Meet the Mind Behind Your Financial Future
At harmonexyvia, we believe financial planning isn't just about numbers – it's about understanding the person behind those numbers. Our team-first approach means you're not just getting advice, you're getting a dedicated partner in your financial journey.

Declan Hartwell
Senior Financial Strategist
The Story Behind the Strategy
Declan didn't start his career thinking he'd become a financial planner. After completing his economics degree at Griffith University in 2018, he actually worked in data analytics for a mining company. But watching his colleagues struggle with basic financial decisions – despite earning good salaries – made him realise something was missing in how we approach money management.
The turning point came when a colleague asked him to help review her superannuation options. What should have been a straightforward conversation revealed just how disconnected most people feel from their financial futures. "She was brilliant at her job, understood complex geological surveys, but felt completely lost when it came to choosing between investment options that would affect her for decades," Declan recalls.
"I realised that financial planning isn't really about being good with numbers – it's about being good with people. The best strategy in the world means nothing if it doesn't fit how someone actually lives their life."
That insight shaped everything about how harmonexyvia approaches financial planning. Rather than starting with generic advice or one-size-fits-all solutions, we begin by understanding your specific situation, your worries, and what success actually looks like for you. Declan's background in data analysis means he can crunch the numbers, but his real strength lies in translating complex financial concepts into practical, actionable plans that make sense for real life.
Since joining harmonexyvia in early 2022, Declan has helped over 200 Australian families navigate everything from first home purchases to retirement transitions. He particularly enjoys working with people in their 30s and 40s who are juggling multiple financial priorities – because he knows firsthand how overwhelming that can feel.
Our Journey to Better Financial Planning
harmonexyvia Founded
Started with a simple mission: make financial planning accessible and personal. We noticed too many Australians were either avoiding financial planning entirely or getting generic advice that didn't fit their actual lives.
Research-Driven Approach
After working with our first 50 clients, we identified the biggest gap: people needed to understand the 'why' behind financial decisions, not just the 'what'. This insight completely changed how we structure our planning process.
Milestone Planning Framework
Developed our signature milestone-based approach after realising that traditional age-based financial advice often missed the mark. Life doesn't happen in neat decades, and neither should your financial planning.
Expanding Our Impact
Now serving families across Australia with personalised financial strategies. Our focus remains the same: helping people make confident financial decisions that align with their actual goals and circumstances.
Evidence-Based Planning
Every recommendation we make is backed by research and data analysis. We don't believe in financial planning based on gut feelings or trends – your future deserves strategies grounded in evidence.
Goal-Focused Strategy
We start with your specific milestones and work backwards to create a plan. Whether you're planning for a home deposit, career change, or retirement, your goals shape every aspect of your financial strategy.
Partnership Approach
Financial planning is collaborative. We provide expertise and analysis, but the decisions are always yours. Our job is to ensure you have all the information you need to choose confidently.
