Market scanning from public sources
Reads signals from Reddit, app stores, Hacker News, the open web, and similar sources to surface complaints and unmet needs in a market.
ShouldBuild
BeanspruchenShouldBuild helps founders validate an idea by scanning market complaints, reviews, threads, and competitor signals, then turning them into a market report and roadmap. It is aimed at people deciding what to build next and whether the opportunity is worth pursuing.
Validate product ideas using live market signals
ShouldBuild analyzes public complaints, reviews, threads, and other market signals to help founders decide whether an idea is worth building. It combines those findings into a report with a verdict, supporting quotes, competitor context, and a roadmap-oriented view of what to do next.
The product is built around a repeatable workflow: discover gaps in a market, validate a concept, decide what makes the cut, turn research into backlog items, and revisit the market later to see what changed. The site positions this as a way to avoid spending months building before learning whether demand is real.
Core capabilities
Verdict-based idea evaluation
Generates a plain-language judgment such as build, build with caution, depends on niche, or not worth it, based on the evidence it finds.
Evidence-linked market reports
Each finding is backed by quotes and links to the source post or review, so users can review the underlying signal rather than just a summary.
Competitor and category mapping
Shows how an idea sits among rivals and highlights whether a category is crowded, saturated, or still has openings.
Decision board and backlog flow
Lets users save findings on a board, sort them by decision state, and turn selected insights into backlog tasks.
Ongoing market monitoring
Re-checks competitors, prices, ratings, and new complaints over time so users can compare a new run against prior research.
Typical ways to use ShouldBuild
Testing a new product idea
A founder can describe an idea and get a research-backed verdict before spending time on design or development.
Scanning a market for unmet needs
Users can enter a market, such as a category of apps, and review the gaps and pain points that real users keep mentioning.
Comparing a concept against competitors
The report helps teams see whether a space is dominated by existing leaders or whether there is room for a narrower wedge.
Turning research into execution
Findings can be moved into a board or backlog so the output from research becomes specific product work instead of a dead-end report.
Watching a market after launch
Teams can revisit a category over time to track new complaints, pricing changes, rating shifts, and newly opened opportunities.
