Although the platform offers a free plan, if you want details about paid plans, you need to contact the sales team. Even their AI chatbot provides little help—it simply repeats that pricing is "tailored based on your business needs," without sharing real estimates.

• Paid plans typically start at ~$60,000 per year
• Growth and Enterprise tiers often exceed $100,000–$300,000 annually, depending on company size, user seats, features, and intent data access

Both free and paid plans use a credit-based system for data searches and exports, and credits do not roll over from month to month.
