What is a B2B SaaS leads database?

A B2B SaaS leads database is a searchable collection of verified software-as-a-service companies with contact information, firmographic data, and technology signals. port587's database contains over 100,000 verified B2B SaaS companies that can be filtered by industry, geography, company size, revenue, and funding stage.

How much does the port587 leads database cost?

port587 uses pay-per-lead pricing with no subscriptions. Credits start at $49 for 1,000 leads (~$0.049/lead) and go down to ~$0.02/lead at agency volume (50,000+). Credits never expire, and you only pay when you export contact data.

Where does the data come from?

Leads are sourced from publicly available business directories, LinkedIn, and verified B2B data providers. All data is regularly cleaned, deduplicated, and validated through automated email verification and website enrichment.

How is port587 different from Apollo or ZoomInfo?

port587 is a pure data layer, not an all-in-one platform. You pay only for the leads you export (no seat-based subscriptions), use your own outbound tools, and own your data in CSV or JSON format. Unlike Apollo and ZoomInfo, there are no forced bundles of sequencing, CRM, or calling features.

No. Credits never expire. You buy them once and use them whenever you need to export leads.

Yes. You can create an API key from your dashboard and integrate lead search directly into your tools and workflows via the REST API.

What formats can I export?

Leads can be exported as CSV or JSON, ready for import into any CRM, enrichment tool, or spreadsheet.

What are the best lead generation tools for SaaS?

For SaaS-focused outbound, the best stack typically includes a SaaS-specific database (port587), a sequencing tool (Instantly or Smartlead), and optionally an enrichment layer (Clay or Clearbit). The right tools depend on whether you need broad data, SaaS-specific data, or full-stack automation.

Is Apollo the best lead generation tool?

Apollo is the best all-in-one platform for teams that sell to many industries. For SaaS-only outbound, a dedicated SaaS database (like port587) paired with a sequencer often delivers better data quality at lower cost.

How much do B2B lead generation tools cost?

Prices range from free tiers (Apollo, Lusha) to $15K+/year (ZoomInfo). port587 has no monthly fee — you pay $0.10 per lead exported. Most teams spend $50–$500/month on lead generation tools depending on volume and stack complexity.
