About the role

Founder's Associate role joining the Office of the CEO as part of the founding team, focusing on high-priority strategic initiatives, cross-functional execution, and building the early team as the company grows.

Responsibilities

  • Take on the CEO’s highest-priority problems directly — strategic projects, market research and competitive work, financial analysis, and cross-functional execution, often with no existing playbook
  • Identify problems, develop solutions, and execute them; often working on multiple initiatives
  • Build and own the models and analyses that inform major company decisions
  • Collaborate with and move fluidly across various departments as business priorities shift
  • As the early stages of this team grows, you will help recruit, ramp, and manage the associates who join after you

Qualifications

  • 3–5 years in top-tier investment banking (TMT/fintech coverage), private equity, management consulting, late-stage venture capital, or a fast-growing startup
  • A track record of outperformance — clear signals you were trusted with more scope, faster, than your peers
  • Strong quantitative and analytical skills: advanced Excel, working knowledge of SQL, and comfort dissecting messy data and building models from scratch
  • Extreme rigor and comfort operating in ambiguity at speed — priorities here change faster than the plan does
  • Demonstrated ability to sustain a high-intensity pace: this role will regularly require ~12-hour days, 5–6 days a week, especially in year one
  • This role is based in Miami or NYC but will involve travel
