IdeaValidator: Marketplace for Real Customer Feedback on Rough Ideas

A lightweight Figma/Slack plugin + web form where developers post a 1-minute video pitch + rough wireframe of their idea, and real potential customers (pre-screened by vertical) watch and give structured written feedback on: would they use it, what price, what's missing, deal-breakers. Founders get 10-15 responses in 48 hours with a simple scoring dashboard showing demand signals.

PLUGIN

25 weeks • 70% confidence

Value Proposition

Faster than interviews (48-hour turnaround vs. 3-4 weeks), cheaper than a validation service ($200-400 vs. $3,500), more honest than friends/family feedback, and gives you actual pricing data. Beats surveys because responders see a real pitch, not abstract questions. Beats building an MVP because you iterate on the idea itself before coding.

Target Audience

Solo developers, early-stage technical founders, and indie hackers (ages 22-40) building in public or early-stage; typically pre-MVP, want fast feedback loops, comfortable with async feedback

Key Features

  • Figma plugin: embed idea wireframes directly into feedback form (no separate uploads)
  • Slack integration: post idea to a channel, get feedback responses piped back into Slack thread
  • Pre-screened feedback pool: founders tag their ICP (e.g., 'B2B SaaS founders,' 'freelance designers,' 'remote workers'), system matches to relevant feedback givers
  • And more, with full implementation detail...

Tech Stack

Figma plugin SDK (JavaScript) React (frontend dashboard) Node.js/Express (backend) PostgreSQL (user data, feedback responses)

Original Problem

Developers lack reliable tools to discover and validate profitable business ideas before building

Software developers and technical founders struggle to identify which product ideas people will actually pay for, leading to wasted months building solutions nobody wants. Current validation methods are either too vague (surveys, focus groups) or require already having a product to test. Developers need a systematic way to validate market demand and willingness-to-pay before investing significant development effort.
