Sync Any Source to Every Phone, Automatically
Your organization’s contacts live everywhere: CRMs, HR systems, shared mailboxes, spreadsheets, partner directories, and more. But your teams rely on their phones to reach the people who matter. CiraSync turns scattered, siloed contact data into always‑up‑to‑date contacts on every employee smartphone.
No apps, no user training, no manual updates. This is contact synchronization made simple.
One Unified Goal: Get Every Contact to Every Phone
Whether you need one‑way updates, two-way or full multi‑way synchronization, CiraSync ensures your teams always have accurate, complete contact information at their fingertips.
If it stores contacts, CiraSync can sync it.
You can sync:
- CRMs (Salesforce, HubSpot, Zoho, and more)
- HR systems and employee directories
- Shared mailboxes
- Microsoft 365 Global Address Lists
- Partner and vendor contact lists
- Multi‑tenant or cross‑department directories
- Even CSVs and custom data sources
