Social Media/Community Marketer for Mobile App

I’m looking for a social media/community marketer to help grow awareness and attract early users for my mobile app.

The main focus will be organic promotion through relevant online communities and social networks, especially Reddit, as well as other suitable platforms.

The scope includes:

Identify relevant Reddit communities, Facebook groups, forums, and other social channels where our target users are active
Develop a practical organic marketing strategy
Create posts and content that fit naturally within each community
Participate in relevant discussions and introduce the app without appearing spammy
Test different messages, positioning, and content angles
Drive qualified traffic to the app / App Store
Track posts, engagement, traffic, and results
Recommend additional channels or tactics based on performance

I’m not looking for someone who simply posts the same promotional message everywhere. I want someone who understands community marketing, Reddit culture, and how to generate genuine interest and conversations.

Please include in your proposal:

Your experience with Reddit or community marketing
Examples of apps/products you have promoted
How you would approach the first 2–4 weeks
Which channels you would recommend
Your estimated cost
