E-discovery LLMs.
AI-driven document review for litigation, privilege, relevance, summarization.
Reading the two labels: team-sized build build cost means only makes sense as a team bet, multiple quarters of salary before any revenue, the kind of project incumbents are better positioned to start. Hot, multiple deals per month deal velocity means multiple funded companies are landing in this category per quarter right now.

How to validate it in an afternoon
Before committing build time or a thesis memo to e-discovery llms, run three cheap checks against public engineering activity. Each takes minutes and none require access to private data.
- Count active builders. Search GitHub for repositories matching this category, then check how many accepted commits in the last 14 days. More than a handful of active teams means the category has energy, not just mentions.
- Look for the hot, multiple deals per month pattern in funding. If funded companies keep appearing here, multiple funded companies are landing in this category per quarter right now. Cross-check the legal tech leaderboard to see whether any of the accelerators sit adjacent to this niche.
- Test the team-sized build cost assumption honestly: only makes sense as a team bet, multiple quarters of salary before any revenue, the kind of project incumbents are better positioned to start. If your calendar cannot absorb that, the opportunity is real but not yours yet.
