I’m Airtree’s Investor Relations Manager. I build and run the engine behind investor relations: how we engage our LPs and the day-to-day operations of running a fundraise.

Most of my career has been in IR for climate and nature, raising capital at C40 Cities in London, then running client operations across ANZ natural-capital funds at New Forests in Sydney. I first connected with Airtree in a very Airtree way: by building something. I created a demo showing how I’d automate part of the fundraising CRM, then used that same system to start a conversation with the team.

A common thread throughout my career

Systems thinking. Whether I’ve been working in climate philanthropy, natural-capital investment or now venture, the underlying work has always been similar: taking fragmented processes, relationships and information, then turning them into infrastructure that runs.

What I nerd out over

Climate, and specifically climate capital allocation. Most of my career has been in this space, and the question I keep coming back to is how we close the gap between good climate projects and deployable capital at scale across infrastructure, technology and nature-based solutions. I’ll happily talk through where capital is flowing, where it isn’t, and where it probably should be. Outside of that, music and books. My favourites are Death Cab for Cutie and Taylor Swift, which sounds like an odd pairing, but both are masters of telling a complete story inside a song. On the books side, mostly fiction, plus anything I can find on yoga.

Here’s where you’ll find me on the weekend

At a sunrise yoga class at my local studio in Maroubra, in the ocean, wandering through a gallery or museum somewhere in the city with my partner, or on my bike heading somewhere I haven’t been before.
