About Us

1901 Newport Blvd. Costa Mesa

Qualaroo creates solutions to help companies identify and capitalize on more web visitor revenue opportunities. Our solutions are customizable and adaptive to offer visitors to your website the best possible engagement experience whether they access through a desktop, tablet or mobile device.

Qualaroo was founded by Sean Ellis, Alex Sherstinsky, and Jason Meresman. We are a team of marketers and engineers who found it surprising that marketers rarely understand the unique needs, intentions and frustrations of visitors to their website. We believe that by simply better serving the needs of existing website visitors, marketers can gain the power to unlock enormous untapped revenue growth potential in their businesses.

With a small snippet of code, Qualaroo makes it possible to target intelligent interactions by time on page, pages visited, number of site visits, referring source, or any internal data. These interactions can be used to gather insights about visitors, address their unique needs in real time, and ultimately turn them into valuable customers.

Qualaroo is backed by $5.5M in venture capital from leading investors, such as Polaris Ventures, True Ventures, Index Ventures, First Round Capital, and 500Startups.
