Executive Business Partner

About the team and role

The Executive Business Partner (EBP) provides direct executive support to the CMO and ensures the operational cadence of the Marketing organization is clear, aligned, and prioritized. You will be the trusted owner of the CMO’s time, information flow, and day-to‑day operating rhythm — operating at the intersection of a high‑visibility C‑suite function and a fast‑moving go‑to‑market organization. This means your work carries real stakes: the discretion you exercise, the judgment calls you make, and the quality of the support you deliver directly affect how one of Klaviyo’s most senior leaders shows up.

You will build toward proactive partnership by anticipating needs, solving logistical and scheduling challenges independently, and creating structure in ambiguous situations.

• Prepare and consolidate materials for key meetings so your leader is well‑briefed and able to focus on strategy rather than catching up in real time.
• Track action items and decisions from leadership meetings, proactively following up with owners to drive completion and reinforce accountability.
• Coordinate logistics and execution for team events, all‑hands meetings, board preparation cycles, and external appearances — including high‑visibility moments tied to the CMO’s external presence (e.g., conferences, analyst briefings, earnings‑adjacent activities).
• Serve as the primary point of contact and gatekeeper for the CMO, triaging inbound requests with sound judgment and a deep understanding of their priorities — protecting their time and attention with confidence while maintaining trust with the people who need access.
• Ensure the day‑to‑day and week‑to‑week schedule is logical, manageable, and aligned with the leader’s stated priorities.

This is not a traditional administrative assistant role — it is a high‑impact, visible, and fast‑paced position suited for someone who understands that supporting a C‑suite leader is a craft. You will earn trust through discretion, follow‑through, and judgment, and you will actively develop your executive partnership skills in one of the most dynamic functions at a hyper‑growth public company.

• Prepare and synthesize pre‑reads, decks, and briefing materials so your leader enters key meetings fully prepared — focused on the substance of the discussion, not on getting up to speed.
• Track action items and decisions from leadership meetings, proactively following up with owners to drive completion and reinforce a culture of accountability.
• Manage end‑to‑end logistics (scheduling, agendas, materials, tech, room/virtual setup) for leadership meetings, all‑hands, and team events, creating a seamless experience for all participants.

• Manage your leader’s calendar with a focus on prioritization and time protection — applying critical thinking to every request, defending focus blocks, and flagging low‑value items.
• Review the upcoming schedule in its entirety, proactively identifying conflicts, optimizing sequencing, and ensuring a sustainable and strategically aligned pace.
• Execute within an established operating cadence (e.g., staff meetings, MBRs, planning check‑ins), ensuring logistics are tight and the leader’s time is used well across each recurring forum.

• Serve as the primary point of contact and gatekeeper for the CMO, managing inbound requests with professionalism and sound judgment — elevating what warrants the CMO’s attention, handling what doesn’t, and ensuring the people who need access feel respected in the process.
• Build strong, trust‑based relationships with direct reports and key cross‑functional partners, becoming a reliable hub for communication and context.
• Attend selected meetings to capture notes, action items, and risks; provide concise, accurate summaries that keep your leader informed on topics they could not attend directly.
• Ensure timely and accurate flow of information to and from the leader’s office, eliminating bottlenecks and keeping key stakeholders well‑informed.
