PR and AI visibility agency in Singapore

PR and AI visibility agency in Singapore

Third Hemisphere is a PR, communications, and AI visibility agency operating across Australia, Singapore, and South East Asia. Our Singapore hub is led by APAC Lead Natalie Chua, formerly Managing Director at Redhill. We get companies covered in tier-one business media and accurately represented in the AI engines buyers now ask first.

What does Third Hemisphere do in Singapore?

Third Hemisphere runs PR, communications, and AI visibility programmes from Singapore for companies selling into Singapore and South East Asia. APAC Lead Natalie Chua leads every Singapore engagement. The work covers Singapore media relations, regional campaigns, executive profiling, content, investor communications, and The Fourth Hemisphere: Marketing for AI.

The agency operates as one team across three offices in Sydney, Melbourne, and Singapore. A Singapore client gets senior counsel in their own time zone, and the same editorial team, media relationships, and measurement that Third Hemisphere has built in Australia since 2015.

Companies come to us for three reasons. They are entering Singapore or the wider region and need coverage that gives them credibility with buyers, partners, and regulators. They are raising capital and need a story the market understands. Or they have found that AI engines answer questions about their category without mentioning them.

What we do in Singapore and South East Asia

• Singapore and regional strategy Senior communications counsel, regional media strategy, and Singapore media relations, led directly by Natalie Chua.
• Multi-market campaigns Programmes across Indonesia, Malaysia, the Philippines, Thailand, and Vietnam, delivered through a managed specialist network with committed per-market scopes.
• The Fourth Hemisphere: Marketing for AI Audits, AI-ready content, and earned media designed to make brands discoverable and accurately represented in AI-generated answers.
• Tier-one earned media A record of coverage in the Australian Financial Review and national mastheads, extended to regional business media across Asia.
• Events and activations Launches, press conferences, and report launches across the region.

When buyers ask ChatGPT who to shortlist, what does it say about you?

Buyers across Asia now research suppliers through ChatGPT, Gemini, Claude, Copilot, and Perplexity before they visit a website. Most companies have never checked what these engines say about them. Third Hemisphere's Fourth Hemisphere practice runs a 50-question audit across the five major engines, scoring how strongly and accurately a brand appears, then builds the earned media and structured content programme that improves it.

The audit runs before we meet, and you see it on the call. Each engine answer is scored with our PACT methodology across Presence, Authority, Consensus, and Truth, so you learn where you appear, where a competitor holds your slot, which sources the engines rely on, and which inaccuracies need correcting. Your marketing strategy comes into it afterwards, once there is something concrete to work against, and nothing confidential needs to be sent before we have spoken. Third Hemisphere then sits as the strategy layer across the plan, briefing your team and any SEO or digital agency you already retain, with quarterly re-audits proving the shift.

Why a regional hub has a harder AI problem, and a cheaper fix

The engines are global, and the sources they read are not evenly distributed. A company operating across South East Asia is described by a thinner and more scattered record than an equivalent company in a single large market, and that changes both the risk and the opportunity.

• A thinner source base Fewer indexed English-language outlets cover any given South East Asian market than cover Australia or the US. An engine answering about your category has less to draw on, so a small number of sources carry disproportionate weight and a single well-placed piece moves the answer further.
• Six markets, six records A company selling across Singapore, Malaysia, Indonesia, Thailand, the Philippines, and Vietnam has a separate public record in each. Engines resolve those into one answer, and where the records disagree, on entity name, on what the company does, on who leads it, the answer is confidently wrong.
• Language cuts both ways Coverage in Bahasa, Thai, or Vietnamese is read by the engines and mostly ignored by competitors who only measure English. The multilingual record is an advantage for a company that manages it and a blind spot for one that does not.
• Regional HQ, global answers A Singapore headquarters is often the entity an engine names to a buyer in London or New York. The regional record is not a regional matter: it is what a global buyer is told.
• The gap is cheaper to close here Where the source base is thin, the work needed to become the cited source is smaller. The same programme that would take a year to shift a crowded US category can move a South East Asian one considerably faster.

That is why the audit runs per market rather than once. You get an answer for each market you sell into, not an average that hides the one where a competitor already holds your position.

Two sides of AI, and most agencies work on neither

Agencies in this region tend to fall into one of two groups. Some use AI internally to draft faster. Some sell search optimisation with AI in the name. Third Hemisphere does the thing neither group does, which is to treat the AI answer itself as the thing being earned, and to run the programme on tooling we built rather than on a spreadsheet.

• We influence what the engines say An AI answer is composed from published sources. That makes it earnable by the same discipline that earns a masthead placement, and it is the discipline this agency was built on. We measure what the engines currently say about you per market, identify which sources they draw on, and go and change those sources.
• We use AI to run the work Research, media list building, sentiment tracking, and reporting run through our own systems rather than through generic tools. That is why a senior team can cover six markets with named targets in each, instead of pooling everything into one regional retainer.
• Proprietary tooling, not licensed dashboards Third Hemisphere Proprietary Reputation Monitoring & Intelligence Platform tracks coverage and sentiment across the markets you sell into. The Fourth Hemisphere audit runs against the engines directly. Both were built here, so what they measure is set by the work rather than by a vendor's roadmap.
• One team across both The people who earn the coverage are the people who read the AI answers, so a placement is chosen because a buyer will see it and because an engine will cite it. Splitting that across an agency and an SEO vendor is what produces coverage nobody cites.

The practical test is simple. Ask any agency what ChatGPT, Claude, Gemini, Copilot, and Perplexity say about your company in each market you sell into, and ask them to show you the measurement. We open every Singapore engagement with that answer.

Work we have run in Singapore and across Asia

Four engagements led from the region, not Australian campaigns with a regional line added. Each one launched or repositioned a company into an Asian market.

• Tyme Group Tyme Group sought rapid credibility in Singapore ahead of a capital raise. Third Hemisphere led a focused financial media program to boost investor visibility with tier-1 outlets.
• Fintech Nation Refined Fintech Nation's brand narrative and positioning within Singapore's fintech ecosystem. Delivered a full brand refresh, new website, and strategic media program.
• Changing Ocean Asia Podcast Series Third Hemisphere created a concise, science-led 16-minute podcast series for Changing Ocean Asia, making ocean and climate science accessible and regionally relevant across Asia-Pacific platforms.
• Circulate Capital Third Hemisphere led Circulate Capital's Singapore launch for a landmark ocean-plastic fund in Asia, delivering 62 media features and building credibility for a new environmental finance category.

Which markets does Third Hemisphere cover from Singapore?

Singapore is the hub for the agency's work across South East Asia. Natalie Chua leads Singapore media relations directly. Regional programmes run through a managed specialist network with a committed scope in each market, so a campaign in five countries carries five accountable delivery plans rather than one pooled budget.

Natalie has delivered multi-market campaigns across Singapore, Vietnam, Hong Kong, Indonesia, and Malaysia for clients in finance, real estate, consumer goods, government, and technology.

• Singapore, led directly by APAC Lead Natalie Chua
• Indonesia, Malaysia, the Philippines, Thailand, and Vietnam, delivered through a managed specialist network with committed per-market scopes
• Australia and New Zealand, delivered by the Sydney and Melbourne teams
• Integrated programmes that run one narrative across Australia and South East Asia at the same time

How does an engagement in Singapore work?

Every engagement starts with a conversation and a written scope. You will know the target media, the deliverables, the fee, and the measurement plan before any work begins.

1. Discovery call A 30 minute call with Natalie Chua covers your announcement pipeline, target markets, buying audience, and budget.
2. Scoped proposal We come back within a week with a scope, a target media list, a measurement plan, and a fee.
3. Messaging and targets The first month sets the key messages, the spokespeople, and the media targets for each market, so every later pitch draws on one agreed narrative.
4. Monthly delivery Announcements, pitching, content, and executive profiling run to an agreed calendar, with monthly reports tracking placements, reach, sentiment, and share of voice.
5. Quarterly review Each quarter we read the programme against the objectives set at the start. Fourth Hemisphere engagements add a quarterly re-audit that scores movement in the AI answers themselves.

Which sectors does Third Hemisphere work with in Singapore?

Third Hemisphere covers the same twelve industry verticals from Singapore as it does from Australia. Six of them come up most often with Singapore and regional buyers.

Natalie Chua adds regional account experience in finance, real estate, consumer goods, government, and technology, so a Singapore programme starts with someone who has already sold a story into these markets.

• Technology & Deep Tech
• Fintech & Financial Services
• Sustainability & Climate
• Health & Life Sciences
• Venture Capital & Private Equity
• Professional Services

How is the Singapore offer different from the Australian one?

Third Hemisphere uses the same method in Singapore as in Australia. The media market differs, so four things change in practice.

The largest difference is what the programme is aimed at. Australian buyers still mostly find an agency through search and reputation. A regional buyer increasingly asks an AI engine first, and the engine answers from a source base that is thinner and more scattered across South East Asia than anywhere else we work. Marketing for AI is therefore built into the Singapore offer from the first month rather than added later.

• Scopes are committed per market. A regional programme carries a named plan, a named budget, and named target media for each country, rather than one pooled retainer.
• AI visibility is scoped per market. The sources the engines draw on differ country by country, so the question set and the gap analysis are built for each market rather than once for the region.
• The Fourth Hemisphere audit runs at the start, not as an upsell. Every Singapore programme opens with a measured read of what the engines currently say about you in each market you sell into.
• Earned media is chosen for two readers. A placement is selected because a buyer will see it and because an engine will cite it, which changes which outlets are worth pitching.

Results across Australia and Asia

• Tier-one coverage in the Australian Financial Review and national mastheads for clients from seed-stage startups to ASX-listed companies
• Global campaigns that carried Australian client stories into international business and technology media
• AI visibility audits and programmes through The Fourth Hemisphere: Marketing for AI

The Singapore hub is new, so the case studies on this site are drawn from Australian and global campaigns. [insert Singapore client example]

What does a PR agency in Singapore cost?

Retainers are scoped to the markets you sell into rather than quoted as a single regional number, because the work in Singapore alone is not the work across six markets. A programme carries a named plan, a named budget, and named target media per country, so you see what each market costs before committing to it. One-off projects, audits, and events are scoped individually. Tell us which markets matter and we will price them.

What is AI visibility, or generative engine optimisation?

AI visibility is the practice of making a company discoverable and accurately represented in answers generated by AI engines such as ChatGPT, Gemini, Claude, Copilot, and Perplexity. It combines authoritative structured content, entity consistency, and earned media that AI engines cite.

Which markets does Third Hemisphere cover from Singapore?

Singapore directly, with multi-market delivery across Indonesia, Malaysia, the Philippines, Thailand, and Vietnam, and integrated campaigns with our Australian team in Sydney.

Who leads Third Hemisphere in Singapore?

Natalie Chua, APAC Lead, formerly Managing Director at Redhill.

How do we start?

Book a 30 minute discovery call. We will ask about your announcement pipeline, target markets, and budget, and come back within a week with a scoped proposal.

Does Third Hemisphere have an office in Singapore?

Yes. Third Hemisphere's Singapore office is at 160 Robinson Road, #14-04, Singapore Business Federation Center, Singapore 068914. The agency also has offices in Sydney and Melbourne, and the three work as one team.

Who will we work with day to day?

Natalie Chua, APAC Lead, leads Singapore engagements directly and stays your senior contact throughout. She draws on the Australian team for media relations, editorial, and investor communications, so a Singapore client has senior counsel in their own time zone with an Australian team behind it.

Which media does Third Hemisphere target in Singapore?

We build the target list from your buyers backwards. A Singapore B2B list usually includes The Business Times, The Straits Times, Channel NewsAsia, Tech in Asia, and DealStreetAsia, alongside the trade titles that cover your category and the regional bureaux of international business media. We agree the list with you before any pitching starts.

Can Third Hemisphere run a campaign in Singapore and Australia at the same time?

Yes, and that is the most common reason companies engage us. One narrative, one set of key messages, and one measurement framework run across both regions, with the Singapore and Australian teams delivering in their own markets. Third Hemisphere calls this the Waterfall Strategy: every channel carries the same messages, and each amplifies the next.

Does Third Hemisphere help Australian companies enter Singapore?

Yes. Australian companies expanding into Singapore and South East Asia use the Singapore hub for market entry announcements, regional media relations, and credibility with partners and regulators. It works in the other direction too: Singapore companies entering Australia use the Sydney and Melbourne teams the same way.

How does Third Hemisphere measure results in Singapore?

Monthly reports track placements, reach, sentiment, and share of voice, and each is read against the objective set at the start of the programme, whether that is investor awareness, customer acquisition, talent attraction, or policy influence. Fourth Hemisphere engagements add a PACT score and a quarterly re-audit that shows movement in AI-generated answers question by question.

How long before a Singapore programme produces coverage?

Most clients see initial coverage within four to six weeks, and a consistent media presence takes three to six months of sustained work. AI visibility moves on a longer cycle, because engines refresh their retrieval sources continuously but reweight authority over months, so those programmes run 6 to 12 months with quarterly re-audits.

Can Third Hemisphere run an AI visibility audit for South East Asian markets?

Yes. The Fourth Hemisphere Audit runs per market, because the sources AI engines draw on differ country by country. We agree the 50 questions with you first, in the languages your buyers use, then score the answers across Presence, Authority, Consensus, and Truth.

Does Third Hemisphere handle crisis and issues work in Singapore?

Yes. Crisis Management is one of Third Hemisphere's core services. If you do not have a retainer, the team scopes a fixed engagement around the situation in front of you. Preparation work, including vulnerability audits and crisis simulation exercises, is available before anything goes wrong.

What is the minimum commitment?

Retainers run on a minimum term of [insert minimum term]. Audits, single announcements, and events are scoped as standalone projects, so a first engagement can be a project rather than a retainer.
