Count the Real Cost of Building Agent Memory Yourself — and Why Most Teams Stop

The first sprint to "ship agent memory" looks cheap. By month six it owns half your engineering roadmap. MemoryLake replaces the months of plumbing — schema design, retrieval, dedupe, conflict resolution, versioning, audit — with one SDK and a free starting tier.

The problem: agent memory infra costs more than it looks

Schema design takes a week. Retrieval and ranking takes a month. Dedupe and conflict resolution takes a quarter. Versioning, audit, and compliance another quarter. Now multiply by your fully-loaded engineer cost. Most teams discover the "cheap" DIY route costs $200K+ in the first year.
