Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Weak Free-to-Paid Conversion

SaaS and app founders attract free users but cannot convert them into paying customers.

In their words

I installed posthog, saw 100+ recordings but nothing is giving me a clue.

r/SaaS on Reddit

my free tier shows you a number, and the paid tier acts on it. What's worrying is that seeing the number might be most of the value

r/SaaS on Reddit

People taking a free trial and disappearing after.

r/SmallBusinessUAE on Reddit

I've had at least 3 cases in the last month where the student literally says "thank you I will subscribe" at the end and then never hear from them again.

r/Preply on Reddit

Is ~70% cancellation on a 3-day trial normal for hard paywalls, or high? Benchmarks by country would help.

r/AppStoreOptimization on Reddit

I have almost 100 users that don’t pay yet and I feel this hurts Agentys more than it attrack new users.

r/buildinpublic on Reddit

A lot of people sign up simply because they saw a viral video and got curious, but they don't necessarily have a strong intention to pay for the product.

r/startups on Reddit

The number is still around 3–4 per day, and it has not changed for several months.

r/Agentic_SEO on Reddit

when new users 7 day free trial ends and they have to pay, they just stop coming back

r/indianstartups on Reddit

Students love the free features, but the moment we try to monetize even a tiny bit, everyone drops off.

r/StartUpIndia on Reddit

I have around 30 free signups/users from social media promotion but getting to a single paying customer seems very difficult.

r/SaaSMarketing on Reddit

The next challenge is how we make them spend their free credits and purchase more.

Tools they use today

  • Meta Ads
  • App Store Connect
  • Instagram
  • RevenueCat
  • TikTok
  • X
  • Facebook

Why those fall short

  • unknown
  • no retention or paywall data, so they fix the wrong funnel part
  • Users still leave at paywall even with low pricing and autopay enabled
  • paywall sits behind a moment almost nobody reaches
  • Platform offers free trials and encourages students to take them
