See the whole person, keep the list clean and find the right people.
The whole customer on one screen
Visits at every site, spend, preferences and consent, before they walk in.
- Bookings, stays, orders and till sales together
- Dietary needs, occasions and notes
- Marketing consent with where and when it was given
Included with customer records
Everything you know about a customer, in one place.
One profile per customer
Bookings, stays, orders, till sales, loyalty and events all join the same record. No more five versions of the same person in five systems.
Duplicates merged
Find and merge duplicate records, with a full audit trail of what was combined and by whom. Your counts and reports stay honest.
Preferences that matter
Dietary needs, likes, occasions and your own custom fields, ready for your team before every visit.
Segments in plain English
Build audiences from spend, visits, behaviour and custom fields. Describe the group you want in plain English and get a draft segment to check and save.
Consent you can prove
Marketing consent is recorded with where and when it was given. Erase or anonymise a customer everywhere when they ask.
Easy imports
Bring in lists from spreadsheets with duplicates checked, lists cleaned and consent captured as they arrive.

Make it yours. Let it do the legwork.
Work three ways: do it yourself, ask your AI teammate, or let them draft it and take over. A draft lands as a normal item you can edit, not a block of text to copy and paste.

Your fields and segments
Add your own questions, tags and fields, and build segments that update themselves as customers change.

One customer, linked up
Email, phone, Wi-Fi device and card payment are linked to one customer automatically, and duplicates are merged.

Co-Pilot drafts it, you take over
Do it yourself: build a segment rule by rule.
Ask Co-Pilot: Co-Pilot builds the segment from a plain-English request.
Or take over the draft: it lands as a draft segment with a live count, saved as a normal segment in one click.

What it replaces
Customer lists scattered across your booking system, your email tool and your till.
Separate CRMs
SevenRooms CRM and HubSpot keep their own copy of your customers, which drifts out of date the day you set it up. Here every booking, order and sale already lands on one record, with nothing to sync.
Email-tool audiences
Mailchimp and Klaviyo audiences go stale the moment you export them, and their pricing grows with your list. Your segments update themselves from real visits and spend.
Manual GDPR work
Finding someone in every system to delete them can take hours and is easy to get wrong. Here erasure reaches every record in one go, and data-retention rules tidy up old records for you.
YOUR AI TEAM, ON CUSTOMERS
It keeps your customer list healthy
Switch it on and it works around the clock. Nothing goes out without your approval.
Segment drafts
Turns a plain-English description, such as "regulars who haven’t visited since summer", into a draft segment for you to check, adjust and save.
List health review
Checks which groups of customers have stopped opening your emails, so you can win them back with a better offer or give them a rest before they unsubscribe.
Consent records audit
Checks recently added contacts have a clear record of how and when they agreed to hear from you, and flags any that don’t before they’re emailed.
Set up by real people, supported by AI. Our team brings your customer lists together from your old systems and cleans them with you, and the AI team keeps them healthy and well-segmented once you switch it on.
Switch at your own pace
Keep your current CRM or email tool while its contract runs out. We bring your customers, their history and their consent records across, merge the duplicates, and agree a switching plan that keeps your marketing running. It’s phased, never all or nothing.
Three things no one else brings together
Customer records are only as good as what you do with them. mDOS adds AI agents that keep the list healthy and marketers who put it to work.

World-leading software
One profile per customer with bookings, orders, spend, preferences and consent together, shared by every part of mDOS.

Tireless AI agents
AI agents turn a plain-English description into a draft segment, check which groups have stopped opening your emails and flag contacts without clear consent.

Our team brings your lists together from your old systems and cleans them with you, and partner marketers plan the campaigns that bring customers back.
Keep the tools that work for you. Replace the ones that don't.
