AI Sales and Support Agent With a Built-In Customer List for Small Businesses
Argentine startup that began when a weekend AI bot on Instagram and WhatsApp beat the product it was built for.
In plain English
Prometheo answers customer messages for small businesses on WhatsApp, Instagram and the web. Its AI replies to questions, follows up with people who might buy, and keeps track of every customer in one list. The founders discovered the idea when a bot they built in a weekend was more popular than their main product. Businesses pay a monthly subscription.
$620K yearly recurring revenue (company statement to Ámbito, Jan 2026)

Realistic income
The company told the Argentine newspaper Ámbito, reprinted in January 2026, that Prometheo had $620,000 in yearly recurring revenue. This figure is operator-reported, not independently verified. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live source — numbers change.
Risks
- The $620K yearly figure comes from the company’s own statement to the press.
- Messaging platforms have strict rules for automated messages.
- Wrong answers can lose sales.
- Startup cost and time to first dollar are not disclosed.
*Income figures are illustrative ranges based on public pricing and typical outcomes reported by practitioners, not guarantees. Most new online businesses earn little or nothing at first. Not financial, legal or tax advice.
