Our method
Select with conviction
We examine the team, the market, traction and financing needs. Our analysis sets out the reasons to invest and the risks that could challenge our conviction.
Negotiate the terms
Valuation, dilution, investor information and exit conditions: we work on the terms that matter, seeking a lasting balance with founders.
Support over time
We track key metrics and financing milestones. Depending on each company's needs, we draw on our experience and our commercial, financial and operational network.
Prepare decisive milestones
New round, industrial partnership or sale: we get involved in the moments that determine the value of the investment.
