SYNC / integrations

What SYNC connects to.

Each connection, what it does and what it does not do. SYNC works on top of what you already run. There is nothing to replace.

A person at iSyncSO checks it first.

SYNC reads public pages about your company, not people; you connect no mailbox, and nothing is sent to anyone but you. It opens on a private page, online for 90 days, deleted when you ask. We write to you about your first look and the beta, no sequence.

Other countries are in testing. A first look works for any company website. Our company data is strongest in the Netherlands; elsewhere it may find fewer examples, and some may be from other countries.
