I’m the founder/CEO of Lebesgue — a group of data science experts specialized in the online growth field. We’re focused on building mathematical models that make your growth scalable and profitable. We help start-ups analyze and improve their user churn, lower retention, increase product lifetime values (LTV) and a website’s average-order-value (AOV). We also scale advertising performance to improve low return-on-ad spends and return-on-investment (ROAS/ROI). The main questions we tackle are: Can your growth curve improve? Is your growth scalable? What do you need to do to achieve exponential growth? Presently we work with successful startups like Dropps, Plume, OptimoRoute, RaeWellness. Results we’ve achieved so far: — 2 apps hitting #1 in the US app store — Growing website traffic from 50k visitors to over 1M visitors monthly with paid advertising (profitable with the overall return on ads spent around 200%) — Growing and managing the biggest European Facebook and Pinterest ad accounts — Building a mathematical model that improved user LTV by over 30% — Reducing churn and improving retention on apps with over 1M users Check us out on www.lebesgue.io. Besides Lebesgue, I have a Master of Science in Applied Mathematics, and I’ve been working on applying mathematical models in physics and computer science. Currently I’m trying to fit that knowledge in the online advertising/e-commerce field. My interests span from game theory and its application in online auction systems to machine learning, statistics, and behavioral economics.
