Anyone can be visible online. But not everyone can do so while actually making a significant business impact. Quanta believes that through Performance Marketing, we can make your business grow, maximizing your revenues from all available marketing and eCommerce platforms, all while spending efficiently.

Our aim is to help you determine for each of your online marketing campaigns a point where spending more no longer provides an added value, and help you maximize your sales with the lowest cost possible. Let us get to know your business better and we’ll help you create a rock-solid strategy to reach your goals.


With over 5 years of Performance Marketing experience delivering exceptional performance for the Philippines’ biggest eCommerce platform and its brand partners, we have decided to finally get out there and drive the industry further by helping more businesses expand online.

We believe that our exposure to the various stages of eCommerce marketing maturity will help us to successfully build you an efficient online marketing campaign portfolio and will allow us to effectively devise strategies based on your priorities – from customer acquisition to retention, and to reach sales targets.


We are a team of passionate marketers and data scientists
who wants to change the way we do
Digital Marketing in the Philippines. We’re looking forward to learn more about you and
to discuss how we can help you grow your company online. Let’s bring your business to new heights!
