For someone who has played an outsized role in Vancouver’s tech sector, Dennis Pilarinos has spent much of his career avoiding the spotlight.
His résumé stretches from Microsoft and Amazon to Buddybuild, Apple, and now Unblocked. Along the way, he helped establish Amazon Web Services’ presence in Vancouver, built and sold a developer tools company, brought much of its team back together for another startup, and invested some of the proceeds in other entrepreneurs.
Pilarinos has rarely drawn attention to any of it. But as he works to grow Unblocked in an increasingly crowded market, he is beginning to reconsider that approach.
“There’s a lot of really cool stuff being built in Canada,” Pilarinos told Techcouver. “Canada broadly, and Vancouver specifically, is a key player in it.”
The problem, he believes, is that Vancouver has not done a particularly good job of telling that story.
Pilarinos studied computer science and business at Simon Fraser University before spending seven years in the United States. He eventually returned to Vancouver, where his career would take him through Microsoft, Amazon, Buddybuild, and Apple.
The decision to come back was deliberate.
“I came back because I wanted to vote with my feet,” he said. “Bolstering the Canadian tech ecosystem, Vancouver specifically, was something I was passionate about.”
At Amazon, Pilarinos was the first AWS employee in Vancouver and helped seed what would become a major local development centre. The operation began in temporary office space in Yaletown; today, Pilarinos estimates AWS employs between 3,500 and 4,000 people in the region.
He sees that growth as more than a win for one multinational. Large tech companies give local workers experience building and operating products at scale, creating a pool of talent that can eventually start companies or join smaller ones.
Unblocked is evidence of that process.
Roughly half of the company’s engineering team previously worked with Pilarinos at Buddybuild or Apple. The other half largely came from Amazon and Microsoft.
“Companies spinning out of these large anchor tenants is really important,” he said. “That’s how you build an ecosystem.”
Pilarinos applied that experience to Buddybuild, a Vancouver startup that made it easier for mobile development teams to build, test, and deploy applications. Apple acquired the company in 2018, bringing Pilarinos and his colleagues into the tech giant.
After leaving Apple, he eventually reunited many of the same people to launch Unblocked.
“We got the band back together,” he said.
For Pilarinos, the opportunity to work with that group again was one of the biggest reasons to start another company. So was a persistent desire to solve problems for developers.
“I’m a builder at heart,” he said. “I missed working with people to create something.”
Unblocked began with the premise that developers waste too much time searching for the organizational knowledge they need to do their jobs. Important context is often scattered across code, documents, conversations, and project management systems—or exists only in the memories of longtime employees.
The Vancouver company brings that information together so developers can understand not just what was built, but why particular decisions were made.
Four years after Unblocked’s founding, the emergence of AI agents has made that problem even more pressing.
Pilarinos says today’s AI models can be remarkably capable but remain deficient when it comes to company-specific context. An agent may know how to complete a task, but it does not necessarily know how that particular organization completes it. Without that knowledge, it can invent a new process when a proven one already exists.
Unblocked initially delivered answers through interfaces designed for people, including a website and a Slack bot. It now also provides organizational context directly to AI agents. Pilarinos says agent-driven usage of the platform surpassed human usage months ago.
“We started solving it for people,” he said. “Now increasingly, it’s their agents that need it.”
The shift positions Unblocked at the intersection of two areas that have defined much of Pilarinos’s career: developer tools and emerging computing platforms.
It is also happening during an explosion in competition. When Pilarinos raised money for Buddybuild, he recalls venture capitalists telling him there was no money in developer tools. Today, new developer-tool companies appear almost daily, many built around generative AI.
Unblocked is responding by keeping its team focused. Pilarinos rejects headcount as the defining measure of a tech company’s importance.
“The measure of success isn’t the number of people who work at a company,” he said. “It’s the number of people impacted by it.”
That philosophy extends beyond Unblocked. After Buddybuild’s acquisition, Pilarinos set aside a portion of his proceeds to reinvest in the local tech ecosystem. He has made a dozen angel investments, approaching them less as a conventional portfolio and more as a way to support people and ideas he believed deserved a chance.
“These aren’t investments you make on a Monday and see the outcome on Friday,” he said. “It takes a while for them to pay off.”
The same could be said of building a tech ecosystem.
Vancouver’s current strength did not emerge from one company, founder, or funding announcement. It was accumulated over decades as global companies established local offices, employees gained experience, founders created and sold businesses, and some of the resulting talent and capital flowed into the next generation.
Pilarinos has been part of that process for nearly two decades, even if he has rarely called attention to it.
“It’s easy to sit on the sidelines,” he said. “It’s another thing entirely to go and build companies here.”
