Frequently Asked Questions

Can't find the answers to your questions?
Reach out to us by clicking here.

We don’t offer a free trial, but you can start with pay-as-you-go to validate data quality and integration without commitment. If you have a specific use case, we can also share an evaluation plan during a demo.

We specialize in B2B open-source intelligence (OSINT). Reverse Contact collects and structures publicly available information from online sources to build company and people profiles, activity signals, job postings, and related business context — designed for product and workflow integration.

We prioritize precision over coverage. You can choose stricter matching rules, and we return null when we’re not confident — so your product and workflows stay trustworthy.

You can resolve data live on-demand for maximum freshness, or retrieve it from our database for faster access. In all cases, we include “last_updated” metadata so you can make an informed decision based on freshness.

Yes. You can use our API for on-demand resolution, bulk exports for backfills and warehouse pipelines, and webhooks for asynchronous delivery — so you can decouple your workflow from latency and timeouts.

Reverse Contact is built with compliance-by-design principles. We support data subject rights and maintain transparent data practices aligned with GDPR/CCPA expectations.

B2B Data made for Products & Workflows

Stop cleaning and reconciling records. Start shipping products powered by a reliable identity layer.
