Siong Yoong M&A adviser Expert witness

Recognise him? You fund what you recognise.

I advise on M&A, valuations and due diligence, and I have given evidence before the Supreme Court of Singapore. Since 2007 I have sat in the three seats a deal passes through: building the company, selling it, and judging it when it is disputed.

The Business Times
The belief

The founder you passed on looked nothing like you. The evidence was in the deck.

An investor trusts the founder who feels familiar, the school, the path, the way of talking, and calls that familiarity judgment. I have read founders across deals since 2007. Each week in Unrecognised I read one founder investors did not recognise, and what the evidence said.

Straight answers

Questions investors ask.

How do Verdict™ and VALLARIS™ fit together?

They sit either side of a US$10M ARR line. Below it, Verdict™ scores founders and matches them to the investors whose mandate they fit. Above it, a valuation or a due-diligence report has to be signed by a credentialled professional who carries the liability. That is VALLARIS™: an independent M&A and capital advisory studio where a named Chartered Valuer and Appraiser signs every valuation and report.

What is Unrecognised?

My LinkedIn newsletter. Each issue reads one deal: what the room recognised, and what the evidence showed.

Can I book you to speak?

Yes, for investor and professional audiences, on valuation, M&A and how investors read founders. Tell me about the event →
