More than a decade ago our founders got started building a new category of products at PayPal and FedEx to protect online retailers from fraud.

We found that existing solutions only provided retailers with a cryptic score and relied on human expertise alone to ultimately decide whether or not to accept a transaction. We soon realized online retailers were in need of a simple yes or no decision, but such a product did not exist, and Signifyd was born.

For the first time, online retailers can receive a decision backed by a 100% financial guarantee against fraud. We focus on making commerce safer for online retailers, so that they can focus on what they do best: growing their business.

Technical Challenges

We have extremely compelling technical challenges across a number of different areas:

1) Machine learning problems to classify transactions as fraudulent or not.

2) Scaling our data infrastructure as we continue processing a larger volume of transaction data.

3) Optimizing the speed of our service. We use all available payment, user, and machine data in order to separate legitimate credit card transactions from fraudulent in under 400ms. That means doing just-in-time analyses of our internal data with external APIs and reducing it all into a single score with a few critical insights for end-users.

4) User experience - we care immensely about making our product as simple as possible for merchants to use and understand.
