TLDR: Choose Signado if you want people from relevant LinkedIn posts and comments, with their role, company, words, and a clear reason to contact them in one place. Choose Trigify if you need more networks than LinkedIn. Choose PhantomBuster or Clay if you want to build the process yourself. Choose Sales Navigator if you mainly search by job title and company.
The best tool depends on what you want it to do. Choose Signado for a ready list of people from LinkedIn conversations. Choose Trigify for more social platforms. Choose PhantomBuster or Clay if you want to connect the parts yourself. Use Sales Navigator when profile and company filters matter most.
This ranking is deliberately narrow. It asks one question: which option helps an agency, consultant, or B2B service business turn a useful LinkedIn post or comment into a person worth contacting? It does not rank tools by contact database size, number of automations, or sending volume.
If you want the complete manual process before comparing software, read how to find people discussing the problem you solve on LinkedIn. For the wider tool category, use the LinkedIn prospecting tools guide.

Decide what a LinkedIn social listening tool should monitor
Social listening on LinkedIn should do more than count brand mentions. For finding clients, it should show a useful post or comment, the person behind it, and the company where they work.
A general social media listening tool may show keywords, brand mentions, trends, and analytics in a dashboard. That is useful when you want to measure what people say about your brand. It may not tell you which person you can help or what that person actually said. To find warm leads, you need the conversation and a simple check of the person and company.
That is the test used in this list. Each option must help you find LinkedIn activity, see the original source, or turn a public discussion into a person worth checking. Tools that only publish content or report page statistics are not included.
Rank LinkedIn social listening tools on five criteria
The strongest tool for this list must keep the conversation. A profile URL alone is not enough. You should see what the person posted or commented, check whether you help people like them, and decide whether their words give you a real reason to reach out.
The ranking rewards four things: the original post or comment stays visible, weak matches are removed, setup is simple, and the price makes sense for a service business. A tool ranks lower when it gives you names but leaves you to build another system before you can judge them.
Signado comes first because it does this exact job with the least setup. It is not the best tool for every job. Trigify watches more social networks. PhantomBuster gives you more ways to automate. Sales Navigator has stronger LinkedIn profile filters. Clay gives you more control over research and company data.

1. Use Signado to qualify LinkedIn conversations
Signado watches public LinkedIn activity around keywords, relevant creators, competitors, and individual posts. A keyword source can find people writing matching posts or people engaging with them. Creator and competitor sources find commenters around audiences your buyers already follow. A single public post can also be checked once for commenters, reactors, or both.
The useful part is what stays beside each name. You see the original LinkedIn post or comment, the person's profile, their company, why Signado kept them, and how close their words are to asking for help. You can read the evidence before deciding whether this is a possible client, another provider, or someone you should ignore.
The free plan includes 200 lifetime credits. Starter costs $59 per month and includes 2,500 monthly credits. One complete new lead costs 5 credits. That includes the person, role, company, original post or comment, score, reason, and buyer stage. Finding an email is optional and costs 5 more credits when one is found.
You can write the message yourself for no extra Signado credits. You can also connect Signado to Claude Code or Codex and let your existing AI use the lead, post, and comment to help you write it. This uses no Signado message credits. Your Claude or Codex plan still applies. If you want Signado to write the message inside the product, it costs 7 credits.
Signado can send from connected Gmail or custom SMTP. It can also pass selected leads to Instantly, HeyReach, webhooks, Zapier, Make, n8n, or CSV.
Who it suits: agencies, consultants, and B2B service businesses that want a ready list of warm LinkedIn leads without connecting several tools first.
Where it falls short: Signado finds engagement leads on LinkedIn, not Reddit, X, YouTube, or podcasts. It does not replace your CRM. It is not built for large automated email campaigns. Choose another option if you need several social networks or want to build every step yourself.
2. Choose Trigify to listen across more platforms
Trigify describes itself as the "Signal Layer for AI Agents." Its public site says it resolves person-level activity across 11 or more social platforms, including LinkedIn, X, Reddit, YouTube, podcasts, and professional networks. It also exposes that activity through an API, MCP, and CLI.
That breadth is Trigify's clearest strength. Choose it when possible clients discuss the same problem across several public channels and you want to send those results to AI agents or other tools. It is a better choice than Signado when LinkedIn alone is not enough.
Trigify's current pricing page lists Starter at $40 per month for 4,000 credits and 25 searches. Max costs $199 per month for 40,000 credits and unlimited searches. Both show a 14-day trial. Enterprise pricing is custom, and extra credits are listed at $0.012 each.
The tradeoff is setup. Trigify is built for AI agents that use data from many sources. If you only want LinkedIn posts, comments, a person and company check, and one list to review, test whether the extra options help or add work. Its Starter plan is cheaper than Signado's. Choose based on the job you need done, not on which tool claims to be better overall.
3. Build custom LinkedIn monitoring with PhantomBuster
PhantomBuster offers more than 100 automations and workflows. Its public examples include finding people who engaged with a LinkedIn post, collecting profile details, enriching records, and exporting the result to another system.
Choose PhantomBuster when you already know the exact operation you need. You might collect people from one post, enrich their profiles, remove duplicates, and export a CSV on a schedule. That control is useful when the source rules vary by client or campaign.
The public annual-billing prices are $56 per month for Start, $128 for Grow, and $352 for Scale. Start includes 20 hours of execution and five slots. Grow includes 80 hours and 15 slots. A free trial is available.
Its weakness comes from that flexibility. PhantomBuster now lists intent signals, AI filtering and writing, lead warming, added contact data, and LinkedIn automations. You still choose the sources, connect the automations, set the rules, check the results, and manage runs connected to your LinkedIn account. Pick it when you want that control. Pick a simpler tool when you want less setup.
4. Use Sales Navigator to repeat native searches
LinkedIn Sales Navigator is the strongest choice here for native profile and company filtering. Core costs $119.99 per month or $1,079.88 per year. Advanced costs $159.99 per month or $1,799.88 per year. Advanced Plus has custom pricing.
The useful pairing is Sales Navigator plus saved searches. LinkedIn's help page says users can save keyword and filter criteria, receive weekly email and home-page alerts for new matching people or companies, and keep up to 50 lead searches and 50 account searches.
This fits a well-defined market. If you know the roles, company sizes, industries, locations, and account traits that matter, saved searches create a repeatable way to spot new matches. LinkedIn's Lead Pages guide shows how recent activity can then support manual research.
The limit is where it starts. A saved search finds people who match your filters. It does not take one discussion about your buyer's problem and give you the participants with their comments attached. Use Sales Navigator when finding the right roles and companies is the hard part. Add manual research or an engagement tool when knowing what people said is the hard part.
5. Build your own system with Clay
Clay is for people who want to build the full system themselves. It combines data providers, company research, custom scores, added contact data, and automations. Its current pricing page includes social listening signals on the Launch plan.
The Free plan lists 100 data credits and 500 actions each month. Launch is currently $185 on monthly billing or $167 per month when billed annually. That plan includes the social listening signals needed for this use case.
Clay suits you when deciding whether someone is a good lead requires your own checks. An agency could start with LinkedIn activity, add website and company data, ask a research question, find contact details, calculate a score, and send the result to another tool. Clay can connect those steps, but the LinkedIn activity may need to come from another source such as Trigify. Clay gives you more freedom than a ready-made list.
That freedom creates more work. Someone must build the table, choose providers, watch credit use, handle missing data, and keep the rules current. Choose Clay when you want that control. Skip it when you just want to add a source and review people.
6. Start with manual LinkedIn listening for full control
The manual option is better than buying the wrong product. Search LinkedIn posts for phrases your buyers use. Open useful threads. Read the comments. Check each person's profile and company. Put the person, source URL, exact comment, reason they match, and contact status in a spreadsheet. This is a simple way to test a market.
The software subscription is $0. The method also gives you direct exposure to buyer language, weak keywords, irrelevant creator audiences, and the difference between a lively thread and a useful one. That learning is valuable before automation.
Manual work becomes difficult when you repeat it often. You must rerun the same searches, check new comments, spot duplicate people, and keep the original posts. Different people may also judge a lead differently unless the rules are written down.
Use the manual route to prove one source and one simple rule. Add software when it produces people worth contacting but the repeated checking takes time away from client work.
Choose the option that fits what you want to own
Choose based on the work you do not want to do. Signado gives you a ready list from LinkedIn conversations. Trigify watches more social platforms. PhantomBuster collects data with automations you choose. Sales Navigator gives you LinkedIn's own search filters. Clay lets you build your own research system. Manual work costs no software fee but takes the most time.
Run a small test first. Pick one topic, one creator, one competitor, or one post. Review the people it produces. Do not ask only, "How many leads did it find?" Ask, "How many of these people would I contact after reading what they wrote?"
That test shows the real difference between tools. A large export can still leave you with nothing useful to say. A smaller list with the original posts and comments can be much more useful.
Start with the conversation
Signado finds the people already talking about the problem you solve on LinkedIn.
The best tool is the one that helps you decide who to contact and why. If you want LinkedIn leads with the original post or comment and a reason beside each name, Start Free. If you need more social networks or want to build every step yourself, choose the tool made for that job.
These tools all assume you know who to contact
Signado fills that gap: it finds the people already talking about what you do on LinkedIn, with what they said attached. Use it alone or feed the rest of your stack.
