Every day, Engaggit scans Reddit for conversations where people describe exactly the app they wish existed — not in a survey, but in the middle of a real problem. This Monday's feed (covering Friday through Monday, Sep 25–28) surfaced five gaps so clearly defined that "build this" is already implied. Each idea below links to the actual thread, so you can read the full context before you commit a weekend to it.
This isn't a list of trends. Trends are what everyone already sees. This is a list of threads where someone hit a wall, looked for a tool, and discovered nothing quite fits. When you find a wall that thousands of people share, you've found a product.
The five ideas below came out of real conversations from Sep 25–28 — the window since our last post — with real scores, real frustration, and in a few cases, thousands of upvotes confirming the problem is universal.
1. AI-Search Visibility Attribution — "which AI is sending people to my site?"
Where: r/growthmarketing | Thread: Best AEO tools for tracking AI search visibility in 2026
The pain: Everyone is getting traffic from ChatGPT, Perplexity, and AI Overviews — but nobody can connect those "AI mentions" to actual sessions and revenue. The poster's core complaint: current AEO tools show vanity metrics (are you mentioned?) and screenshots, but they can't tell you which AI models actually drive visitors to your site, or whether those visitors convert differently than Google traffic.
Why it's promising: Every company is being forced to become "AI-visible," but "visible" and "profitable" are two different things. The tool everyone has stops at the mention; the tool nobody has answers "did the AI mention turn into a lead?" This is an immediate, 2026-relevant problem with budget behind it — growth teams are already spending on AEO, they just can't justify the ROI.
The product spec: An attribution layer that tracks AI citations (ChatGPT, Gemini, Perplexity, Grok, DeepSeek, AI Overviews), follows the full path to your site, and segments conversion by which AI mentioned you. Bonus: model-level alerts when a competitor's name starts appearing in answers where you used to be.
2. Publisher-Gatekeeping Database for Indie Game Devs
Where: r/gamedev (261 upvotes) | Thread: PSA for devs getting cold-pitched by Switch publishers
The pain: An indie team exposes how a Switch publisher pitched them, then never actually reviewed their build — just sat on the eval key and left the devs in limbo for months. The thread is a warning to everyone in the same position, and the comments confirm it's systemic: publishers cold-pitch, collect eval keys, and vanish, leaving small devs unable to shop the game elsewhere.
Why it's promising: Indie developers face a power imbalance they can't fix individually. A horror story with 261 upvotes and "this happened to me too" replies is a market screaming for a reputation layer. Game publishing is a multi-billion-dollar industry where the "suppliers" (indie devs) have zero visibility into who they're dealing with.
The product spec: A Glassdoor-style database for game publishers — verified track records, past titles shipped, average time from eval key to response, report-ability, and an "eval key verification" tool that proves whether a build was actually opened. Even a lightweight v1 is immediately valuable to every indie developer considering a publisher at all.
3. Offline-First BIM Tool for Small Architecture Teams
Where: r/Architects (47 upvotes) | Thread: A lightweight, offline-first BIM tool from scratch — what would make an indie alternative viable?
The pain: The thread is literally an open product spec from the target market — and the OP is actively building (the tool is called Northsill, currently Windows-first). Architecture pros shared exactly what would make an indie BIM (Building Information Modeling) tool viable for them, and the answers are remarkably consistent. The giants (Revit, ArchiCAD) are heavyweight, subscription-walled, and designed for big firms, leaving small teams overpaying for 10% of the features — but also afraid to switch: "practices generally use the big name software, even if they're not the best tool on the market," because the bigger risk is the tool itself going bust.
What the comments actually asked for — ranked by how loudly it was demanded:
| Ask | Signal |
|---|---|
| Custom library / family creation — parametric fixtures, furniture, electrical objects, from day one | Top comment, 16 upvotes; seconded repeatedly. "Even with Revit, locating and maintaining the family library is a massive time suck." |
| Documentation to paper — 2D drawing tools that make plans look like plans, not model views | 18 upvotes. "Full BIM is still just a nice-to-have. What counts are the signed folded paper plans for administrative officials and construction sites." |
| Mac and Linux support | 20 upvotes. "Focus on LINUX — you'd be the first to do so other than Blender." Consistently cited as the thing that would get people to switch. |
| Everything needed for a real workflow — site analysis, conceptual design, file import (DWG/DXF/PDF/3D), annotation, schedules, layout and print managers | 20 upvotes. "Even a single missing thing would totally stop me from actually making a move." |
| Standard details library — thousands of pre-built construction details | "Standard sets of details included — you will print money." |
| Version control and sync like Revit's | 2 upvotes |
| RVT file compatibility | "It would need to open and close RVT files." |
Why it's promising: The market is doing the research for you, and the spec is now public and tested. The top asks — parametric family creation, documentation-to-paper, cross-platform support, and a bundled details library — are exactly the features a small, fast indie tool can nail where enterprise suites are bloated and brittle. The thread is also proof of real hunger: architects openly cheering for a monopoly to be broken.
The product spec: Learn from the failed positioning here — a "field companion" niche is not what was requested. The comments demand a real BIM package: parametric custom-object creation (families) from the start, first-class 2D documentation that outputs print-ready paper plans, DWG/DXF/PDF import, schedules, layout/print workflows, and version control — on Mac and Linux, with a bundled library of standard construction details. Ship Windows first, listen loudly on the Discord, and treat "resilience" (the fear that an indie tool will vanish) as a product feature: public roadmap, export guarantees, and a migration story.
4. "Financial Archaeology" — Tracing a Deceased Relative's Stock Options
Where: r/personalfinance (1,6K upvotes) | Thread: Deceased relative had 30,000 employee stock options in old SEC filings. How do I trace what happened to them?
The pain: A person discovers, through old SEC filings, that their deceased relative held 30,000 stock options in a company later acquired at $48/share. But the paper trail — SEC forms, estate records, corporate HR conversations from 2002, transfer agent ledgers — is scattered, digital-archaeology-level detective work. The thread got 1,098 upvotes because so many families sit on unclaimed equity and don't even know it.
Why it's promising: 1,6K upvotes is a signal that's hard to argue with. People are walking around with potentially valuable, forgotten financial assets and no way to trace them. This has both a consumer product angle (estate planning tools) and a B2B angle (attorneys and estate executors who need to reconstruct equity trails as part of their job).
The product spec: A guided "trace your relative's equity" tool — inputs a name and company, walks through SEC filing archives, surfaces options grants, checks whether they lapsed or were exercised, and tells you exactly which records to request (transfer agents, tax returns, corporate equity plan administrators) at each fork in the road. Educational content + workflow + document registry, wrapped in a simple checklist UI.
5. Sales Conversation Analysis Focused on Coaching, Not Surveillance
Where: r/sales_intelligence | Thread: Best tool for sales conversation analysis?
The pain: Sales teams know they should analyze call recordings, but the existing tools are built for managers to police reps — scorecards, red flags, "talk ratios." The poster wants tooling that coaches rather than monitors: turn every recorded call into an opportunity to get better at objection handling, not a performance review.
Why it's promising: The incumbents (Gong, Chorus) are enterprise-priced and manager-centric. There's a gap for a coaching-first, rep-loved tool at an indie price point — the person on the call wants to improve, and the current products treat them as the subject of surveillance, not the customer. Every seller is aware of their calls being "analyzed," but almost nobody enjoys it.
The product spec: Analytics that answer "how can I get better?" instead of "what did you do wrong?" — objection-handling breakdowns, follow-up triggers, sentiment where it matters, and actionable micro-coaching. Ship it for teams too small for Gong (the 5-to-50-person segment), and position it as the tool the rep picks, not the one management imposes.
How These Were Found
This list comes from a daily feed: Engaggit scans a set of subreddits, scores every matching post by relevance, and drafts a summary connecting what people said to what they need. No surveys, no echo chambers — just people describing real problems in their own words, scored and surfaced while the conversation is still fresh.
The thread quality is the button you can't press in a survey. When someone writes "I want a tool that does X instead of Y," in the middle of an actual problem, that's a validated product spec — and there were 21 such conversations in the Sep 25–28 window.
