Lumis provides AI synthesis from your own reading list, every morning. The difference is between reading someone else's analysis and getting a briefing synthesized from the sources you've chosen.
The core question: do you want periodic analyst reports on private markets, or a daily briefing synthesized from your own research sources?

Sacra is the right choice if you want **pre-researched institutional reports** on private markets and tech sectors. If you prefer to read finished analyst analysis rather than synthesize from primary sources — Sacra's structured reports deliver that at a subscription tier suited for professional investors.
It's also the better fit if you want **periodic deep-dive analysis** rather than daily monitoring. Sacra publishes research reports on specific themes and companies; Lumis delivers a daily briefing every morning. Different information cadences serve different needs.
And if you value **structured analyst research** with methodology and evidence — Sacra's reports are written to institutional standards.
Lumis is built for professionals who track **multiple sources** and need a daily briefing synthesized from all of them. Sacra gives you their analysts' reports on private markets. Lumis gives you an AI agent that synthesizes the RSS feeds, newsletters, and research streams you personally choose to follow — every morning.
The core difference: pre-researched reports vs. your specific sources. Sacra covers what their analysts decide to research. Lumis covers what happened overnight in the sources you've chosen to follow.
For operators, investors, and analysts who track multiple sectors or technology domains, Lumis delivers broader coverage from your sources than any single research publication can provide — at a fraction of the cost.
