Who we are and
how we work
Ayutthaya Partners is a small sustainability consultancy based in Bangkok. We work with Thai companies navigating environmental, social, and governance questions that are becoming increasingly relevant to their stakeholders.
← Back to Home⟁ our story
Rooted in a specific place and moment
Ayutthaya Partners was founded by practitioners who had spent years working within Thai corporate environments — in finance, in operations, in regulatory engagement — and who noticed a particular gap: businesses genuinely interested in sustainability questions, but uncertain where to begin and wary of engagements that produced elaborate documents without improving internal understanding.
The name draws from the historical city of Ayutthaya — a trading centre whose durability came not from single-minded expansion but from careful, adaptive relationships with its neighbours and environment. That is, loosely, the disposition we bring to this work.
We are a small practice by design. Each engagement is led by a senior practitioner with direct experience of how Thai businesses operate, what their stakeholders currently expect, and how regional frameworks are likely to develop. We do not have a large delivery team; we have a small, careful one.
Our focus is Thailand and the broader Southeast Asian region. We are familiar with the SEC Thailand disclosure landscape, the expectations of regional institutional investors, and the sustainability questions that Thai supply chains are increasingly fielding from international customers.
MISSION
"To support Thai businesses in building sustainability practice that is genuinely their own — capable of continuing and evolving without us."

⟁ team
The people involved
We keep the team small so that the people clients meet at the start of an engagement are the ones doing the work throughout.
Pichaya Nanthakorn
FOUNDING PARTNER
Fifteen years in corporate finance and investor relations, including senior roles at two SET-listed companies. Pichaya leads baseline reviews and framework engagements, with particular experience in the materials and manufacturing sectors.
Sarun Wattanaporn
PARTNER, ADVISORY
A background in operations and supply chain management, latterly focused on environmental data systems and scope 3 measurement. Sarun works primarily with retainer clients and leads on indicator mapping within framework engagements.
Kannika Limsiri
ASSOCIATE, RESEARCH
Kannika supports research, data analysis, and written drafting across all three service lines. She holds a graduate qualification in environmental management and brings particular knowledge of disclosure practices in the food and agriculture sectors.

How we approach quality
These are not certifications so much as descriptions of how each engagement is structured and checked.
Written scoping before work begins
Each engagement begins with a written scope note that the client reviews and agrees to before work proceeds. This document sets out what will and will not be covered, and it is available for reference throughout.
Peer review of written deliverables
All written outputs — memoranda, implementation plans, session notes — are reviewed by a second practitioner before being sent to the client. Factual claims about frameworks or regulations are sourced and noted.
Confidentiality by default
Client information — financial data, operational details, governance arrangements — is held in confidence. We do not reference clients in marketing materials without explicit permission. A short confidentiality letter accompanies every engagement.
Framework currency
We monitor developments in GRI, ISSB, TCFD, SASB, and SEC Thailand disclosure requirements on an ongoing basis. When guidance changes in ways relevant to a client engagement, we note this and update our approach accordingly.
Clear conflict of interest policy
We do not accept referral fees from data providers, software vendors, or certifying bodies. Our framework recommendations are not influenced by commercial relationships. This is disclosed to clients at the start of each engagement.
Feedback at close
At the conclusion of each engagement, we invite a short written reflection from the client team — what was useful, what could have been clearer, what they would change. These responses inform how we structure subsequent engagements.
⟁ context
The sustainability landscape in Thailand
Thai businesses are facing an expanding set of sustainability disclosure expectations — from the Securities and Exchange Commission Thailand's climate-related disclosure guidance for listed companies, to the sustainability questionnaires that international customers and supply chain partners are increasingly sending to their Thai suppliers.
The context here differs from that in Europe or North America in important ways. Mandatory disclosure frameworks are still developing. Industry norms around what constitutes a credible first report are not yet settled. And the practical capacity of finance and operations teams to gather environmental and social data is highly variable.
Ayutthaya Partners works within this context rather than against it. Our engagements are designed for where Thai businesses actually are — not where a global framework assumes they should be. A company producing its first sustainability baseline review is not behind; it is at a particular stage, and the work we do with it is calibrated to that stage.
We pay attention to how peer companies in Thailand and the region are approaching these questions, and we bring that awareness into our advisory sessions. Clients find it useful to understand not just what a given framework requires, but how other businesses of comparable size and sector are interpreting those requirements in practice.
