Third Hemisphere’s decade-long evolution from fintech specialist to multi-sector communications powerhouse
When Third Hemisphere launched its communications practice focused on Australian fintech startups, the agency’s founders made a strategic bet: deep sectoral expertise would prove more valuable than generalist capabilities. A decade later, that thesis is validated through the agency’s expansion across investment management, fusion energy, healthcare AI, and social enterprise – sectors that share complex regulatory environments and sophisticated stakeholder dynamics but serve vastly different markets.
The agency’s portfolio evolution demonstrates how specialized expertise in one sector can unlock opportunities across adjacent domains, creating a diversified client base while maintaining the deep knowledge that differentiates boutique agencies from generalist competitors.
Financial services foundation: From neobanks to private credit
Third Hemisphere built its reputation supporting Australian fintech pioneers through market entry, regulatory approval, and growth phases. Campaigns for digital lender MONEYME positioned the company as a market leader, supporting approximately $700 million in asset-backed securities transactions. The agency also worked with Volt, Australia’s first neobank, and OKX Australia, navigating the cryptocurrency platform through complex regulatory positioning.
This fintech foundation now extends into investment communications with recent wins spanning multiple strategies. GPS Investment Fund Limited represents the private credit sector, operating as a first mortgage lender where management invests alongside clients. Axletree brings sustainable technology growth equity, providing patient capital to companies across agriculture, transport, and advanced manufacturing. Scalare Partners adds venture capital expertise to the portfolio mix.
The common thread across these diverse investment strategies is the need for complex regulatory frameworks, sophisticated investor audiences, and communications partners who understand both financial mechanics and market positioning. Third Hemisphere’s decade navigating ASIC regulations and Australian institutional investors provides natural transferability to other investment sectors requiring similar stakeholder management.
Hannah Moreno, founder and CEO of Third Hemisphere, said: “These wins represent our natural evolution across sectors. We’ve spent a decade helping Australian pioneers establish credibility and drive growth, from fintech and investment to climate technology and social impact. Now we’re applying that expertise across Singapore’s sophisticated ecosystem. Each client requires communications partners who understand not just the technology or investment strategy, but the regulatory frameworks and stakeholder dynamics that determine success in these markets.”
Climate technology: Translating deep science for commercial audiences
Third Hemisphere’s expansion into climate technology reveals another dimension of the agency’s sectoral evolution. Supporting fusion energy companies HB11 Energy and Type One Energy requires translating complex physics into accessible narratives for investors, policymakers, and media audiences – skills that parallel the agency’s fintech work explaining blockchain, tokenization, and decentralized finance to mainstream audiences.
HB11 Energy is creating electricity through small nuclear fusion reactors using hydrogen and boron-11, producing energy without steam turbines by directly converting charged particles. Type One Energy develops stellarator fusion systems using advanced manufacturing and high-field superconducting magnets. Both companies require communications support that can bridge technical innovation with commercial opportunity while navigating policy frameworks and public perception challenges around nuclear technology.
The fusion energy work complements Third Hemisphere’s support for Australian Parents for Climate, the country’s leading climate advocacy organisation for families. The combination of deep technology innovation and grassroots advocacy demonstrates the agency’s range across the climate sector.
Healthcare AI and sports technology: New frontiers
Third Hemisphere’s most recent sector expansion includes healthcare AI through Care GP, Australia’s first agentic AI suite for GP clinics. The platform automates medical documents, billing, and patient communications, saving clinics an average of 4.3 hours daily while integrating with existing practice systems through privacy-by-design architecture.
Healthcare technology communications requires managing multiple stakeholder audiences—medical professionals, clinic administrators, patients, regulators, and privacy advocates—each with distinct concerns and information needs. The sector combines regulatory complexity familiar from fintech work with the sensitivity and trust requirements of health data, creating a communications challenge that rewards specialized expertise.
Golf.ai adds sports technology to Third Hemisphere’s portfolio, pioneering AI-powered golf solutions that make the game more accessible through advanced data analytics and real-time insights. The platform demonstrates the agency’s capability supporting consumer-facing AI applications alongside enterprise and B2B technology clients.
Social enterprise: Mission and commercial outcomes
Third Hemisphere’s social enterprise portfolio reflects the agency’s values-driven approach while demonstrating commercial sophistication. Oho, Australia’s only dedicated credential verification platform, has detected over 500 critical safeguarding risks across 135 organisations while saving over 110,000 hours in compliance administration. The platform combines social mission—protecting children and vulnerable people—with clear commercial value proposition and regulatory compliance requirements.
The Orbispace Initiative delivers STEAM education programmes for young women, with students 50% more likely to pursue STEM subjects than peers. Women & Children First provides emergency accommodation and support for women and children experiencing homelessness or domestic violence. Both organizations require communications approaches that prioritize impact storytelling while building credibility with funders, partners, and policy makers.
Jeremy Liddle, Managing Director, said: “The geographic and sector expansion was carefully timed. We built deep expertise across multiple domains in Australian markets first, which created the foundation for regional growth. Singapore represents a natural next step given the sophistication of its financial, technology, and impact investing sectors.”
Cross-sector patterns: What unifies diverse portfolio
Despite spanning fintech, investment, fusion energy, healthcare AI, sports technology, and social enterprise, Third Hemisphere’s portfolio reveals consistent patterns. Most clients operate in regulated or policy-sensitive environments. All require sophisticated stakeholder management across investors, customers, partners, regulators, and media. Many combine technical innovation with commercial execution, requiring communications support that can translate complexity into accessible narratives.
The agency’s awards validate this cross-sector approach: Mumbrella Boutique Agency of the Year and SABRE Best Financial Services Campaign, with Moreno earning B&T’s Technology Woman of the Year and Mumbrella’s PR Professional of the Year.
Third Hemisphere’s team composition supports the multi-sector strategy, with experts from media, politics, and venture capital bringing complementary perspectives across technology, capital markets, sustainability, and policy domains.
As sectoral boundaries blur and innovative companies increasingly operate across multiple domains—fintech platforms adding healthcare services, climate companies requiring sophisticated investment strategies, technology companies addressing social challenges—demand for communications agencies with genuine cross-sector expertise will intensify. Third Hemisphere’s decade building that capability positions the agency to capture opportunities in an increasingly complex and interconnected business landscape.
