About the role

This is a critical role, supporting the CEO through exceptional growth (we grew 12x last year & have already grown another 5x so far in 2026).
This is a no egos role; you'll preempt the need & jump into every task, acting as the CEO's right hand as we hit this next phase of growth.
In return, you'll be entrusted with the most critical insights into running our business, a front seat at a true hypergrowth startup.

Own the CEO's calendar end to end - scheduling, sequencing, protecting focus time, and making the hard prioritization calls about what earns a slot.
Build and maintain a lightweight "CEO operating system": weekly priorities, open loops, follow-ups, reminders.
Coordinate with EAs and chiefs of staff at partner, customer, and investor organizations.
Coordinate appointments, household services, purchases, deliveries, family travel, and other personal administration so they slot cleanly around professional priorities, and build systems that make the CEO's life admin run without their attention.

Proven experience supporting c-suite executives in the fastest paced environments.
The ability to preempt a need and to fill that need, without explicit direction.
you are relentlessly focused on delivery.
Strong judgment and prioritization instincts: you know what matters most, and why.
Exceptional written communication, including the ability to write clearly in someone else's voice.
Comfort with ambiguity, shifting priorities, and a company that looks different every quarter.
Fluency with modern tools (Google Workspace, Slack, Notion, Linear) and a strong understanding of how a tech startup operates.
Comfort supporting both professional and personal logistics.
You wait for direction when you can see that something needs to be done.
You are uncomfortable handling personal logistics or operational tasks.
