Moat
Drop-in compression improves token efficiency and accuracy; becomes embedded in agent/RAG workflows.
Key risk
LLM providers (OpenAI, Anthropic) may build compression natively; low switching costs.
Why now
LLM token costs rising; RAG and agent adoption growing; context compression optimization needed.
Competitors
Emerging space, potential LLM provider integrations
