Delta: a daily video series across TikTok, Instagram and YouTube

Delta is a health app built by our team. Its marketing runs on two short video series posted daily across TikTok, Instagram and YouTube Shorts.

What RayCMO does

• Posts what was approved. Episodes go out on schedule only after a human approves them. As of 5 November, five videos and two X posts are live and 52 approved posts are scheduled.
• Keeps series in order. When an episode was approved before the ones before it, RayCMO re-slotted the series so episodes post in order on each channel, and shows why a post is waiting.
• Writes in Delta’s voice. The voice was built from Delta’s brand setup and the captions the founders approved: “deadpan friend who reads your bloodwork: one dry joke, one plain fact, never a diagnosis.”
• Makes videos in Delta’s brand. Product demos use Delta’s own colours and fonts, and the 3D mascot series runs on the same pipeline.

What we learned

• Health claims need guardrails: diagnosis, disease claims and guaranteed results are on Delta’s never-say list.
• A visible “waiting because…” reason saved a stuck post that would otherwise have failed silently.

Numbers are from our own RayCMO workspace, as of 2026-11-05.
