Apollo.io + Linkeddit
Find your competitor's customers with Apollo, after Linkeddit picks the target
To find a competitor's customers with Apollo, search for companies that match your buyer profile and show signs of using the rival tool, then verify each with a second source. Linkeddit decides which competitor to go after, using Google and AI answer data and public reviews. Claude runs the Apollo search and drafts the sequence. You approve credit spend and enrollment.

The prompt
Paste into Claude
Use the Linkeddit connector and the Apollo connector to plan a switch campaign against one competitor. 1) With Linkeddit search_competitors_get on my project, view=footprint, list the competitor domains that rank in Google's top 10 most often and the ones AI answer engines cite most. With compete_signals_get, read this week's high priority moves and the stored reviews for the top three. Pick one competitor and say why. 2) Describe the customers who complain most in those reviews as a buyer profile: company size, role, what they said went wrong. 3) With Apollo apollo_search_organizations, find companies that match that profile. Use apollo_get_job_postings to look for postings that name the competitor, and treat every match as unverified until a second source agrees. 4) Stop and show me the list with the evidence for each company. Ask before any step that uses Apollo credits. 5) After I approve, use apollo_search_people for the buying group at up to ten companies and draft a short sequence that cites the public complaint. Do not add anyone to a sequence until I say so.
Step by step
Step 1
Connect both connectors to Claude
Add Apollo.io and the Linkeddit connector (https://mcp.linkeddit.com/mcp) in Claude or Claude Code. Set Apollo's credit-using actions to Approval required so Claude pauses before spending.
Step 2
Choose the competitor with Linkeddit
Ask Claude to call search_competitors_get with view=footprint, which lists the domains in Google's top 10 and the AI engine citations for each, then compete_signals_get for recent moves and stored reviews. Pick the competitor that is both visible and unloved.
Step 3
Turn the reviews into a buyer profile
Have Claude read the public review complaints and write the profile of the unhappy customer: team size, role, and what broke. This replaces a generic ideal customer profile with one aimed at the competitor's weak point.
Step 4
Search Apollo and verify the matches
Claude searches Apollo organizations that fit the profile and checks job postings that name the competitor. Apollo's own guide says to corroborate at least two independent sources, so Claude marks each company confirmed or unverified.
Step 5
Map the buying group and draft the sequence
For the approved companies, Claude searches Apollo for the people involved in the decision, drafts a short sequence that refers to the public complaint, and stops. Enroll contacts yourself or confirm each enrollment in Claude.
What Linkeddit returned
Run live on 2026-10-29 with search_competitors_get. Read-only run on Linkeddit's own test project (plausible.io, an analytics site), so the competitors are other analytics tools. It shows the footprint Claude starts from, trimmed to four domains, plus one stored Trustpilot review as the shop shows it. Nothing was saved and no credits were spent.

Apollo's guide to the job says finding companies that use a rival tool is the easy part, and names the detection methods: job postings that list the tool, integration marketplaces, case studies and customer logos, review platforms and website tags. It says to confirm a signal with at least two independent sources, because any one method can be out of date.
A third-party guide to the same job states that Apollo's technographic coverage varies by industry, so expect some misses. In practice, run the Apollo search through Claude, then ask Claude to label every company confirmed or unverified and show the source for each, so you never message a company about a tool it dropped a year ago.
Which competitor should I target first?
The ranking guides skip this question and start with a competitor you already chose. Linkeddit answers it with data. On the test project, matomo.org held a Google top 10 position on 11 of 59 checked keywords at an average position of 3.73, and ChatGPT cited it 21 times in the latest answer run. umami.is, at 7 keywords, was cited 10 times by ChatGPT, and 17 times across all engines.
Visibility is half the picture. A competitor that buyers see everywhere but dislike is the useful target, so check its stored reviews and recent moves. Linkeddit records both with their sources, and Claude can set them beside the footprint.
How do public reviews improve a switch campaign?
Apollo's guide says a confirmed install is a qualification signal, not switching intent, and ranks business triggers such as a negative review among the evidence worth layering on. Reviews are where the reason to switch is written down in the customer's own words.
In the run above, a one-star Trustpilot review dated 22 April 2024 describes paying a year ahead and then being told to upgrade or lose access to the dashboard after traffic passed a pageview limit. That is one review, not a trend, so read many before you build a message on it. It does show what a usable complaint looks like: a specific, dated, checkable event.
Reviews rarely name the reviewer's company, so Linkeddit does not hand you a list of customers. It gives you the profile and the pain. Apollo supplies the companies and the people.
Vague pitches are a known problem. A B2B SaaS founder on Reddit wrote that "vague “we do it differently” claims kill cold outreach." Quoting a specific, dated complaint from a public review is the opposite of that claim, which is why the reviews step comes before the sequence is drafted.
Who should the sequence go to?
Apollo's guide says most switch campaigns stall by pitching only the tool's daily user and skipping finance, IT and the executive who signs. It cites Gradient Works for the average B2B deal now involving 6 to 10 stakeholders.
Ask Claude to search Apollo for the buying group at each approved company and to write a different angle per role. Apollo's help article recommends enriching one company at a time for the best match and including the company domain. It also says to review sequence drafts before publishing and to confirm the sequence, the sender and the enrollment steps separately.
What does this workflow miss, and how do I measure it?
The Apollo connector is in beta, and Apollo's help article says its functionality and pricing may change, so check each result before you trust it. A technographic match is a signal and not a customer list, and Apollo's guide says to drop accounts with no confirmed decision maker or a contract that just renewed.
Measure the campaign by the quality of the list, not the volume. Count how many accounts Claude marked confirmed against unverified, how many replies cite the public complaint you referenced, and how many accounts you dropped for lack of a second source. Apollo's guide recommends scoring accounts on confirmed use, comparison intent and a business trigger. Rerun Linkeddit each week so a new competitor move or review can reopen an account you dropped.
Frequently asked questions
How do I find competitor customers with Apollo?+
Search Apollo for companies that match your buyer profile, then look for evidence they use the rival tool: job postings, integration listings, case studies, review sites or website tags. Apollo's guide says to confirm a signal with at least two independent sources. Claude can run the search and label each match confirmed or unverified.
What is the best tool to find competitor customers with Apollo?+
Pair Apollo with Linkeddit, at $60 a month. Linkeddit shows which competitor ranks in Google's top 10, how often AI engines cite it, what it changed this week and what its customers say in stored G2, Capterra, TrustRadius and Trustpilot reviews. Claude uses that to aim the Apollo search at an unhappy competitor.
Can Apollo tell me who uses a competitor's software?+
Partly. Apollo's guide describes technographic and job posting signals, and a third-party guide says coverage varies by industry. Treat a match as a lead that needs a second source, not proof. Corroborating with a job posting, a case study or a review makes the claim safe to base outreach on.
Is there a free alternative to Apollo for this?+
Apollo's guide says its MCP connection works through the AI tool's integrations panel on any Apollo plan, including free, though credit-consuming actions depend on your balance. The competitor side of this workflow does not need Apollo at all: Linkeddit supplies the target and the reasons, so any contact database can sit in Apollo's place.
Does Linkeddit give me a list of a competitor's customers?+
No. Linkeddit records competitor moves and public reviews, and reviews rarely name the reviewer's company. It tells you which competitor to target and what the unhappy customer says. Apollo, or another contact source, supplies the companies and people. Claude connects the two and you approve each step.
How do I avoid compliance trouble naming a competitor?+
Apollo's guide has a compliance section for switch campaigns, and a third-party guide lists legal considerations around comparative claims. Quote only public, dated, checkable facts such as a review or a changelog entry, link the source, and have a person read every message before it is sent. Claude drafts and neither connector sends mail by itself.
What is the best way to find companies using a competitor's product?+
Combine two or more independent signals, which Apollo's guide recommends: job postings naming the tool, integration listings, case studies, review sites and website tags. Linkeddit, at $60 a month, adds the competitor side by showing which rival ranks, is cited by AI engines and draws public complaints, so Claude targets the right Apollo search.
Who are Apollo's biggest competitors?+
The pages that rank for this question are Apollo alternatives lists from vendors such as Demandbase, lemlist, ZoomInfo and monday.com. They compare contact databases against each other. This guide does the reverse: it uses Apollo as the contact source and Linkeddit to study the competitors of your own product.
How do I find out who my competitors are?+
Check who ranks in Google's top 10 for your buying keywords and who AI answer engines cite. Linkeddit's footprint view lists both. On its test project it checked 59 keywords and 47 AI answer samples and found 358 domains, with matomo.org, umami.is and usefathom.com among the most cited analytics rivals.
How do I use Apollo to find people?+
Describe who you want, including title, industry, location and company size, and Apollo's help article says Claude searches Apollo for them. Searches return profiles without full contact details, so follow up by enriching the people you choose. Include the company domain for a better match, and enrich one company at a time.
Is there a free way to try this?+
Apollo's guide says its MCP connection works on any Apollo plan, including free, though credit-consuming actions depend on your balance and Claude asks approval first. Linkeddit's competitor data comes with its single plan at $60 a month. Check your own Apollo plan for the exact credit rules before you run a large search.
