.io vs .com vs .ai — the 2026 founder's guide to picking a TLD
Every founder argues about this. .com is still the default. .io is the developer's choice. .ai is the new credibility flex. Here's how to decide based on your stage, audience, and budget.
.com — still the trust baseline
73% of the world's top 1M sites use .com. Customers will reflexively try yourbrand.com first. If a non-tech audience is buying from you, just get the .com — even if you have to pay $5k on the aftermarket.
.io — the developer-first signal
Originally a British Indian Ocean Territory ccTLD, .io became the dev-tools default after GitHub Pages and Stripe popularised it. Pros: short, available, cheap (~$35/yr). Cons: weaker with non-technical audiences; ICANN may eventually retire the TLD (long shot, but it's been discussed).
.ai — the new AI-startup flex
Anguilla's ccTLD has become a brand signal for AI-first products. Adoption: up 38% YoY among YC AI startups. Pros: instantly communicates the category. Cons: expensive ($55-99/yr), and increasingly crowded — the name has to be brandable to pop.
Investor perception
Series A+ investors: don't care which TLD, they look at growth. Seed investors: slight bias toward .com (legitimacy signal). Hackathon judges and accelerator partners: .ai or .io is fine if the product fits.
Our recommendation by stage
Pre-product: get the cheapest brandable .com or .ai you can find. Product-market fit reached: upgrade to the matching .com if you don't have it — it's the single highest-ROI brand move for a B2C SaaS.
