I built a site that researches SaaS opportunities before you waste months building one
A lot of us have built products that nobody wanted.
The hardest part isn't building anymore it's finding an idea that actually has real demand.
That's why I built Build Signals.
Instead of generating random startup ideas, Build Signals researches markets the way an analyst would. It looks for real signals like:
Regulatory changes creating new markets
Companies actively hiring for a specific problem
New APIs or platform changes
Growing demand from developers and businesses
Weak competitors and underserved niches
Then it produces a complete opportunity report including:
Opportunity score
Market analysis
Competitive landscape
Customer acquisition strategy
Revenue estimates
MVP roadmap
AI coding prompts to build it
Evidence and sources behind every recommendation
Today I even published a fully researched opportunity directly through the Build Signals API.
The goal isn't to replace founders.
It's to help founders spend their time building things people are actually willing to pay for.
I'd genuinely love feedback from other makers:
Would you trust AI to help choose what to build?
What signals would make an opportunity convincing enough for you to start building?
Happy to answer any questions or hear feature requests.

One useful lesson from early feedback: founders do not need more ideas. They need enough evidence to make a decision.
The strongest example so far was an AI inference-cost governance opportunity. One founder used it to plan an internal dashboard tracking cost by user, feature, model, and request type.
Before you would commit two to four weeks to an idea, which evidence would matter most?
1. People already paying for workarounds
2. A regulatory deadline
3. Repeated complaints from a narrow buyer group
4. Weak existing competitors
5. Something else
I will use the answers to improve how Build Signals scores opportunities.
