Verified prospect data, on demand.
Prospectuso turns a domain into real, structured contacts — then scores every email for deliverability so you only keep the ones that land. Valid, risky or invalid, on every row.
verified Honest statuses — we return unknown before we ever fake a “valid”.
Enrich the record. Verify the reach.
From a bare domain to a deliverability-scored contact list — with a source and confidence attached to every field, so you can trust what you send to.
Company enrichment
Resolve a domain into firmographics — industry, size band, location and tech signals — normalised and deduplicated.
Contact discovery
Role holders and person contacts with the detected email pattern (e.g. {first}.{last}@) — never invented, always sourced.
Deliverability check
Syntax, MX, catch-all detection and a respectful SMTP probe → valid, risky, invalid or an honest unknown.
API & bulk CSV
Single lookups, bulk lists, or a metered REST API with confidence + source on every field and signed-URL exports.
Domain in, deliverable list out — in three steps
