VAIDA’s Proprietary Methodology

“Fund managers no longer have to make decisions in the dark.
Our attribution analysis unlocks deeper insights, empowering smarter and faster decision-making.”
— Andy Buchan VAIDA CEO

The Origin of VAIDA.

In the world of funds management, where precision and foresight determine success, gaining a competitive edge isn’t just about having the best data—it’s about understanding that data in ways others can’t. This is where VAIDA’s Valuation Attribution Analysis stands apart. But to truly appreciate the power behind VAIDA’s proprietary approach, you need to know the people who built it.

The Architect

At the heart of VAIDA’s innovation is Andy Buchan, a name synonymous with excellence in real estate financial modelling and data-driven analytics. With over 25 years of hands-on experience across Australia’s top-tier investment institutions, Andy has mastered valuation methodologies and developed proprietary performance analytics, forecasting, and modelling techniques that are unmatched.

His career includes influential roles at ISPT (Industry Super Property Trust) and AWARE Super, where he revolutionised fund modelling, portfolio analysis, and forecasting. The models he created didn’t just measure past performance—they predicted market shifts, giving fund managers a forward-looking advantage in volatile conditions.

Beyond building tools, Andy has trained and mentored a generation of Australia’s most successful fund managers and analysts. His focus on disciplined, data-driven decision-making has shaped leaders who can interpret complex information and turn it into strategic advantage.

The Strategist

Joining Andy in shaping VAIDA’s foundation is Amélie Delaunay, an internationally recognised leader in real estate research and analytics across the Asia-Pacific. As Senior Director for Research & Professional Standards at ANREV, Amélie oversees cutting-edge market intelligence programs, performance measurement indices, global surveys, and professional standards for the region’s largest investor network.

With more than 20 years in the real estate sector, including nearly two decades living and working in Asia, Amélie’s experience spans global consulting at Ernst & Young to setting the benchmark for industry data and reporting standards. Her academic credentials—postgraduate degrees in urban geography, town planning and real estate from the Sorbonne, and advanced real estate management from ESSEC Business School—give her a rare blend of analytical precision and strategic insight. As a professional member of the Royal Institution of Chartered Surveyors, she is a trusted voice on capital market dynamics, ESG integration, and transparency in reporting.

The VAIDA Advantage

When Andy founded VAIDA, his vision was not to build another valuation tool, but to transform how data is used to create value. With Amélie’s global research leadership and Andy’s precision-built analytics, VAIDA’s Valuation Attribution Analysis framework captures the nuances that generic models miss. It combines deep market expertise with robust, forward-looking analytics, giving clients the ability to see what others can’t—turning complex valuation data into actionable strategy.

Together, Andy and Amélie have created more than a platform. They have built a methodology rooted in decades of specialist experience, tested in the world’s most competitive investment markets, and proven to give fund managers a decisive edge.

Unique Calculation Methodologies Rooted in Real-World Experience

  • Granular Understanding of Market Movements: Andy’s models account for sector-specific variables, geographical nuances, and asset-level dynamics—offering a level of granularity that generic models cannot replicate.

  • Adaptive Frameworks: Unlike traditional models that rely on static formulas, VAIDA’s Valuation Attribution engine adapts to evolving market conditions, ensuring accuracy even in volatile environments.

  • Millions of Data Points, Processed in Real Time: VAIDA’s models analyze vast amounts of structured and unstructured data, identifying insights that would take human analysts months to uncover.

Looking Beyond Historical Data

Traditional valuation models are like rear-view mirrors—they show you where you’ve been but offer limited insight into where you’re going. VAIDA flips this paradigm by combining historical data with real-time market indicators to forecast future valuation shifts with unprecedented precision.

  • Market Trend Analysis: VAIDA’s models identify early warning signals, allowing fund managers to adjust strategies before market conditions change.

  • Scenario Testing and Sensitivity Analysis: Fund managers can simulate multiple market scenarios, empowering them to assess the impact of potential shifts on their portfolios.

The Future of Unlisted Asset Management

  • Accuracy: Proprietary models built on 25 years of real-world expertise giving valuation outputs that are precise and trustworthy.

  • Transparency and Confidence: Every data point and calculation is traceable, giving decision-makers the confidence to act decisively.

  • Actionable Insights Beyond the Numbers: VAIDA’s predictive engine doesn’t just tell you where the market is—it shows where it’s headed, giving you a strategic advantage in portfolio management.
