Coinbase has appointed longtime engineer Rob Witoff as its new chief technology officer.
The appointment was announced by CEO Brian Armstrong, who praised Witoff's contributions to the company's growth, describing him as the driving force behind making Coinbase "one of the most AI-enabled companies in the world."
From early Bitcoin builder to CTO
Witoff revealed that he has officially begun his "next tour of duty" as Coinbase's CTO. His storied crypto journey started with his fascination for Bitcoin in 2009 and led him to join the crypto exchange as an engineer in 2014.
Witoff noted that the company initially ran on Heroku, supported just a single cryptocurrency, and operated from one codebase with a small engineering team. Despite the dramatic transformation over the past 12 years, he said the company's core culture has remained unchanged, describing Coinbase as a team that continues to "relentlessly ship" products in pursuit of its mission.
. He added that his mission as CTO is to make Coinbase "the best place in the world to build."
Armstrong highlights AI leadership
Armstrong welcomed the appointment by stressing Witoff's role in shaping Coinbase's engineering organization and AI strategy.
According to the Coinbase CEO, Witoff has played a major role in the company's success over the years. He has been central to its emergence as one of the world's most AI-focused technology companies. Armstrong added that Coinbase is fortunate to have him taking over the CTO position as the company enters its next phase of growth.
Witoff's promotion comes amid one of the most significant periods of organizational change in Coinbase's recent history.
The executive first rejoined Coinbase in December 2024 as Head of Platform and a member of the executive team.
An AI-first company
In 2026, Coinbase accelerated its transformation into what Armstrong has called an "AI-first" company. In May, the exchange announced a restructuring that included cutting approximately 700 employees, or roughly 14% of its global workforce, while flattening management layers and reorganizing teams around AI-assisted development.
The leadership shake-up continued in July when Chief Legal Officer Paul Grewal announced his departure after six years leading Coinbase's legal strategy and its high-profile regulatory battles.
