We help businesses run on WhatsApp.
SendyStack is the operator-first WhatsApp Business Platform — broadcasts, templates, shared inbox, automations, billing rails, and an in-dashboard AI assistant that actually does the work. One workspace, every channel your customers already use.
Built for global teams.
M-Pesa for East Africa. Stripe Card for everyone else. PayPal as a fallback. Auto-currency, auto-tax — your operators don't notice the difference.

Our mission
Customer conversations belong in the channel customers actually use.
For most of the world, WhatsApp is how people talk to businesses — orders, support, receipts, reminders, follow-ups. Yet most teams still pretend the channel is email first, web-form second, and WhatsApp last.
We built SendyStack so a Property Manager in Nairobi, a Shopify store in Lagos, a SaaS startup in Amsterdam, and a freelancer in São Paulo can all run their customer conversations from one place — with the same template approvals, the same broadcast quality, the same delivery analytics, the same compliance guardrails.
We're here for the operator behind the dashboard, the developer building the integration, and the customer on the other end of the message.
What we value
Four habits we ship every release with.
Trust by default
Compliance with Meta's WhatsApp Business policies is a feature, not an afterthought. Every send goes through automated policy review before it leaves the platform.
Ship the obvious
Most teams don't need another configuration screen — they need the next step done for them. We build for the operator behind the dashboard, not the spec.
Honest pricing
No per-message markup, no setup fees. Plans price the platform — the WhatsApp conversation cost goes directly to Meta at their published rate.
AI in service of humans
Our assistant works in your workspace, not on your data. It calls real tools, scopes to your tenant, and never trains on your conversations.
