Yoon Auh spent a decade building trading systems before landing on the program trading desk at Credit Suisse, becoming head trader, then VP at Goldman Sachs, then head trader at Magnetar Capital — where he accidentally invented what became an entire sub-industry on Wall Street. Then he walked away from institutional finance to solve a problem nobody else would touch: your data is Big Tech's product, and they'll never change that. He spent three years and his own money building the answer. Now he holds 14 patents.In this episode, Yoon breaks down the mechanics of quant trading that textbooks skip, the dirty truth about government grants and military contracts, and why Signal, ProtonMail, and every other privacy app is solving the wrong problem.We cover:College grad → Credit Suisse → Goldman VP → Magnetar: the real pathIndex arbitrage, basket trading, and what institutional execution actually looks likeWhy quant models blow up in small caps (the bid-ask spread they never mention)Soft dollars: the hidden Wall Street system that funds research analystsWhy the biggest money is never in trading — it's in buildingFinfluencer scams then and now: the fax machine fraud that moved to the internet"When I say I want to go to Florida — then I see an ad for flights to Florida"Why Big Tech will never build real privacy tools (it's antithetical to their business model)The Nut Capsule: encrypted data objects that stay protected outside the appHow BOLTS beats Signal at file sharing — and why Signal stops at messagingUS military grants: SBIR, AFWERX, In-Q-Tel, and how to actually get fundedIsraeli and Canadian firms charging Americans to navigate US military grant applicationsOnly 25% of grant success is merit — a Navy acquisition officer said it on stagePalantir, Google Earth, and why the CIA funded the biggest tech companiesWhy you can't be the same politician you were when you startedMentorship, relationships, and the Goldman Sachs backup that saved the departmentGUEST:Yoon Auh: Founder & CEO of NUTS Technologies and BOLTS Technologies.
