Or find every investor that fits3Lines lists 24 checked portfolio companies on its own site and is named in 2 funding rounds.

Its largest themes are AI & Machine Learning (23%), Cybersecurity (15%) and Education (13%). 58% of its companies are based in United States. It invests most often alongside Stout Street Capital, Denver Ventures and Evolution-VC.

Round figures show recent activity, not 3Lines' whole history. Rounds on record name 2 companies; its own site lists 24. 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.
