Charles Srisuwananukorn stands out for hands-on infrastructure work most investors never touch, like diagnosing overheating transceivers with an infrared camera and keeping optical fiber clean to keep InfiniBand networks stable, and for pointing out specific gaps in open-source AI, such as the lack of good training data that led to Together's RedPajama project and the still-underbuilt state of reinforcement-learning tools. He's also unusual in that he holds his Venture Partner role at Cadenza while still actively working as a founding engineer at Together AI, giving his investing perspective a direct, current connection to the frontier of AI infrastructure rather than being based on past experience alone.
