What makes BlitzAPI different from other data providers?

BlitzAPI is architected from the ground up as an API-first infrastructure product, not a legacy sales intelligence platform. We prioritize quality over quantity, offering a "pay-for-results" model where you're only charged for verified, accurate data. Our focus on deliverability, especially with advanced catch-all validation, and seamless integration flexibility means we adapt to your workflow, not the other way around.

How accurate is the email and phone data?

We maintain a >98% email deliverability rate, which is industry-leading. This is achieved through multi-layered verification processes, real-time validation, and our proprietary technology for accurately identifying valid inboxes within catch-all domains. Phone numbers are sourced and verified as direct-dial lines to increase connection rates.

Can I integrate BlitzAPI with my existing tech stack?

Absolutely. BlitzAPI is built for integration. We provide clean, well-documented REST APIs that can be easily connected to any modern CRM (like Salesforce, HubSpot), marketing automation platforms, data warehouses, or custom internal tools. The API-first design ensures you can automate data flows precisely where you need them in your unique GTM workflow.

What is the "Waterfall ICP" approach?

Our Waterfall ICP feature allows you to define a prioritized list of target personas (e.g., "VP of Sales first, then Director of Sales Ops"). BlitzAPI's search will then intelligently find and return contacts in that exact order of priority, stopping once your desired quota is met. This automates the process of targeting the most valuable prospects first, ensuring optimal use of your credits and sales efforts.

BlitzAPI operates on a flexible, usage-based credit system designed to scale with your needs. You only pay for successful, verified results, not for searches or attempts. This ensures maximum cost-efficiency and aligns our success with yours. New users can start immediately with a free trial offering 1,000 credits to test the power and accuracy of the APIs. For custom volume requirements and enterprise plans, you can book a demo to discuss tailored pricing that fits your specific workflow and scale ambitions.
