# E2B

## Profile
E2B is a startup providing sandboxing infrastructure for AI agents, notable for its **ephemeral** architectural bet. Sandboxes are treated as disposable: spin up to run a task, then immediately tear down. Built on **Firecracker microVMs**. Y Combinator–backed. Has raised approximately **$32M**. Canonical site: e2b.dev.

## Layer placement
[[concept-layer-1-compute]] — Compute & Sandboxing. The ephemeral pole.

## Strategic contrast
The direct architectural counterpoint is [[entity-daytona]], which takes the persistent sandbox bet (long-lived environments where agents install dependencies and maintain state). The choice between them is a core architectural decision for any agent system, not a style preference.

## Why it appears in this source
E2B is the speaker's canonical example of ephemeral sandboxing. It illustrates that even the most mature layer of [[concept-the-agent-stack]] still has fundamental architectural splits.
