Personalization was never the problem. Repeating it was.
Anyone can write one brilliant cold email. Neurosigil makes the thousandth as grounded as the first: neural models read each prospect like an analyst, a symbolic core types every finding as a sourced claim and vetoes what it can't prove — so the process repeats without drift. Efficient, scalable, and above all practicable. Powered by Blackglass.

sales-led · no card required · 5 claims sealed →
Brilliant once, different every time. Ask a model twice, get two emails — and occasionally a fact nobody can find. Variance compounds at scale.
Repeatable, but blind. Rules and templates run the same forever — and read nothing. That's mail merge, and prospects can smell it.
The net dreams, the sigil pins it down. Neural reading, deterministic claims and rules: same inputs, same sealed outcome. Repeatability is what makes it practicable.
Every sentence, sealed to a source.

Hi Alex — congrats on shipping v4[3]. Saw your post about on-call scaling[5] — with a Go / K8s stack[4] at your size, most teams hit exactly that wall. We built something for VPs of Engineering[2] who want the pager quiet without hiring for it. Worth 15 minutes?
Two minds. One wire. Zero fiction.
Readers fan out
Neural models read the subject's public footprint like an analyst, not a scraper.
Findings become claims
Every extraction is a typed symbol with a source pointer and timestamp — or it doesn't exist.
Rules fire
Emails re-verified live at the MX, stale facts expire, unsourced claims are vetoed.
