Multi-venture portfolio operations
Cross-venture routing, shared agents, isolation rules — running 3+ ventures from one operator.
Why portfolios collapse without isolation
Running multiple ventures from one operator is feasible — agents do most of the heavy lifting per venture, the operator routes between them — but only if context is isolated rigorously. Without isolation, every session risks pulling the wrong venture’s assumptions into the answer. The errors are subtle, often plausible, and hard to catch on the way out.
The default failure mode is bleed, not collision. Pure collision (Venture A’s data showing up labeled as Venture A’s data in a Venture B answer) is rare and obvious. The common failure is bleed: assumptions from one venture quietly shape an answer about another, and you don’t notice until the wrong decision propagates.
Three structural moves prevent most of this. Per-venture working directories. Venture-tagged cross-venture agents. Operator-side explicit context switching. The lesson below is each in detail.
The three-axis isolation model
Each axis covers a different leakage path. All three need to be in place for the portfolio operation to be reliable.
| Axis | What it isolates | Implementation |
|---|---|---|
| Working directory | Project files, CLAUDE.md, memory, session context | One directory per venture; agent loads only the active venture’s context |
| Cross-venture agents | Specialists that serve all ventures (legal, finance, chief of staff) | Brief requires venture tag at session start; venture-specific facts in venture CLAUDE.md |
| Operator discipline | Mid-session context switches | Explicit verbal/typed venture tag on switch; mechanical reinforcement via session-start hook |
The first axis is the heaviest lift (refactoring directory layout, splitting CLAUDE.md files) but the highest leverage. The other two are cheap upgrades on top of a working first axis.
