Should we build a company brain in-house or buy Heidi?
Build if company memory is your product. Buy if it is your infrastructure. The system is deceptively deep, ingestion, permissions, consolidation, forgetting, trust, receipts, and it never stops needing work.
The in-house version starts as a two-week RAG prototype and becomes a permanent platform team: connectors break, permissions drift, memory rots without curation, and audit requirements arrive with the first serious customer.
Heidi is that platform team, amortized across every customer, for $300 a month plus token cost. Your engineers integrate over the API in an afternoon and go back to your product.
