Prophet appoints two senior hires as enterprise business grows

Australian decision intelligence platform Prophet has appointed Lachie Trembath and Tong Wang to newly created senior roles as it expands its decision science and engineering capabilities.

Trembath joins as Senior Marketing Science Partner, while Wang has been appointed Senior SysOps Engineer. The appointments follow growth in Prophet's enterprise customer base, with the company adding clients including Endeavour Group and Kraft Heinz.

New roles created

Trembath will work with enterprise customers to help interpret Prophet's modelling and apply insights to commercial decision-making. Wang will focus on cloud infrastructure, platform reliability, automation and supporting the company's multi-region platform rollout.

Before joining Prophet, Trembath spent almost four years at Analytic Partners, most recently as Senior Marketing Science Analyst. Wang previously held engineering roles at Block, MYOB and Design Industries.

Prophet Head of Decision Science Rachel Scott said:

“Lachie brings deep expertise in marketing effectiveness, econometric modelling and commercial measurement to our team.

“His appointment strengthens both the technical capability and customer partnership side of our Decision Science division. Our clients increasingly want partners who can help them apply model outputs to real decisions. Lachie has a track record for translating complex modelling into practical business decisions, and significant experience working with large enterprise marketing teams, making him a good fit to support our growing customer base.”

Trembath said:

“As more organisations adopt Prophet’s unique digital clones to simulate commercial decisions before budgets are committed, demand has grown for experienced marketing scientists who can help customers interpret results, design experiments and apply insights across the business.

“I’m looking forward to partnering with Prophet customers throughout their decision-making journey, helping them understand how their digital clone works, identify opportunities for optimisation and build confidence in the commercial decisions they make.”

Supporting platform expansion

Prophet Head of Engineering Matthew Winter said Wang's appointment would support the company's growing infrastructure requirements.

"Every Prophet customer runs on their own isolated infrastructure. That's a real differentiator for security and performance, but it also means our operational standards have to rise with every customer we onboard. Tong is exactly the engineer that challenges these demands. He automates rather than firefights, and he treats reliability and security as engineering problems, rather than checklists. This is a growth hire, and it strengthens the foundation everything else is built on.”

“Tong brings extensive experience operating Kubernetes environments at scale, together with an automation-first approach to infrastructure engineering. His background in cloud infrastructure, platform reliability and automation makes him an ideal fit for supporting that growth.”

Wang said:

“I’m excited about the opportunity to join Prophet, particularly as it continues to scale globally. I enjoy building and operating highly available cloud platforms, automating infrastructure and improving operational efficiency. Joining a team solving these challenges at scale aligns with my experience and expertise. I’m looking forward to supporting the wider Prophet engineering team, allowing them to focus on product development, while the platform underneath scales in confidence.”

Prophet said it now works with more than 40 brands across multiple industries and has continued to expand its team across engineering, sales, marketing and decision science since launching in 2024.
