I'm Ilya
I've spent 22 years asking one question: how do good businesses actually grow? The answer is usually one level deeper than where most people stop looking.
The path
The path made sense in reverse. At seven I built my first video game. At fourteen I knew eleven programming languages and ran with a hacker crew. Then I fell in love with marketing — not the loud kind, but the mechanism: how people think, how they choose, how you earn the right to show up in their lives.
I spent a decade in agencies, then eight years at Nike shaping membership, e-commerce, and partnership strategy across Europe — $65M budgets, programs touching millions of members, transformation work that connected retail, digital, and loyalty into single experiences. Now I lead marketing for developer tools at JetBrains, helping engineers navigate AI and an industry in flux.
Existentialism says there is no meaning in life — so I make my own. I'm drawn to entrepreneurial minds: people who add to the world, not just consume it. They often nail the product and miss the business. I'm on a mission to help good businesses grow.
What I believe
I'm chasing complexity I can take apart.
Ecosystems over channels. Membership over campaigns. Models over tactics.
Most growth problems aren't solved by more activity — they're solved by seeing the system clearly. The interesting problems sit one level deeper than where most people stop. That's where growth actually lives.
Some proof
- Nike, JetBrains, Zalando, Asos, AboutYou, P&G, Visa, Mars — hands-on, not advisory
- Full stack: advertising, comms, digital, e-commerce, DTC and wholesale retail, membership, loyalty, partnerships, new business models
- $100M+ connected loyalty investment, from strategy through operations
- Strategy Deck app — ~100K downloads, still in use
- Kellogg Executive Education (Customer Loyalty), Moscow State University (Math & CS)
Mostly, I'm a fan of three things: ideas, stories, and people. Ideas change the world. Stories are how ideas travel. And people are full of both.
What I'm building here
I built this site to think out loud — and to be useful.
Models are how I make sense of business problems. They're the structures underneath growth, pricing, positioning, loyalty — the mechanics that don't change even when tactics do.
Tools are models you can use. Templates, calculators, frameworks — things that save you time if you're building something.
Notes are the raw thinking. Observations, questions, half-formed ideas that might become models later.
If you're trying to grow something and want clarity before tactics, start with a model.

While I'm here
Last life, so I keep widening the world I can see. I make things to understand things.
