Yonatan reveals his unique methodology. This is a set of practical principles that prioritizes early profitability and real customers over trendy slogans. He demonstrates how building a billion-dollar company is not about luck. It is about following a logical, repeatable process that anyone can master. Yonatan Stern, Technion alumnus (BSE, MSc), is an Israeli-American scientist and serial entrepreneur. Yonatan is the Founder of multiple high-tech companies including Zoom Info, and has sold four companies for over a billion dollars.

This lecture argues that the fundamental principle of building a startup is to reach profitability as quickly as possible, rather than relying on a continuous cycle of fundraising.
Despite securing tens of millions of dollars from venture capital firms, 9 out of 10 highly talented, well-funded startup teams still fail because the startup ecosystem lacks a tested “engineering discipline” for building companies.
A company must sustain itself without continuous capital injections; constantly losing money and relying on new financing rounds leaves a startup highly vulnerable to collapse when it eventually becomes impossible to raise more money.
Marketing and demand validation must come before product development. By running campaigns before a product even exists, founders can verify market demand, test messaging, and save significant money by developing only the specific features that prospects actually need.
Generating real cash flow grants founders the strategic freedom to grow their business and even use excess cash to spin off entirely new, successful companies.
How SmartUp frames this:
SmartUp, a school and residency program for startup founders, frames profitability as the foundational principle in a necessary “engineering discipline” for building companies.
This discipline shapes every early decision to keep expenses to a minimum while maximizing sales. SmartUp teaches founders to validate demand before building anything, to minimize costs by utilizing off-the-shelf components instead of inventing disruptive technology, and to prioritize developing disruptive business models over being the first mover in a market.
Building a Thriving Hi-Tech Company is Easier Than You Think | Yonatan Stern | TEDxTechnion – February 16, 2026

Why fail if you can succeed? Building a thriving high-tech startup company is easier than you think. Founders who build high-tech startup companies dream of great success, of fame and big headlines, of an exit worth hundreds of millions of dollars. But the reality is much darker. Only one in ten companies have an exit, and only a handful of those will be a huge exit. And my first company, Rosh Intelligence Systems, was one of the nine that failed. And here is me in my late twenties, standing in front of the office.

Rosh developed an advanced AI system. Back then, it was called an expert system. Sales grew nicely quarter after quarter, and so did our expenses, and we lost money every single quarter. That forced us to keep raising money. We raised eleven million dollars in four rounds of financing, until it became practically impossible to raise more money. And we ran out of money and the company shut down. After seven years of hard work and sleepless nights, the company collapsed. Let me share with you, failure feels horrible and humiliating. Took me six months to gain enough confidence to start another company, CardScan. Rosh failed because it ran out of money, and the first lesson I learned the hard way was to bring the company to profitability as quickly as possible. It became profitable within three years and started generating real money thereafter. Using that money, we spun off another company, ZoomInfo, which also became profitable in three years and generated excess cash, which we used to spin off a third company, BizO. Successful companies attract buyers, and we sold CardScan in two thousand and six. BizO was acquired in two thousand and fourteen by LinkedIn. And ZoomInfo is now a public company valued about three and a half billion dollars. The power of being profitable and of generating cash. Being a scientist and an engineer, I started thinking about and researching why nine out of ten companies fails.
