Your Questions, Answered

Clarity, Precision, and Trust—All in One Place

Precision prospecting starts with clarity. This FAQ answers key questions about our human-led process, 99% data accuracy, and crafting ICP-tailored prospect lists. Learn how we verify emails/phones, safeguard exclusivity, or tackle niche needs like catch-all removal and direct-dial sourcing. Unanswered? Reach out—we’ll turn complexity into confidence. 💬

Deep Dive Avenue is a human-verified B2B data research platform specializing in manual, one-to-one prospect research, lead list building, lead enrichment, and pre-qualified lead sourcing. Unlike typical lead data providers, we go beyond generic databases to deliver highly targeted, relevant, and customized prospect lists tailored to each client’s unique needs and specifications.

Never! Deep Dive Avenue never scrapes or exports data from pre-made databases. With the client’s consent, we manually collect and verify information from multiple reliable sources based on data availability. We then align the client’s Ideal Customer Profile (ICP) with key factors like company products, services, job titles, revenue, and employee size—ensuring precise, high-quality data that meets their exact needs.

At Deep Dive Avenue, we specialize in creating highly customized prospect profiles based on very specific data attributes, such as sub-industry sectors, micro-niches, and precise geographical locations (e.g., country-specific, city, state, or radius-based targeting). Unlike automation tools or ready-made databases, we take a manual, deep-dive approach to gather and verify this data, ensuring it aligns perfectly with your unique criteria.

Our research process includes advanced techniques like X-Ray Search, Boolean Search, social media mining, and other specialized methods to uncover these hard-to-find leads. We are committed to delivering highly accurate, tailored prospect profiles that match your exact needs, even when such data isn’t readily available from standard sources.

We manually gather each data point and verify it through a rigorous 3-step human verification process, ensuring 99% accuracy. We cross-check information with reliable sources, and if you find any inaccuracies, we’ll promptly correct them.

While no single email verification tool guarantees 100% accuracy, we use a rigorous three-step process with industry-leading tools to ensure at least 95% email validity, including catch-all addresses. Since 1 in 10 organizations use catch-all emails, we offer a specialized removal service for an additional fee.

We are committed to high-quality data. If you receive bounced emails or inaccurate leads, notify us—we’ll promptly replace them with new, verified leads that align with your Ideal Customer Profile (ICP). Our thorough verification process ensures optimal deliverability.

At Deep Dive Avenue, our basic service includes verified company contact numbers such as headquarters, branch offices, or switchboard lines. For clients seeking direct access to decision-makers, our specialized service delivers rigorously verified direct phone and cell numbers using a blend of deep-dive manual research, web/mobile tools, API integrations, and strategic verification methods. This ensures an 80–85% accuracy rate for direct and mobile numbers. If any number is flagged as invalid post-delivery, we replace it at no extra cost. Designed for sales teams prioritizing direct outreach to key stakeholders, this premium service eliminates gatekeepers and accelerates connections

Absolutely. We specialize in uncovering complex prospect profiles, including email addresses and phone numbers, even when this information is hidden on company websites or unavailable in other lead vendors’ databases or LinkedIn. Our techniques include X-Ray Search, Boolean Search, Google Search, Document Search, Pattern Discovery, Social Media Search, Personal Websites, Journals, and Article Search, ensuring comprehensive results where automated tools often fall short.

Every prospect database we create is unique and exclusive to each client. We customize these databases based on your specific requirements, ensuring that your data is never shared with anyone else. We don’t engage third-party agencies or use your database for any other purposes. Rest assured, your data is completely safe and exclusive to you.

Our pre-qualified leads are ideal prospects with a high likelihood of conversion, ensuring that your outreach focuses on those most likely to engage. We carefully research and source leads using a combination of online research, sales qualification frameworks, B2B buyer journey insights, trigger signals, social media intent data, and sales insights. This approach helps us identify prospects who are actively interested in your products or services—now and in the future. Contact us today to learn more about how we can build a tailored, high-quality lead database for your business.
