The buyer is on a site. A reply is worth more here than anywhere else.
The argument
The buyer is on a site, not at a desk, so the ordinary engagement signals mean something different: an email opened three times is not research, it is somebody reading on a phone between jobs. Replies carry the largest share of any pack because getting an answer at all is the hard part and a fast one is genuinely informative. Marketing signals are worth little, since this buyer does not read a nurture sequence. Meetings matter because a demo usually happens in person or not at all. Process weight covers the one real gate, which is whether the tool survives contact with crews who did not ask for it, and adoption worry is the objection that kills these deals late.
The weights
74% of the score comes from what the company does, 26% from what named people do. Within each side, these are the shares.
The demo loads with these weights. Move them and watch the deals reorder.
