Overview

tday automatically turns a software company's product into on-brand marketing creative. Connect your product and git repo, and tday generates polished launch videos, social graphics, and ads, the content a team would normally spend hours making in a design tool or pay a freelancer for. tday then publishes the creative and measures how it performs across your social and ad channels, closing the loop from what you ship to what you post.
