The .co domain extension has been repurposed to stand for company, community or commerce.
The .co domain is the country code top-level domain (ccTLD) for Colombia, introduced in 1991. While originally intended for local use, it has since become a globally recognized, shorter alternative to .com. Thanks to its universal association with company, corporation, Community and commerce, .co has evolved into a popular generic top-level domain (gTLD)-like option for startups, entrepreneurs, and modern businesses around the world.
The .co namespace was originally managed by Universidad de los Andes until 2009. That same year, after a competitive bidding process, rights were awarded to .CO Internet S.A.S., founded by Juan Diego Calle in Colombia.
In 2014, Neustar acquired .CO Internet S.A.S., and in 2020, GoDaddy Registry took over as the backend provider and registry operator. Today, GoDaddy manages .co alongside other major TLDs like .tv, .club, .design, .us, .biz, and .nyc, while ultimate control of the extension remains with Colombia’s government.
Startup & Tech Appeal: Since its global relaunch in 2010, .co quickly became the “runner-up” to .com, especially in the startup ecosystem. Its adoption was fueled by events, sponsorships, and partnerships with accelerators and entrepreneurial communities.
Short & Memorable: A natural abbreviation for “company,” .co is shorter than .com, making it appealing for modern brands that value brevity.
Global Recognition: Search engines treat .co similarly to .com in global contexts, giving it strong credibility and SEO value.
Brand Alternatives: With many prime .com domains taken, .co serves as a viable backup for businesses that want a clean, recognizable domain.
Marketing Push: Through billboard campaigns in cities like Los Angeles, San Francisco, and New York, media interviews, and grassroots support for entrepreneurs, the .co registry successfully repositioned the domain from “Colombia only” to global business identity.
A pivotal moment came when Juan Diego Calle, co-founder of .CO Internet S.A.S., realized the potential of the extension. A friend reminded him that “co” isn’t just for Colombia — it’s shorthand for “company” all over the world.
This sparked a campaign to turn .co into a global extension. After regulatory hurdles in Colombia, Calle and his team launched the registry in 2010 with the vision of making .co synonymous with startups and innovation.
They backed this up with:
Partnerships with startup accelerators and events.
Offering perks to entrepreneurs who launched businesses on .co.
High-profile marketing campaigns in Silicon Valley, NYC, and Los Angeles.
Ultimately, GoDaddy’s global reach and registrar power were crucial in propelling .co into mainstream adoption.

These examples highlight .co’s strong alignment with tech, startups, and digital-first companies.
Like .com, premium .co domains have fetched six-figure sales, showing that investors and businesses see long-term value:
o.co – Sold to Overstock for $350,000 (2010).
insurance.co – Reportedly sold for $81,000 (2010).
e.co – Auctioned for $81,000 (2010).
onlinecasino.co – Sold for $100,000 (2013).
The .co extension started as Colombia’s ccTLD but has since become a globally recognized, startup-friendly alternative to .com. With its short, memorable form and strong association with “company,” it resonates with modern brands and entrepreneurs. Thanks to Juan Diego Calle’s vision, aggressive marketing, and GoDaddy’s global infrastructure, .co has secured its place as a credible, innovative, and commercially valuable TLD.
