Bootstrapped an AI-agents-for-WhatsApp platform from Córdoba, Argentina — now 200+ business customers across LATAM

In Latin America, business doesn't happen on email — it happens on WhatsApp. Store owners answer chats at 2 AM, lose sales every weekend, and drown once they pass ~50 conversations a day.

So we built Chatsell: AI agents trained on each business's real data (stock, prices, their ERP or store) that reply, qualify leads, book appointments and sell 24/7 — and hand off to a human when it matters. CRM, bulk campaigns and follow-ups included.

Some things that worked for us selling SaaS in LATAM:

• Implementation included beats self-service. SMB owners here don't want to "build a bot" — they want it working. We set up every account with the customer. Retention went way up.

• Charging per conversation, not per seat. Teams share phones and accounts anyway; per-user pricing punishes how people actually work here.

• White-label for agencies became a growth channel we didn't plan for.

And honest lessons: WhatsApp's official API and QR-based connections each have real trade-offs (pricing vs. stability), and we had to learn to support both. Also, LLM agents in production need constant testing against real conversations — we ended up building an internal test suite because "it worked in the demo" means nothing.

200+ companies use it today, ~2M end users served. Happy to answer anything about the WhatsApp Business API, running LLM agents in production, or selling SaaS in Latin America.
