Landbase B2B Database

Overview

Landbase brings together a database of 300M+ verified contacts across 24M+ companies and more than 1,500 enrichment fields per account. Records can include emails, direct dials, job titles, firmographic details, technology stack, funding history, and hiring activity. The breadth supports both prospect discovery and research on existing accounts.

Landbase says it continuously rechecks contact and company details using live signals and reports 97%+ email deliverability across its database, with addresses verified before delivery. Those are broad vendor claims, not a guarantee that every address or campaign will perform equally well. Founded in 2024 and headquartered in Palo Alto, California, the company also offers Company Databases capabilities beyond a static directory.

Key features

Search and targeting

Agentic Search takes an ideal customer profile written in plain language and returns matching contacts with enrichment fields attached. Advanced filters, technographic data, and intent signals provide additional ways to narrow results. This combination is useful for teams with a defined target market; it is less compelling if the main need is simply a basic company lookup.

Enrichment and audience building

Users can upload CSV or Excel files, or connect a CRM, to match records, append 30+ enrichment fields, and qualify rows. Landbase queries more than 20 data providers and validates results across email, phone, identity, and catch-all detection. That multi-layer approach makes list improvement a core use, though the CRM connection caveat matters: HubSpot and Salesforce connections currently require the CLI because the web app cannot connect a CRM.

Lookalikes and tracking

Seed accounts or closed-won lists can be used to find scored lookalikes across the addressable market, a practical route to expanding an audience from known wins. Web Tracking connects natively with Salesforce, HubSpot, Marketo, and Outreach. Landbase says its tracking identifies companies rather than individuals and complies with GDPR, CCPA, and major B2B privacy standards. Its terms also describe administrative, physical, and technical safeguards for customer-data security, confidentiality, and integrity.

Pricing

Landbase uses a freemium model. The Free plan costs 0.00 USD per free and offers free credits, making it a low-commitment way to start. The published plan information gives no credit allowance or seat count, so teams should confirm whether the free allocation suits their expected volume before relying on it for sustained prospecting.

Paid access starts at $499/mo. The Custom plan has custom pricing and is described as tailored pricing by contacting Landbase. No seat, quota, renewal, or trial terms are given for these paid options, so the entry point alone does not establish the total cost for a team. Landbase is most straightforward for buyers willing to discuss requirements directly; those seeking a clearly bounded self-serve paid tier may prefer a more transparent option.

Platforms

Landbase supports API, Linux, macOS, web, and Windows. Its CLI has installers for macOS and Linux, plus Windows PowerShell. The platform range is broad, but the CLI requirement for HubSpot and Salesforce CRM connections makes the web app less self-contained for those workflows.

Who it's for

Landbase is a strong fit for sales and marketing teams that need a large B2B contact pool, multiple enrichment signals, and ways to expand audiences from existing lists or closed-won accounts. It is also relevant to teams that can work through a CLI for CRM connections. Organizations that require browser-based HubSpot or Salesforce syncing, or need firm plan quotas before buying, should weigh that friction before choosing it.

Pros and cons

• Pros: The 300M+ contact and 24M+ company database, with more than 1,500 enrichment fields per account, gives prospecting and account research substantial scope.
• Pros: Plain-language ICP search, list enrichment, and scored lookalikes cover several audience-building tasks in one product.
• Pros: The free plan offers credits, so teams can begin without a paid commitment.
• Cons: HubSpot and Salesforce CRM connections are CLI-only, limiting convenience for teams expecting to connect from the web app.
• Cons: Paid access starts at $499/mo, while published seat and usage limits are absent; budget fit is harder to judge in advance.
• Cons: The reported 97%+ deliverability rate is database-wide, not an assurance for an individual record or campaign.

Alternatives

For a technology-focused lookup workflow, Wappalyzer is worth considering: its free tier includes 50 technology lookups and 50 email verifications per month, plus website alerts and sample lead lists. BuiltWith offers 10 detailed lookups per day free, while its Advanced plan costs 144.00 USD per year with a one-year minimum; choose it when that lookup-oriented model better matches the job than Landbase's broader audience-building workflow.

Enigma has free console access for viewing, search, and live summaries, with standard rate limits, making it a possible fit for users who want to start with those capabilities. North Data offers a company-base Data API for 500.00 EUR per month on a 12-month minimum, including 5,000 requests per month; it may suit a buyer seeking a defined company-data API allowance.

OpenCorporates is a paid alternative with an Essentials plan at 2250.00 GBP per year, billed at £ 2,250/year and £225 per month, including API access and up to 500 API calls per month. Consider it when that stated API allowance fits the intended use. Kompass is another freemium company-information option.

Zauba Corp offers a free database of approximately 10,000 companies, a more bounded starting point for buyers whose needs fit that scale. Pappers is a freemium web-based alternative.

Verdict

Landbase is best for teams that want a large B2B contact database tied to search, enrichment, and lookalike audience building. Its most persuasive advantage is the breadth of that combined workflow; its main drawback is the $499/mo paid starting point alongside CLI-only HubSpot and Salesforce connections. Choose it when audience-building depth matters more than web-based CRM convenience, and look elsewhere if that connection path or upfront cost is a deal-breaker.
