Othello was founded in 2020 in Bangkok. The founding work was translation services for the US Centers for Disease Control and Prevention (CDC) and the US State Department operating in Thailand. The founding story matters because US government translation work is the highest-precision, highest-confidentiality, lowest-tolerance-for-error commercial translation work available. Establishing the firm against that standard on day one set the operating discipline that still governs every engagement today — for Big Law, for SET-listed corporates, for the UN system, and for the ESG advisory practice launched in 2026.

The five intervening years of work — more than 100 annual reports, One Reports, and sustainability reports across SET-listed sectors — produced two things that matter commercially: (1) a Translation Memory asset compounding savings on repeat client programmes, and (2) the substantive familiarity with how Thai listed companies disclose to the world that made the 2026 ESG Advisory expansion a natural evolution rather than a pivot. Founded on precision; grown into advisory.

Othello operates from one office in the Bangkok CBD — Unit 12-03, Chartered Square, 152 N Sathon Rd, Si Lom, Bang Rak, Bangkok 10500, Thailand. The Sathon / Silom location is deliberate: walkable to most SET50 and SET100 head offices, walkable to Bank of Thailand, SEC Thailand, and the Stock Exchange of Thailand, walkable to the major Thai bank headquarters (KBank, SCB, BBL, BAY, KTB), and walkable to most Big Law Bangkok offices. For client engagements requiring confidentiality, in-person work is the default.

The client portfolio runs across six segments: (1) SET-listed corporates across all sectors covered by the Industries practice; (2) Thai SOE issuers (state-owned enterprises) for green bond, SLB, and sustainability disclosure work; (3) Multinational financial institutions (commercial banks, investment banks, asset managers) with Thailand operations; (4) Big Law firms with Bangkok offices (Baker McKenzie, Linklaters, Allen & Overy, DLA Piper, Tilleke & Gibbins and others); (5) The UN system (UN ESCAP, UN agencies operating in Thailand); (6) US government missions in Thailand (the founding client segment, continuing today).

Five credentials sit at the company level, each independently verifiable: ISO 17100:2015 (international standard for translation services — anchors the bilingual EN/TH workflow with TEP discipline); ATA Affiliated (American Translators Association corporate member — US-market recognition); ATC Accredited (Association of Translation Companies accredited member — UK/EU-market recognition); GDPR Compliant (EU data protection — important for European institutional clients and cross-border data handling); PDPA Compliant (Thailand Personal Data Protection Act — required for SET-listed and Thai SOE engagements).

The five company-level credentials operate alongside the ESG Advisory methodology credentials: IFRS Foundation S1 & S2 (2025), ISO 14064 Lead Auditor CQI/IRCA (June 2024), AA1000AS ACSAP (June 2024), GRI 2021 Certified Trainer (June 2023), TGO CFO + CFP Auditor (2020), and the FTSE Russell ESG 4.0/5.0 cross-anchor verifiable proof (2025). The two layers cover different aspects: company credentials cover trust and data handling at firm level; bench credentials cover substantive technical methodology for specific advisory engagements.

Four verification vectors. (1) FTSE Russell ESG 4.0/5.0 secured for a SET-listed healthcare operator in 2025 — independently verifiable through FTSE Russell published score data. The score is public; the issuer is identifiable from FTSE Russell’s score disclosure. This is the strongest single piece of verifiable proof in the ESG advisory portfolio. (2) ISO 17100:2015 certification — verifiable through the certifying body. (3) ATA + ATC accreditation — verifiable through each association’s published member list.

(4) Named bench credentials at engagement scoping — each ESG Advisory engagement names the specific specialist(s) on the engagement letter; their individual credentials (IFRS Foundation, CQI/IRCA, AccountAbility, FTPI, TGO, Verra) are independently verifiable through the issuing bodies. Specific Othello-supported engagements beyond the public FTSE proof are available as references under mutual NDA at procurement stage — confidentiality is the commercial standard, but references are available to procurement teams running formal RFP processes.

Big 4 and Othello operate on different commercial models. Big 4 ESG teams in Thailand are anchored to global frameworks, run premium-priced engagements (typical minimum engagement THB 3–5 million for ESG advisory), and bring deep audit-and-assurance methodology — particularly strong for SET100 large-cap and multinational subsidiary work. Their structural strengths are scale, global brand recognition, and bundled audit + ESG offerings.

Othello is built for the next tier down: SET-listed mid-cap and smaller corporates, Thai SOE issuers, financial institutions, and Big Law clients who need substantive methodology without Big 4 fee structures. Structural strengths: (1) bilingual EN/TH lockstep is native rather than retrofitted (Big 4 ESG teams often write in English and translate; Othello drafts in parallel from day one); (2) in-house specialist bench with named individual credentials rather than outsourced or junior-staffed; (3) FTSE Russell 4.0/5.0 verifiable proof at a SET-listed healthcare operator; (4) same firm handles translation + advisory — single procurement, single NDA, single bench, no handoff loss between English drafting and Thai disclosure.

Many SET-listed corporates engage both: Big 4 for assurance and statutory audit, Othello for translation + ESG advisory + bilingual sustainability reporting. The two are complementary, not directly competitive on the same engagement.

Three structural commitments. (1) Before any source material crosses from client to Othello — including during scoping conversations, at RFP stage, and during sample engagements — a mutual NDA is signed. The default Othello NDA template is available on request; client templates are reviewed and signed within one business day if standard terms apply. (2) The NDA covers the entire engagement lifecycle: scoping, source review, deliverable drafting, post-delivery, and reference disclosure. Specific Othello-supported engagements are not disclosed publicly without explicit client written authorisation; references are available under mutual NDA at procurement stage.

(3) The bench is 100% in-house — no source material is shared with external freelancers, no outsourcing to overseas vendors, no LLM-based processing that retains source data. Translation Memory and termbase assets are stored on Othello-controlled infrastructure with GDPR + PDPA compliant data handling. The NDA standard is what makes Big Law and US government engagements operationally viable; it remains the default for SET-listed and ESG advisory work.

Both, scaling to client needs. One-off projects are common for translation work (single annual report, single sustainability report, single regulatory filing) and for time-bound ESG advisory engagements (FTSE Russell readiness for a specific assessment cycle, IFRS S2 first-year disclosure, single SLB framework drafting). Pricing is fixed-fee with scope locked at engagement.

Programmatic retainers are common for multi-year client relationships: annual sustainability report programmes running 3–5 years (compounding TM savings); ESG advisory retainers covering ongoing FTSE Russell engagement, annual SLB observation-date verification, Thailand Taxonomy annual review, IFRS S2 ongoing climate disclosure; combined multi-instrument programmes for issuers running green bond + SLB + green loan suites where the same bench coordinates strategy upstream, framework drafting, SPO coordination, and post-issuance reporting. Retainers deliver materially better economics in Year 2+ — typically 40–60% reduction on Year 2+ work compared to standalone equivalent.

The right answer depends on engagement substance and client procurement constraints. Quote on either model within one business hour of scope brief + NDA.

The core practice is English ↔ Thai at ISO 17100 lockstep — this is where the in-house bench is deepest and where the methodology is built. Beyond the core, Othello covers ASEAN regional languages through the in-house bench plus vetted regional partners under Othello’s NDA discipline: Lao, Burmese, Khmer, Vietnamese, Bahasa Indonesia, Bahasa Malaysia, Tagalog. These are typically commissioned for cross-border legal work, ASEAN-regional ESG disclosure, regional banking documentation, and government RFPs requiring CLMV (Cambodia, Laos, Myanmar, Vietnam) coverage.

European and East Asian languages — French, German, Spanish, Italian, Japanese, Korean, Mandarin Chinese — are commissioned through Othello-managed external linguist relationships under Othello’s NDA standard and ISO 17100 workflow discipline. Othello handles the project management, terminology consistency, and quality assurance; the linguistic work is done by accredited specialists in each language. For ESG advisory work, the practice is English + Thai only — the methodology depth and bench credentials are anchored to those two languages.

Four steps, typically 3–10 business days from first contact to work beginning depending on scope complexity. (1) First contact via email, phone, or contact form — sets up a 30-minute scoping call to understand the engagement substance, timeline, and confidentiality requirements. (2) Mutual NDA signed — Othello template available on request; client templates reviewed and signed within one business day if standard terms apply. (3) Scope brief + source material exchange under NDA — Othello reviews source material, identifies methodology approach, named bench specialists, and engagement structure. (4) Quote delivered within one business hour of receipt of source material and signed NDA — fixed-fee structure, scope locked, timeline committed.

For formal RFP processes, standard response is 3–5 business days covering methodology approach, named bench credentials, capacity allocation, pricing structure, related-methodology track record, and integration with adjacent practice areas where relevant. RFP response is delivered under mutual NDA. Contact us to start a conversation, or call +66 02-859-2145 directly.
