The problem

Your agency is leaking revenue

Most agencies lose 30-50% of potential revenue to broken processes. Sound familiar?

Leads fall through the cracks

Spreadsheets, inboxes, and sticky notes are not a CRM. Leads go cold while you figure out who owns them.

Manual follow-up wastes hours

Your team spends more time copying, pasting, and scheduling than actually selling.

No visibility into pipeline

You can't forecast revenue because you don't know what stage your deals are in — or if they're still alive.

The solution

One platform. Every tool you need.

Replace your stack of disconnected tools with a single, purpose-built operating system for client acquisition.

Lead Capture

Forms, landing pages, and webhooks that feed directly into your pipeline. No more copy-paste.

Smart Pipeline

Drag-and-drop deal stages with auto-scoring. Know exactly where every opportunity stands.

Automation Engine

Email, SMS, and WhatsApp sequences triggered by actions. Follow up while you sleep.

Campaign Tracking

Meta and Google Ads integration with cost-per-lead, ROAS, and ROI calculated in real time.

Client Portal

White-label dashboards your clients log into. Show them results without the messy spreadsheet.

Appointment Booking

Calendar sync, automatic reminders, and no-show tracking. Fill your calendar, not your voicemail.

Testimonials

Agencies love ClientOS

We replaced four different tools with ClientOS. Our close rate went from 12% to 27% in the first three months. The automation engine alone saves us 15 hours a week.

Markus Stein

Founder, Stein Digital GmbH

The white-label client portal is a game-changer. Our clients finally see the value we deliver, and churn dropped by 40%. Worth every cent of the Agency plan.

KB

Katharina Bauer

CEO, BauerMedia Agentur

Before ClientOS, we were losing leads because nobody followed up fast enough. Now the automation handles the first three touches and we just close. Revenue is up 60% year over year.
