Trusted, hands-on financial due diligence and advisory for SMEs and mid-market businesses in Singapore and Malaysia. Senior-led, personally delivered — every engagement.
Rooted in strength, flowing with foresight.
You work directly with an experienced advisor — not a junior analyst running a template.
Transparent scope and pricing before we start. No surprises, no inflated retainers.
Most clients come back. We aim to be the advisor you call first — for years, not just once.
We start where most businesses need us most — financial due diligence. As trust grows, many clients ask us to stay on for broader advisory, transformation and performance work.
Whether you are buying, selling or preparing for investors, we give you a clear, honest picture of the financials — so you can make decisions with confidence.
Helping you prepare for a transaction, raise capital or engage with PE investors — from first conversation to completion.
When the deal is done or the investor is in — building the finance infrastructure and performance visibility the business actually needs.
30 minutes, no charge. We listen to understand your situation and tell you honestly if we can add value.
A written scope, timeline and fee — agreed before anything starts. No ambiguity, no surprises.
We get into the detail directly. Senior involvement throughout — not handed off to a junior.
Clear deliverables, plain-language findings and practical next steps — not just a report that sits in a drawer.
We work best with owners and management teams who know the numbers matter — and want someone senior in their corner when it counts.

Oakstream Advisory is founded by a Chartered Accountant with 15+ years of experience across M&A advisory, listed-company CFO and Finance Director roles in Singapore and Malaysia.
The practice brings together a career advising on 30+ transactions for PE funds, multinationals and strategic investors across Southeast Asia — with the practical experience of having run finance inside complex, fast-growing businesses. Having sat on both sides of the deal table — as the advisor and as the operating CFO — we understand what investors look for, and what businesses need to be ready.
We work with a small number of clients at any one time. That means you always get genuine senior attention — not a team that's stretched thin across dozens of mandates.
Good financial advice should feel like a trusted conversation, not a formal report.
A complimentary 30-minute call for all new enquiries. No commitment, no sales pitch — just an honest conversation about whether we can help.
We respond to all enquiries within 1 business day. For anything urgent, please call or WhatsApp directly.
