"Unicorns aren't born from a single breakthrough or a brilliant idea. They're built by founders who stay true to themselves, pivot as needed, and execute with discipline. Igor's book captures what it takes to build that kind of endurance."
-Alex Bouaziz, cofounder and CEO, Deel
"Working with Igor has always felt different because he thinks like a founder, not a financier. In an AI era where founders navigate countless options, his message is refreshingly simple: focus is one of the last unfair advantages left. This book is the operating manual for founders who want to play the long game and scale globally."
-Jonathan Siddharth, founder and CEO, Turing
"In startups, the only variable you can truly control is focus: what you direct your time, energy, and attention toward. Over time, that focus compounds-in talent, product, insight, and customer trust-to create the nonlinear results that define great companies. Few understand this fact better than Igor Ryabenkiy. In Unicorn Focus, he reveals proven methods for honing your focus into the ultimate founder superpower."
-Andrew Filev, founder, Zencoder and Wrike
"The only rules worth following in startups are simple: Solve a big problem, build reliable systems, and stay tough when it gets hard. Igor's book lays out that frame with rare clarity and practical depth."
-Dovi Frances, founding partner, Group 11
"I've been lucky to work closely with Igor for many years and have seen unicorns grow under his wing. His advice has always been simple but hard to live by: focus beats brilliance. This book turns that philosophy into a framework-practical and painfully honest."
-Nick Davidov, cofounder and partner, DVC
"Unicorn Focus nails what most founders get wrong-not the idea, but the attention and focus. Igor doesn't just talk about focus; he gives you the frameworks to protect it in the chaos of building. Every founder who has ever felt stretched thin or overwhelmed will find something here that resets their perspective."
-David Walsh, founder and CEO, Limelight
"Nobody can hand you a formula to build a unicorn. But Igor's book gives you the principles and frameworks that dramatically improve your odds of success."
-Suman Kanuganti, cofounder and CEO, Personal AI
