4–6 Hours → Zero: Client Intelligence Platform for a B2B Marketing Agency
The Challenge
A German B2B marketing agency managing around 50 active client accounts had a visibility problem. Critical signals about client health — churn risk, upsell opportunities, emerging frustration — were buried across Slack threads, meeting transcripts, HubSpot emails, and Airtable records.
Preparing for a single quarterly business review required 4–6 hours of manual context gathering per client. With 50 accounts, this meant the team was constantly flying blind or spending vast amounts of time just assembling the picture.
What We Built
60x built a client intelligence platform that ingests data from all four sources, scores sentiment, flags risks, and generates bi-weekly intelligence reports per client — delivered straight to Slack.
During initial rollout, the system correctly identified churn risk for a client before they actually churned. The platform grew to 15 daily active users within months and became the backbone of the agency's entire internal intelligence strategy.
The Results
- QBR preparation: from 4–6 hours of manual context gathering to fully automated intelligence reports
- Total infrastructure cost: approximately €150/month
- LLM costs: under €20/week
- First prototype: delivered in 6 days
The Compounding Effect
The agency hired 60x to build a client intelligence tool — automated sentiment reports delivered to Slack. The first prototype shipped in six days. Within three months, the platform had evolved far beyond its original scope.
The internal team extended the foundation into a company-wide intelligence layer — adding Google Calendar integration, personalised daily digests for every team member, risk heartbeat monitoring, automated case study generation, a meeting prep feature, and performance marketing dashboards.
By early 2026, the platform had 15 daily active users and a company-wide rollout planned. What started as a single scoped project is now the backbone of how the agency runs its entire client services operation — built on top of the architecture 60x delivered in under two weeks.
