• Executive Communication Prep: Serve as a sounding board and verbal partner for the C-suite, helping structure, refine, and prepare high-impact internal messages and leadership updates.

• Travel & Logistics: Organize seamless domestic and international travel, including itineraries, visas, conference access, and emergency adjustments on the fly.

• Board & Leadership Meetings: Prepare agendas, collate board decks with executive inputs, take precise minutes, and track actionable post-meeting deliverables.

• Extreme Discretion: Natural handling of highly sensitive business IP, hiring plans, and investor relations with strict confidentiality.

• Adaptability in Ambiguity: Comfortable operating in a high-velocity, evolving environment where priorities shift quickly.

Nice to Haves & Perks:
