## Questions

### How does Pioneer Square Labs source its deals?

PSL sources deal flow through two channels: internal company creation inside the startup studio and traditional venture investments in external founders. The studio team generates and stress-tests ideas, then recruits operators to run the most promising concepts as standalone companies. This manufactured pipeline accounts for a material share of the portfolio and gives PSL founder-level entry terms that a conventional seed fund cannot replicate.

### Is Pioneer Square Labs a venture fund or a startup studio?

It is both. PSL operates a startup studio that builds companies from scratch and a venture capital fund that invests in them at formation, alongside selective investments in external early-stage companies. The dual structure means PSL earns returns as both a founder and an investor, a hybrid economics profile uncommon among Pacific Northwest venture firms.

### Who makes investment decisions at PSL?

The four managing directors — Greg Gottesman, Geoff Entress, Vivek Ladsariya, and T.A. McCann — lead investment decisions. Operating Partner and CFO Palvi Mehta handles finance and portfolio operations. Venture partners Julie Sandler and Ben Gilbert contribute to sourcing and diligence but do not appear to sit on the formal investment committee.

### Does PSL invest beyond Seattle?

Yes. While PSL is rooted in Seattle, the firm lists additional office locations in Austin, Portola Valley, Bala Cynwyd, Boise, and Stamford. The geographic spread supports a Pacific Northwest-heavy but not exclusively Seattle-bound investment footprint, with engineering talent drawn from startup hubs across the western US.

### What is Lev, and how does it relate to PSL's investment strategy?

Lev is an AI tool PSL built to encode the studio's idea-generation and validation playbook. It uses language models to generate startup concepts, assess market potential, and surface the strongest candidates for studio incubation. The technology effectively productizes part of PSL's origination engine, and the firm has commercialized Lev as a tool for entrepreneurs and corporate venturers outside its own portfolio.
