What's the minimum contract for bulk datasets?

Do I need engineers to use Coresignal?
For API access, yes—you need technical resources to query, integrate, and process the data. The self-serve Agentic Search tool requires less technical overhead but is still designed for data teams, not end users.
Does Coresignal offer verified contact data for outreach?
No. Coresignal provides business data (company profiles, employee career history, job postings) but not verified emails or phone numbers for direct outreach. Pair with a contact-data tool if direct prospecting is needed.
