1900film is a data-driven advertising agency based in Tokyo, Japan, managing client accounts across Google Ads, Meta, and Yahoo. Their core strength is server-side tracking infrastructure built on Stape — they achieve an average EMQ score of 9 by leveraging Stape Store (reStore) to enrich first-party data and deliver high-quality signals back to Meta via CAPI. This approach has resulted in up to a 200% improvement in CPA for their Meta advertising clients.

They have also developed "track-19DD," a proprietary affiliate measurement platform built natively on Stape's sGTM infrastructure.
