IdeaFast
Find startup ideas from real Reddit and Hacker News pain, scored by evidence.
Tagline
Build from real pain, not guesses.
Evidence-backed startup ideas from public complaints.
Stop doomscrolling. Find problems people actually pay to fix.
Public pain, scored and sorted for founders.
Category-defining: The evidence-based startup idea engine for founders.
The page is not selling generic research; it is explicitly about turning public complaints into scored pain themes and startup ideas. That makes it stronger to frame as a decision engine for what to build, not just a search tool.
Alternative-to: The faster, verifiable alternative to doomscrolling Reddit for ideas.
The landing page directly contrasts itself with manual scrolling and open-tab chaos. This angle works because the product’s real differentiator is clustering, scoring, and linking back to sources instead of leaving users to do the synthesis themselves.
Pain-killer: Stop building on polite feedback; build from public complaints with receipts.
The strongest emotional hook on the page is distrust of friend feedback and fear of wasting months on the wrong build. The product’s evidence links, quoted posts, and thin-signal warning directly address that anxiety.
Primary user
Solo or early-stage SaaS founder deciding what to build next
ICP #1
First-time solo founder with a product idea but no existing customer base
Pain
They waste weeks chasing ideas based on vibes, peer feedback, or their own assumptions, then discover too late that nobody is urgently asking for the product.
Why this solves
IdeaFast gives them public proof of pain, ranked by score and backed by quotes, so they can choose a problem with visible demand instead of building blind.
ICP #2
Indie hacker shipping a side project in the next 30 days
Pain
They need a narrow, monetizable pain fast, but don’t want to spend hours reading Reddit threads and manually deduping complaints.
Why this solves
The product compresses community research into a searchable scan with scored themes, letting them move from raw complaints to a buildable idea in minutes.
ICP #3
Agency founder or serial builder doing market research for multiple client concepts
Pain
They need repeatable, exportable evidence to justify direction and avoid pitching ideas that are too weak to sell or build.
Why this solves
The Builder tier’s wider scans, more evidence quotes, PDF export, and full validation give them a process they can reuse across projects.
Strengths
- +The core promise is sharp and emotionally resonant: stop guessing, use real pain signals.
- +It shows a believable product mechanic with a real sample scan, score, and linked quotes instead of abstract claims.
- +Pricing is simple and clearly laddered for different builder types, from Explorer to Builder.
Weaknesses
- −The homepage is too long and repetitive; it says the same thing in several sections without adding new proof.
- −The ICP is still too broad on-page: founders, agencies, serial builders, and anyone with ideas all get the same pitch.
- −The product feels closer to a research utility than a must-have workflow, so the landing page underplays urgency and outcomes.
- −There is almost no quantified proof of accuracy, speed, or conversion impact beyond one sample score.
- −The sample output is interesting, but it doesn’t show the full end-to-end experience of turning a scan into a decision.
Fix these
- Tighten the homepage around one primary ICP: early-stage SaaS founders deciding what to build next.
- Add before-and-after proof: hours saved, number of ideas rejected, or examples of validated themes that led to shipped products.
- Show more of the workflow UI, especially the validation score, saved ideas, and export/report outputs.
- Replace some of the philosophical copy with concrete user outcomes and use cases, like 'pick your next feature,' 'find a niche SaaS wedge,' or 'validate a B2B pain.'
- Add a comparison section versus manual Reddit research and tools like GummySearch so buyers understand why this is different.

Headline
Find startup ideas from real pain
Scan public complaints, score the signal, and build from evidence.
Find problems people repeat
IdeaFast scans Reddit, Hacker News, Stack Exchange, GitHub Issues, and Product Hunt for recurring complaints. Instead of one-off opinions, you get clusters of pain that show up again and again.
Know what is worth chasing
Each theme gets a 0–100 score so you can see which pains have real signal and which ones are too thin. That helps you skip weak ideas before they waste your time.
See the receipts
Every theme links back to the original quotes and posts. You can click through, read the context, and decide for yourself whether the pain is strong enough to build around.
Turn research into a decision
Save scans, export CSV or JSON, and generate validation reports on higher plans. Use it to reject bad ideas faster or back a wedge with evidence.
FAQ
Who is IdeaFast for?
Solo founders, indie hackers, and early-stage SaaS builders who need to pick a problem before they write code. It’s also useful for agencies and operators doing repeatable market research.
How is this different from manually browsing Reddit?
Manual browsing is slow and noisy. IdeaFast clusters repeated complaints, scores the signal, and links the evidence so you can make a decision in minutes instead of getting lost in tabs.
What does the score actually mean?
The score is a rough signal indicator from 0 to 100. Higher scores mean the pain appears more often and looks more consistent; lower scores mean the signal is thin and should be treated carefully.
Can I search by niche or competitor?
Yes. You can scan by subreddit, topic, competitor, or profession to narrow the research to the market you care about.
Can I export the results?
Yes. You can save scans, view history, and export CSV or JSON. Higher plans also include validation and PDF report export.
Most startup ideas are built blind. IdeaFast scans Reddit, HN, Stack Exchange, GitHub Issues, and Product Hunt for real complaints. It clusters the pain, scores it 0–100, and links every theme to the source. Stop guessing what to build.
Reddit is full of startup ideas. The problem is nobody wants to read 500 comments and manually dedupe the same complaint 20 times. IdeaFast does that for you. It turns public pain into scored themes with receipts.
I built this to avoid bad ideas. Too many founders start with vibes, then spend 3 months discovering the market doesn’t care. IdeaFast is the shortcut I wanted: scan public complaints, rank signal, export proof, decide faster.
We kept seeing the same complaint. Founders don’t need more inspiration. They need evidence that a pain exists, repeats, and is strong enough to build around. That’s what IdeaFast surfaces: recurring pain, scored, sourced, and ready to validate.
Friend feedback is usually useless. Public complaints are better. IdeaFast finds them across Reddit, HN, Stack Exchange, GitHub Issues, and PH — then shows you the exact quotes behind each pain theme.
Weeks wasted on fake demand hurt. You build, launch, and only then learn nobody had the problem. IdeaFast helps you spot thin signal early so you can skip the dead-end ideas.
Here’s what a real scan shows: - recurring pain themes - 0–100 score - clickable source quotes - thin-signal warnings - startup ideas derived from the strongest patterns It’s not a list of links. It’s a decision tool.
30 seconds to a better idea. Pick a subreddit, topic, competitor, or profession. IdeaFast scans the public web, clusters the complaints, and tells you which pain is real enough to chase.
Founders keep using it to reject ideas. That’s the real value. A good scan doesn’t just say “here’s an opportunity.” It says “don’t waste your next 6 weeks on this one.”
The best founders want receipts. Not hot takes. Not generic trend charts. They want public quotes, repeated complaints, and a clear signal score before they commit to building.
Angle: evidence-based startup selection
Most founders don’t have an idea problem. They have an evidence problem. They pick something because it sounds smart, feels interesting, or got a few polite nods from friends. Then they spend weeks building before they realize nobody is urgently asking for it. That’s why I built IdeaFast. It scans public conversations across Reddit, Hacker News, Stack Exchange, GitHub Issues, and Product Hunt. Then it clusters recurring complaints into pain themes, scores each one, and links back to the exact source quotes. So instead of starting with a hunch, you start with public proof of pain. The goal is simple: help founders find problems worth building for faster, with less guessing. If you’re deciding what to build next, the question isn’t “What sounds cool?” It’s “What problem shows up again and again, from real people, in public?”
Angle: manual research replacement
I kept seeing founders do the same thing: 1. Open 17 Reddit tabs. 2. Scroll for an hour. 3. Screenshot a few complaints. 4. Forget half of them. 5. Build on vibes anyway. That workflow is broken. Manual research is slow, noisy, and easy to fool yourself with. You end up remembering the loudest comment, not the strongest signal. IdeaFast was built to replace that mess. You can search by subreddit, topic, competitor, or profession. It scans public discussions, groups repeated pain into themes, and shows you the evidence behind each one. It also tells you when signal is thin. That matters more than people think. Sometimes the best output from research is not “build this.” It’s “this looks interesting, but it’s not strong enough yet.” That saves time, energy, and bad bets. If you’re an early-stage founder, that’s the whole game.
Angle: targeted for early-stage founders
I’m tightening the message around one group: solo and early-stage SaaS founders deciding what to build next. Not everyone needs the same kind of research. Agencies want exports. PMs want adjacent opportunities. Builders want inspiration. But the sharpest use case is still the same: find a real pain, verify it exists, and decide whether it deserves your time. IdeaFast does that by scanning public discussions and turning them into scored pain themes with quotes attached. You can save scans, export CSV or JSON, and on higher plans generate validation PDFs. What I like about this category is that it cuts through the nonsense. No trend-chasing. No “AI for everything.” No fake certainty. Just public complaints, organized well enough to make a better decision. If you’ve ever burned weeks on an idea that never had enough demand, you already know why this matters.

Find startup ideas from real pain
Description
Scan Reddit, HN, and more for repeated complaints, score the signal, and turn public pain into startup ideas with source quotes.
Maker's first comment
I built IdeaFast because I got tired of the same founder trap: picking ideas from vibes, then discovering too late that the problem wasn’t strong enough. I wanted a faster way to find real pain before writing code, so I started scanning public discussions where people complain in plain English. IdeaFast pulls recurring complaints from Reddit, Hacker News, Stack Exchange, GitHub Issues, and Product Hunt, then clusters them into themes and scores each one. Every theme links back to the original quotes so you can judge the signal yourself instead of trusting a black box. What I’m most interested in hearing is whether the pain scoring is actually useful in a real decision flow. If you try it, I’d love feedback on the quality of the themes, the clarity of the evidence, and whether it helps you reject weak ideas faster.
Pinned maker comment
I’m especially looking for feedback on the pain scoring, the evidence quotes, and whether the scan output helps you decide what not to build.
Meta
Targeting solo founders choosing their next idea
Hypothesis: solo founders will click if the ad shows a faster way to find real pain than scrolling Reddit for hours. IdeaFast scans public complaints, clusters them into scored themes, and links the source quotes so you can validate before building.
Google Search
startup idea validation from public complaints
Hypothesis: people searching for startup ideas, customer pain, or Reddit validation want evidence, not inspiration. IdeaFast scans Reddit, HN, Stack Exchange, GitHub Issues, and Product Hunt to surface recurring pain themes with source quotes and scores.
Reddit Promoted
Building something nobody asked for?
Hypothesis: indie hackers and first-time founders in Reddit communities want a way to find repeat pain quickly without manual tab chaos. IdeaFast turns public complaints into scored themes with receipts so you can decide what to build next.
Subreddits

Post a teardown of a narrow SaaS idea found from repeated complaints in one niche.
Rules: Keep it specific and actionable. Avoid generic startup marketing.
r/EntrepreneurRideAlong
Share the journey of validating your next idea with real pain signals instead of gut feel.
Rules: Story-first posts work best. Don’t just drop a link.
r/startups
Offer a concrete method for reducing idea risk using public discussion clustering and evidence scoring.
Rules: High bar for promotion. Focus on insight, not product features.
Communities
Post one build log, one teardown, and one case study of a scan turning complaints into a decision. Comment on other founders’ idea-validation threads with useful examples.
Share a tight walkthrough of how you validate a niche before building. Keep it founder-ops focused, not promotional.
