We’re building one of the most elite GTM organizations in tech and we’re looking for a world‑class Executive Assistant to help scale it.

This isn’t your typical EA role. You’ll be the operational right hand to our SVP of Sales. Think: calendar control, travel orchestration, strategic meeting flow, and the glue between Sales, Success, and the broader business.

You’ll bring clarity to chaos, momentum to motion, and structure to speed, ensuring the GTM team is always pointed at the highest‑leverage work.

Partner closely with the CRO and GTM leaders to prioritize time, focus, and energy across meetings, customers, internal stakeholders, and strategic initiatives.

Own and optimize complex calendars, across time zones, with ruthless prioritization.

Coordinate cross‑functional meetings, off‑sites, QBRs, and field events and ensure they land with impact.

Handle executive travel, logistics, and briefings like a pro, details matter.

Create leverage across the GTM org by helping drive action items, follow‑through, and internal alignment.

Manage ad hoc requests with speed, confidentiality, and judgment.

You’ve supported senior leaders (CRO, Sales, GTM, or C‑suite) in high‑growth, high‑performance environments.

You love solving problems before they’re visible - you’re proactive, not reactive.

You’re polished but scrappy, someone who brings professionalism without over‑engineering.

You’re organized under pressure, resourceful when things get chaotic, and always one step ahead.

You’re based in London and thrive in a fast‑paced, in‑office environment with exec visibility.

This is a rare opportunity to plug directly into a GTM engine that’s scaling at lightning speed. You’ll be the connective tissue across Sales, Success, Marketing, and Ops, helping the team move faster, smarter, and with more precision.

If you’ve ever wanted to see how a category‑defining company grows from the inside out — this is it.
