Lead411

Lead411 is a B2B contact data and prospecting service with direct-dial data, buyer intent data, technographic filters, and API access. A Chrome Extension works while browsing LinkedIn and other company websites, and integrations include Salesforce, HubSpot, Pipedrive, and Outreach.io. Lead411 says contact information is processed with machine learning, human verification, and real-time email validation; it claims 96%+ email deliverability accuracy and a 97% average for optimized verified emails. Direct-dial numbers receive human verification and location matching. The Pilot plan offers 50 free exports during a 7-day trial, while paid plans start at $49 per month. Most plans include unlimited lead searches and exports, though some have monthly or yearly limits; unused exports roll into the next billing cycle. Monthly plans can be canceled at any time, while annual-plan cancellation options require contacting support. Lead411 was founded in 2001 and is headquartered in Boulder, Colorado. It also states that it is a registered data broker under applicable state laws, including Texas law.

Lead411 combines contact data, prospecting features, and integrations with export allowances that vary by plan. The Pilot plan provides 50 exports over seven days, and paid plans start at $49 per month.

Lead411 is a B2B prospecting platform for teams that need contact records, buyer-intent context and ways to send leads into sales systems. It is best suited to sales organizations that use direct-dial calling, CRM workflows or API connections. The free Pilot options lower the barrier to evaluating the data, while export ceilings and annual-contract terms make plan selection important.

Overview

Lead411 has operated in the contact-data business since 2011, with the company founded in 2001 and headquartered in Boulder, Colorado. Its paid service combines prospect search with contact verification, intent signals and workflow integrations. A free Pilot route is useful for a small evaluation; sustained prospecting requires choosing among plans with different export structures.

Key features

Searches can combine direct-dial data, buyer intent and technographic filters. That combination is practical when a sales team wants to prioritize companies by technology use or apparent buying interest rather than work from a broad directory alone.

Lead411 says contact data is checked with machine learning, human verification and real-time email validation. It claims more than 96% email deliverability accuracy and a 97% average for optimized verified emails; these are useful indicators for email-led teams but are not guarantees for every record. Direct dials receive double verification through human review and location matching, a meaningful advantage for callers who need more than email addresses.

The Chrome Extension works while browsing LinkedIn and other company websites, allowing prospecting outside a separate database screen. API access and integrations with Salesforce, HubSpot, Pipedrive, Outreach.io and other platforms can move records into an existing stack. Ignite and Blaze support multiple users, administrator controls and performance tracking, so they make more sense for coordinated teams than for a solo user.

Pricing

Pilot Light costs $0 for a seven-day free trial and includes 50 free exports. It is a short, tightly capped way to inspect the service, not a continuing prospecting allowance.

Pilot is also $0 for seven days and includes 50 free exports, verified emails, direct phone numbers, search, employee and company data, and the Chrome Extension. It is the more useful free starting point for an individual who wants to evaluate both data and browser workflow.

Spark costs $490 per year, billed monthly, and includes 12,000 exports per year, buyer-intent data and a 1,000-export monthly limit. It fits a lighter ongoing program, but the annual allowance and monthly ceiling require volume planning.

Ignite starts at $1,500 per year and includes flexible yearly exports, optional buyer-intent data, API access, verified emails, direct phone numbers and CRM customizations. The 1,000-plus monthly export level and team controls target growing sales groups that need integrations and more headroom than Spark.

Blaze uses custom pricing and includes unlimited yearly exports, optional buyer-intent data, API access, integrations, custom onboarding and advanced features. It is the logical tier for high-volume or operationally complex teams, though buyers must contact Lead411 for a price.

Most plans offer unlimited lead searches and exports, while some listed plans use monthly or yearly limits. Unused exports roll into the next billing cycle. Monthly billing is available for certain plans and can be canceled at any time; annual-plan options require contacting support to cancel. Lead411 describes the trial as risk-free but does not state a separate refund policy.

Platforms

Lead411 is offered through an API and a Chrome Extension. The extension supports LinkedIn and other company sites, while the API and CRM connections suit teams that need data inside Salesforce, HubSpot, Pipedrive, Outreach.io or another sales process.

Who it's for

Choose Lead411 if verified direct dials, intent-led targeting and CRM or API delivery are central to prospecting. Spark suits modest recurring volume; Ignite is better for teams needing customization and multi-user administration; Blaze is aimed at organizations with unlimited-export requirements. It is less compelling for buyers who need only a small number of contacts or who want a fully transparent, nonannual commitment at higher usage.

Pros and cons

• Pros: direct dials receive double verification; intent and technographic filters sharpen targeting; API, extension and CRM integrations support different workflows; unused exports roll over.
• Cons: free access lasts seven days and allows only 50 exports; Spark has both annual and monthly export limits; annual-plan cancellation requires support contact; Blaze pricing is custom.

Alternatives

LinkedIn Sales Navigator is the better choice for teams working primarily in LinkedIn, with Android, iOS and web access and paid Core and Advanced plans that include 50 InMail credits per month.

sales-i fits organizations that prefer an annual subscription ordered through a formal order form and per-user licenses.

Dealfront is worth considering when a browser extension, free trial and defined seat-and-credit packages are more important than Lead411's contact-data structure.

LeadIQ suits teams wanting a freemium API with a 50-credit free tier and a paid plan for growing sales teams.

Salesmotion is an alternative for API users who want a free 100-credit monthly tier with rollover for three months.

ZoomInfo offers a permanent free Lite plan alongside paid professional service options.

Apollo is a freemium alternative with a free annual credit allocation, sequences, API access and one intent topic.

Dealfront's website visitor identification product is the more relevant option when identifying visiting companies, rather than building a broad contact-data workflow, is the priority.

Verdict

Lead411 is a strong fit for sales teams that will actively use verified direct dials, intent and technographic targeting, then connect results to a CRM or API. Its principal reason to look elsewhere is contractual and operational: free exports are small, some plans cap usage, and annual cancellations require support contact.
