Brett Harrison — FTX US former president speaks out

I flew out to Chicago to interview Brett Harrison, who is the former President of FTX US President and founder of Architect. In his first longform interview since the fall of FTX, he speak in great detail about his entire tenure there and about SBF’s dysfunctional leadership. He details how the inner circle of Gary Wang, Nishad Singh, and SBF controlled the codebase, mismanaged the company, got distracted by media, and even threatened him for his letter of resignation. In what was my favorite part of the interview, we also discuss his insights about the financial system from his decades of experience in the world's largest HFT firms. And we talk about Brett's new startup, Architect, as well as the general state of crypto post-FTX. After talking with Brett for 3 hours, I found him to be extremely intelligent, thoughtful, and ethical.

WHAT IT’S REALLY ABOUT

Inside FTX: Brett Harrison on Sam, dysfunction, and rebuilding crypto

Brett Harrison, former president of FTX US and ex-Citadel/Jane Street executive, recounts how he joined FTX, what he observed internally, and why he ultimately resigned months before the collapse. He describes a technically strong but dangerously centralized codebase, an organization dominated by a tiny Bahamas-based inner circle, and a CEO increasingly consumed by PR and politics rather than management. Harrison details his attempts to push for governance, staffing, and structural reforms, the hostile response to his ultimatum letter, and how the subsequent fraud revelations blindsided him despite serious organizational red flags. He also explains his new company, Architect, which aims to provide unified, institution-grade infrastructure for trading across centralized and decentralized digital asset venues.

IDEAS WORTH REMEMBERING

5 ideas

Concentrated technical control is a massive organizational risk.

At FTX, 90%+ of the core code was written by two developers, making the system effectively dependent on a couple of people and almost impossible for others to audit, extend, or safely maintain—exactly the opposite of robust, scalable financial infrastructure.

Charismatic PR can mask deep governance and management failures.

Sam Bankman-Fried’s constant media presence and cultivated ‘boy-genius’ image created a reputational flywheel with journalists, investors, and politicians, which helped obscure internal dysfunction, neglect of day-to-day management, and resistance to basic organizational reforms.

Red flags in management don’t automatically imply fraud—but they matter.

Harrison repeatedly raised concerns about under-staffing, centralization in the Bahamas, and Sam’s inattention; while he did not infer fraud, he concluded he couldn’t fulfill his responsibilities under those conditions and chose to document his concerns and resign.

Even sophisticated insiders can’t easily detect well-concealed financial misconduct.

Given falsified internal records, audited financials, and strong apparent revenue from observable trading volumes, Harrison argues it would have required distrusting auditors, investors, and public data simultaneously to suspect a hidden hole—underscoring the limits of individual due diligence inside a deceptive organization.

Crypto market structure remains immature compared to traditional finance.

Despite some exchanges (like FTX) offering relatively clean APIs and margining systems, Harrison notes that many venues have inconsistent behaviors, slow or opaque settlement, and fragmented liquidity—leaving room for dedicated infrastructure providers like Architect.
