Validate startup ideas before you spend months building them
Hi Indie Hackers 👋
Over the past few months I've been building a small project called Venture3Sixty.
The goal is simple: help founders validate startup ideas before they spend months building them.
You describe your idea, and the tool generates realistic assumptions and runs it through a venture model.
It produces a feasibility workbook including:
• venture viability score
• 36-month financial projections
• sensitivity analysis
• key risks
• a 90-day validation plan
I built it because I kept seeing founders build products for months only to discover the economics didn't work.
The calculator is free to try and I'd love feedback from other founders.
What’s the hardest part for you when validating a startup idea?

I launched Venture3Sixty on Product Hunt today. It helps founders validate startup ideas with a venture score, projections, and a feasibility workbook. Would love honest feedback.
Curious how other founders validate startup ideas.
Do you usually build financial models before building a product, or just test the idea quickly with an MVP?
