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 Managing Director 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. Managing Director 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.

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 Fourth Hemisphere Audit scores each answer with our PACT methodology across Presence, Authority, Consensus, and Truth. You see where you appear, where a competitor holds your slot, which sources the engines rely on, and which inaccuracies need correcting. From there, a 6 to 12 month programme of earned media, AI-ready content, and entity work moves the score, with quarterly re-audits proving the shift.
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.

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.
- Discovery call A 30 minute call with Natalie Chua covers your announcement pipeline, target markets, buying audience, and budget.
- Scoped proposal We come back within a week with a scope, a target media list, a measurement plan, and a fee.
- 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.
- Monthly delivery Announcements, pitching, content, and executive profiling run to an agreed calendar, with monthly reports tracking placements, reach, sentiment, and share of voice.
- 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 three things change in practice.
- 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.
- Pricing anchors differ. A Singapore programme led by a senior team typically starts at SGD 10,000 per month, and a regional South East Asia programme covering several markets is typically about USD 15,000 per month depending on scope.
- 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.
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 for a Singapore programme led by a senior team typically start at SGD 10,000 per month. Regional South East Asia programmes covering several markets are typically about USD 15,000 per month depending on scope. One-off projects, audits, and events are scoped individually.
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, Managing Director, 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, Managing Director, 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.
