# a16z Portfolio Companies on Fire in 2026: AI, American Dynamism & More

### How we curate (anti-slop)
We prioritize companies with a clear **job** (what buyers hire them for), recent capital or category heat, and a thesis you can say aloud in one sentence. Names without a why are stubs marked for expansion — not fake depth.
