Frequently asked questions
What is a B2B SaaS leads database?
A B2B SaaS leads database is a searchable collection of verified software-as-a-service companies with firmographic data, contact information, and technology signals. port587 contains over 240,000 verified B2B SaaS companies that can be filtered by industry, geography, company size, revenue, and funding stage.
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 as CSV or JSON. No forced bundles of sequencing, CRM, or calling features.
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 periodically validated through automated email verification and website enrichment. For the best possible deliverability, we still strongly recommend running your own email validation, warming, and segmentation before sending campaigns.
How much does port587 cost?
Pay-per-lead pricing with no subscriptions. Starter: 10,000 credits for $80 (~$0.008/lead). Growth: 30,000 credits for $200 (~$0.0067/lead). Scale: 100,000+ credits for $600 (~$0.006/lead). Credits never expire, and you only spend them when contact data is available.
Do credits expire?
No. Credits never expire. Buy them once and use them whenever you need to export leads. There are no monthly minimums or use-it-or-lose-it policies.
Can I use the API?
Yes. Create an API key from your dashboard and integrate lead search directly into your tools, workflows, or Clay tables via the REST API.
What formats can I export?
Leads can be exported as CSV or JSON, ready for import into HubSpot, Salesforce, Apollo, Clay, or any CRM and enrichment tool.
What data fields are included?
Up to 15 core firmographic and contact fields per lead, including company name, domain, industry, employee count, revenue range, location, and verified contact data where available.
