## Questions

### Who makes investment decisions at Portia Investment Advisors?

Guy Wildon, the founder, is the sole decision-maker and principal. He is supported by an external network of venture partners and domain-specific advisors, but there is no investment committee — all deployment decisions are his own. This structure has remained unchanged since the firm's 2014 founding.

### Does Portia do any fund commitments or only direct deals?

The firm concentrates overwhelmingly on direct equity investments in early-stage companies. There is no public evidence of Portia acting as a limited partner in third-party venture funds. Wildon has maintained this direct-only approach to avoid the fee layering and diluted influence associated with fund-of-funds models.

### What is Portia's stance on follow-on funding for portfolio companies?

Portia reserves significant capital for pro-rata follow-on investments in its top-performing positions. Wildon has described maintaining ownership percentage through subsequent priced rounds as central to the strategy, particularly in companies where Portia wrote the first institutional check.
