Webtmize | Montreal, Quebec | Performance Marketing for E-Commerce and SaaS
There is a particular kind of pressure in performance marketing that most agency work does not carry.
A brand agency delivers a campaign and the client judges it on whether it feels right. A performance agency spends the client’s money in real time, every day, and at the end of the month there is a number. Either the return justified the spend or it did not. Nobody has to interpret it.
Webtmize managed fifty million dollars of client media spend last year, across more than fifty active clients globally and over two thousand projects delivered. That is the scale at which the discipline stops being about clever tactics and starts being about infrastructure.
The Montreal agency describes itself in four words that read like an operating principle rather than a tagline: powered by performance, driven by data.
A Technologist’s Agency
The company’s character makes considerably more sense once you know where its founder came from.
Abdo Mazloum graduated in computer science and began his career as a web developer at an SEO agency. He went on to work as an SEO specialist at SSENSE, the Montreal-based global fashion e-commerce platform, where he applied analytical rigour to maximizing traffic at genuine scale, and later led paid search, organic search and programmatic media as a senior executive at another agency — including a seat on an exclusive Google Premier Partners advisory council.
After roughly a decade across both agency and client sides, he took Webtmize seriously as a business, hiring his first employee at the start of 2018 and opening an office that September.
That trajectory — developer first, marketer second — shows throughout the firm. Most agencies treat data as reporting: a monthly deck summarizing what happened. Webtmize treats it as infrastructure, and the service list reflects that. Alongside paid search, paid social and programmatic media buying sit data analytics, data science, and reporting and automation as distinct practices.
The firm’s own framing of why that matters is nicely unpretentious: you don’t have time to read all those reports, so we make sense of the numbers for you.
The engineering instinct extends to the tools the agency publishes freely — an advanced ROAS and profit calculator, a keyword merger, and Pulse, a GA4 audit and data-quality dashboard. That last one is telling. Data quality is the least glamorous problem in digital marketing and the one that quietly invalidates the most decisions. An agency that builds a monitoring tool for it is an agency that has been burned by bad measurement and decided to fix the cause.
Web development, Shopify development and web integration round out the offering, which means the agency can repair the landing page rather than just report that it is underperforming.
Who They Work With
The client roster is a good indication of the level the firm operates at: Browns Shoes, Mackage, Linen Chest, Pajar, WSP, Soha Nuts, PNP, Yeti, Isaac Mayer Fine Jewelry and Bioderma, among others.
These are established retail and consumer brands with real media budgets and real accountability — not businesses that will accept impressions as evidence.
The client testimonials converge on a single phrase, which is unusual and worth noting: repeatedly, clients describe the team as an extension of their own company. A director of e-commerce at Browns Shoes calls the engagement one of the best decisions he made in the role. A client at Nuknuuk describes surpassing growth targets across email, ads, SEO and web development together.
That last detail points to something structural. The agency sells channels separately, but its clients experience them as one system, which is the only way performance marketing actually works — paid search and SEO competing for the same query, email retaining the customer that advertising acquired, the website converting or losing all of it.
The partner credentials support the work: Google Premier Partner status, membership in Google’s International Growth Program, and partnerships across the commerce stack including Shopify and HubSpot. In 2022, Google Canada selected Mazloum as the only marketing agency leader invited to speak at its inaugural Think Global Export Summit, in a fireside chat alongside the CEO of Clearco and the CMO of FreshBooks.
The agency operates fully in English and French — table stakes in Quebec, and a genuine asset for brands selling into both markets.
What Comes Next
Webtmize has moved early on the most consequential shift in search since paid ads arrived.
The agency now offers AI and GEO — generative engine optimization — as a named service, addressing what Mazloum has described as the transition from search engine optimization to answer engine optimization. When a customer asks an AI assistant which winter coat to buy rather than typing the query into a search box, the mechanics of being discovered change completely. There is no results page to rank on, no click to measure in the familiar way, and the sources these systems draw from behave differently from traditional search signals.
Most agencies are still describing this as a future concern. Webtmize has built a practice around it and is publishing on the methodology.
For e-commerce and SaaS brands whose growth depends on being found, that is the right thing to be early on. And it is a natural fit for an agency built by someone who came to marketing through code — because this shift, more than any before it, is a technical problem before it is a creative one.
The number at the end of the month is still the number. What changes is what has to happen upstream to move it.
