registry Takes Over Radix Domains in Strategic Expansion
Tucows just landed a big one.
On August 6, 2025, Tucows Inc. (NASDAQ: TCX), a longtime player in the domain name infrastructure business, announced that it has been chosen by Radix to run technical back-end registry services for its entire portfolio of top-level domains (TLDs). That includes 11 in total—10 generic TLDs and one country-code, plus one second-level domain.
This is a big win for Tucows Registry. The deal brings nearly 10 million domains under its wing, pushing its total portfolio close to 17 million domains worldwide. Tucows will now be responsible for operating the back-end for some of the most widely used domain extensions out there—.online, .store, .tech, .site, and .fun, to name a few.
More Than Just Numbers
Radix isn’t just a domain registry. It’s the biggest portfolio player in the business, with over 10 million domains already on record. Its focus has always been on strings that are memorable, commercially viable, and easy to use across different industries and languages.
The extension .online alone boasts over 3.5 million active registrations—a sign of real traction in the market. Radix’s go-to-market methods have been aggressive, smart, and data-backed, which has paid off in both reach and renewals.
By bringing in Tucows to run its infrastructure, Radix is doubling down on scale. According to Sandeep Ramchandani, Radix’s CEO, the move was about finding a reliable partner that brings proven tech, stable operations, and the ability to support rapid growth. He made it clear this wasn’t a casual switch—it was a decision made to support Radix’s next chapter.
Tucows’ Growing Registry Empire
Tucows Registry has been building momentum since its 2021 acquisition of UNR. That was a turning point. Since then, they’ve taken on domains from the National Internet Exchange of India (NIXI) and now Radix, showing they’re serious about becoming the go-to option for major TLD portfolios.
David Woroch, CEO of Tucows Domains, put it plainly: “This is a milestone.” He also hinted at what’s next—positioning for the ICANN new gTLD round in 2026. That’s the long game here. Tucows is stacking up operational scale now to be ready when new TLDs hit the market.
Why This Deal Matters
This isn’t just about one company swapping out its registry partner. It signals a shift. Big registry operators are consolidating infrastructure with fewer, more capable partners. And Tucows is now firmly at the table with the industry’s biggest players.
By onboarding Radix’s domains, Tucows gets operating leverage and adds heft to its already large reseller ecosystem. That’s significant when you’re supporting over 35,000 web hosts and ISPs around the globe.
The Bigger Picture
Domain names might seem like old news in a digital world chasing blockchain and AI, but don’t be fooled—domain infrastructure is foundational. It’s steady, it scales, and it supports every internet transaction that matters.
Radix has spent the last decade proving that keyword-rich TLDs can perform commercially, not just sit on a shelf. Tucows has spent even longer refining infrastructure that makes those TLDs function reliably at scale.
Together, they’re betting on the next expansion wave, and this deal ensures both have the right pieces in place to compete.
What Happens Next
The full migration of the Radix portfolio to the Tucows platform is scheduled for November 2025. If things go as planned, the transition will bring Tucows Registry’s total count up to nearly 17 million domains under management—making it one of the most significant players in the registry back-end space.
Both companies are clearly preparing for what’s next, and with the 2026 ICANN round looming, this looks like a calculated move to shore up capability ahead of a flood of new TLD applications.
Tucows is no stranger to the domain game. Radix knows how to push high-volume, high-performing TLDs into the market. Now, they’re working in lockstep. It’s a practical alignment with a clear objective: build infrastructure now to support expansion later.
As consolidation continues in the domain registry space, this move may become the blueprint for others looking to scale—without building everything from scratch.
