Our Team

Our team brings a distinctive blend of expertise to the investment landscape. Although our background is rooted in real estate development rather than traditional finance, our experience ranging from managing a successful real estate software platform to serving funds and asset owners has sharpened our ability to identify lucrative opportunities and navigate industry complexities.

From this perspective, we recognised the potential to optimise investments through a more efficient vehicle. Theta Capital was established as a result, embodying our commitment to forward-thinking strategies and offering a fresh approach to achieving consistent returns.
