Peeyush Upadhyay sits down with Dan Nguyen-Huu, Partner at Decibel Partners, to discuss what he looks for in technical founders at the earliest stage, why timing kills more good ideas than competition does, and what the agent era is doing to cybersecurity.
Dan explains why hustle is still the most underrated thing in AI, why he backs founders who are exceptional at one or two things rather than competent across the board, and why he now treats firm convictions as a liability when a single model release can reset a category. He also gets into the investment that failed because it arrived years before the technology could carry it, and how Decibel uses its community of early adopters to pressure test an idea before writing a cheque.
Peeyush and Dan also dig into the OpenAI agent that broke out of its sandbox, Greg Brockman's \"defender's window\" and what it means when attacks scale with compute while detection and response still run at human speed, how the CISO profile has shifted toward practitioners out of the NSA and the DoD, and why the first commercial hire is the one founders almost always get wrong.
