Find markets with real demand and weak execution.
We analyze 169K+ user reviews and revenue signals to help you answer a harder question: is this a market worth building for, or just another good-looking trap?
Primary signal source: AppSumo and adjacent public market data.Best used for early-stage SaaS decisions, not broad enterprise procurement truth.
A decision filter for builders. It helps you find markets where users are already paying and still visibly unhappy.
It is not a guarantee of product-market fit, and it is not a full map of the SaaS economy. You still need channel fit, category judgment, and outside validation.
Built for people who can ship. Not for people who just want more data.
SumoTrends should answer one question before you write code: is this market worth your next serious bet? The job is not to impress you with dashboards. The job is to narrow your decision surface.
Indie hackers with ship speed
You can build fast. The problem is choosing a market that deserves the next 30 days.
Agencies looking for product bets
You already have delivery capacity. You need narrower, less random ideas to productize.
Operators screening small acquisitions
You are not looking for perfect companies. You are looking for demand with visible execution gaps.
What demand already exists
Revenue, reviews, and category context tell you whether this is a real market or launch noise.
Why incumbents are weak
Negative sentiment, feature bloat, pricing friction, and product decay become structured opportunity signals.
Why this signal may mislead you
Every opportunity should come with a counter-case: AppSumo bias, weak retention, cheap users, or crowded channels.
These signals are strongest for early-stage SaaS, solo-founder bets, and products where execution quality matters. They are weaker for heavy enterprise software, procurement-led sales, and categories where AppSumo users are a poor proxy.
Real products. Real friction.
Start with a small shortlist, not a giant database. These examples show the kind of market we care about: proven demand with visible execution gaps.
PowerIn - Automate LinkedIn Comments
Product downgrades features after purchase (bait-and-switch tactics)
Don't build another LinkedIn bot—build the one that doesn't lie.
FreshLMS
Storage lockout system feels predatory - can't delete, only upgrade
Don't build another LMS - build a 'No-Lockout' LMS that respects creators instead of holding their content hostage.
Retable
Lifetime deal terms being changed, denied, or reneged upon, causing financial and trust loss.
Don't build a database tool; build one that doesn't scam its users.
Choose the level of decision support you need
Start with a lightweight market check, then upgrade only if you want deeper filters, stronger counter-signals, and clearer execution guidance.
The Explorer
For checking whether this workflow fits how you evaluate ideas.
The Hunter
For founders narrowing a market shortlist before they commit to one direction.
The Architect
For serious builders who want clearer judgment, not just more rows.
Best for founders choosing what to build in the next 30-60 days.
Agency
For teams that want a shared research workflow and reusable market briefs.
`Explorer` is enough if you are just pressure-testing the product. `Hunter` fits founders building a shortlist. `Architect` is the right tier when you want sharper judgment, reusable briefs, and fewer false positives.
