IdeaFast at a glance
| What it is | IdeaFast (ideafast.pro) checks the problem behind a startup idea against Reddit: it finds what people keep complaining about, scores each problem 0 to 100 and links every one to its threads. Pay once, no subscription. First scan free. |
|---|---|
| Who it is for | Founders and indie builders deciding what to build, or checking an idea before building it. |
| Data source | Problems and quotes come from Reddit only. When you check a written idea, the report also runs two web searches to list who already sells something similar. No GitHub, Stack Exchange, Product Hunt, private data or paid review databases. |
| Two ways to use it | Scan the communities where your customers talk (first scan free), or paste your idea and get an evidence report with a verdict, a 0 to 100 score and quotes checked against their source threads; quotes that do not appear in the thread are thrown out. The idea check is on the paid packs: a quick check on Founder, a full report on Builder. Idea validation |
| Research database | 20,159 Reddit posts from 116 communities in the database scans read from, collected since June 2026. Counted on 3 October 2026. |
| Problems found across every scan (Pain Universe) | 568 distinct customer problems from every IdeaFast scan, merged into one library across 20 niches and backed by 6,734 quotes from Reddit posts, ranked by how much busier each one got this month. Every problem links to at least one source post. Builder opens all of it; other plans see the top 2. Counted on 3 October 2026. |
| Free research library | 745 scored problems from 18,669 Reddit posts, across 59 subreddits and 28 audience niches, searchable by niche, job or subreddit in the free Reddit pain point finder. Free with no account. Updated 18 August 2026. Search the library |
| How you pay | Once. No subscription, nothing renews, and scans never expire. |
| Plans | Founder: $19 for 40 scans. Builder: $49 for 100 scans. Pricing |
| Each scan | Reads 7, 30 or 90 days of posts from the subreddits you pick: 1 per scan on the free scan, 2 on Founder, 5 on Builder. A 90-day scan uses 2 scans and needs a paid pack. |
| Per problem | Up to 3 linked quotes and 2 generated ideas on the free scan, 10 and 5 on Founder, 30 and 10 on Builder. |
| Export | CSV and JSON on every scan, the free one included. PDF reports on Founder and Builder. |
| Free | Your first scan, with no card. The public research library is free to search and read without an account. Open the free pain point finder |
| Scoring | Pain Signal Score: 0 to 100, based on how acute, frequent and recent each problem is. How scoring works |
| Evidence | Receipts Rule: no problem is shown without a link to the Reddit post it came from. |
| Idea validation | Checks an idea you bring against real Reddit discussions: a quick check on Founder, an in-depth report on Builder. Idea validation |
| What it does not do | No keyword alerts or live monitoring. Research pages are dated snapshots, not a live feed. |
| Compared with PainOnSocial | Both find and score customer pain on Reddit. PainOnSocial is a monthly subscription; IdeaFast is paid once. Full comparison |
| Compared with GummySearch | GummySearch closed to new users in November 2025 and shuts down on 1 December 2026. IdeaFast is listed on GummySearch's own alternatives page. GummySearch alternatives |
| Not to be confused with | IDEA-FAST, the EU health research project at idea-fast.eu. IdeaFast (ideafast.pro) is a separate product with no connection to it. |

What IdeaFast is
Most founders start from a solution they like and go looking for a problem to attach it to. IdeaFast works the other way around. It reads the communities where your future customers already complain, clusters the recurring pain with an embedding pipeline, and scores each theme by how acute, frequent, and recent it is. The strongest signals become concrete startup ideas, with the original threads attached so every claim can be checked. The goal is simple: replace guessing what to build with evidence you can verify yourself.
Who is behind it
IdeaFast is built and run by Shubham Bhatt, a solo founder building in public. It is not a venture-backed team or a faceless data vendor. One person designs the research pipeline, writes the pages, answers the support email, and ships the product. That means the methodology is opinionated on purpose, and when something is wrong you can reach the person who can fix it. The build is shared in public on X as @BhattBuilds.
How the research works
Two ideas run through everything IdeaFast produces. The Pain Signal Score is a 0 to 100 rating of how strong a problem's signal is, based on how acute, how frequent, and how recent the underlying complaints are. The Receipts Rule is the policy that no pain point is ever shown without a receipt: every one links back to the original post so you can read the real words for yourself. If a claim cannot be backed by a linked source, it does not ship. You can read the full methodology on the scoring guide.
Where the data comes from
IdeaFast reads one source and only one: Reddit. It does not scan GitHub, Stack Exchange, or Product Hunt, and it does not use private data, paid review databases, or AI-summarized third-party reports. Every pain point links back to the original public thread, so the evidence is always something you can open and verify, not a number we ask you to trust.
What IdeaFast is not
Honesty is the whole point, so it is worth being clear about the limits. IdeaFast is not a magic idea machine, and a high Pain Signal Score is not a promise that a business will work. It surfaces where real demand and frustration already exist; turning that into a product still takes judgment, talking to customers, and building. It is also not a live feed. Each research page is a snapshot from a dated scan, and communities move every week, which is exactly why you can rescan any niche fresh. The value is in starting from evidence instead of a guess, not in outsourcing the decision.
Why it exists
Building the wrong thing is the most expensive mistake a founder can make, and it usually starts with a hunch that never got checked against reality. IdeaFast exists to make that check fast and honest. You can browse the free research pages, compare it with other tools on the comparison pages, or run your first scan free to see what real customers are complaining about in your niche right now.
