CTO

Ryan Mahoney

Ryan Mahoney

Director of Product, FirstWho

“The toughest part of hiring a scaling CTO is finding someone who builds structure without killing momentum. Most candidates have only experienced either total chaos or heavy bureaucracy. You need a leader who can build an internal developer platform to help engineers focus but also admit when a process is slowing things down. They must have the courage to stop product decisions that threaten stability while keeping the CEO on board. If they cannot communicate clearly across teams, the strategy will fail no matter how brilliant they are technically.”
