INSTRUMENT / PRIVATE-MARKET TELEMETRY
Every company announces itself twice. The first time is a filing.
STEALTHINDEX reads the first announcement — Form D filings, incorporations, hiring exhaust — and surfaces companies while they are still in stealth.
By application
The press release is a courtesy — extended to everyone who wasn’t in the deal. The record existed months earlier. It was public. Nobody read it.
No press releases. No secondhand databases. The instrument ingests what the market never reads — and has, going back to 2008.
Nothing in this record began as news.
A Delaware incorporation. A founder quietly changing jobs. A Form D nobody covered. Each alone is a data point. Co-firing, they are a surfacing — scored for momentum, placed in its sector cluster, flagged where capital is thin.
Identity withheld. Members see the name.
A small number of firms hold seats. Occasionally, one opens.
