Proof (YC W18) careers

We increase website conversions through personalized social proof.

Websites using Proof tap into human psychology by showing their visitors what others like them are doing on the site. Examples include how many people have signed up in the last day or how many people are currently viewing a product.

You’ve already seen travel sites like Booking.com and Airbnb doing this themselves. In fact, adding live social proof has been the number 1 driver of increased revenue for Airbnb over the last few years.

But most businesses can’t build this technology themselves, so we are.

Businesses are looking for ways to increase trust and transparency with their customers, and Proof is the answer.

We’re mapping customer behavior across our network of sites to learn what actions actually make them buy.
We can combine this information with machine learning to personalize every part of the marketing funnel for conversion.
