Startup ideas and business ideas, sourced from real problems.

A living index of high-demand problems a business should solve — across SaaS, everyday business, and content.

Browse recurring pain points people already complain about, search workarounds for, or pay to solve — organized into three groups below: software problems, everyday business problems, and content gaps. A live section further down pulls in trending discussions so the list keeps reflecting what people are talking about right now.

The score on each card is AI-calculated based on how many discussions mention this problem, how painful it is, and how underserved existing solutions are — not a live pull from a keyword-volume tool. Pair it with Google Trends or a keyword tool before committing to anything.

Browse the categories

Scan the live section and the three categories below — SaaS, business, and content — to find problems that match your skills or interests.

Open a card

Tap any entry to see why it matters, who feels it most, and what a first version might address.

Go validate it

Talk to a few people who match "who feels it" before building anything — the FAQ below has a starting checklist.

SaaS & Software Problems

Software gaps founders and product teams describe repeatedly — the kind of problem that's specific enough to build a focused tool around.

Everyday Business Problems

Operational friction in local and small businesses — scheduling, inventory, payments, and other day-to-day problems that rarely get solved well by generic tools.

Content & Niche Site Ideas

Gaps in existing content — searches that turn up thin, outdated, or generic results, leaving room for something genuinely useful.

No problems extracted yet.

The AI is reading discussions and pulling out problems — this usually takes a few seconds. If nothing shows up, the API may be temporarily rate-limited.

How this list gets made

Field Index pulls problems from real discussions — Hacker News, Reddit, dev.to, Product Hunt, Stack Overflow, and Lobste.rs — then uses an AI model to extract and score the underlying business problems. No manual curation, no paywall.

Pull from real discussion sources

Every 15 minutes, the system fetches trending discussions from Hacker News, Reddit, dev.to, Product Hunt, Stack Overflow, and Lobste.rs — real threads where people describe real frustrations and unmet needs.

AI extracts the underlying problems

An LLM reads each discussion and identifies the actual business problem — not the discussion topic, but the specific pain point a builder could solve. Problems are scored by volume, urgency, and opportunity.

Score by opportunity, not hype

High — many people have this, it's painful, and existing solutions are weak. Medium — a real pattern, but narrower. Emerging — early signal worth watching.

Always free, always live

Nothing is metered, gated, or drip-fed. The full list, on every visit, for everyone. It refreshes automatically so it always reflects what people are complaining about right now.

How Field Index compares to other idea tools

There's a real, and growing, category of "find your next startup idea" tools. Here's how this one is different, stated plainly so you can pick the right tool for what you actually need.

Tool	Cost	Sign-up required	Idea source	Best for
Field Index	Free	No	AI-extracted from live HN, Reddit, dev.to, Product Hunt, Stack Overflow & Lobste.rs discussions	A fast, transparent, auto-refreshing scan of real problems
IdeaBrowser	Free tier, paid tiers roughly $39–99/mo	Yes, for paid tiers	AI-scored Reddit & search-trend data, refreshed daily	Ongoing trend-tracking for investors and agencies
GummySearch	Paid subscription	Yes	Reddit pain-point and keyword monitoring	Deep-diving one niche you've already picked
Exploding Topics	Paid subscription	Yes	Search-growth and trending-topic data	Spotting rising interest before it peaks
Bulk AI idea databases	Usually free or low-cost	Varies	Large volumes of AI-generated ideas, scored automatically	Casting a wide net when quantity matters more than depth

None of these are mutually exclusive. A common workflow: scan a free, curated list like this one for direction, then use a paid trend or Reddit-monitoring tool once you've narrowed in on a specific niche worth digging into.

Frequently asked questions

What makes a business problem "in demand"?

A problem is genuinely in demand when the same complaint shows up repeatedly and independently — in support tickets, app reviews, forum threads, and casual conversation — and when people are already spending time or money on an imperfect workaround. One mention is an anecdote; the same friction described the same way by many unrelated people is a real signal.

How do I validate a SaaS or business idea from a list like this?

Start by talking to 8 to 10 people who match the "who feels it" description for that problem. Ask how they currently handle it, what they've already tried, and what they'd be willing to pay for a better fix. If they can't describe a current workaround, the problem may not be painful enough yet to build around.

What's the difference between a searched keyword and a real problem?

A searched keyword tells you people are curious about a topic. A documented, recurring complaint tells you people are frustrated enough to want it fixed. The second is the stronger signal for a business — search interest alone can reflect curiosity, research, or a one-time need rather than a standing, payable problem.

Is the demand signal on this site based on real search-volume data?

No. The signal score on each entry is calculated by an AI model based on how consistently a problem appears across forums, reviews, and support conversations — it is not pulled from a live keyword-volume API. For actual search-volume numbers, pair this with a tool like Google Trends, Ahrefs, or Semrush before committing to an idea.

Is this list only for SaaS founders?

No. It covers three kinds of opportunity: software problems suited to a SaaS product, everyday operational problems suited to a service or local business, and content gaps suited to a niche site, directory, or publication.

Is there a free alternative to IdeaBrowser, GummySearch, or Exploding Topics?

Field Index is free, requires no sign-up, and shows every entry on one page rather than gating a database behind a subscription. It's not a full replacement for those tools — it doesn't pull live search-volume or Reddit-monitoring data — but it's a genuinely useful free starting point before paying for a more specialized tool once you've narrowed toward a niche.

How is this different from an AI-generated idea list?

Most AI idea lists generate generic business ideas from search data. Field Index does the opposite — it reads real discussions where people describe real frustrations, then extracts the underlying problem. Each entry points to actual source threads you can read yourself, grounded in real complaints rather than generated in bulk.
