a16z Big Ideas

Alex Immerman from a16z speedrun recently shared what he thinks the next big startup ideas look like.

Funny thing? He basically described Mindra.

For months, people have told us: “You’re too horizontal.” “Pick a narrower wedge.” “This should be more vertical.”

But here’s what gets missed:

Real value doesn’t come from isolated tools. It comes from coordination.

Real work is multiplayer. Multiple people. Multiple incentives. Multiple systems.

Horizontal isn’t a weakness when it’s the layer that connects everything. That’s where the leverage is.

2026 is going to make this obvious.
