Our story

01 · 2013
A gift card platform
Our story begins with a gift card platform we founded in 2013. After being hit with a very high chargeback rate on week one, we searched for a premium payment fraud protection solution that fits our type of product – and couldn’t find one.

Declining the wrong people
The market was filled with only payment fraud protection solutions that required us to decline 15%-20% of what we knew were legitimate shoppers who had gone through the entire purchase flow and provided us their payment information!
03 · 2013
Built in-house
To meet our specific needs for prepaid & gift cards, we created our own in-house payment fraud prevention platform. It soon became clear that we weren’t the only merchant looking for such a solution.

nSure.ai is born
After consistently testing our machine learning models against leading payment fraud protection providers, in 2019 we saw an opportunity to make a greater difference in the crypto, gaming, and prepaid & gift card industries – and nSure.ai was born.

Spun out
Spun out of the giftcard platform, nSure.ai was co-founded by Alex Zeltcer and Ziv Isaiah, with the backing of Kamet, AXA’s venture builder at the time.
