She studied the human mind at Berkeley. Now she manages the chaos of a tech CEO's day - which, if you think about it, is applied psychology.
When a 140-person company moves at startup speed, somebody has to make sure the person at the top is in the right room at the right time. At CodeSignal, that somebody is Katie Boyer.
Boyer is the Executive Assistant to Tigran Sloyan, the co-founder and CEO of CodeSignal - the San Francisco company that turned the dreaded technical interview into a measurable, AI-assisted science. Her name does not appear on the product roadmap. It does not show up in funding announcements. And yet the calendar, the inbox, the travel, the back-to-back days that make a venture-backed CEO's life function - all of it passes through her hands.
The job title is modest. The leverage is not. An executive assistant to a founder is the difference between a CEO who is present and a CEO who is perpetually behind. Boyer is the quiet infrastructure underneath a loud company.
The most valuable person in the room is often the one taking notes in it.
- on the EA's quiet powerMost careers stay in a lane. Boyer's reads like a tour of unrelated planets - and that is exactly the point.
She started at the Alzheimer's Association of Northern California and Northern Nevada, where she joined in 2015 as a Program Administrative Assistant. The role was meant to be data collection and office operations. It did not stay that way. Before long she was training other regional offices on their own procedures and overseeing volunteers. That is the tell: hand Boyer a defined role and it quietly expands until she is the person everyone else relies on.
From mission-driven nonprofit work she crossed into money. At Decker Retirement Planning she served as Operations Manager and Executive Assistant - learning the rhythm of a business where precision and trust are the entire product.
Then came the trading floor. In 2020 she joined Coatue Management, the technology-focused hedge fund known for its $20B-plus war chest and its bets on the companies reshaping the internet. Supporting executives at a firm like that is a contact sport - high stakes, low margin for error, zero tolerance for a dropped ball.
In 2021 she landed at CodeSignal, the same year the company closed its $50M Series C. The throughline across Alzheimer's research, retirement planning, hedge funds, and an AI hiring startup is not the subject matter. It is her: the ability to walk into any operation and become its load-bearing wall.

Operations Manager and Executive Assistant. Learned a business built on precision and client trust.
Executive Assistant at the technology-focused hedge fund - high stakes, no margin for error.
Executive Assistant to co-founder and CEO Tigran Sloyan, supporting the company through its growth as an AI-driven assessment platform.
CodeSignal builds technical assessments and hands-on simulations that let companies hire engineers on demonstrated skill instead of a gut feel from a whiteboard.
The platform leans hard into AI - including an AI tutor and role-play tooling - to coach and evaluate candidates. Boyer supports the CEO of a company whose product interviews software engineers for a living.
CodeSignal raised a $50M Series C in September 2021 - the same season Boyer arrived - pushing total funding to roughly $87.5M. Headquartered at 201 California Street, San Francisco.
Nonprofit, finance, hedge fund, AI software - she resets to a new domain without losing a step.
The whole job runs on trust. She is the person who knows everything and says nothing.
Give her a narrow role and watch it grow until she is indispensable - the Alzheimer's Association learned this first.
She earned a psychology degree from UC Berkeley, then built a career reading and managing the days of demanding leaders. Call it applied psychology with a calendar.
Her resume touches four worlds that rarely share a guest list: Alzheimer's research, retirement planning, a multibillion-dollar hedge fund, and an AI hiring startup.
She goes by Katie Boyer now and Katie Waggoner before - but across every chapter, the calendar kept running on time.
