Who we are
Helping clients build,
protect and preserve
lasting prosperity
Addsum helps people and businesses build, protect and pass on wealth across borders: through judgement, sincerity and long-term purpose. We combine professional rigour with deep cross-cultural fluency to act as a second layer of judgement, ensuring decisions aren’t just efficient – they’re also right.
Many of our earliest clients are still with us today. That continuity reflects how we work – long-term, relationship-first and focused on outcomes, not just transactions.
Why Addsum?
Trust across
borders
Most professional services firms can offer technical capability or personal relationships. Addsum was built to provide clients with both.
We combine the institutional-grade expertise of a top-tier firm with the cultural understanding and independent judgment that come from three decades of experience within the Asia-Pacific community.

FAQ
Have a question?
We have answers.
We’re built from within the Asia-Pacific community we serve. That means we understand not just the technical and regulatory environment, but the relationships, values and decision-making styles behind it.
Yes. Our client base spans the Asia-Pacific – including China, Hong Kong, Singapore, Malaysia, Indonesia and the Philippines – and we regularly advise on cross-border structures, investment, tax planning and family wealth that spans multiple jurisdictions.
Many of our clients use Addsum to complement and supplement the advice they receive from Big Four accounting firms. While the Big Four handles scale, we provide the cross-border advisory, coordinated guidance and independent judgment that larger firms, by their nature, cannot offer.
Yes. We advise HNW individuals and families on wealth management, intergenerational planning and the personal financial decisions that sit alongside their business interests.
If your business, investments or family interests span borders, you’ll benefit from advice that understands and considers the full picture. We’re always happy to have an initial conversation to see if there’s a fit.
