Where to find customers who are Amazon FBA sellers

Amazon FBA sellers are not 'marketplace sellers' in the abstract and they are not dropshippers who never send a carton to a fulfillment center. They live inside Seller Central: IPI scores, restock limits, inbound placement service fees, aged-inventory surcharges, stranded listings, A-to-Z claims, hijackers on parent ASINs, and reimbursement tickets that take 90 days. If you sell repricers, PPC software, listing optimization, 3PL overflow, FBA prep, accounting that understands FBA fees, or a restitution scanner, these operators are already posting the job in r/FulfillmentByAmazon, Seller Central forums, Helium 10 and Jungle Scout reviews, and YouTube 'I closed my FBA brand' videos. Do not hunt 'Amazon entrepreneurs'. Hunt the person who just screenshotted a storage-fee invoice, a suppressed listing for a missing warning, or a Buy Box they lost to a hijacker with a $0.01 undercut. That person has inventory in a building they do not control and a reason to switch tools before the next inbound appointment.

Where Amazon FBA sellers actually hang out

These are the rooms where Amazon FBA sellers ask for recommendations, compare tools, and name the competitor they want to leave. Start here before you buy ads.

Redditlarge, operator-heavy
r/FulfillmentByAmazon
This is the unfiltered FBA ops channel: IPI crashes after Q4, 'Amazon lost 40 units and reimbursed at cost not retail', restock limits blocking a restock of the hero SKU, and weekly fights about whether Helium 10's Cerebro is still worth it versus Jungle Scout. Sellers paste inbound shipment error codes and FBA fee preview screenshots. Those codes are the product spec. Sort by new when Amazon emails a fee change; search your incumbent plus 'storage' or 'reimbursement'.
Rules gotcha: The subreddit is allergic to 'I'll review your listing for free' funnels. Help with the actual inbound or IPI problem. Disclose if you make PPC or repricer software. Do not recruit for a wholesale course.
Forumofficial, high intent
Amazon Seller Central forums
Sellers go here when they think Amazon will unblock a gated category, explain an inbound discrepancy, or restore Buy Box after a hijacker. Threads about FBA new-selection, inventory-performance, and 'account health dashboard is wrong' are gold because the ASIN is in production pain. Amazon staff sometimes reply, which means your comment has to be more specific than a blog. Category-gated brands (supplements, batteries, kids) cluster here in ways Reddit does not.
Rules gotcha: Amazon's forums punish solicitation. Do not harvest Seller IDs. Partner-looking posts get reported. Answer the policy, then mention a tool only if they ask how you file reimbursements.
Reviewsdecision-stage
Helium 10, Jungle Scout, and Keepa reviews
FBA sellers leave G2 and Trustpilot reviews when a suite billed them after they paused PPC or when Cerebro keyword data diverged from Search Query Performance. Two-star reviews on Helium 10, Jungle Scout, SmartScout, and Sellerboard describe the exact broken job: 'refund estimate is wrong', 'PPC rules bid me into a loss', 'can't see FBM vs FBA split'. That paragraph is your comparison set. Read reviews dated after Amazon's last fee or Search Query Performance UI change.
Rules gotcha: Do not astroturf G2. Vendor replies on your own listing are fine. Do not DM reviewers who dinged a competitor. Take the cons text to Reddit and Seller Forums where they asked a question.
YouTubehigh leverage comments
FBA PPC and fee breakdown channels
Creators film Seller Central walkthroughs of storage surcharges, ACoS vs TACoS, and 'should I send this inbound'. Comments are where mid-size brands admit they cannot get a restock limit raised or that a 3PL overflow still cannot match FBA Prime conversion. Follow a handful of FBA operators (not get-rich courses) and read every upload's comments for 48 hours after a fee email from Amazon.
Rules gotcha: Course affiliates will delete comments that threaten the $997 masterclass. Be useful to the commenter's SKU economics. Never paste a coupon as the first reply under a 'I made $50k' thumbnail.
Facebookhuge, mixed quality
Amazon FBA seller Facebook groups
Facebook still holds a lot of private-label and wholesale FBA sellers who learned from YouTube ads and never joined Reddit. Useful posts are operational: 'prep center lost my cartons', 'how do you fight a false IP complaint', 'Sellerboard vs Helium 10 profits'. Filter out RA flipping flex and 'I'll find you a product for $200' noise. Spanish and German groups are where EU FBA Pan-EU headaches actually get discussed.
Rules gotcha: Most groups require admin approval and ban software vendors who lead with a Loom. Answer two reimbursement or inbound questions as a human. Some require a vendor flair and a no-link period.
LinkedInbrands and agencies
Amazon seller and brand-operator LinkedIn
Once a catalog clears roughly seven figures, the person buying software is often a director of Amazon or a brand manager, not the founder in a Facebook group. They post about agency ACoS, DSP vs PPC, and whether to pull inventory back to a 3PL for multi-channel. LinkedIn is weaker for panic tickets and stronger for stack replacements at a real ACV. Watch comments on fee-change posts from well-known Amazon consultants.
Rules gotcha: Do not InMail a cold sequence that says 'I help Amazon sellers 10x'. Comment with a specific IPI or reimbursement tactic. Procurement-minded buyers will ask for security and SOC2 before a login.
Xreal-time incidents
Amazon sellers on X
When Amazon loses inbound, suppresses a listing, or emails a new aged-inventory surcharge, operators tweet before they open a case. Reimbursement Twitter is its own genre. That window is when a precise reply ('check the fulfillment-network stock transfer, not the shipment') earns a follow. Also watch screenshots of Keepa graphs after a hijacker appears.
Rules gotcha: Do not dunk on an Amazon outage to sell a scanner. Offer the diagnostic. Pitch later if they ask which reimbursement tool you run.

What Amazon FBA sellers complain about — and what that means

PainHuntr classifies conversations by intent: actively asking, comparing, frustrated, discussing, or a passing mention. The quotes below are the shape of demand, not a promise that a specific post is live today.

Frustrated
“Amazon lost a pallet, reimbursed at COGS, and the case has been 'under review' for 11 weeks. Sellerboard's estimate and the actual payment do not match and support just says wait.”
r/FulfillmentByAmazon reimbursement threads, Seller Central lost-inbound posts, and 1-star reviews of profit dashboards.
Comparing
“Helium 10 vs Jungle Scout vs SmartScout for a 40-ASIN private label. I need Search Query Performance mapped to actual spend, not another keyword toy I forget to open.”
G2 comparison threads, YouTube 'I tried Amazon tools' comments, and Facebook FBA groups after a price hike.
Actively asking
“Looking for a prep center that can actually label FNSKU, bag, and meet inbound appointment windows for a hazmat-adjacent SKU without a two-week queue.”
Seller Central logistics threads, Facebook FBA groups, and Reddit inbound error-code posts.
Discussing
“Restock limits on the hero SKU are lower than Q4 velocity. We are debating overflow 3PL plus Multi-Channel Fulfillment versus eating the lost Buy Box.”
LinkedIn Amazon-operator posts and Reddit after capacity emails.

How to reach Amazon FBA sellers without getting ignored

FBA sellers are interrupted by tool upsells inside Seller Central and by course ads on every YouTube video. Diagnose the screenshot: IPI, shipment ID, ASIN suppression reason, ACoS on a given match type. If you cannot tell FBA from FBM from SFP from the post, ask one logistics question, not a discovery call. Disclose that you make software as soon as you recommend a workflow you sell. Never promise 'we get your reimbursements automatically' without saying which transaction types you actually parse. Q4 is for keeping inbound moving, not for a six-week POC; the sellers you help in October remember you when they re-tool in January. Facebook groups will ban a first-comment Loom. Seller Forums will report solicitation. YouTube comments should help them read the fee preview in the video. The allowed pitch is a specific case-log note and a public changelog of which Amazon report you support.

Frequently asked questions

Are Amazon FBA sellers the same as online marketplace sellers?

No. Multi-channel sellers on eBay, Walmart, Faire, and Mercari care about listing syndication and repricers across storefronts. FBA sellers care about inventory sitting in Amazon's network: IPI, inbound fees, reimbursements, and Prime conversion. If your product is a 3PL WMS or a Walmart connector, use the marketplace sellers page. If it reads Seller Central reports, stay here.

How do I avoid getting banned while promoting FBA software?

Do not lead with a URL or a free listing audit that is actually a funnel. Answer the inbound, IPI, or PPC question, disclose that you built a tool if you recommend it, and skip threads that are really wholesale courses in disguise. Seller Central forums and r/FulfillmentByAmazon have seen every growth hack. Specific case advice is the only loophole that still works.

Where should I watch for competitor frustration?

G2 and Trustpilot 1–3 star reviews on Helium 10, Jungle Scout, and Sellerboard; Reddit threads that name those suites; and YouTube comments on fee and PPC roundups. Amazon fee-change weeks and Search Query Performance UI changes create clusters of 'this number is wrong' posts.

Do wholesale, private label, and retail arbitrage hang out together?

Yes, which is why the noise is high. Filter for FNSKU, restock limits, and contribution margin after FBA fees if you sell to brands. RA threads talk about store runs and clearance. Private label talks about inserts, A+ content, and hijackers. Your ACV and your pitch should not mix those three.

What should an FBA tool founder paste into PainHuntr?

Your product URL and the two suites you replace (often Helium 10, Jungle Scout, or a reimbursement scanner). PainHuntr looks for sellers asking for that job, comparing dashboards, and raging about a fee preview that did not match — not everyone who said Amazon once. Add the queries on this page for Seller Forums and Facebook if you still hunt by hand.
