About Sébastien

Are you the CEO of a growing tech startup looking for a financial right-hand to structure your management, prepare for fundraising, or professionalize your investor reporting?

As a Fractional CFO and Founding Partner at Iter Advisors, I have been supporting tech companies (SaaS, AI, Deep Tech, FinTech, e-commerce) from pre-seed to Series B for over 12 years in their financial structuring and scaling, in Europe and the USA.

What I have already done:
  • 85+ tech clients supported, team of 15+ finance experts at Iter Advisors
  • €50M raised (Solarmente), €3M+ equity/non-dilutive (Equito), €2.5M debt (NuuBB)
  • Financial management of Happy Scribe (€7M ARR, bootstrapped, 45+ employees), Impact+, NuuBB, Rubiko, Emerald Stay...
  • M&A management: acquisition of Eltex (50 to 110 employees)
  • Finance stacks: Pennylane, Stripe, Payhawk, Payfit, Finthesis, Agicap, Qlik, Tableau...
My services:
  • Financial management: P&L, cash flow, budget, forecast, treasury
  • Business plan and financial modeling: scenarios, valuation, SaaS unit economics (ARR, LTV/CAC, NRR, Rule of 40)
  • Fundraising: pitch deck, data room, due diligence, investor negotiation
  • Investor reporting: board pack, monthly KPIs, dashboards
  • Financial structuring: accounting processes, management control, team training
  • ERP and finance tool integration adapted to your stage

Why me instead of a traditional CFO?

I'm not just a CFO who advises. I am an operational business leader who has experienced growth from the inside (CFO at Carts Guru for 4 years, then Founding Partner of Iter Advisors, 85+ clients tech).

I speak the language of founders, investors, and boards.

DSCG + Master's in International Finance (Carlos III of Madrid). FR/EN/ES.

Based in Barcelona, serving France and Europe.
