About Agency Inside
We built Agency Inside to make exceptional digital agency work discoverable, comparable, and learnable.
Agency Inside is the intelligence layer for digital agency work. We structure real case studies by platform, service, and industry so agencies and digital buyers can spot patterns, shortlist better, and move faster.
Why it exists
Great agency work is fragmented across thousands of websites. We organize it into one structured, searchable system.
How it works
Cases are discovered, enriched, and grouped by platform, service, and industry — then amplified! We do that through active outreach and embeds. See tools.
Who it helps
Agencies track peers and visibility. Buyers evaluate real delivery evidence, not polished positioning copy.
Founder note
Built by Sebastiaan van der Lans
After 20+ years in the agency world, Seb built Agency Inside as the platform he always wanted: a place where exceptional work is visible, useful, and easy to learn from.
For founders & builders
How I built this platform with AI — in days, not months
Agency Inside runs on zero AI credits — local models, no SaaS, all self-built with a small team of agents. The practical guide documents the full system: pipeline design, coding agents, content ops, and the memory architecture that keeps everything consistent. € 29.
