Memory Portability Premium

Memory Portability Premium is the practice of valuing an agent memory layer by what survives the exit, not by what it does on day one. Every connector in this category stores something an agency paid to learn: client architecture decisions, brand constraints, debugging discoveries, campaign rulings. If that store exports as clean, structured, attributable records, the knowledge compounds across tools and staff turnover. If it exports as an opaque blob, the agency rents its own institutional memory and repays the learning cost at every switch. The premium is the delta between those two outcomes, and it is measurable in re-prompt hours and re-onboarding days. A concrete test: ask whether a layer like Knownbase or OzBrain can hand back tagged, provenance-linked notes another MCP-compatible agent can read without the original vendor present. Terms risk compounds this. Roughly 60% of 175 AI tools changed monetization-relevant terms in 15 weeks, so a memory vendor's export policy can shift after your client retainer is signed. Price portability before capability.
