About ProofSpark

We're on a mission to help entrepreneurs validate their ideas before investing time and money into building them.

Built by Entrepreneurs, For Entrepreneurs

15km LLC, the company behind ProofSpark, was founded in Delaware, USA with a simple belief: every entrepreneur deserves to know if their idea will work before they invest everything into it.

We've seen too many brilliant people waste months and fortunes building products nobody wants. That's why we created ProofSpark - to give you the confidence to move forward or the wisdom to pivot early.

Our unique approach combines cutting-edge AI analysis with real-world market testing, giving you the most accurate validation possible in just 7 days.
