## Questions

### Who makes the investment decisions at Seaplane Ventures?

All investment decisions are made by Joe Magyer, the Founder and Managing Partner. He built the firm as a solo general partner after managing nearly A$1 billion as CIO of Lakehouse Capital in Sydney. Before that, he was a full-time angel investor, a background that shaped his concentrated, high-conviction approach.

### What stage and check size does Seaplane Ventures typically target?

The firm explicitly targets seed-stage US startups, with a focus on providing a startup’s first outside capital. Public materials do not state a fixed check size, but its positioning as a first-check investor and co-investor alongside lead VCs points to pre-seed and seed rounds where checks can range from a few hundred thousand to low single-digit millions.

### Is Seaplane Ventures a fund or an angel syndicate?

Seaplane operates as a venture capital firm, not an ad hoc angel syndicate. However, its solo-GP structure and willingness to co-invest in rounds led by other VCs make it operationally closer to a permanent-capital angel vehicle than a traditional multi-LP seed fund. The firm has not disclosed a specific fund vintage or vehicle structure publicly.
