# B2C App Idea Filter

> A nine-question checklist for validating consumer app ideas before building

This framework helps indie hackers and solo developers vet consumer app ideas quickly before spending months on development. It focuses on identifying pre-existing demand, market size, and rapid buildability. Running an idea through these nine questions weeds out concepts that lack organic audience interest or viable ad channels.

## The framework

My $100k/mo app idea filter:

1. Are people selling courses?
2. Are there niche specific influencers?
3. Are there more than 10 million people?
4. Can it be built in 7–14 days?
5. Are there communities (Reddit, FB groups)?
6. Are there at least 2 competitors?
7. Are competitors running ads?
8. Can you explain it in a 10-second hook?
9. Does it align with your own interest?

## What it is for

- Vet consumer software concepts prior to writing code
- Identify existing monetization and ad spend in a target niche
- Assess whether an MVP can be launched within two weeks

## Key points

- Checks for market demand via existing course sales and paid ads
- Audits audience size and community concentration across Reddit and Facebook
- Evaluates distribution viability via niche influencers and a 10-second hook
- Limits scope to concepts buildable within 7 to 14 days
- Ensures alignment with personal interest to maintain founder momentum
