To build a targeted LinkedIn prospect list, define a precise ideal-customer profile, filter for it in LinkedIn or Sales Navigator, and capture each match into a sheet or CRM. A Simular AI computer agent can do this for you inside the real LinkedIn interface, with no extension and no API.
A longer prospect list is not a better one. Most people equate a good LinkedIn prospect list with a big export: 2,000 names in a spreadsheet, ready to email. The trouble is that the list starts decaying the day you save it, and much of it was never a fit to begin with. B2B contact data goes stale at about 22.5% per year, so precision and freshness beat raw volume every time.
Quick answer: to build a targeted LinkedIn prospect list, define a tight ideal-customer profile, filter for it in LinkedIn or Sales Navigator, then capture each match into a spreadsheet or CRM. LinkedIn has no native export and shows only about 1,000 results per search, so the real work is segmenting well and keeping the list fresh. A Simular AI computer agent can build and refresh the list for you inside the real LinkedIn interface, with no extension and no scraper.
| By hand | Simular AI agent | Extensions & scrapers | |
|---|---|---|---|
| Setup | None | Show it once, about 15 minutes | Install extension, connect your session |
| Speed / volume | ~2 min per profile | Human-paced, unattended, works the 1,000 and 2,500 caps by segment | Fast bulk, front-loads the risk |
| Cost | Free, your time | Subscription | $30 to $100+/month |
| Account risk | Lowest, fully compliant | Low: no extension, human pace | Highest: fingerprinted, ~48h restrictions |
| Targeting | Full, you judge each fit | Full, per your ICP rules | Bulk criteria, often loose |
| Best for | Small, high-value lists | Steady, refreshed lists at scale | One-off bulk dump, risk accepted |
Volume works against you: At about 2 minutes a profile, a 2,000-name export is over 66 hours of copying, and at 2.1% monthly decay roughly 42 of those names go stale before you finish the first send. Derived estimate.
The task generalizes across audiences. A VP of Sales mapping RevOps buyers, a tier 1 VC tracking seed-stage founders, a recruiter sourcing software engineers, and a marketer building a list of newsletter authors all run the same three filters. Only the criteria and the cadence change.
Run the search yourself and record each match. Zero ban risk, capped by your own typing speed.
Pros: lowest risk, full control over fit, no cost.
Cons: at roughly 2 minutes per profile, a 500-name list is over 16 hours of copy-paste, and there are no emails attached. By hand is the right call only for small, high-value lists.
Instead of installing anything, you show a Simular agent your build routine once, and it repeats it at a human rhythm and refreshes it on a schedule.
Simular runs an ordinary browser on a cloud virtual machine and works LinkedIn's own screens. So there is no add-on sitting in your Chrome for LinkedIn's extension scanner to catch, and no third-party API that can be throttled or revoked. You set the limits and approve the steps, and the agent pauses on anything sensitive. It is built by the team at Simular; see the Simular Pro page for how it runs unattended. Once the list exists, the same agent can find contact emails or export the search results for you.
Pros: targeted volume with no extension footprint, refreshed on a schedule, unattended.
Cons: a subscription, plus about 15 minutes up front to teach it your routine, and it is deliberately paced rather than an instant dump.
Tools such as Apollo, Evaboot, PhantomBuster, Waalaxy, and Dux-Soup scrape profile fields from your logged-in session and append emails. Quick, but they expose the footprint LinkedIn flags.
Pros: fast, bulk lists, with email enrichment bundled in.
Cons: LinkedIn scans for thousands of known extensions and can restrict accounts within about 48 hours. You are still capped at 1,000 and 2,500 per search, and the enriched emails still bounce as the data decays.
Two forces work against a big export. First, detection: an extension injects code into the page, which changes the DOM and the request timing in ways a normal session never shows. Session and headless scrapers leave their own tells, like the navigator.webdriver flag and canvas fingerprints. That inhuman signature is the real trigger, not the word "automation". Second, decay: people change jobs and abandon inboxes, so at about 2.1% per month a list is meaningfully wrong within a couple of quarters.
Pro tactics that keep a list targeted and fresh:
The mistakes that waste a list are consistent: a filter so broad it captures the wrong people, chasing volume over fit, and trusting a scrape you never refresh. Practitioners on Indie Hackers describe the same loop on repeat: install an extension, pull about 100 leads, and get restricted within 48 hours. The line worth pinning up: a prospect list is not an asset you build once, it is one you keep alive.
The winning pattern: define a tight ICP, segment past the result caps, and let a Simular Pro agent build and refresh the list on its own VM so your pipeline stays current while you focus on the outreach. When you are ready to enrich it, pair this with a profile-data extraction pass.
Start with a tight ideal-customer profile, then filter for it in LinkedIn or Sales Navigator and capture each match into a spreadsheet or CRM.
Because LinkedIn has no native export, you either copy rows by hand or hand the job to a Simular Pro agent that captures them for you.
About 1,000 on a standard account and roughly 2,500 in Sales Navigator, even when the search claims far more.
LinkedIn only serves 100 pages of results, so a broad search hides everyone past that ceiling, and the Sales Navigator 'Connections of' filter caps lower at 1,000 leads. Split a wide audience into narrower filtered searches to reach the rest.
Building a list by hand is compliant and safe; the risk comes from scraper extensions, which LinkedIn fingerprints and restricts, often within 48 hours.
LinkedIn's User Agreement bans bots and prohibited software and extensions, and it scans for thousands of known ones. A Simular agent avoids that net because it works LinkedIn's real screens at a human pace instead of injecting an extension.
Build one focused search per segment rather than one giant list, since a VP of Sales, a tier 1 VC, and a newsletter author each need different filters and signals.
Because B2B contact data decays about 22.5% per year as people change jobs and abandon inboxes, so a list built once is wrong within months.
That is why refresh cadence matters more than list size. A Simular agent can re-run the same search monthly and update titles and employers, keeping the list live instead of letting it rot.
