Kenyohn Clark.
Founder and CEO of Othello International — the Bangkok firm that couples ISO 17100 certified translation with in-house ESG and carbon methodology. A U.S. Army veteran who built Othello in 2020, he has made it the specialist authority on the disclosure-quality layer of Thailand’s 2026 FTSE Russell / TSRS transition.
Built for the intersection.
Othello began in 2020 on U.S. CDC and State Department translation work and grew into an institutional bilingual firm serving SET-listed corporates, Thai state enterprises, big-law firms and the UN system. Under Kenyohn Clark’s direction it took a deliberate position most firms can’t occupy: the point where certified language meets ESG methodology — where a Thai company’s English disclosure is not translated after the fact, but engineered to earn its FTSE score.
Most recently, his team produced the Thai-language edition of “Building Thailand’s Carbon Pricing Architecture” — the legal and policy assessment of Thailand’s draft Climate Change Act, authored by DLA Piper under the UK PACT programme for the Department of Climate Change & Environment — translating and producing it with certified legal-translation rigour and carbon-market fluency at once.
What he works in.
The firm he built
ISO 17100 certified, with in-house AA1000AS, ISO 14064, GRI, IFRS S1/S2, TGO CFO/CFP, VERRA and CORSIA credentials — an unusual concentration under one NDA and one accountable bench.
The transition he calls
From 2026, FTSE Russell scores SET-listed companies from their public English disclosure. Clark’s thesis — that the English edition, not the Thai filing, earns the score — is the argument the firm is built around.
The record
A FTSE Russell 4.0/5.0 delivered for a SET-listed operator; the Thai edition of a national carbon-pricing policy report; 1,000+ reports for listed corporates since 2021.
