Whatsapp Chatbot production-grade that ships on day one

Build WhatsApp Business API chatbots powered by LLMs — customer support, lead qualification, orders, and more.

Overview

What WhatsApp AI Chatbot Development looks like with us

From scoping call to go-live, our Whatsapp Chatbot engagements are designed for teams that care about what actually ships. Security and privacy are built in: NDA-first, least-privilege IAM, EU or US data residency, VPC-isolated deployment options. Every engagement starts with a mutual NDA, a scoping conversation with a senior engineer, and a written proposal within one week. All work product, source code, and documentation is assigned to you on payment — no vendor lock-in, ever.

FAQs

Common questions

Does it integrate with our CRM or helpdesk?

Yes — Zendesk, Intercom, Salesforce, HubSpot, Freshdesk, and custom systems via webhook.

What containment rates should I expect?

For well-scoped support bots with a clean knowledge base, 40-65% containment is realistic. We baseline on your actual transcripts before quoting numbers.

Do you sign NDAs before a scoping call?

Yes — standard practice. We circulate a mutual NDA before any detailed conversation about your product, data, or roadmap.

What does pricing look like?

Three models: fixed-scope for clear MVPs, monthly retainer for ongoing engineering, or day-rate staff augmentation. We send a written quote within one week of the scoping call.
