Fractional CFO | Seed & Series A Startups

Former founder, 2x startup CFO (SaaS, Web3), venture capitalist, and Techstars advisor. I partner with early-stage founders to bring financial clarity, prepare for fundraising, and build the operational foundation for growth.

👉 If you’re a founder preparing to raise capital or scale, I’ll help you put financials, strategy, and investor readiness on solid ground so you can focus on building.

Who I Work With

Seed and Series A startups that need CFO-level guidance but don’t yet have the budget or workload for a full-time hire. Most of my clients come to me when:

  • • Coaching founders to pitch to investors and committees
  • • Strategic planning around GTM, product/market fit, and growth


Proof & Results

  • • Built financial models and data rooms that secured funding from angels, VCs, and foundations (including a $100K Rockefeller Foundation grant)
  • • Led finance for a Series A Web3 startup, launching a multi-million-dollar token and DAO
  • • Supported a Techstars startup in securing $300K in angel funding and admission into the accelerator
  • • Cofounded and scaled a consulting firm that raised €20M+ for impact startups


Credibility & Background

  • • Forbes 30 Under 30 (Finance, Europe & Spain)
  • • 10+ years working with early-stage startups, VCs, accelerators, and funds
