Real shoppers.
Real stories.
Flagged a fake Nike store before I entered my card. I had no idea it wasn't real. I would have paid.
Rachel S.

Got a phishing email that looked exactly like my bank. ShopSherpa caught it. I'm not a tech person and it just worked.

I always suspected some reviews were fake. Now I actually know which ones. Complete game changer.

The story
His mom lost $600 to a fake puppy listing.
That's why this exists.
After weeks of begging for a dog, the money was wired and the seller vanished. The puppy never existed. That emotional toll turned into a mission.
At 16, Anghelo has completed Harvard's CS50 curricula and MIT Beaver Works programs in Quantum Software and Microelectronics. He interned at Rayfield Systems and competes in DECA and Track.
ShopSherpa is his answer: an AI-powered shield that stops marketplace fraud before it hits your wallet, so no other family goes through what his did.
