## About

Duration AM is a fund-of-funds manager headquartered in London. The firm constructs multi-manager portfolios focused on venture capital, allocating capital across a curated set of underlying VC firms. By operating as a manager of managers, the firm layers its own due diligence and portfolio construction discipline on top of the stock-picking of its selected general partners. The firm's strategy centers on venture capital fund commitments, targeting generalist VC strategies across multiple stages and regions. Rather than competing with its underlying managers for direct deals, Duration AM aggregates exposure, seeking to smooth the volatility inherent in single-fund venture investing. The firm's mandate spans at least two geographic regions, with allocations to managers in both Europe and North America. Its approach does not typically include direct co-investment or secondary transactions, focusing instead on primary fund commitments. Scale and team specifics are not publicly disclosed, and the firm maintains a low profile with no significant public marketing footprint. Duration AM's operational cadence relies on manager selection cycles, with capital deployment dictated by the fundraising schedules of the underlying funds it backs. Its London base positions it within Europe's largest venture hub, providing proximity to a dense network of emerging and established fund managers.

## Questions

### How does Duration AM source the venture capital managers it backs?

Duration AM sources venture capital managers through a combination of longstanding GP relationships and systematic market screening. The firm evaluates emerging and established venture firms across Europe and North America, assessing team stability, investment discipline, sector focus, and historical return drivers. Selection emphasizes managers with a demonstrated ability to access competitive early-stage rounds and build concentrated portfolios.

### Does Duration AM invest directly in companies or only through funds?

Duration AM operates exclusively as a fund-of-funds manager, allocating capital to underlying venture capital funds rather than making direct company investments. This structure insulates its portfolio from single-company concentration risk and relies on the origination capabilities of its selected general partners. The firm does not maintain a direct-investment or co-investment program based on public record.
