Company profile

researched Sep 2026

Atom (atomchat.io) is a conversational AI platform built around WhatsApp as a commercial channel. Its "transactional AI" receives inbound leads, identifies intent, qualifies prospects, generates quotes, schedules appointments and follows up end to end, with human sales reps stepping in only when their judgement is needed. The platform also operates by voice, placing and supporting AI-powered WhatsApp calls to answer questions, qualify leads, book appointments and advance opportunities within the same channel.

The product includes an agent inbox with conversation prioritisation (time indicators, advanced filters and combined criteria), automatically generated conversation summaries so reps can resume a chat without reading the full history, and smart suggestions for the next message. An intelligent remarketing module re-engages leads that stopped replying using follow-up messages and calls. Atom connects the advertising, messaging and CRM layers, linking Meta, Google and TikTok ad clicks to WhatsApp conversations and to the eventual close in the CRM, and uses the Conversions API to feed closed sales back into Meta and Google campaigns for optimisation. Integrations span the WhatsApp Business API, HubSpot, Salesforce and more than 100 platforms, with every message, voice note and call logged automatically.

AtomChat also ships a mobile application for iPhone, published by Atomchat Inc, which unifies chats arriving from WhatsApp, Messenger, Instagram, Telegram and other messaging apps into a single inbox and automates responses. The app is available in English, French, Portuguese and Spanish and receives frequent releases covering features such as WhatsApp video calls, HubSpot panel improvements, template messaging and conversation search.

Business model

Atom sells access to its WhatsApp conversational AI platform as a subscription, bundled with implementation and training services delivered by industry specialists who help customers adopt the AI and reach operational autonomy.

Recurring subscription pricing by plan: a Professional plan at USD 1,100 per month including 3 WhatsApp numbers, unlimited users and 5,500 conversations, and a custom-priced Enterprise plan with 5 numbers and more than 20,000 conversations; both tiers include AI components and integrations.

Traction

The company states that more than 400 leading Latin American brands use the platform and cites outcomes including 81% more qualified leads from WhatsApp, 100% of conversations logged in the CRM, recovery of up to 40% of inactive leads and up to 30% lower customer acquisition costs. The iOS app has shipped frequent releases through version 2.8.4 in September 2026.

Latest developments

Recent mobile app releases have added multiselect field support, improved conversation search, WhatsApp video call support, HubSpot panel enhancements and stability fixes; an English-language site and a new web experience at new.atomchat.io are live.
