Score any business idea against six live market signals before you build
Every idea receives a 0-100 score spanning demand, pain, competition, monetization, funding momentum and urgency, so you can compare concepts on one scale.
Hundreds of public sources are re-read daily, including funding rounds, search volume, purchase-intent share and community complaints.
Reports name direct, marketplace and content competitors and describe the dominant acquisition channel, helping you judge whether a wedge is realistic.
Submit a concept you already have and get the same pillar-by-pillar breakdown plus cited evidence instead of a generic verdict.
