The companies · Software
Software we build.
Two products: mainstreet gravity runs a whole local media business on one platform, and greetform, which began inside it, turned out useful far beyond local media, so it stands on its own too.

Smart questions and matched offers, right after someone signs up. Built into mainstreet gravity. Free on its own.

One platform · Agent-native

How we operate
People decide. AI agents do the work.
8th Replay is AI-first. People set direction and judge quality. A team of AI agents does the digital execution: writing, editing, building and monitoring. The human team is small by design.
