EasyCoexistence vs Treble
Treble is a Latin American WhatsApp Business API platform for automated flows, campaigns and AI service, sold through its sales team with no public price. EasyCoexistence connects the number a business already uses in the WhatsApp Business app to Meta's Cloud API through Coexistence, self-serve, at a published US$ 9 per connected number per month.
What happens to the WhatsApp Business app
The two products start from opposite assumptions about the phone.
Treble: Their homepage says Treble is a solution based on WhatsApp Business API, not on the free WhatsApp Business app. It does not mention Coexistence, so ask them whether a number can stay in the app.
EasyCoexistence: The app stays. Coexistence keeps the WhatsApp Business app working on the same number, with about six months of chat history synced, while the Cloud API runs alongside it for automation.
What it costs
One price can be read today. The other needs a conversation.
Treble: No public pricing. The homepage does not show a price and the pricing page asks for a password, so the figure comes from their sales team.
EasyCoexistence: US$ 9 per connected number per month for one to five numbers, falling across six bands to US$ 1 each as you add numbers. Meta bills messaging to the business directly and nothing is marked up.
What each product is
Both are on Meta's official API. They sell different layers.
Treble: A platform for automated chat flows, bulk campaigns and AI customer service, with native HubSpot and Salesforce integrations and an API for custom connections.
EasyCoexistence: The connection and its 24/7 monitoring. Meta delivers webhooks straight to your system, conversation content is never stored on our side, and an MCP server lets AI agents send on the number.
How long until a number is live
Often the deciding question for a small business.
Treble: Through a sales process, since plans and prices are agreed with their team before onboarding.
EasyCoexistence: Usually under two minutes through Meta's Embedded Signup: log in with Facebook, enter the number, scan a QR code in the app. Requirements are app version 2.24.17 or later and recent real activity.
