port587

Clay Alternative for SaaS Lead Sourcing

Short answer

Clay builds lead lists through waterfall enrichment - chaining multiple data providers to assemble and enrich records. port587 takes a different approach: a pre-built SaaS-only database you can search, filter, and export from immediately, without designing enrichment workflows.

Clay vs port587

Approach:

  • Clay - build lists from scratch using enrichment workflows. Maximum flexibility, requires setup and data provider credits.
  • port587 - pre-curated SaaS company dataset. Search, filter, export. No workflow design needed.

Best for:

  • Clay - teams that want custom data assembly and have the technical skill to design enrichment workflows.
  • port587 - teams that want clean SaaS data now without building and maintaining data pipelines.

When to use port587 instead of Clay

  • You need SaaS company lists quickly without designing workflows.
  • You don't have the time or desire to manage multiple data provider credits.
  • Your primary need is SaaS-specific company data, not custom enrichment.

When to use Clay

  • You need custom enrichment beyond what any single database provides.
  • You want to combine multiple data sources into a single workflow.
  • You have a technical operator who enjoys building data pipelines.

Using both together

Many teams use port587 as the initial data source and Clay for enrichment on top. Export a clean SaaS company list from port587, then run it through Clay workflows to add custom fields, verify emails, or enrich with technographic data.
