When approaching Castles:
Her award-winning work continues to shape Australia’s approach to ethical tech development, making her an essential contact for startups aiming to align profit with purpose.
Angela Castles has carved a unique path in journalism, blending her legal acumen with a passion for technology and innovation. Beginning her career with a Bachelor of Laws/Journalism from the University of Queensland, she initially explored legal journalism, dissecting regulatory challenges for startups at Women’s Agenda and StartupSmart. This foundation equipped her to analyze complex tech policies with precision, a skill that became her trademark.
Her transition to Startup Daily marked a shift toward deep-tech reporting, where she now chronicles Australia’s burgeoning startup ecosystem. Over the past five years, Castles has become a leading voice on sustainable technology and AI ethics, often highlighting underrepresented founders in her pieces.
This 2024 analysis piece mapped how quantum computing and AI-driven climate models are attracting venture capital to Australian deep-tech ventures. Castles interviewed 15 founders and investors, revealing a 300% funding increase in climate tech startups since 2022. Her methodology combined data visualization with founder narratives, making complex technologies accessible to mainstream audiences.
"Australia’s tech landscape isn’t just catching up with Silicon Valley—it’s creating its own playbook for ethical AI development."
Published during her tenure at Women’s Agenda, this investigative piece exposed regulatory gaps in Australia’s startup visa program. Through FOIA requests and interviews with 40 immigrant founders, Castles revealed how 62% of tech startups faced unnecessary bureaucratic delays. The article prompted parliamentary discussions about streamlining innovation visas.
Her 2023 feature at SmartCompany profiled three Australian startups revolutionizing battery storage using recycled materials. Castles embedded with engineering teams for two weeks, documenting their R&D processes through video interviews and interactive infographics. The piece drove a 40% increase in investor inquiries for profiled companies.
Castles prioritizes stories exploring how technologies address social inequities. A successful pitch might highlight a startup using blockchain to verify fair-trade supply chains or AI models that reduce healthcare disparities. For example, her 2024 piece on an Indigenous-owned AI firm demonstrated her interest in culturally responsive innovation.
When pitching renewable energy startups, include verifiable data on carbon reduction or resource efficiency. Castles’ coverage of a solar panel recycling venture specifically highlighted their metric of “1 ton of landfill waste diverted per $10,000 invested.”
She frequently covers partnerships between tech startups and traditional industries. A recent article on AI-driven mineral exploration showcased how a machine learning firm collaborated with mining companies to reduce exploratory drilling by 70%.
Castles amplifies startups led by women, LGBTQ+ individuals, and multicultural teams. Pitches should explicitly note leadership demographics and any unique cultural perspectives informing product development.
Her work centers on B2B and infrastructure technologies rather than consumer electronics. A pitch for a new smartwatch or gaming hardware would likely fall outside her scope.
2023 Australian Tech Media Award - Won for her investigative series on AI bias in hiring algorithms, which prompted three ASX-listed companies to audit their HR tech stacks. The judging panel noted her “rare ability to translate technical research into public accountability journalism.”
