Perfect. Please mark finance as the approver.

Contact synced to Attio

BUILT FOR BUSINESSES THAT RUN ON WHATSAPP

Every chat becomes clean CRM context

WhatsApp message lands

A client reply arrives in the channel your team already uses.

Record is matched

WhatSync connects the phone number to the right Attio person.

Context is written

Conversation notes, timestamps, and metadata are saved cleanly.

Next step is visible

Sales, support, and founders can see the actual latest status.

If your business already uses WhatsApp, WhatSync fits right in.

Open source, inspectable, yours to trust.

PRODUCT IS OPEN SOURCE

WhatSync is not a black-box connector. The core WhatsApp to Attio CRM OS is public on GitHub, so users can inspect the project, understand how it works, and build confidence before connecting customer conversations.

Control what gets synced

Choose destinations, phone matching, timezone, sharing mode, and number filters after connecting.

Give managers visibility without micromanaging

Your team can inspect customer activity in Attio without asking for forwards, screenshots, or manual recaps.

BEFORE YOU CLICK CONNECT

WhatsApp Business setup questions

Full setup guide

Does this work with my existing WhatsApp?

The main flow uses Meta's official WhatsApp Business API. You can use a number you control if it is eligible for WhatsApp Business setup. If you want the QR-code flow instead, use the Connect with QR option in the footer.

Do I need Meta verification?

Meta may require business verification or business portfolio access depending on your setup. The setup guide lists the prerequisites before you authorize anything.

Will I lose old chats?

No. Connecting WhatSync does not delete your WhatsApp chats or your existing Attio records. New messages sync after setup; historical imports are handled separately if you need them.

How long does setup take?

If your Meta Business assets and number are ready, setup is usually a few minutes. If Meta asks for verification, that external review can take longer.
