Hello!

I'm Ekaterina, a growth and marketing enthusiast. I help B2C companies and mobile apps unlock revenue growth and specialise in marketing-led and product-led growth strategies. Throughout my professional experience spanning over 15 years, I'm noticing a merging of marketing and product growth disciplines. Aligning these two areas and understanding the entire funnel and product growth models has been a pivotal aspect of my work. My skills in user acquisition, marketing strategy, data analysis, revenue optimization, and user research enable me to implement effective tactics with swift results. While my expertise in product management, user engagement, growth modeling, and retention contributes to driving sustainable long-term user and revenue growth.

Gene Kamenez
CEO at Uxcel
It was the most helpful and informative conversation I've had in the past few weeks. I’ve started exploring ASO more deeply for my new project, Storist.me, and in just one hour, I’ve gained a lot of insight into my strategy. More importantly, I’ve also learned which steps I don’t need to take right now, helping me save on unnecessary costs.
Andrew Zavada
CEO at Storist.me
Ekaterina was excellent at diving into marketing channels for my startup's growth. She was also able to do something so few professionals in marketing can, provide estimates for different campaigns I could run. On top of being up to date with the nitty-gritty details of marketing channels, she's also a great leader who can communicate outcomes.
Peter Antonov
Founder and CEO at ShopppMe
Ekaterina always has bags of insight and is able to back up her ideas and recommendations with first-hand experience. When asking her about our specific issues with scaling meta ads and improving ROAS, she was able to provide both product and marketing tactics that could help us. She always has resources, articles, presentations, and useful content to further explain and guide you on how to approach her recommendations. Ekaterina has provided some of the clearest and most practical advice.
