Frequently Asked Questions (FAQ)
Can AI completely replace my sales development team?

Think of AI as a powerful assistant that handles repetitive tasks while your team focuses on building relationships and closing deals.
What is the difference between AI lead generation and AI lead scoring?
AI lead generation focuses on finding and engaging new potential customers, while AI lead scoring evaluates how likely existing leads are to convert. For example, our AI Meeting Summary tool helps you capture and analyze sales conversations, which can feed into lead scoring systems.
How do I measure the ROI of an AI lead generation tool?
Track these key metrics:
- Cost per qualified lead
- Lead-to-opportunity conversion rate
- Time saved on manual prospecting
- Quality of meetings booked
- Pipeline velocity
What is the best free AI tool to start with?
HubSpot’s AI tools offer the most comprehensive free starting point. You get access to:
