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 employee ranges can I filter by?

port587 supports filtering by common ranges like 1–10, 10–50, 50–200, and 200+ employees. These ranges correspond to typical SaaS company stages — from solo founders to scaled teams with dedicated sales and ops departments.

SaaS Leads by Headcount

Why headcount matters for outbound

1-10 employees - solo founders and micro-SaaS. Price-sensitive, fast decisions, founder approves everything.
10-50 employees - past product-market fit. Investing in tools, growing the team, still moving fast.
50-200 employees - scaling. Dedicated roles for marketing, sales, ops. More formal procurement.
200+ employees - established. Multi-team buying centers, longer sales cycles, higher ACVs.

How to use headcount filtering

Export and tailor your messaging to the company's stage.

Headcount is more reliable than revenue estimates for most outbound targeting. It's publicly visible (LinkedIn, job boards) and correlates strongly with buying stage. A SaaS-only database ensures headcount data is accurate for actual SaaS companies.
