Crisis and disaster response
AI-powered information delivered via SMS when infrastructure fails. Shelter locations, medical aid, water, safety updates. Any phone, any language.
Building nowMessageStack is a conversational AI messaging platform built for charities and humanitarian organisations. From disaster relief to fundraising, supporter care to beneficiary services, one platform for every conversation that matters.
Disaster relief
3.4 billion people have no mobile internet. When disaster strikes, that number grows as infrastructure collapses. WhatsApp, apps, and websites all go dark.
MessageStack's disaster relief capability delivers AI-powered, contextual information to affected people via SMS. Any phone, any network, zero data required.

09:15Beyond disaster relief
Disaster relief is where we started. But the same AI messaging infrastructure works across the full range of non-profit communications. We're building MessageStack to handle all of it.
AI-powered information delivered via SMS when infrastructure fails. Shelter locations, medical aid, water, safety updates. Any phone, any language.
Building nowConversational donation journeys via SMS and WhatsApp. Event follow-ups, regular giving prompts, and gift aid collection through natural conversation.
On the roadmapHandle common supporter queries, update contact preferences, share impact stories, and keep your community engaged without overwhelming your team.
On the roadmapProvide the people you serve with instant access to information, appointment reminders, signposting to local services, and ongoing support via messaging.
On the roadmapTargeted messaging for awareness campaigns, event coordination, volunteer mobilisation, and post-event engagement across SMS, WhatsApp, and web.
On the roadmapStaff and volunteer coordination, shift management, internal Q&A, and knowledge sharing through the same platform your external comms run on.
On the roadmapThe platform
Most messaging platforms are built for e-commerce or enterprise sales teams, then awkwardly repurposed for the charity sector. MessageStack is different. We're building specifically for non-profit use cases, budgets, and constraints.
SMS, WhatsApp, web chat, and voice from a single platform. Meet people on whatever channel they have.
Conversational AI grounded in your organisation's knowledge base. No hallucinations, no off-topic responses.
Designed for low-connectivity environments. SMS-first architecture that degrades gracefully when data isn't available.
We're not going to charge you enterprise SaaS rates. Pricing that reflects the sector you're in and the work you do.
About
MessageStack is founded by engineers with experience delivering NHS COVID Pass, Cabinet Office digital programmes, and large-scale charity platforms serving millions. We understand what it takes to build technology that works under pressure, for the people who depend on it.
We believe the non-profit sector deserves the same quality of technology that commercial companies take for granted, built around the problems that actually matter.
If you're a charity, humanitarian organisation, or non-profit that wants better messaging, we'd love to hear from you. Early partners get to shape the product.
