# Use Structural Separation to Engineer Commitment

## Action: Use Structural Separation to Engineer Commitment

**Do:** Establish new ventures in highly competitive markets as **legally separate entities** to eliminate resource redeployability.

**Expected outcome:** Creates a credible signal of 'do-or-die' determination, deterring rivals from assuming you will easily retreat.

### How to run it

This is the operational form of [[concept-structural-separation-commitment]] and the exit-ramp for Gate 3 of the [[framework-market-entry-evaluation]]. Lock talent, capital, and IP inside an entity whose governance prevents casual re-absorption into the parent — the way [[entity-microsoft-d1]] did with [[entity-openai-d1]]. The point is to *destroy your own retreat option* so rivals cannot bank on your withdrawal ([[concept-commitment-paradox]]).

**Caveat (enrichment):** structural separation is the strongest commitment device, but not the only one — contracts, visible sunk investments, and domain-tied governance can also signal commitment without full legal carve-out.
