When StackAdapt raised $235 million in February 2025, it wasn’t just another funding announcement. It was the culmination of 12 years of disciplined execution, capital efficiency, and a willingness to do things the hard way. StackAdapt’s total funding is now over $500 million.
Founded in Toronto in 2013, StackAdapt built a multi-channel programmatic advertising platform that now stands as one of Canada’s most successful tech scale-ups.
StackAdapt’s CEO Vitaly Pecherskiy was a speaker at CIX Summit 2025 and shared his startup’s inspiring growth journey. Ponomarev is the first to admit their path wasn’t obvious or easy.
1. Culture Is Infrastructure, Not an Afterthought
Too many companies treat culture as something to layer on later or relegate to HR initiatives. StackAdapt took the opposite approach from day one.
“Culture is infrastructure,” says Ponomarev. “When individuals inside a company are aligned, supported, and clear on expectations, the organization performs better. That is not theory; it is operational reality.”
Culture shapes how people make decisions when no one is watching. It determines how teams respond under pressure and how leaders show up during uncertainty. As StackAdapt grew, the leadership team became more deliberate about reinforcing their values and ways of working together.
The cost of neglecting culture is misalignment, which gets expensive fast as you scale.
2. Capital Efficiency Creates Better Companies
In the early days, StackAdapt’s founding team faced a harsh reality. They were in their mid-twenties, had little startup experience, and were building ad tech in a market where many investors had been burned before.
Matt Leibowitz, Co-Founder of Plaza Ventures and an early investor in StackAdapt, recalls pitching the company to eight or nine other VCs. Everyone passed. The consensus was clear: ad tech was a graveyard.
This forced StackAdapt to raise very little money and focus on cash flow from the start. “When your back is against the wall, it forces you to make decisions and really push that much harder,” says Leibowitz.
The result was years of profitability and sustainable growth without the organization collapsing under its own weight. The company spent years building internal capabilities that didn’t show up in press releases but created a foundation for scale.
“There is a real case for patience in company building,” Ponomarev notes. “It is not always the most glamorous path, but it compounds.”
3. Put the Company First, Always
One of the most striking moments in StackAdapt’s story came two years ago when co-founder Ildar Shar approached the board with an unexpected message: it was time for someone else to step in as CEO.
This kind of founder self-awareness is rare. Leibowitz calls it “one of the most self-aware moments” he’s witnessed in his career. The transition to Ponomarev as CEO happened smoothly because the founding team shared a core principle: put the company first.
“If the company is successful, individuals within that organization will be inherently more successful too,” explains Ponomarev. This philosophy extends throughout the entire leadership team and has been central to maintaining alignment for over 12 years.
The founding team has stayed together without drama by maintaining a no-ego approach and staying committed to building something big over the long term.
4. Execution Beats Everything Else
Consistent execution was the key to convincing Plaza Ventures to bet on StackAdapt when others passed.
The founders reached out via LinkedIn and came into the office with a simple pitch: let us show you what we can do. They asked to come back in two months to demonstrate progress.
“Not only did they hit their milestones, but they beat it,” Leibowitz recalls. “Which, especially in the early days, is extremely rare.”
This pattern continued month after month. The team could build and sell their product themselves, a critical capability that many founding teams lack.
Teachers Venture Growth, which led the recent $235 million round, emphasized that execution remained central even at scale. The company consistently delivered on its objectives, repeatedly proving it could do what it said it would do.
5. There Are No Real Shortcuts
Perhaps the most important lesson from StackAdapt’s journey is the simplest: sustainable success takes time and hard work.
“Don’t look for shortcuts,” Ponomarev advises. “Even in today’s environment, there’s so much popular culture around finding some kind of hack, getting to meaningful revenues in nine months. It’s really hard to build businesses at a large scale over a long period of time if you look through the lens of ‘what shortcut can I take?’”
The best outcomes happen through sustained effort over time. StackAdapt didn’t raise capital just because it was available. They raised when the business, team, and platform were ready for the next phase of growth.
“Financing is not the goal. It is a tool,” says Ponomarev. Every financing decision comes with tradeoffs around control, expectations, and pace. Founders need to be honest about those realities.
Building for the Long Term
StackAdapt’s story demonstrates that world-class technology companies can be built in Canada without abandoning long-term thinking or cultural integrity. The company immediately started selling into the United States and globally, which is why they often don’t appear in Canadian rankings despite being Toronto-based.
For founders and operators, the message is clear: build strong foundations, make disciplined decisions, and align people around a shared purpose. The hard way is often the right way, and over time, it shows.
As the company looks toward a potential IPO, the focus remains on performance. “If the business is cranking, the window is open for a company, even probably today,” notes Ponomarev. The team continues to drive growth, innovate, and win market share while waiting for the right moment.
The journey from three founders who barely knew each other to a company valued in the billions wasn’t about luck alone. It was about choosing the harder path consistently, staying aligned as a team, and building something durable.
Those are lessons worth learning, no matter what stage your company is at.
