B2B AI WhatsApp Chatbot · Qualify leads and book demos 24/7

A B2B AI WhatsApp chatbot is a conversational agent deployed over the WhatsApp Business API that understands intent with an LLM, qualifies leads with BANT criteria, syncs the conversation with the CRM and books demos in the sales team's calendar. Unlike a decision-tree bot, it reasons over context and adapts the conversation to each lead.

Yes, as long as GDPR and the WhatsApp Business policy are met. The lead must initiate the conversation or accept an explicit and documented opt-in. Messages outside the 24h window require Meta-approved templates. Cronuts deploys the bot with signed DPAs, consent registration and data minimization to the LLM.

Typical implementation at cronuts.digital is 4 weeks: week 1 discovery and conversational design, week 2 technical setup and Meta verification, week 3 end-to-end testing with the sales team and week 4 progressive go-live with daily monitoring. Go-live with bounded scope and continuous iteration during the first 90 days.

Native integration with HubSpot, Salesforce and Pipedrive via API. Each conversation creates or updates a contact, writes custom properties (BANT score, budget, authority, timeline, last intent, transcript URL), generates enriched notes and creates a deal automatically when the score exceeds the threshold. Support for additional CRMs via middleware when the client requires it.

By default we deploy GPT-4o or GPT-4o-mini from OpenAI for classification and responses, and Claude Sonnet 4.5 from Anthropic for cases with more complex reasoning or sensitive data. The stack supports cross-provider fallback for resilience and allows model swapping without redeploying conversational logic.

The agent transfers the conversation to the assigned SDR or AE when it detects a trigger: high BANT score, enterprise intent, complex technical question or explicit lead request. The transfer delivers to the salesperson a 3-line executive summary and the suggested next step. For the lead the transition is invisible: they stay in the same WhatsApp conversation.

The web chatbot lives on a specific page and depends on traffic to that page. The B2B WhatsApp chatbot operates on the channel where your buyers already converse, with 98% open rate, response in minutes and native push notification on the decision-maker's mobile. It also keeps the conversation thread between sessions and allows reactivating dormant leads with approved templates.

The budget depends on scope (number of flows, integrations, languages) and conversation volume. Cronuts works with a fixed implementation fee in 4 weeks and a monthly subscription that covers LLM infrastructure, WhatsApp BSP and continuous iteration. After an initial 30-minute diagnosis we deliver a closed economic proposal.

Conversational dashboard with full funnel: started, qualified, MQL, demo booked, show-up and closed. UTM attribution from the initial click on ads or landing to the closed opportunity in CRM. Main KPIs: qualified leads per month, time to first response, demo booking rate and cost per qualified lead.

40% of B2B forms are filled outside business hours. The chatbot responds 24/7, qualifies, books the demo in the salesperson's available slots and notifies the SDR first thing the next morning with the lead already qualified and the meeting booked.
