Sementa

Sementa designs and runs first-party server-side measurement infrastructure for companies whose tracking has outgrown marketing plugins. They take on the whole pipeline: event schemas and dataLayer specs your developers can build against, server-side GTM on Stape, and webhooks that pull offline and later-stage conversions out of your commerce and CRM systems. Consent state gates every event. Your server remembers. A conversion weeks later still finds the click that caused it. Where no usable integration exists, they write the client, tag or variable template themselves. Several are open source, so you can read the code before you hire them. They monitor what they ship.
