Use the parts you need today. Add the rest when your current contracts end.
Members, volunteers and supporters in one place, with history, preferences and marketing consent on every record.
Membership plans with benefits, card payments and renewal reminders, so fewer members lapse.
Sell tickets for dinners, talks and fundraisers on your own website, with a waitlist when they sell out.
Newsletters, appeals and welcome journeys, sent only to people who have said yes.
Reports and documents written with your real figures, ready for trustees and supporters.
News, events and campaign pages updated by your team, with forms that feed straight into your records.
Most organisations juggle a spreadsheet, a ticketing site and an email tool. mDOS brings them together.
Email priced by list size. With mDOS you pay one monthly price and every email is saved to the supporter’s record.
Ticketing that keeps your attendees’ details. With mDOS you sell on your own website and keep every attendee.
Member lists in a spreadsheet or a separate renewals tool. You save the time spent matching them up.
YOUR AI TEAM, FOR CHARITIES
It works around the clock once you switch it on, and nothing goes out without your approval. It learns your cause, events and tone, and every message is checked against your own records first. Our experts steer it with you. Approve its work from your phone in the mDOS Manager appAwaiting App Store Approval.

Keep your CRM and website. mDOS adds the outreach, ads and reporting, and keeps your records in step.

Most organisations juggle membership software, a marketing agency and AI tools that don’t talk to each other. With mDOS you get The Platform, The AI Agents and The Marketing Experts, working as one team.

One record per supporter, memberships and renewals, events and ticketing, email campaigns and impact reports.

AI agents draft your campaigns and renewal reminders, and spot supporters who have gone quiet. Nothing goes out without your approval.
