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 is B2B SaaS lead generation?

B2B SaaS lead generation is the process of finding and qualifying companies that sell subscription software to businesses, then reaching out to them with a relevant offer. It combines data sourcing (finding SaaS companies that match your ICP), outreach (cold email, LinkedIn, ads), and qualification (filtering for fit and timing).

What is the best channel for SaaS lead generation?

Cold email remains the highest-volume, lowest-cost outbound channel for B2B SaaS lead generation. LinkedIn outreach is effective for higher-ACV products. Paid ads (Google, LinkedIn) work well for inbound. The best approach usually combines 2–3 channels.

B2B SaaS Lead Generation — Complete Guide for 2026

The three pillars

1. Data - finding the right companies

The foundation of SaaS lead generation is a clean list of companies that match your ICP. Options:

SaaS-only databases (port587) - every record is a verified SaaS company. Fastest path.
Generic B2B databases (Apollo, ZoomInfo) - broad data, requires heavy filtering.
Manual research (G2, Product Hunt, LinkedIn) - free but doesn't scale.
Enrichment workflows (Clay) - flexible but requires setup.

2. Outreach - reaching decision-makers

Cold email - highest volume, lowest cost. Works well with clean SaaS data.
LinkedIn - effective for higher-ACV, relationship-based selling.
Cold calling - works in some segments, especially with direct dial numbers.
Paid ads (Google, LinkedIn) - generate inbound interest from SaaS buyers searching for solutions.

3. Qualification - filtering for fit

Not every SaaS company is a fit. Qualify based on:

Company stage - are they at the right size/revenue for your product?
Tech stack - do they use tools that signal need for your product?
Hiring signals - are they hiring roles your product serves?
Timing - are they actively looking for a solution?

Port587 free account for small test exports
Cold email via Gmail or free tier sequencer

Growth ($100-$500/mo):

SaaS-only database (port587) for clean data
Sequencing tool (Instantly, Smartlead)
500-2,000 emails/month

Scale ($500+/mo):

Multiple data sources + enrichment (Clay)
Multi-channel outreach (email + LinkedIn + ads)
2,000-10,000+ touches/month

Common mistakes

Bad data - sending to generic B2B lists where only 10-20% are SaaS companies.
No ICP definition - targeting all SaaS instead of a specific segment.
Volume over relevance - sending 50K generic emails instead of 5K personalised ones.
Ignoring deliverability - poor domain setup, high bounce rates, aggressive volume.

The single highest-leverage improvement in SaaS lead generation is upgrading your data source. When every company on your list is actually a SaaS company that matches your ICP, mediocre copy still generates meetings.
