What is a C-suite executive assistant?

A C-suite executive assistant supports the most senior leaders in an organization, typically CEOs, CFOs, COOs, and CMOs. These roles require a different level of support than department heads or mid-level VPs. They’re often the connective tissue between strategic decisions and operational execution.

Here are some success stories from CEOs and other C-level executives who talk about how they leverage their C suite executive assistant. 

A C-suite executive assistant goes far beyond organizing calendars and inboxes: they orchestrate the executive’s entire operating rhythm. They act as an extension of the executive’s judgment, priorities, and style.

They’re responsible for managing:

• Board prep and investor follow-up
• Multi-party scheduling across time zones
• Cross-functional coordination
• Stakeholder and customer communications
• Calendar optimization and briefing packs

According to Gartner, 56% of C-level executives are likely or extremely likely to leave their role within the next two years. There are many factors behind this surge, but one thing is clear: the scope of responsibility for a single executive continues to expand. 

According to the same report by Gartner, executive workload has risen significantly compared to two years ago. Today, 67% say they are expected to do more in their role, 58% report that their organization relies more heavily on their function or business unit, and 44% feel increased stress due to work responsibilities.

So, how can C-level executives deliver all the work that’s expected of them and stay put? The answer is not to reduce their workload, since the work has to get done one way or the other. The solution is much simpler than that: hire a C suite executive assistant who can support three executives at once and help them catch up with everything that has been falling through the cracks.  

There are many ways to pair an EA with some of your leaders. Here’s how team leads from MongoDB, Datadog, and Notion have built the executive support function at their orgs.  

How is C-suite EA support different from other EA support?

Supporting the C-suite demands speed, discretion, and strategic judgment. These assistants are not simply ordering lunch or flagging important emails; they operate at the same caliber as executives normally would, make decisions, and help move the KR forward while they’re busy handling other priorities. Let’s see how that works for a CHRO: 

Before: The executive has to schedule interviews with dozens of candidates, check their email multiple times a day to stay up to date with candidate updates, and monitor the onboarding of new hires to set them up for success.  Executive energy is spent on reactive problem-solving.

After: The executive assistant to the CHRO manages key stages of the recruiting process, including coordinating hiring efforts, conducting initial interviews, and preparing comprehensive pre-meeting briefings. This ensures their leader arrives at the final interview fully prepared, while investing only a fraction of the time typically required.

At Viva, training is a structured 4-week process. By the time you hire a C-suite executive assistant from Viva, they already have all of this knowledge and are ready to deliver impact: 

Week 1: Tools and email management

• Slack, Notion, Google Workspace, Canva, Chat GPT, Magical, Eisenhower Matrix, Microsoft 365, and Zoom
• Inbox zero, email etiquette, and categorizing emails
• Outlook, Gmail, Superhuman

Week 2: Calendar and meeting support

• Calendar management and calendar compartmentalization
• Leading meetings and town halls, note-taking, transcription, and meeting prep (Pre-Meeting Briefings)
• Creating presentations and agendas

Week 3: Travel, event planning, and expense management

• Best practices on travel research and flight booking
• Event planning, team engagement, and offsite planning
• Budget management, vendor relationship management

Week 4: Operations and special projects

• Board meeting support, reporting, playbook creation, OKR tracking and follow-up, project management, creating company-wide workshops, and building SOPs
• Role-plays based on real scenarios
• Final assessment

“Andrea is proactive about thinking through how she can help and suggesting where she can add more value.” — Rachel Hepworth, CMO, Notion

What changes in week 1 with a C-suite executive assistant?

Most of our end users report seeing impact within the first week of onboarding a C suite executive assistant, whereas other execs mention seeing impact instantly. If you’re wondering how you can get instant impact, read Placemakr’s success story and see what a single EA did for the CEO and the President in just 24 hours. 

In week 1, your C-suite EA focuses on:

• Shadowing key meetings to observe your dynamics
• Understanding your rhythm, decision style, and time use
• Mapping recurring workflows, including staff meetings, investor updates, and internal reporting

Immediate improvements:

• You stop getting interrupted during your focus time with questions that could wait 
• Your EA flags which meetings to prep for, delegate or skip
• You notice that Slack and email communication start to feel filtered, not chaotic

“Martina has been serious leverage. She picks things up pretty quickly and has made my life easier.” – Christopher Williams, Sr. Director, Strategy, Real Estate Partnerships, Placemakr

What happens in week 2 of C-suite EA onboarding?

By week 2, your C-suite executive assistant begins owning workflows, handling tasks like:

• Drafting agendas and backgrounders for exec team meetings
• Coordinating external calls with investors, partners, and customers
• Prepping decks or briefings with relevant materials (pulled from Slack, Notion, or prior docs)

They also establish routines that protect your energy:

• Defining “no-meeting zones”
• Introducing priority tagging in Superhuman or Gmail
• Creating briefing templates so you always walk into meetings prepped

“Viva saves me 2-4 hours per day easily. Love working with them.” – Sean Kelly, General Partner, FamilyFundVC

How does a C suite executive assistant support impact in month 1?

By the end of month 1, the C suite executive assistant isn’t just helping; you’re operating differently:

• You’re not chasing updates or prep materials anymore
• You’re spending less time in back-to-back meetings and more time on strategic work
• You’re managing stakeholders and board prep without  late-night scrambles

The EA to the CEO at Gridwise started getting trips approved in just three clicks. No more back-and-forth conversations over Slack or email. This is how she did it. 

In another example, the executive assistant to the VP of Strategy and Development at Veho began distilling his entire inbox into a single Slack message each day. This allowed him to clear emails in minutes without even opening Gmail. To see how else she supported this VP and the CFO, read our blog on the importance of having an EA with a figure-it-out ability.

These are just two examples of what a C suite executive assistant could do for you, not just what they do by default. The true potential of a top-tier executive assistant lies in their ability to create impact where you need it most. They adapt, evolve, and transform alongside your priorities, consistently delivering work at the highest level of quality and strategic value.

How do C-suite EAs handle complexity at scale?

The C-suite level isn’t about doing more; it’s about doing what matters most.

C-suite EAs:

• Schedule across global time zones and hybrid teams (think: a CFO in San Francisco, a COO in London, a board chair in Dubai)
• Manage sensitive access and comms (including PII, financials, and board materials)
• Coordinate with legal, finance, and HR on behalf of the executive
• Own follow-through after investor calls and strategic meetings

They also adapt quickly. Since the rotation of C-level executives can be high, a lot of Viva EAs have adapted from one leadership style to another in a matter of days. Having an EA ingrained in your company can be a great way to onboard a new member of the leadership team: they can immediately support from someone who knows the ins and outs of your org. 

What outcomes can C-suite executives expect?

Observable outcomes include:

• Less context switching: Executives regain 5–15 hours per week for strategic thinking
• Higher-quality meetings: Agendas, goals, and follow-ups are consistent
• Greater team velocity: The EA chases follow-ups, not the exec
• Improved cross-functional communication: With clear briefings, timelines, and stakeholder visibility

According to Deloitte, 68% of respondents say they lack uninterrupted time to focus, and 41% of time is spent on work that does not contribute to organizational value. If a company is willing to pay a C-level salary, they might as well make sure that the C-level executive is hyper-focused on the most impactful work they can produce.

A well-trained C suite executive assistant can take care of the busy work so executives focus on what they do best.

Why work with Viva instead of a recruiter or staffing agency?

A recruiter for executive assistants can find resumes, but they don’t guarantee fit, readiness, or longevity.

An executive assistant staffing agency might fill a seat, but it rarely provides follow-through, training, and context on how modern enterprise teams operate.

Viva is different.

Unlike an executive assistant staffing agency, we provide:

• Full-time, remote C-suite executive assistants
• Pre-vetted, enterprise-trained professionals
• Structured onboarding, executive-matching, and documentation
• Ongoing coaching and feedback loops with Customer Success Managers
• Best-in-class security, continuity, and quality control you can count on

And we work with orgs from 20 to +5000 employees, across fintech, life sciences, climate, and more. If you’re thinking about hiring a C suite executive assistant, talk to our team. They’ll find the best fit for your organization.
