Sirena CRM (Zenvia): alternative and comparison for WhatsApp

What Sirena CRM (Zenvia) is

Sirena, now part of Zenvia, is a platform focused on centralizing sales conversations over WhatsApp and other channels, aimed at sales teams that need to follow up on leads.

What to look for when comparing tools like this

Real multi-agent support: multiple people handling the same number without stepping on each other.
AI automation: not just scheduled messages, but intelligent replies based on the conversation's context.
Total cost: beyond the monthly fee, check for extra costs per number, per agent, or per message.
Ease of setup: how long it takes to get it running without depending on a technical team.

What to consider before choosing

The best tool depends on your team size and how much you want to automate with AI versus just organizing conversations manually. It's worth testing before committing to an annual contract.

HeroChat offers a multi-agent inbox, an AI bot that summarizes and suggests the next action, a product catalog connected to payment, and content tools (Vox) for ads — all in one panel, built for businesses that want to sell over WhatsApp without needing a dedicated technical team.
