Decay

✦ Concept

A social platform where all content automatically deletes after exactly 7 days, but users can 'preserve' one post per month by community vote. The catch: preserved posts become permanently public and searchable forever, creating a tension between ephemerality and legacy.

Target

Gen Z and young millennials (18-28) who are simultaneously addicted to social media and anxious about their digital footprint

Revenue

Premium 'Vault' subscriptions ($9/month) allow users to save drafts privately before posting, plus sponsored 'preservation campaigns' where brands pay $50k to guarantee community preservation of their content

💡 Why It Works

"The permanent social media generation is experiencing 'digital regret fatigue' — they want to share authentically but fear future consequences. Forced ephemerality with rare permanence creates scarcity psychology that makes each post more intentional and valuable."

Startup Starter Guide

First Steps

Build MVP with 7-day auto-delete and basic voting mechanism using React + Firebase

Launch with 100 college students at 3 universities with strict 7-day deletion enforcement

Add community voting for preservation after hitting 1000 active users

Simple MVP

Instagram clone with automatic deletion timer and simple upvote system for preservation voting. Built with React Native + Firebase for auto-deletion scheduling.

Growth Ops

↗ Partner with universities during mental health awareness weeks around 'digital wellness'

↗ Create 'Decay Archives' — public museums of preserved posts that become cultural time capsules

Creative Twist

"The app trains users to think in 'digital mortality' — every post is dying, making sharing feel more human and less performative. Preservation becomes a form of community-granted immortality."
