Michael Strickman Built the Recommendation Engine Before He Bought the Traffic

Before leading Xero's global marketing, Michael Strickman spent years teaching software to narrow choices, measuring demand at Tripadvisor and scaling performance marketing at Uber. His career is a study in how technical judgment becomes commercial judgment.

A useful way to read Michael Strickman's career is to follow the noise. In the early internet, the noise was an overstuffed shelf of movies, music, products and pages. At Tripadvisor, it became a torrent of searches and visits. At Uber, it arrived as demand moving through thousands of local markets. At Xero, it is the daily complexity of running a small business: invoices, bank feeds, payroll, expenses, accountants, apps and the stubborn shortage of time.

Across those settings, Strickman kept working on the same practical problem. How do you notice what matters inside a mass of behavior, then make the next decision easier? The answer has taken him from code to campaigns and from a startup CTO title to the chief marketing officer's seat at a global accounting software company. The tools changed. His instinct for systems did not.

That makes him an unusual marketing executive. His formal training was a Bachelor of Science in Applied Mathematics, earned with honors from Brown University in 1983. He later became a technology founder, not a copywriter climbing an agency ladder. By the time online businesses began treating personalization as table stakes, he had already spent years trying to make it work.

Before the feed, there was the choice

ChoiceStream, which Strickman co-founded around 2000, belonged to an earlier and more explicit age of personalization. The company worked on software intended to narrow choices to the few that mattered, using preferences and behavior to improve recommendations. A published patent application for a statistical personalized recommendation system lists Strickman and Jayendu Patel as inventors and claims an earliest priority date in August 2002.

The phrasing in those old systems can sound dry: users, items, ratings, parameters. The commercial promise was anything but. An online store did not have to give every visitor the same experience. It could adapt. It could notice. It could rank. Long before a personalized feed became the default window into the internet, ChoiceStream was wrestling with the machinery underneath that idea.

“There's a huge amount of noise in raw clickstream data.”Michael Strickman, during his ChoiceStream years

That sentence has aged well. A click is visible, countable and often ambiguous. It can represent interest, confusion, habit or an accidental thumb. Strickman's early observation was not an argument against data. It was an argument for treating data with judgment. Useful information could come from observed behavior, but also from asking people what they wanted. Measurement needed context.

The builder learns to buy demand

Strickman's next chapters put the model into faster, larger markets. At Tripadvisor he served as vice president of traffic acquisition and measurement, leading global demand generation. Travel search is a laboratory for intent. A destination can begin as a daydream, become a comparison exercise and end as a booking. Each step produces data, but the steps do not carry equal meaning. His title paired the act of acquiring attention with the discipline of measuring it.

At Uber, where he became vice president of performance marketing and growth, the problem gained a physical dimension. Demand was not one global pool. A ride requested in Boston could not be fulfilled by a driver in Brisbane. Growth depended on timing, location and a marketplace's local balance. Performance marketing in that context was not simply the purchase of clicks. It interacted with an operating system of cities.

The progression is neat but not tidy. Startup technology, travel discovery and urban mobility each carry different customer habits. What connects them is the need to distinguish visible activity from genuine intent. A metric can tell a team what happened. The harder work is deciding why, what the customer was trying to do and which intervention would help.

There is also a change in the unit of analysis. ChoiceStream considered the individual and a catalog. Tripadvisor added the journey, with curiosity gradually becoming intent. Uber added a live marketplace whose conditions could change block by block. Every move made the feedback loop faster and the consequences of a weak assumption more visible. By the time Strickman reached an executive marketing brief, measurement was not a report delivered after the work. It was part of how the work was designed.

At Xero, the product is somebody's Monday

Xero hired Strickman in October 2023. His remit is broad: direct customer and partner marketing, plus alignment across brand, marketing, digital and communications around the world. He is charged with growing the company's reputation and deepening its connection with customers and communities. In public, he described Xero as a key financial engine for small businesses and the accountants and bookkeepers who support them.

“Financial engine” is revealing language. Accounting software can be described as a list of features, but the customer experiences it as motion or friction. An invoice is revenue waiting to arrive. A bank reconciliation is confidence that the picture is true. A clean collaboration with an accountant is one less late-night email. A useful campaign has to translate software architecture into those ordinary moments.

The partner dimension complicates the work. Xero speaks to business owners, but also to accountants, bookkeepers, financial institutions and an ecosystem of connected applications. These groups do not share one vocabulary or one purchase path. Brand creates a common promise. Performance marketing finds people close to action. Partner marketing reaches them through trusted professional relationships. Communications makes the whole arrangement understandable.

The bars are not performance scores. They show the different jobs sitting inside one title. The difficult part is alignment. Customers do not care which internal team authored a message. They notice whether the promise in an ad resembles the product they open, whether a partner can explain the value and whether the company sounds consistent when circumstances change.

A public style built around other people's work

Strickman's public footprint is measured. When he announced the Xero role, he paired excitement about growth with a desire to learn the team and Xero's culture. The list of colleagues in that post mattered. It framed the assignment as collective work across leadership rather than a solo arrival.

Soon afterward, he highlighted the winners of the Xero Beautiful Business Fund, a program that asked small businesses to describe their work and aspirations in short videos. His invitation was to watch the owners themselves. Their stories, he wrote, showed both the innovation inside the small-business community and the effect a platform could have in facilitating it. The marketer stepped aside and pointed toward the customer.

“I'm looking forward to getting to know the entire team and Xero's unique culture.”Michael Strickman, announcing his Xero role

That posture fits the long arc. Personalization begins with the admission that different people want different things. Measurement begins with the admission that intuition is incomplete. Partner marketing begins with the admission that a company does not own every customer relationship. Each discipline asks the executive to pay attention before speaking.

What the career teaches

The obvious lesson is that technical fluency can travel. Applied mathematics did not confine Strickman to a research function. A CTO title did not prevent a move into traffic acquisition. Performance marketing did not prevent responsibility for brand and communications. Each transition widened the system he had to understand.

The more useful lesson is about restraint. Data is powerful because it reduces uncertainty, not because it eliminates judgment. A dashboard can rank channels while missing the reason a customer trusted the message. A recommendation can optimize a click while narrowing the world too aggressively. A campaign can acquire an account while saying little about whether the owner found lasting value.

Strickman's work sits at that boundary between calculation and interpretation. His early career asked software to make a relevant choice. His later career asks organizations to do the same: allocate attention, decide which customer problem deserves emphasis, and connect a global platform to a local working day.

At Xero, the aspiration is practical. Help small businesses and their advisors thrive. Grow the reputation. Deepen the connection. Those verbs are not as tidy as a conversion rate. They require repeated evidence across product, service, community and message. For someone who has spent a career finding signal in noisy systems, that may be the most interesting measurement problem yet.
