SubRadar: Moderation Intelligence Platform for Indie Hackers
SaaS and app creators struggle to find subreddits that won't instantly delete promotional posts, as traditional metrics like subscriber counts do not accurately predict post survival rates, leading to wasted effort and banned accounts.
Is the problem real?
SaaS and app creators struggle to find subreddits that won't instantly delete promotional posts, as traditional metrics like subscriber counts do not accurately predict post survival rates.
EVIDENCE
6 weeks mapping subreddit removal rates. Community age predicted survival, not size.

Who feels this pain?
TARGET USERS
Solo founders and small app teams trying to find receptive subreddits where their product launch or promotional posts will survive past 48 hours.
Context
Current Workarounds
Where's the gap?
EXISTING SOLUTION GAPS
OPPORTUNITY & VALUE
Repeated explicit complaints about standard marketing advice leading directly to high deletion rates due to vanity metrics, alongside unmonitored discrepancies regarding consumer app vs B2B moderation performance.
Moves away from useless subscriber counts to focus exclusively on historical post survival rates, moderation strictness data, and account age/karma requirements.
A data-driven analytics platform that scores subreddits based on actual post historical survival rates, moderation strictness, community age, and specific content formats (consumer apps vs. dev tools) rather than vanity metrics.
How does it make money?
MONETIZATION
Model
Users are already spending weeks running manual, localized distribution experiments and building complex custom scrapers. A $29 payment easily offsets the high engineering or opportunity cost of burned Reddit accounts and failed distribution campaigns.
How do you ship it?
MVP PLAN
“Find subreddits that actually keep your product launch posts up.”
A data-driven analytics platform that scores subreddits based on actual post historical survival rates, moderation strictness, community age, and specific content formats (consumer apps vs. dev tools) rather than vanity metrics.
Core Features
Weekly Roadmap
- •Build data collection engine to sample posts and track if they remain live after 48 hours
- •Calculate basic moderation friction indices (community age vs post deletion rate)
- •Set up database schema optimizing for rapid subreddit lookups
- •Develop user interface displaying survival probability metrics for SaaS, dev tools, and consumer apps
- •Integrate user account registration and simple search engine parameters
- •Add data markers showcasing required account age and karma thresholds per subreddit
- •Implement Stripe subscription billing logic for the $29/mo plan
- •Onboard 10 active indie hackers from r/SaaS to gather feedback on data accuracy
- •Refine data processing models based on beta tester edge-case observations
- •Publish an open data report titled 'We analyzed 40k posts to find subreddits that don't delete your SaaS'
- •Open registration to the public and track conversions
- •Optimize performance of the data pipeline based on production web traffic
Launch directly on communities where target users hang out, such as r/indiehackers, r/SaaS, and Indie Hackers, using real moderation survival data teardowns as lead magnets.
RISKS & ASSUMPTIONS
Top Risks
Reddit aggressively restricts unauthorized data collection, making continuous tracking of deleted posts difficult without robust infrastructure.
Subreddit moderation teams rotate or change internal rules without notice, which could instantly invalidate historical survival scores.
Founders may subscribe for exactly one month to find their launch targets and immediately cancel until their next product cycle.

Generate an investment memoWhat this score means
This idea scores in the upper-middle range of opportunities surfaced by MonetScope, with a validation sub-score of 8/10 against 3 independently sourced evidence signals. A "promising" rating usually indicates a real pain has been detected and discussed in the open, but the pipeline did not find enough signal to flag it as urgent or high-frequency. These opportunities can still produce excellent businesses — they often correspond to "boring" problems that established players have ignored — but the founder should expect a longer customer-development cycle to confirm willingness to pay.
Why this matters for SaaS founders
It sits at the intersection of "analytics", "distribution", "indie-hackers", which makes it relevant to a specific subset of founders rather than a generic horizontal opportunity. SaaS opportunities at this stage tend to win on the strength of their initial wedge — a single workflow that the target user runs every week, where the existing solution is either spreadsheets, a clunky incumbent feature, or a manual process they hate. The build cost is moderate; the distribution cost is everything. The MonetScope pipeline surfaces this category alongside other saas signals, which is why it appears here rather than in a generic "trending ideas" feed.
Scores are derived from real forum discussions across Reddit, Hacker News and X, weighted by evidence volume and signal quality. How scoring works
Frequently asked questions
Is "SubRadar: Moderation Intelligence Platform for Indie Hackers" a real validated startup idea or just an AI-generated suggestion?
MonetScope does not generate ideas from a language model's imagination. Every opportunity on this site is anchored to specific source posts and comments from real public discussions — typically on Reddit, Hacker News, or X — where actual users describe the pain in their own words. The AI's role is structuring, scoring, and grouping those signals into a navigable opportunity, not inventing the problem.
How recent is the underlying data for analytics?
MonetScope's spider pipeline runs continuously and surfaces opportunities as new evidence accumulates. The "Updated" date in the header reflects the most recent re-scoring of this specific opportunity. Most saas opportunities visible in the public catalog draw from discussions in the last 30-60 days; older signals are de-prioritized because user pain shifts faster than most founders assume.
What's the difference between "overall score" and "validation score"?
Overall score is a composite across six dimensions — pain, urgency, willingness to pay, market size, defensibility, and execution ease — designed to give a single number for triage. Validation score is narrower: it asks "how cleanly does the same signal repeat across independent sources?" An opportunity can score high on overall but lower on validation when one or two large discussions dominate the evidence; conversely, validation can be high on a smaller-overall idea where the signal is consistent but the addressable market is modest.
