Everything a firm needs to win work

From the first website visit to the new client, in one place.

See who visits your website

Find out which companies are reading your service pages, so you know who to call before they call a rival.

A pipeline from enquiry to signed

Companies, contacts and deals in one view, with every email and meeting saved to the client record.

Meeting booking links

Prospects book a call from a link that knows your diary, with questions asked before the meeting.

Client records in one place

Every client and prospect has one record, with their emails, meetings, deals and consent kept together.

Outreach that stays personal

Email and LinkedIn sequences, each message checked before it sends.

Content and PR that builds trust

Articles, press releases and story ideas from your own expertise, plus a view of how AI search describes you.

Less software, more signed work

Most firms pay for a CRM, a booking link, an outreach tool and a lead tool. mDOS brings them together.

HubSpot and Pipedrive

Sales pipelines and CRMs. You keep the pipeline and drop the extra seats, because mDOS has no per-user fees.

Calendly

Meeting booking links. You save a subscription and every meeting lands on the right client record.

Leadfeeder and Lemlist

Website visitor and outreach tools. You save the fees and stop copying leads between systems.

Switch at your own pace

Start with visitor intelligence or your pipeline and keep your current CRM while its contract runs out. We move your contacts, companies and deal history across and build a tailored switching plan with you. Each step goes live only when your team is trained and ready.

How switching works

Three things no one else brings together

Most firms juggle a CRM, 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.
