I mentored Denis with his project Smartsub and helped him with the product development strategy. Denis showed himself as an experienced manager with great communication and organizational skills. With his experience in marketing and new product launches, I believe, he will be a valuable player in product teams focused on growth due to his ability to generate and validate product growth hypothesis and clear communication.

Denis was my teacher at the Growth Hacking Marketing course in IBA Institute. Denis is a good example of an amazing teacher who is passionate about what he does and obtains knowledge in sales and marketing at the expert level. High professionalism, vast experience, extensive knowledge in the field of marketing, the ability to present information — this is what distinguishes Denis from other teachers. He paid attention to the project of each of his students, gave us a huge amount of additional material, advice and recommendations. I apply all this in my work. I recommend Denis as a high level professional in the field of sales and marketing.
