Daniel Petre is one of the few Australian VCs who ran a major Microsoft product group and reported directly to Bill Gates, later founding three significant investment firms including co-founding AirTree Ventures. After stepping back from day-to-day VC work, he created StartGiving to help tech founders establish their own foundations and has personally donated over A$25 million through the Petre Foundation while fully funding the philanthropic infrastructure he built.
What they've been talking about across their social media accounts

- Deep commitment to philanthropy and social responsibility within the startup ecosystem. He actively encourages founders and wealthy individuals to engage in giving back, highlighted by his launch of StartUpGiving and his consistent sharing of articles questioning why the wealthy avoid philanthropy.
- Advocacy for supportive government policy regarding innovation and R&D. He frequently critiques legislative decisions that hinder the tech sector, such as the exclusion of software development from research and development tax incentives or poor planning around industry growth.
- Strong focus on climate action and frustration with performative environmental policies. He often challenges government plans that lack specific emission goals or rely on discredited technologies, emphasizing the need for genuine sustainability efforts over political posturing.
- Appreciation for deep science and significant academic research. He celebrates fundamental discoveries, such as the Garvan Institute identifying the origins of early humans, and values substantial scientific breakthroughs over corporate buzzwords.
- Personal connection to loss and compassion. He shares reflective content about the human experience, including annual messages honoring his late sister and quotes about how suffering and struggle can lead to greater empathy and depth of character.
- Skepticism toward traditional corporate leadership claiming to be disruptive. He differentiates between true tech visionaries and standard corporate executives, notably rejecting comparisons between telecommunications CEOs and actual industry pioneers like Elon Musk.

Notable Investments
AirTree Ventures operates as one of the few VC firms globally to build a large "Open Source VC" library with hundreds of detailed playbooks, templates, and legal documents made freely available to all founders—not just portfolio companies—effectively turning the fund into an education and infrastructure layer for the ANZ startup ecosystem. The firm pioneered a public Diversity Pledge tied to every lead investment, committing to bring at least one investor from an underrepresented group onto the cap table for every deal it leads, and runs "Explorer," a free angel-investor training program with deliberate focus on women and non-traditional investors that combines education, deal access, and co-investment opportunities.
