Landbase B2B Database

Overview

Landbase B2B Database brings business contact research and list improvement into a single prospecting workflow. It is most compelling for teams that need to find and qualify accounts as well as enrich records they already hold. The breadth is substantial, but teams that depend on a web-app connection to HubSpot or Salesforce should look elsewhere for now.

Its database spans 300M+ verified contacts across 24M+ companies, with 1,500+ enrichment fields per account. Records can include verified emails, direct dials, job titles, firmographics, technology stack, funding history, and hiring activity. Landbase says these details are continually re-checked against live signals and reports 97%+ email deliverability across its database; that rate is a broad vendor claim, not a guarantee for any individual record or campaign.

Founded in 2024 and based in Palo Alto, California, Landbase belongs in the Company Databases category, though its offer extends beyond searching a directory to building and updating audiences.

Key features

Search and audience qualification

Agentic Search lets users describe an ideal customer profile in plain language and returns matching contacts with enrichment fields attached. Advanced filters, technographic data, and intent signals add further ways to narrow results. This combination suits teams with a clear target profile; the database’s size offers reach, while the filters help make that reach more actionable.

For teams starting from their own data, CSV or Excel uploads and CRM connections can be used to match records, append 30+ enrichment fields, and qualify rows. Landbase can also use seed accounts or closed-won lists to identify scored lookalikes across the addressable market. These tools make the product relevant both to prospecting from scratch and to improving an existing audience.

Enrichment and verification

Landbase queries 20+ data providers and validates results through four layers covering email, phone, identity, and catch-all detection. That layered approach, alongside continuous re-checking and the stated 97%+ deliverability rate, is a useful quality signal for teams that need contact data for outreach. It does not remove the need to judge individual records or campaign outcomes.

Tracking, privacy, and security

Web Tracking connects natively with Salesforce, HubSpot, Marketo, and Outreach. Landbase says the tracking feature 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. The demo form says Landbase will reach out within one business day to schedule a demo.

Pricing

Landbase uses a freemium model. The Free plan costs nothing and includes free credits, making it a low-commitment way to begin. The stated plan information does not establish a credit quantity, seat allowance, or renewal term, so the free option is best treated as an initial evaluation rather than a predictable ongoing prospecting allocation.

Paid access starts at $499/mo. That entry point is a significant commitment for smaller teams, and the specific paid-plan limits and inclusions are not given. Custom pricing is offered for tailored requirements. Readers comparing the free and paid options should confirm the credit, seat, and usage terms that apply to their intended workflow before committing.

Platforms

Landbase supports API, Linux, macOS, web, and Windows. Its CLI has installers for macOS and Linux, plus Windows PowerShell. The crucial qualification is that HubSpot and Salesforce CRM connections are currently a CLI capability: the web app cannot connect a CRM yet. Teams that need CRM-linked workflows should account for that difference when choosing between the web interface and CLI.

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 tools to qualify or expand audiences from existing lists. The API and CLI support also make it worth considering for teams that want programmatic or command-line access. It is a weaker choice for buyers who need transparent paid-plan quotas before evaluation, a low-cost paid starting point, or HubSpot and Salesforce connections directly in the web app.

Pros and cons

Pros

Broad coverage across 300M+ contacts and 24M+ companies, with 1,500+ account fields, gives prospecting teams substantial room to target and enrich.

Plain-language ICP search, advanced filters, intent signals, and scored lookalikes support several audience-building approaches.

CSV and Excel matching, enrichment of 30+ fields, and multi-layer validation can serve both list-building and list-cleanup work.

API access and CLI installers for major desktop platforms provide options beyond the web app.

Cons

Paid access starts at $499/mo, a high stated starting point for buyers who only need modest prospecting volume.

HubSpot and Salesforce CRM connections work through the CLI, not the web app, limiting the convenience of browser-centered CRM workflows.

The free plan includes credits, but without a stated quantity it is difficult to assess how much useful evaluation or ongoing work those credits cover.

The 97%+ deliverability figure is database-wide and does not establish the outcome for a particular record or campaign.

Alternatives

Consider Mattermark if its free iOS company-data and news plan or its $49 a month Salesforce Data Enrichment plan better fits your workflow. Wappalyzer is a more targeted option when technology lookups and email verification are the priority; its free plan includes 50 technology lookups per month and 50 email verifications per month.

ZoomInfo is another paid database option, with a permanent free ZoomInfo Lite plan that requires no credit card or commitment. Global Database may suit buyers seeking a lower-cost monthly starting point: its Regis Pro plan is $99 a month, while Regis Free provides five credits per month and CSV/PDF viewing without API access.

PredictLeads is worth considering when API-call usage is the basis for choosing a data provider; its cited tiers are organized around monthly call volumes. PrivCo is an alternative for readers whose needs align with its Researcher plan’s limited profiles, revenue, employee counts, news, and funding-event coverage. BuiltWith focuses on technology lookup, with 10 detailed lookups per day on its free plan and an Advanced plan at $144 a year. Owler offers a free community membership with a sample of sales intelligence and business information.

Verdict

Choose Landbase if your team needs a large B2B database paired with search, enrichment, and audience qualification, and can work with its CLI for HubSpot or Salesforce CRM connections. Its strongest case is the breadth of its data and the range of ways to turn records into a qualified audience. Look elsewhere if you need a lower paid entry point, clear free-credit limits before starting, or CRM connectivity in the web app.
