How Postpone App Mined Reddit Data via API for High-Value Leads

Postpone App, an all-in-one scheduling platform for content creators, grew to over $500k in annual revenue by focusing on a simple marketing strategy.

The founder targeted active Reddit users likely to need his product — without hype or complex tactics.

The Data Collection Process

1. Data Collection: The Reddit API pulled millions of public posts, saved as JSON files.

2. User Identification: Posts were grouped by author. A script ranked the top 5,000 Redditors who posted most frequently. The logic: frequent posters often need tools to manage their online activity.

3. Outreach: A cold DM script invited these users to try Postpone for free. Messages were direct, unpolished, and focused on solving a clear pain point.

The strategy was moderately successful. Reddit’s API provided raw data to pinpoint users who were already invested in the platform. However, Reddit has since restricted free access to its API, making it a paid service for larger companies like Google and OpenAI, which use it for training large language models (LLMs). While this limits access to Reddit data through official channels, alternative sources, such as the dark web, still host terabytes of this data.

Instead of casting a wide net, Postpone focused on a specific group of users who were most likely to find value in the product. By targeting those who posted regularly, Postpone reached people with a visible need for scheduling help. The outreach avoided sales pitches, instead offering a free solution to a problem these users likely faced.

Growth often hinges on identifying where your audience already spends time. Postpone’s approach—using public data to focus on high-potential users—shows how simplicity and precision can drive results without large budgets or aggressive tactics.

TikTok ban is going to be enforced in 90 days. You can still grow in that time period using TikTok. The TikTok algorithm is unmatched.

You can get influencer reach without being an influencer. No other algorithm allows that as easily as TikTok.

Long form copy > Short form copy

People who actually have pain will read a lot. Think about the thing you want the most. You're probably reading and watching about it a lot more than 1 or 2 hours.

AI Sales Agents don't work and have insane churn right now.

But when the underlying models improve in 3 to 6 months, this might be the best business to be in.

Their only move is to not be bankrupt by that time. Whoever can hold onto it until then... will be insanely rich.
