B2B sales teams face a critical bottleneck: responding to inbound leads fast enough. Studies show that calling a lead within 5 minutes increases conversion rates by 400%, yet most companies respond in hours or days. Human SDRs cost €4,000–6,000/month and can only make 50–80 calls per day during business hours.

CPI Technologies saw an opportunity to build an AI-native solution that could call leads within seconds of form submission, qualify them through natural conversation, and book appointments — all without human intervention.

We built PowerSetter.AI as a full-stack Next.js application combining cutting-edge voice AI technologies: speech-to-text with 95%+ accuracy (even with dialects and background noise), LLMs for contextual conversation analysis, and natural voice synthesis with sub-500ms response latency.

The platform integrates natively with HubSpot via OAuth 2.0 for bidirectional CRM sync, Google Calendar and Microsoft Exchange for real-time appointment booking, and supports webhook/API triggers for any external system. A smart follow-up system automatically retries at optimized times respecting recipient timezones.

PowerSetter.AI launched as a self-service SaaS with a freemium pricing model. Users report 3x more appointments compared to manual calling, with an 85% reach rate. Over 90% of call recipients don't realize they're speaking with AI.

The platform reduces lead response time from hours to under 3 seconds and cuts cost-per-contact from €8–15 (human SDR) to €0.50–2. Available 24/7 with multi-language support in German and English, PowerSetter.AI handles the entire journey from lead intake to booked appointment autonomously.
