Outsourced CFO Start-up — Senior CFO for your Growth & Fundraising Phases
You have validated your business model. Your growth is accelerating. The next decisions — financing, recruitment, internationalization — will shape the future of your company. You need a senior CFO. Not full-time. Now.
Why hire an outsourced CFO?
Why a start-up needs an outsourced CFO
In the early years, it is often the founder who manages the finances with the help of an accountant for legal obligations. This model quickly reaches its limits as growth accelerates.
The concrete risks without a structured CFO:
- Miscalculated runway — you find out too late that the cash won't last 12 months
- Fundraising prepared without a solid financial model — investors pass
- Unformalized SaaS metrics — ARR, MRR, LTV/CAC absent from reports
- Unanticipated working capital in the scaling phase — growth consumes more cash than it generates
- Insufficient data room for due diligence
What our outsourced CFO concretely brings to a start-up
A VC-ready financial model
Construction or redesign of the financial model: growth assumptions, projected P&L, cash flow plan, sensitivity analysis. Your investors receive a solid file.
Monitoring of runway and key metrics
A structured data room for due diligence
Support for investor relations
Preparation of financial board decks, tracking of post-funding KPIs, monthly reporting to shareholders. You communicate with clarity and credibility.
Cash management during the scaling phase
When growth accelerates, working capital explodes. The outsourced CFO anticipates cash needs, structures financing lines, and secures your growth trajectory.

Your questions
FAQ Start-up
The natural trigger is the preparation for a fundraising or reaching 10 employees. Before this stage, a flash diagnosis is enough to lay the groundwork. After a Series A, a structured monthly fee becomes essential to meet your commitments to investors.
Yes. Our CFO can participate in meetings with VCs, answer due diligence questions, and ensure follow-up on negotiations. He becomes your credible financial contact with investors.
A freelance CFO generally intervenes on a defined mission on a temporary basis. Our outsourced CFO integrates into your team over the long term, with continuity of follow-up and a global vision of your trajectory. The dual expertise of CFO + Digital from Advanced Conseil also brings the ability to implement concretely — not just to advise.
Your accountant ensures legal and tax compliance. But building a VC-ready financial model, monitoring the runway, SaaS metrics, and investor reporting far exceed their usual scope.
