Why We Changed the Name
DeciGraph was technically correct. It described what the product does: a graph of decisions. But "technically correct" is not the same as "memorable." In conversations with early users, we kept hearing the same feedback: "What does DeciGraph do again?" The name was generic, hard to Google, and did not communicate the product's core insight — that AI agents need something analogous to a biological memory system.
Hipp0 communicates function through metaphor. The hippocampus is the brain structure responsible for consolidating short-term memory into long-term memory. It is the biological "decision memory layer." The name Hipp0 (with a zero, not the letter O) is distinctive, memorable, and immediately suggests what the product does to anyone with even passing familiarity with neuroscience. Plus, we got the hipp0.ai domain.
The 202-File Commit
Renaming a project that has already shipped is not trivial. The rebrand touched 202 files across the
monorepo: environment variables (DECIGRAPH_ became HIPP0_), package names,
database references, documentation, the marketing site, CI/CD pipelines, and every import path. We wrote
a migration script that handled 90% of the changes automatically, then spent two days on manual review
for edge cases — string interpolation in templates, third-party config files, and community-facing
documentation that needed careful wording updates.
The Hippocampus Analogy Runs Deep
The rebrand was not just cosmetic. It sharpened our product thinking. Once we committed to the hippocampus metaphor, features started naming themselves: "Agent Wings" (like neural pathways), the "Evolution Engine" (memory consolidation), "Collab Rooms" (shared memory spaces). The name became a design language that guided both engineering and product decisions. Sometimes a rename is just marketing. This one changed how we think about the product.
