My first engagement with Avantous was on a project of digital marketing. The company brought along good expertise that involved targeting the right customer audience through use of effective and creative digital marketing campaigns. The feedback and result were phenomenal compared to our previous marketing strategies.

I was approached by this company (Avantous) at the later part of 2019. Initially I was hesitant to work with the guys since they were new. However having a chat with them, it made me realize that they know their stuff. So I went ahead and signed up with the guys and yet partners to date. They have done a fabulous job for my restaurant. I would happily recommend them as they would pay good attention to your brand and do the right thing.
