Mark McCall

Managing Director

2024 - Current

Founded in 2017, Argonautic Ventures is a top-tier investment fund focused on venture capital and growth equity. Argonautic’s core focus revolves around machine learning (ML) and deep learning as this technology will redefine how the world will digitize and interact with technology. Our ML / deep learning thesis is two-pronged. The first is partnering with businesses that build the infrastructure that enables ML / deep learning tools to be built upon. We invest across the entire ML lifecycle, which further strengthens our investments in the space because of the lifecycle’s cyclical nature. The second is industry-specific ML & deep learning applications with domain-specific data sets that can be used to build and train models for the problems in that industry. The industries where ML and deep learning can generate the greatest value (and therefore returns) are Construction Technology, Fintech and Computational Biotech. The Fund also has significant investments in Food/Agtech.
