Questions

What is free, and what is paid?

The ideas, the evidence, and the market estimates are free, and you can start any of these businesses. The business-plan prompt and the growth playbook are paid: one credit ($9.99, or less in a pack) unlocks both for one business. Credits work on both businessideastobuild.com and realstartupideas.com.

Which lighter operations idea has the strongest demand signal?

Dementia Conversation Cue Cards, scored 4.05. The score falls as the evidence ages, unless a later report adds a newer public thread.

Do I need an account?

Only to unlock prompts. Reading is open to everyone. You sign in once with your Real Startup Ideas account, and one wallet of credits works on both sites.
