What they shipped

  • From its YC profile: 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. (source)
  • Its own site describes it as: "tday is the brand-aware design partner that already knows your colors, fonts, and voice. Type the brief, pick the format, ship the post — same hour, every hour." (source)

Who is behind it

  • Cyrus Kelly, Founder/CEO: Co-Founder and CEO of tday. 20 y/o.
