Or find every investor that fitsD3 lists 18 checked portfolio companies on its own site and is named in 4 funding rounds. Its most frequent entry is Series A, 75% of the companies with a known first round. Its largest themes are AI & Machine Learning (87%), Industrial & Manufacturing (7%) and Robotics & Hardware (3%). It invests most often alongside Lakestar, IQT and Lux Capital.

Round figures show recent activity, not D3's whole history. Rounds on record name 4 companies; its own site lists 18. Funding rounds are complete from mid-2025, so counts and the yearly trend undercount a firm that invested before then. The portfolio, themes and places come from its own site and are not affected.

Rates come from what VCinfo has observed since observation_start. Firms tend to remove companies that closed, so early rates understate reality. A company leaving a portfolio page does not mean it closed or exited. An unreachable site means our checks failed, nothing more.
