Dave Whittle and the art of making data human

At an early Australian Twitter meetup, Dave Whittle made an impression before he made a business connection. Aaron Wallis remembers a tall figure dressed in Dolce & Gabbana among the technology enthusiasts. Wallis went over to talk. Within a month, he was working for Whittle. Years later, they would be building Lexer together. The internet had arranged an introduction. The clothes had done some useful targeting.

There is something pleasingly untidy about this beginning. A company concerned with customer information and useful connections has a founding relationship that started with curiosity at a gathering. No elaborate selection process appears in the anecdote. Two people met, talked and discovered enough common ground to take the next step.

Whittle’s subsequent career has made that encounter look less accidental. He moves between commercial and technical worlds, interested in what happens when different abilities share a purpose. His working life includes early digital advertising, leadership at M&C Saatchi, software entrepreneurship and seats on public-company boards. The titles change. The question of how people work together keeps returning.

Two ways of seeing

Whittle is the son of an artist and a scientist. He has connected those parental influences to his interests in creativity and analytical thinking. It is an unusually economical explanation for a career that can otherwise look like several careers sharing a calendar.

At Deakin University, he studied arts and commerce. The combination gave formal expression to those different interests. His early professional experience then placed him in an industry where the relationship between communication and technology was being worked out in public, with clients paying to discover what the internet might become.

In 1998, he was working in client services at Blue digital. He has described being the first employee of Australia’s first digital media buying agency. His early ventures also included Trafion Technologies. This was an education in building businesses around a medium whose commercial conventions were still being invented.

“I commercialise creativity.”

Dave Whittle

The phrase leaves room for both invention and responsibility. An idea has to survive contact with a budget, a customer and a deadline. Equally, a set of figures needs someone able to imagine a useful response. There is room for an artist and a scientist at this desk, provided they can agree on what to deliver.

That tension gives his career its particular shape. Advertising rewards the ability to make something intelligible and memorable. Software asks whether the same useful operation can be performed repeatedly. A director must consider what the business is committing itself to. Moving between these settings changes the scale of the decision while preserving the need for judgment.

A business that could outlast the brief

Whittle spent ten years with M&C Saatchi, including three as managing director in Australia. He helped establish and grow its digital business across Asia Pacific and the United States. The work put technology inside a larger advertising organisation, where technical capabilities had to make sense to people buying campaigns and building brands.

That is a demanding translation job. A client needs to understand what a capability can achieve before becoming interested in how it works. An agency also has to deliver what it has sold. The commercial and creative halves of the conversation have to remain close enough to hear each other.

Lexer offered Whittle a different way to build. He has described wanting a software business that could scale and retain value over time. Agency experience supplied both the problem and some of the people who could work on it. Wallis brought the technical craft; Whittle brought commercial relationships and a willingness to put the product in front of customers.

One early relationship captures the division of labour. Wallis had struggled to reach Qantas. Whittle called Paul Smitton there and arranged a meeting. The airline became an important customer. In Wallis’s recollection, the ease of the introduction was both irritating and welcome. A colleague with the right phone number can be an excellent corrective to a difficult week.

For someone moving out of advertising, that also changes what success looks like. The pitch can open a door, but the product has to justify another month, another year and another renewal. Commercial relationships remain valuable because they create opportunities to learn. The learning still has to reach the software. A founder who can hear both the customer’s request and the developer’s explanation occupies a useful place between them. That position demands more than fluency in the vocabulary of each group. It requires decisions about which problems deserve the team’s time.

The underlying choice was to pursue large customers early. Serving an enterprise places demands on a young product and on the people responsible for it. It also puts the founders close to complicated, consequential problems. Whittle has explained that Lexer’s approach was to develop that capability first, then make it available more widely.

The customer behind the spreadsheet

By February 2021, Lexer had announced an AU$33.5 million Series B, taking its disclosed funding at that point to AU$43 million. Blackbird and King River Capital led the round, with January Capital participating. Whittle was CEO. The announcement set out plans for product development and 50 additional team members over the following year.

The customer problem was fragmentation. Businesses could accumulate information about shoppers without having an accessible picture of the relationship. A purchase in one place and an interaction somewhere else might sit in separate systems. Having more records did little for a team unable to connect them and decide what to do.

Lexer’s retail customer data platform brings that information together for analysis and action. Its offering includes tools and support for the people using them. The practical test is what changes for a retailer and its customers: better understanding, more useful communication and less time spent wrestling with disconnected information.

A platform diagram can make this look wonderfully tidy. The person at the other end experiences something more ordinary: whether a business remembers a purchase, understands a preference or sends a useful message. That modest experience is where the technology earns its place. Customers are under no obligation to admire the plumbing.

Whittle’s public language about Lexer repeatedly returns to people. “That human touch is really important,” he has said. The commercial promise depends on a business using information with some understanding of the customer it describes. A profile in a database becomes valuable through the quality of the decisions made with it.

A smaller table, a wider view

Whittle’s interest in complementary people extends to governance. Discussing startup boards in 2021, he argued for a useful mix of experience and a board sized appropriately for the business. At that time, he described Lexer’s board as three co-founders and two major investors.

The point is practical. Each additional person changes the conversation. A board should supply perspective, challenge and help, while remaining able to make decisions. An impressive guest list can still produce a poor meeting. The useful question is what each person contributes to the work the company actually faces.

His own board career has moved through businesses with substantial customer relationships. He served on Myer’s board from 2015 to 2024, joined Michael Hill International in August 2023 and joined Metcash in November 2024. Challenger added him as an independent non-executive director in June 2025. These appointments bring his experience into retail, distribution and financial services.

Metcash’s appointment announcement specifically connected his background to customer loyalty, brand and the application of data. It also described him as a former Lexer CEO. Lexer now lists him as CCO and co-founder, with David Chinn as CEO and co-founder. His work has continued to evolve beyond the title attached to earlier funding announcements.

Plain text, real people

One of Whittle’s public product arguments begins with the messages people read first. He points to ordinary exchanges with friends and family, then uses that familiar behaviour to explain Lexer Contact. The product lets business teams communicate with customers, informed by data and assisted by AI-generated content.

The explanation fits his advertising background. Begin with an experience someone recognises. Give the technology a purpose within it. Plain text makes a revealing choice of example: after all the effort involved in assembling the information, the result might be a simple message that makes sense to its recipient.

There are less digital interests, too. A biography credited to Lexer describes skiing, cycling and growing vegetables. They are agreeable counterweights to a career spent discussing information and communication. A vegetable garden supplies its own fairly direct performance reporting.

In his August 2025 appearance on The First, Whittle returned to co-founder trust, shared vision and the importance of choosing people carefully. He discussed humor as a sign of intellect and advised founders to start early, accept the possibility of failure and release their egos. The advice allows for uncertainty without surrendering the ambition to build.

That brings the story back to the meetup. The striking outfit makes the anecdote memorable. What gives it weight is the working relationship that followed. Across agencies, software and boards, Whittle’s career keeps finding its shape through collaborators: people with different abilities, enough trust to disagree and something useful they want to make together.
