Frequently asked questions
Can AI do market research as well as a consultant?
For early-stage scoping — market sizing, competitor mapping, positioning — AI tools now produce consultant-grade first drafts in minutes instead of weeks. Founders360 beta users report saving ~40 hours of manual SWOT and sizing work. For proprietary primary research (large surveys, expert panels), humans still lead.
How does Founders360's Market Researcher work?
You describe your idea and audience; the agent produces market sizing (TAM/SAM/SOM), a competitor landscape, SWOT, positioning, and customer survey scripts. Everything is saved as shared context, so the GTM Strategist, Financial Modeler, and Pitch Deck Builder reuse it automatically.
What's the best free market research tool for a startup?
Founders360's Market Researcher is on the free plan (forever, no card), which makes it the most complete free option for startup-specific research. Perplexity's free tier is the best general-purpose complement.
Should I validate my idea before building?
Yes — it's the cheapest failure-prevention available. Run market sizing and a competitor scan first (10 minutes with AI), then talk to real customers using generated interview scripts. Founders360's AI Red Team will also argue against your idea so you hear the objections early.
