Updated Oct 2, 2026 · Pricing checked against public sources; confirm on IdeaWave’s site.
IdeaWave publishes a validated startup idea every day, anchored to the monthly revenue of startups it tracks, and sells done-for-you v1 builds. Proofline focuses on the step before that: telling you quickly whether the idea already in your head is worth the weekend.
