Written insights from the recorded portfolio, with the evidence linked below.

01

02

Separate activity from reputation

5 first company relationships appear in the latest 24 months, compared with 8 in the preceding window. The latest recorded investment is 2025-12-10. This describes observed activity through 2026-05-22; it does not establish current availability.

Explore the evidence ↗
03

Plan the next financing step

14 of 29 companies with a full 24-month observation window raised another equity round. This investor backed 1 of those companies again within that window. The difference is a reason to research the wider syndicate, rather than assume the same investor will fund the next round.

04

Use a specific point of relevance

Artificial Intelligence is the largest displayed sector by company count, appearing in 7 portfolio companies; sector tags overlap. 2 first entries carry a recorded lead flag and the median first-round syndicate includes 7 other named backers. Shared rounds are evidence of co-investment, not evidence of an introduction route.
