CampaignHQ: Our own production AI SaaS
Cloud-native email and WhatsApp marketing automation.
The story
What CampaignHQ needed, and what we built.
Most software companies don't ship their own product. KUMO wanted to prove the muscle, build a production SaaS we operate ourselves, with paying customers, AWS Partner status, and the credibility of running a real product business alongside client work. CampaignHQ has paying customers across email and WhatsApp campaigns, with AI features built into the platform.
What we delivered
Six areas of production work.
Multi-tenant SaaS isolation
Per-customer data isolation, role-based access, usage-based billing, and per-tenant policy configuration.
AI chatbots & smart inbox
AI handling routine customer interactions, triaging incoming replies, and escalating exceptions to a human queue.
Campaign automation flows
Drag-and-drop journey builder with conditional logic, A/B variants, and send-time optimisation across channels.
Analytics & deliverability
Real-time delivery, bounce, engagement, and conversion dashboards plus deliverability tooling for SES and WhatsApp.
We run it
AWS Partner, listed on G2 and Capterra, with our own DevOps and on-call rotation. Operating our own product changes how we build for others.
