AI-powered messaging
for non-profits

MessageStack 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.

SMS WhatsApp Web chat Voice

When connectivity fails, SMS still works. We make it intelligent.

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.

  • Works on any phone. No smartphone, no app, no data connection needed.
  • AI-powered responses. Understands natural language questions in multiple languages.
  • Locally relevant. Shelters, water, medical aid, safety information for the affected area.
  • Deploys in hours. Spins up when a crisis hits, not weeks later.

One platform for every conversation your organisation needs

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.

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 now

Fundraising and donations

Conversational donation journeys via SMS and WhatsApp. Event follow-ups, regular giving prompts, and gift aid collection through natural conversation.

On the roadmap

Supporter care

Handle common supporter queries, update contact preferences, share impact stories, and keep your community engaged without overwhelming your team.

On the roadmap

Beneficiary services

Provide the people you serve with instant access to information, appointment reminders, signposting to local services, and ongoing support via messaging.

On the roadmap

Campaigns and events

Targeted messaging for awareness campaigns, event coordination, volunteer mobilisation, and post-event engagement across SMS, WhatsApp, and web.

On the roadmap

Internal comms and helpdesk

Staff and volunteer coordination, shift management, internal Q&A, and knowledge sharing through the same platform your external comms run on.

On the roadmap

Built for non-profits from the ground up

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.

Multi-channel

SMS, WhatsApp, web chat, and voice from a single platform. Meet people on whatever channel they have.

AI that stays on topic

Conversational AI grounded in your organisation's knowledge base. No hallucinations, no off-topic responses.

Works at the edges

Designed for low-connectivity environments. SMS-first architecture that degrades gracefully when data isn't available.

Non-profit pricing

We're not going to charge you enterprise SaaS rates. Pricing that reflects the sector you're in and the work you do.

Built by engineers who've delivered critical services at scale

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.

We're building in the open.

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.
