The Five Reasons DIY Agent Memory Fails the Moment It Hits Production

The five recurring failure modes:

1. Concurrency — Two agent processes write at once and one silently loses.
2. Scale — Memory works at 10K users; breaks at 1M.
3. Audit — Customer asks "why did the AI do that?"; no traceable history.
4. Compliance — Enterprise buyer requires ISO 27001 / SOC 2; you don't have it.
5. Deletion — User invokes right-to-delete; backups still hold their data.

Each of these is a quarter of engineering work to fix. Doing them all in DIY is a year.

1. Connect — Drop the SDK in.
2. Structure — Production gaps closed by default.
3. Reuse — Ship with confidence the memory layer holds.

Engineering leaders deciding between continuing to invest in DIY agent memory or moving to a production-ready memory layer — where the five gaps above are pain points they recognize.
