A comparison
Different jobs.
Don't mix them up.
Sales Navigator and the signal tools are built to find people you don't know yet. Jellydoor is the morning list for people you already mean to stay close to.
LinkedIn Sales Navigator
LinkedIn's own help describes Sales Navigator as a way to find leads, save accounts, get alerts, and message people with InMail. Core is a single seat. Advanced is for a team, and LinkedIn says it adds shared lists and buyer intent signals.
LinkedIn's compare page, which that page says was updated on 27 September 2026, lists Core from £94.99 a month and Advanced from £130 a month. The same page says those figures are estimates, can change, and may exclude tax.
Jellydoor does not search LinkedIn for new buyers, does not send InMail, and does not sync a CRM. It starts from the people a team has already named. £120 a seat a month, five seats minimum. First month up front, then month to month with no lock-in.

Signal tools
Signalist's site describes turning LinkedIn likes, comments, followers and profile visitors into people you can contact, along with other signals such as open jobs, funding and events. It says some of those signals need a confirmed LinkedIn account. It also says a message can be a draft you review, or something you write yourself.
Dealmayker's site describes itself as account intelligence. It says it watches accounts for funding, hiring, job changes, tech shifts and posts, and tells you who to contact, when, and what to say.
Jellydoor does not look for new companies from hiring or funding. Each morning it tells a seat, from the list the team already keeps, who is due a hello and whether that person has posted something worth a reply. If not, it says skip today. You send the reply yourself. It works inside Claude for now, it never logs in, and it can't post.
