Frequently Asked Questions

What is the best free alternative to Lead411?

Landbase offers the best free alternative with unlimited prompt searches and up to 10,000 contact exports per session—no login required. Unlike Lead411's free trial with limited exports, Landbase provides genuinely free access to its full audience discovery capabilities, eliminating potential export fees that can make real costs exceed initial budgets. The platform combines 300M+ contacts with natural-language search and 1,500+ signals for AI-powered qualification.

How does ZoomInfo pricing compare to other sales intelligence platforms?

ZoomInfo represents the premium end of the market with annual contracts and seat-based licensing, contrasting sharply with Landbase's free tier and UpLead's transparent monthly plans starting at $99. ZoomInfo's cost reflects its extensive database and comprehensive feature set, but requires significant budget commitment compared to self-service alternatives. For teams seeking enterprise-grade capabilities without enterprise pricing, Landbase provides an attractive middle ground with free unlimited searches.

Which lead generation tool has the most accurate contact data?

Accuracy standards are converging a significant amount across top platforms, with Cognism's Diamond Data® achieving a high amount of accuracy on phone-verified mobile numbers according to Cognism. Landbase ensures precision through AI qualification using 1,500+ signals rather than relying solely on contact verification, evaluating both contact accuracy and ideal customer fit. The market increasingly prioritizes accuracy over volume, with buyers expecting high verification rates as standard.

Do I need a sales intelligence platform if I already have a CRM?

Yes, CRM systems lack comprehensive prospecting databases and real-time signals needed for effective outbound prospecting. Sales intelligence platforms like Landbase provide the external data and market intelligence needed to build qualified prospect lists, while CRMs manage existing customer relationships. The global sales intelligence market growth from USD 4.40 billion (2024) to USD 10.25 billion (2032) reflects this essential complementary role in modern sales stacks.

What's the difference between intent data and contact data?

Contact data provides basic firmographic and demographic information about companies and individuals, while intent data tracks behavioral signals indicating active buying interest. Intent signals include website visits, content consumption, funding announcements, and job postings that suggest a prospect is in-market. Landbase integrates both through its 1,500+ unique signals, including real-time intent tracking and website visitor intelligence for optimal timing, ensuring you reach prospects when they're most likely to engage.
