His story

An engineer who lost money backing startups. Then I learnt what a company is worth.

I advise on M&A, valuations and due diligence, and I have given evidence before the Supreme Court of Singapore. My work is one obsession: value. I created it as an engineer, and I price and fund it as an M&A adviser and venture specialist.

Four stages

Every founder I meet is somewhere on the same road. So am I.

Survival, sufficiency, significance, then paying it forward. My life has run through them in that order, and so has the life of almost every investor I sit across. That is why I read founders the way I do.

  • Survival. The engineer who lost money working in and investing in startups, friends and businesses.
  • Sufficiency. The adviser who learnt what a company is worth, in deal advisory at KPMG, then at VALLARIS™.
  • Significance. The seat in court and on the standards bodies, where my reading of value is tested.
  • Pay it forward. My judgment written into Verdict™'s Scoring Engine, so founders I will never meet are read on merit.

Why two companies

Below US$10M ARR, judgment can be written down. Above it, judgment needs a name on it.

Below the line, my reading of founders is encoded in Verdict™'s Scoring Engine, so founders are scored at scale on what investors actually fund. 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. It stays a separate firm, because independence is the asset and it cannot be shared with the platform that scored the deal.
