A little-known private investment firm that has filed 13F reports with the SEC since 2009.
Life story
Triple Frond Partners is a private firm with almost no media coverage. We found no reliable public information about its founders, founding year or history.
How they got started
According to SEC EDGAR, the firm has filed 13F reports since February 2009. Filings from 2015–2020 were signed from a Seattle office by Charles F. Pollnow IV as manager of the firm. Its 2026 filings list a San Francisco address and name Hawk Hill Capital Partners LP as an other included manager.
Investment style
The firm does not publish its investment philosophy. Its 13F filings show a very compact portfolio of roughly a dozen US stocks, meaning capital is concentrated in a small number of companies.

What to learn from following the portfolio
- With little outside information, the 13F portfolio itself is the main source — watch which positions are held across many quarters.
- The portfolio is concentrated: each new position or sharp change in a stake can be a meaningful signal, but we do not know the reasoning behind it.
- 13F is 45 days delayed and shows only long US positions. Check each position's halal status in the Portfolio tab.
