Resource hub FAQ
Are these startup resources really free?
Yes. Every guide, template, calculator and Q&A on this hub is 100% free with no signup required. The free AI validator gives you 90 credits on signup — enough for a full validation plus a market analysis at zero cost.
Where should I start as a first-time founder?
Start with the AI Business Idea Validator on the homepage to test your concept in 120 seconds. Then read the Complete Idea Validation Guide, run the Market Size Calculator for TAM/SAM/SOM, and download the Lean Canvas template.
How are the resources organised?
They follow the founder journey: validate → research the market → plan finances → build & launch → grow. Use the sticky navigation at the top to jump to the section you need.
Which industries are covered?
We have dedicated validators and idea databases for SaaS, B2B SaaS, fintech, healthtech, AI/ML, ecommerce, marketplace, mobile, edtech, foodtech, proptech, traveltech, gametech, cleantech, agritech, insurtech, legaltech, HRtech, retailtech, spacetech and sportstech.
What makes IdeaProof different from generic resource hubs?
Every resource ties back to a working AI tool. Read a guide, then run the same workflow in 120 seconds on your own idea. Plus, our recommendations are grounded in 10,000+ real validations and 1,000+ documented startup failures.
How often is the hub updated?
Calculators use live market benchmarks. Guides and Q&As are reviewed quarterly. The startup failure database is synced continuously, and the blog ships 2–4 new pieces every week.
Can I use these resources for client work?
Yes. Consultants, accelerators and educators are welcome to use the templates, calculators and frameworks with clients. Attribution back to ideaproof.io is appreciated.
Do you have country-specific failure data?
Yes — the Failed Startups section breaks down by country (Australia, Brazil, Canada, Indonesia, Nigeria, Singapore and more) so you can study local patterns.
How accurate is the AI validator?
Our validation engine has an 89% accuracy rate validated against 1,000+ documented startup outcomes. See the Research Methodology page for the full methodology.
Can I suggest a missing resource?
Absolutely. Reach out via the Contact page — we add new tools, calculators and Q&As every month based on founder requests.
