Everyday AI
for the next billion.
Hello Castor is the AI assistant that telecoms and super apps distribute and bill to their customers, in their language and at their price.
AI went global.
Paying for it didn't.
Priced in dollars
Premium assistants are priced at around $20/month, built for US wallets.
Designed in English
Spanish is often an afterthought, and so are local needs.
Sold through app stores and credit cards
That leaves out millions of people who pay for everything through their phone bill or wallet app.
Areas to scale. Sources: DataReportal 2026; Stanford AI Index 2026; OpenAI (50M paid consumer subscriptions, Feb 2026); gradually.ai global estimate.
The next billion won't download an AI app.
They'll find it in apps they already pay with.
They own the customer
Carriers and super apps are on every home screen, with millions of verified customers.
They own the billing
AI gets added to a postpaid plan or a wallet in one tap, in local currency, with no card.
They need new revenue
Operators are moving “from selling connectivity to selling digital cognitive capabilities.”
Areas to scale. Telecom figures from the operator's 2Q26 report (40.9M wireless, 12.3M postpaid). A payments app in Mexico adds 3M+ users.
