Best TLDs for Startups

The best domain for a startup is a clean .com if you can get one under about $5k — it needs zero explanation to users, investors, or email filters. If the .com is taken or overpriced, .ai is the right pick for AI companies, and .co is the strongest general-purpose fallback (one letter off, reads as 'company').

The startup domain question has one honest answer and several good fallbacks. Here's the ranking, with reasoning — not another neutral table.

1
.com ★★★★★~$10–15/yr
If you can get a clean .com for under ~$5k, do it and stop thinking about domains forever. It's still the only TLD that requires zero explanation to users, investors, and email filters alike.
2
.ai ★★★★★~$70–100/yr (2-yr min at many registrars)
If you're an AI company, .ai IS your category's .com. Priced accordingly, worth it anyway.
3
.co ★★★★★~$25–35/yr
The best general-purpose fallback — one letter from .com, reads as 'company', fully normalized by a decade of startups.
4
.io ★★★★★~$30–60/yr
Still strong for technical products, but you're paying 2010s-cool prices for a signal that peaked. Consider .dev first if you're developer-facing.
5
.so ★★★★★~$50–80/yr
For word-hack names (notion.so). Plan to graduate to the .com if you win — Notion did.

Skip these

.net — reads as 'the .com was taken and we settled'.

.online — renewal-trap economics and zero prestige.

Common questions

What TLD should a startup use in 2026?

Default to .com when an affordable exact-match exists — it's still the only extension that needs no explanation anywhere. If it's taken or five-figure, use .ai for AI-native products or .co as the best general fallback. Avoid .net and cheap 'renewal-trap' TLDs like .online for your primary brand.

Is .io or .co better for a startup?

.co is the broader .com substitute for any startup (commerce, consumer, or general tech); .io signals a technical or developer product specifically. If you're building a dev tool, consider .dev first — it's cheaper than .io and states the audience more clearly.
