Chris Brewer

CFO & Co-Founder


Chris is a passionate finance professional with 30 years experience across a wide variety of industries.  As CFO of Lexer, Chris gets involved in all manner of things, including numbers, facilities, information security, HR, legal and privacy.  But what he enjoys most is helping the commercial team work with clients and prospects.

Chris is lucky enough to have worked for extended periods in Melbourne, London, Chicago, Milwaukee, Vancouver and Riyadh.  Business is done differently in each of those cities, and a little bit of each is imprinted into Chris’ corporate DNA.

Chris spent 12-years with PwC before accepting a COO role with Tarsus plc, and so began his love of working with technology businesses.  Relocating back to Melbourne in 2003, Chris joined Hitwise and experienced the highs of taking a small Aussie business to a $250m trade sale.  Chris transitioned the Hitwise business to the acquirer before joining Lexer in 2012.

Chris loves golf, wine, cheese, the Brisbane Lions and his family (not in that order). Weekend priority is given to standing in the drizzle at netball and teenage birthday party transportation.

Aaron Wallis

CTO & Founder


Throughout his career, Aaron has always found himself to be either the most creative person in the technical team or the most technical person in the creative team. During his 12 years of experience in industries spanning advertising, design, publishing, startups, and consulting, he ran into a challenge: There was no way to gain real-time insights on the advertising campaigns he was working on with his clients.

Pairing creative vision with technical chops to overcome this challenge, Aaron built and founded Lexer, the Customer Data & Experience Platform helping brands and retailers drive incremental sales through improved customer experiences. Since Lexer’s formation in 2010, he’s built a passionate, dependable team spanning Australia and North America while leading the continued development of both Lexer’s products and culture.

Looking ahead, Aaron’s excited to work with his rapidly-growing team on improving Lexer’s existing solution and exploring the future of data-powered customer experiences. Outside of his work, Aaron is an avid LEGO builder, dedicated dog dad, adventurous cook, and karaoke enthusiast.
