An AI voice agent makes calls, asks standardized questions about budget, timelines, technical requirements, and decision-making roles, and updates the CRM in real-time. This automates B2B lead qualification, reduces response times, and delivers only warm leads to sales, already prioritized for commercial follow-up. ### How long does it take to implement and integrate with HubSpot? A typical project takes four weeks: strategic setup, script customization, training and testing, then go-live in batches. HubSpot voice agent integration is native: properties are mapped from day one and synchronized automatically, avoiding spreadsheets, errors, and duplications. KPI monitoring takes place directly in HubSpot, in real-time. ### What data does it collect and how does it feed the CRM? The agent collects budget, timelines, use cases, technical requirements, and the contact's role, along with the outcome of each attempt. The data populates predefined HubSpot properties, enabling reporting, scoring, and workflows. This makes inbound lead management in the industrial sector measurable, comparable, and actionable, with immediate handoff to sales and no manual activity. ### What does it cost compared to an internal team and how does it scale? The operational cost is **€0.50/min** of conversation. Unlike fixed internal resources, the model scales with volume: you pay for usage and maintain consistent quality thanks to scripts and automations. For industrial B2B, the ROI comes from reduced times, better data, and more qualified opportunities for the same media budget. ### How do you manage GDPR and consent during calls? Compliance is addressed with clear disclosures and, where necessary, explicit consent. Audio recordings are not used; the system works with text transcripts and interaction logs. Data is minimized, tracked, and stored securely, with controlled CRM integration. All in line with best practices for B2B lead qualification automation. ### What results can I expect in manufacturing inbound lead management? Similar companies report a reduction in processing times of over **70%**, full lead coverage with up to **5** attempts per contact, structured data at the first touchpoint, and **100%** CRM integration. The most evident impact is operational: sales concentrates time on qualified leads, improving conversion rates and pipeline velocity.
