Venture and Angel Allocation
Rather than concentrating his bets, Marsan built a diversified portfolio across AI infrastructure, cybersecurity, and med-tech. He allocates capital based on stage risk, favoring seed and Series A rounds where he can add operational value beyond capital.
His investment methodology combines technical diligence with market timing indicators, focusing on sectors with clear regulatory tailwinds and strong moat potential. This approach has helped him maintain above-average returns even during downturns.
Asset Mix and Liquidity Management
Liquid and Illiquid Allocation
Marsan balances liquid instruments such as public equities, cash, and short-term bonds against long-dated private equity and real estate holdings. This structure ensures he can meet obligations without being forced to sell illiquid positions at adverse prices.
He also maintains a line of credit against certain portfolio companies, allowing him to increase exposure when market conditions favor aggressive deployment. Stress tests on interest-rate shocks are run quarterly to manage leverage risk.
