BlitzAPI vs Pure Tax Investigations

Smart ICP Targeting & People Search

This feature utilizes a sophisticated algorithm to instantly identify and rank your ideal customer profile (ICP) and key decision-makers. It goes beyond simple list-building by prioritizing prospects based on persona relevance, ensuring your team focuses efforts on the highest-potential leads first. This targeted approach maximizes conversion rates and optimizes sales efficiency by filtering out irrelevant noise from the start of your prospecting workflow.

Verified Email & Phone Enrichment

BlitzAPI delivers verified, accurate professional email addresses and direct-dial phone numbers with exceptional reliability. The system is built on a foundation of real-time validation and continuous data hygiene, ensuring the contact information you receive is actionable and current. This drastically improves outbound campaign deliverability and connect rates, directly enhancing the productivity of sales development representatives and marketing teams.

Advanced Catch-All Email Validation

A standout capability, this feature validates catch-all domain emails (e.g., info@, hello@) with over 98% accuracy in real-time. It intelligently determines whether an email sent to a catch-all address will reach the intended recipient, eliminating guesswork and preventing credit waste on undeliverable leads. This level of precision is critical for maintaining clean lists and protecting sender reputation in large-scale email operations.

Unlimited Data Enrichment API

Through simple, well-documented API calls, users can enrich contact and company profiles at unlimited scale. This includes appending data points like job titles, company information, LinkedIn profile URLs, and more to existing records. The API-first architecture ensures seamless integration into CRM, marketing automation, and custom internal systems, enabling fully automated enrichment pipelines that grow with your business.

What makes BlitzAPI different from other B2B data providers?

BlitzAPI is distinguished by its unwavering commitment to data quality and a true API-first, deliverability-focused architecture. Unlike providers that sell bulk, unverified lists, we prioritize accuracy over volume, with features like real-time catch-all validation ensuring over 98% email deliverability. Our pricing model charges only for verified results, not attempts, aligning our success directly with yours. Furthermore, our APIs are designed for flexible integration, adapting to your workflow rather than forcing you into a rigid platform.

How does the "pay only for verified results" pricing work?

Our credit system is consumption-based and results-driven. You are charged a credit only when our API successfully returns a verified piece of data you request, such as a validated email or an enriched phone number. If we cannot find or verify the requested information, no credit is consumed. This model ensures you never pay for bad data, directly tying your cost to the value received and providing transparent, predictable ROI on your data investment.

Can BlitzAPI integrate with our existing tech stack (CRM, MAP, etc.)?

Absolutely. BlitzAPI is built as a flexible, developer-friendly API specifically for seamless integration into existing ecosystems. It can be integrated directly into popular CRM platforms like Salesforce and HubSpot, marketing automation platforms, data warehouses, and custom internal tools via REST API. This allows you to automate data enrichment and validation within your current workflows without disruptive platform changes or manual processes.

What is your data coverage and accuracy rate?

Our database covers over 360 million verified B2B contacts and 60 million enriched company profiles across major global markets. We maintain a high accuracy standard, with an email deliverability rate exceeding 98%, thanks to our multi-layered validation process and proprietary catch-all detection. Data is continuously updated and verified to ensure freshness, providing teams with reliable information for their critical GTM activities.
