What data it sees

Do you need an account

No: the server works without sign-in

Find leads, enrich your contacts, and verify emails just by describing what you need. Versium REACH builds and sizes B2B and B2C audiences and fills in the contact and company data you're missing, all in plain language with no manual exports or API code.

What you can do:

  • Build and size audiences: target B2B prospects by industry, company size, revenue, role, and seniority, or consumers by demographics, household income, homeownership, and interests, and preview the estimated size before you build a list.
  • Enrich your records: append business emails, job titles, phone and mobile numbers, mailing addresses, household demographics, and company firmographics to contacts you already have.
  • Verify and resolve: validate email deliverability, find alternate addresses, and identify the company behind a domain or IP.
  • Organize and track: save results to projects, preview list rows, and check a job's status while a list builds.

Example prompts:

  • "How many homeowners in Austin earning over $150k are interested in green energy?"
  • "Enrich these emails with each person's job title, company, and business email."
  • "Build a list of marketing directors at software companies in California."

US data only. Estimates are free; building a list draws on your Versium account credits and always confirms with you first. Requires an active Versium REACH subscription with API access.

create_job Create a B2B or B2C listgen job for the authenticated user. Use `project_id` when possible. For charge-on-finish jobs, tell the user about usage and only submit `usage_consent_confirmed = true` after they consent. Read the `consent_required_job_types` meta field to know which job types require consent.
