Company Overview

Online advertising is fundamentally broken - advertisers are spending $75B+ per year to reach their audience online, but are getting steadily diminishing returns as users automatically tune out ads by developing 'ad blindness' or by using solutions like AdBlock. That's why we created Imprint.

Imprint ( is the world's most engaging native ad unit. It delivers genuinely enjoyable ad experiences containing original user-generated content, as opposed to typical online ads that users do their best to avoid. Imprint engages its audience 10 times more than the average ad - users spend between 80-160 seconds engaging with an Imprint (vs. < 15s with regular ads) - and delivers 30-50% better performance metrics across viewability, interactions, and message recall. Within 6 months of launching, Imprint is already being used by Amazon, Disney, Com2uS, Sony, ESPN and The Honest Co., with several more Fortune 50 brands in the pipeline.

Imprint creates a fun and non-invasive ad experience by packaging original content created by its own network of expert contributors, along with the brand's promotional assets (images, videos, infographics, social posts etc.) into a customizable unit that adopts the look-and-feel of the page that it's placed on. The original content is in form of posts - discussions comprising a topic related to the advertiser's message along with short opinions from multiple experts. The algorithms powering Imprint generate targeted contextual placements for these units, and collect performance and demographic data to automatically optimize their content and placements. Imprint has a reach of 220M+ unique users and can be plugged into any site, app, ad network, or ad server.

Imprint has been developed by the team at Sidelines Inc., comprising MIT, Berkeley, Penn, Hopkins, and Michigan alums with years of experience at Microsoft, Twitter and theAudience.
