How Wealthsimple Actually Builds: Inside the Day They Took Over Your Life
A recap of May 21st's Calgary Tech Thursday session, co-hosted with Wealthsimple, featuring Sam Newman-Bremang, Jocelyn Jeffrey, and Channing Allen.
A few hours before our panel started, Wealthsimple held a press event in Calgary called Wealthsimple Takes Over Your Life. They announced a suite of household and small business banking products, a Kids and Teens account, and a handful of other tools that quietly expand what Wealthsimple is. By the time the audience sat down at 5 PM, the announcement was already public.
Our job, instead of introducing the products, was to get inside the room where they got built.
The panel featured:
Sam Newman-Bremang, Sr. Director of Product at Wealthsimple
Jocelyn Jeffrey, Director of Engineering at Wealthsimple
Channing Allen, Sr. Engineering Manager at Wealthsimple and former Co-Founder of Plenty
This is our recap of the top ideas from the conversation.
“We could literally not pay people to use a banking product at Wealthsimple. But we persevered.” Sam Newman-Bremang

1. The Arc From Investing to Taking Over Your Life
The takeaway: Wealthsimple’s expansion from an investing product to a full financial life platform took five years of work that started with most people refusing to use the banking product. The momentum looks inevitable from the outside. From the inside, it was anything but.
Sam joined Wealthsimple five years ago. When he started, the company was an investing platform. The banking thesis was held by what he described as a small group running around campuses giving away bubble tea and trying to get people to download an app. It didn’t work. They couldn’t give it away.
The pivot came from listening. People didn’t want a Venmo for Canada. They wanted an alternative to their bank. Direct deposit. Bill pay. Interest. Wealthsimple built that, and the banking product is now a million-client business with $10 billion in cash and payment volumes in the billions.
Today’s announcement, in Sam’s framing, is the same arc continuing. Business chequing, household money management, and Kids and Teens accounts all build on the operating muscles developed during the banking expansion.
Why this matters: The companies that survive long enough to expand their scope this dramatically tend to share one thing in common, which is that the early scope was earned the hard way. The campus bubble tea era of Wealthsimple isn’t a footnote in the story. It’s the foundation.
2. How Wealthsimple Actually Builds
The takeaway: A nine-person engineering team can ship Kids and Teens accounts, Spend Insights, and household money management in parallel if you structure the work around small squads, embedded design, and a value the company calls naive ambition.
Channing’s team is nine engineers, organized into two-to-four-person squads, each working on a different product simultaneously. The Kids and Teens accounts, Spend Insights, and Households all came out of that nine-person org operating in parallel. The mechanism that holds it together is ownership at the individual level. Engineers take Directly Responsible Individual (DRI) ownership of projects within their workstream, including the technical design, the implementation, and the outcomes after the product ships.
Sam credited the culture itself, not the structure, with making the cross-functional model work.
“One word that comes to mind for me is humility. You’re bringing three people together with different perspectives, and you need to be humble that you don’t have the answer.” Sam Newman-Bremang
The cultural mechanism that powers the ambition side is something Wealthsimple calls naive ambition. The clearest example came from the same morning’s announcement. The $25,000 e-transfer limit Wealthsimple shipped this week started with the team deciding Canadians should be able to move their money without limits, before they were even legally allowed to send an e-transfer. To make it real, they became an Interac member, talked to politicians, and rebuilt the partner stack. The output was a single product launch. The input was naive ambition operationalized.
Wealthsimple also runs a structural ritual called Go Days. Three to five days where the entire team for an ambitious outcome gets in a room together, with schedules cleared. Channing described one recent example.
“We started the beginning of the week with zero lines of code written and a really derpy prompt that I had put together. By the end of three and a half days, we had a working end-to-end prototype shipped in production that we were able to use internally.” Channing Allen
Why this matters: A lot of companies have read the same books about small teams, ownership, and design-engineering collaboration. Wealthsimple’s version works because the culture values humility and ambition simultaneously. Those two things sound contradictory until you’re in a room where someone says “we should just let Canadians move their money without limits” and the engineers don’t roll their eyes.
3. AI in the Workforce, and Why They Cancelled Cursor
The takeaway: Wealthsimple has shifted nearly all of its AI engineering work onto Claude, including agentic workflows that operate outside the traditional Integrated Development Environment (IDE). The shift is changing not just how engineers work, but what the role itself looks like.
Jocelyn went on maternity leave in January 2025 and returned in January 2026. The 12-month gap turned out to be the perfect natural experiment.
“I came back to work and I was talking to a colleague, and I was like, ‘It seems like most things are the same.’ And they were like, ‘Yeah, we just don’t write code anymore.’” Jocelyn Jeffrey
She came back into a Claude world that did not exist when she had left. The Cursor cancellation, which we asked about explicitly, was tied to a broader shift she and Channing both described as moving past IDE-with-AI into fully agentic workflows. Cursor was the last traditional IDE. Claude Code, in their telling, is the new paradigm.
The team has been seeing pull request cycle times cut in half.
Channing extended the point to what this means for the engineer’s role. Code generation marginal cost is going to zero. Code review becomes more important. The ability to deeply understand the system you’re operating in becomes the moat. The ability to give a good prompt becomes a skill. System design, for younger engineers, becomes the area to invest in.
For PMs, the shift has been just as significant. Sam now expects every product manager to be able to query the data themselves, read the code base, and operate as a real-time analyst. The data scientist as bottleneck is mostly gone.
Why this matters: Most of the engineering organizations we talk to in Canada are sitting in the middle of an AI tooling conversation, weighing whether to expand or hold. Wealthsimple has already crossed over. They’ve cancelled the Cursor subscription, gone all in on Claude, restructured their expectations of every individual contributor, and built rituals around the new reality. The pace at which they shipped today’s announcement is partly downstream of that decision.
A Few Takeaways for Builders
Surveys give you signal, not answers. The 1,700-client survey behind the household product told Wealthsimple where the problems were, not how to solve them.
Multifaceted teams only work with humility. Wealthsimple’s product-design-engineering collaboration works because of who they hire.
Naive ambition isn’t a slogan if you can name an example. The $25,000 e-transfer limit started with “we should just let Canadians move their money” before they were legally allowed to.
Going vertical in the stack pays for the low-cost operating model. Wealthsimple is the first non-bank credit card issuer in Canada. They have accounts at the Bank of Canada. The fees stripped out by removing middlemen are what fund 2% cashback and 2.25% chequing interest.
A massive thank you to Channing, Jocelyn, and Sam for being so generous with their time, and to the broader Wealthsimple team for co-hosting the evening with us in Calgary.
