Aurora cut creative production from 3 weeks to 2 days.

Aurora is a mindfulness iOS app. Their performance team had been briefing external agencies for hero frames, app-store screenshots, vertical 9:16 cuts, and Meta retargeting variants — a 3-week cycle for every release.

Vertical-first pipeline

Macro generates every Reel, TikTok, and Story in 9:16 by default. Same character, same light, same beat — re-cut to square and 1.91:1 for Meta and the rest of the funnel.

App Store frames generated, not commissioned

Macro generates the hero icon, screenshots, and preview video in Apple's exact spec. No more back-and-forth with the agency on which version is the right size.

Results

• Brief-to-live latency went from 3 weeks to 2 days.
• Cost per install down 38% across iOS and Meta.
• Creative tests per cycle 10×'d — Aurora is now the highest-velocity creative team in their YC batch.
