An agency built for advertisers who read their own reports.
Casperine exists for one reason: most small advertisers can't tell whether their ad spend is working, because the account is a mess and the reporting is decoration. We fix the account, verify the measurement, and report in language a business owner can use.
What we believe
Structure beats tricks. Clean campaigns, honest tracking, and a weekly testing rhythm outperform clever hacks — and they survive personnel changes, platform updates, and budget swings.
How we engage
Audit first, then management. Fixed-scope audits produce written findings; management follows only if the numbers justify it. You own every account we touch.
What we won't do
No fabricated case studies, no guaranteed ROAS, no locking you into platforms or contracts you can't leave. This site shows only labeled concept work — never implied client results.
Where we work
We're based in Paris, France, and manage accounts remotely across time zones. One accountable manager per account, reachable by email.
