Humanlinker vs Neuron (2026)
The decision is whether you want the vendor to have made something about the person, or to have kept nothing. Humanlinker's distinguishing product is an inference. It reads a named individual's public professional activity and produces a four factor behavioural profile, then tells the seller what to do and what to avoid with that type, on every tier including the trial. Its own homepage sells the resulting asymmetry, promising the buyer will understand their prospects better than those prospects understand themselves. The subject is never told the profile exists, cannot see it, cannot correct it, and inference means there is nothing to correct it against. Neuron builds nothing to keep. Work addresses are assembled as permutations at the moment of the request and tested against the recipient's own mail infrastructure before they are handed over, and the user agreement states plainly that prospect information is provided at the moment of use and is not stored by the vendor. One vendor's asset is a record it invented about someone. The other's is a record that stops existing when the request completes.
- The consumption economics have to be legible before the seat price is agreed. The entry tier is sixty nine euros per user per month with the annual total shown excluding tax, a monthly against annual toggle carrying a stated twenty percent discount, a slider for one to five users and a choice of three currencies. Allowances are stated per tier, and the credit unit is defined by action rather than by lookup: one credit produces one full outbound sequence, three produce one prepared meeting, and the vendor states plainly that navigation and data access consume nothing.
- The sending discipline should ship whole rather than in the top tier. Warm up runs on both the mail and the social side, mailbox rotation spreads sending across two to four connected accounts, volume and sending limits are exposed as customer configuration rather than fixed by the vendor, a domain suppression list blocks named organisations, unsubscribe links are included from the trial upward, out of office replies reschedule the contact rather than burning a touch, and prospects who have left their employer are identified so sending to a dead address stops.
- Customer evidence has to name the people in it. Roughly twenty testimonials each carry a full name, a job title and an employer, most with a specific figure attached, and the customer wall carries recognisable European names including a major cloud provider, a national news title and an agency inside a global advertising group. Independent recognition is checkable rather than self awarded, spanning a national business magazine feature, national television coverage and selection as a winner of a major software company's generative programme.
- There should be no credit arithmetic to model. Paid tiers are unlimited on email addresses, mobile numbers and exports, so there are no credits to price, no reveals of different sizes drawing on one pool and no rollover question to answer. The paid entry point carries a number and a unit at seventy nine dollars per user per month with a monthly and yearly toggle, three tiers carry a full feature comparison across all of them, and payment methods and tax treatment are both stated.
- The security page has to enumerate rather than assert. A service organisation control report is named with its type, which is the distinction that separates an operating effectiveness period from a design assessment, and it sits beside a control set laid out across application, infrastructure and operations, with encryption in transit and at rest stated, least privilege stated for integration permissions, a published vulnerability reporting route rather than a one, and a commitment to complete customer security questionnaires during the sales cycle. Infrastructure is named to a primary region in Oregon across multiple availability zones.
- The asset should accumulate in your systems rather than the vendor's. Data from the buyer's stack is treated as transient and the user agreement states that prospect information is provided at the moment of use and is not stored, so there is no proprietary store to extract from and no credit balance to strand at the end. Exports are unlimited and unmetered on every paid tier, four connectors cover the system of record, a spreadsheet destination and both of the sequencers a buyer at this size already licenses, and single sign on ships through two providers on every tier including the free one.

The short version of each
Humanlinker
Humanlinker is a French sales copilot combining prospect intelligence with multichannel outbound, whose distinguishing capability is behavioural profiling: it infers a four factor personality type for a named individual from their public professional activity and tells the seller how to frame a pitch for that type, on every tier including the trial. The GTM Tech Index grades it C on recipient disclosure and authenticity and records the row as the strongest candidate yet for tightening that band, because the subject is never told the profile exists, cannot see it, cannot correct it, and inference leaves nothing to correct it against, while the vendor's own homepage sells that asymmetry as the benefit. Alongside it, generating and sequencing comments on a prospect's posts is a shipped campaign step on every tier.

Neuron
Neuron supplies business contact data through a browser extension rather than a fixed database, from a Waterloo company trading as Planleaf, with every paid tier unlimited so the credit arithmetic governing most of this category is absent. The GTM Tech Index grades it B on data licensing and provenance, because it answers mechanically the question most of the category dodges: work addresses are assembled as permutations and verified in real time against mail exchange and mail transfer infrastructure rather than served from a stored file, mobile numbers are attributed to named supplier categories covering mapping providers, public listings, corporate websites and telecom providers with a second confirmation step, and the vendor draws an explicit scope line by supplying corporate contact data and declining personal contact data.

Common questions
Is Humanlinker better than Neuron?
They sit at opposite ends of what a data product can be, and that is the decision rather than a feature gap. Humanlinker generates a four factor behavioural profile of a named individual from their public professional activity and keeps it, and the GTM Tech Index records that as the strongest candidate yet for tightening its recipient disclosure band. Neuron assembles work addresses as permutations at the moment of the request, tests them against mail infrastructure and hands them over, and its user agreement states that prospect information is not stored by the vendor at all.
What is a behavioural profile and can the person see it?
It is an inference rather than a record, and no, the person cannot. Humanlinker reads a named individual's public professional activity and produces a four factor personality type, then returns guidance on how to frame a pitch for that type including what to do and what to avoid, on every tier including the trial and available on any profile through the browser extension. The subject is never told the profile exists, cannot see it and cannot correct it, and because the profile is inferred rather than collected there is nothing to correct it against. Neuron produces no equivalent asset.
How much do Humanlinker and Neuron cost?
Both publish a number, and the GTM Tech Index grades Humanlinker A on commercial transparency against B for Neuron. Humanlinker starts at sixty nine euros per user per month in three currencies, states allowances per tier and defines the credit by action, one for a full outbound sequence and three for a prepared meeting, with top up packs priced openly. Neuron starts at seventy nine dollars per user per month and removes the arithmetic instead, making paid tiers unlimited on emails, mobile numbers and exports. It is held below the top band because the ladder stops at a quote only top tier that holds the administrative equipment a growing team needs.
Which one tells you where the data is stored?
Only Neuron, which the index grades B on deployment and residency against C for Humanlinker. Neuron names one cloud provider with a primary location in Oregon in the United States across multiple availability zones, with the qualification that other regions are tapped as needed. Humanlinker publishes no region, data centre, cloud provider or residency commitment and offers no residency option at any tier. The company is French and says so prominently, which a European buyer may read as a residency signal, but corporate domicile is not a hosting commitment and the two should not be conflated.
Both are graded C on recipient disclosure. Why?
They arrive at the same grade from opposite directions, which is the clearest illustration of what separates them. Humanlinker sits at C because it creates something about a person that the person cannot see, and because generating and sequencing comments on a prospect's posts is a shipped campaign step on every tier. Neuron sits at C because it retrieves rather than creates, and its one genuine route is passive: the privacy policy commits to honouring instructions from a third party who writes in, which requires that the person already knows they are in the data and finds the policy. Address permutation also means a prospect's mail server is contacted by verification machinery before any human writes to them.
How does the GTM Tech Index grade Humanlinker and Neuron?
Both are graded on the same seventeen capability and compliance axes from public sources, and both carry a documentation depth of seventeen. The GTM Tech Index grades Humanlinker A on commercial transparency, and B on AI centrality, AI disclosure and model transparency, deliverability discipline, ecosystem depth, operational evidence and segment coverage, with no D on any axis. Neuron takes B on data licensing and provenance, deliverability discipline, deployment and residency, security certifications, commercial transparency, ecosystem depth and exit and portability, with no A and no D. The index publishes no composite score and declares no winner.

The shared silence is what each vendor learns from its own customers, and both raise the question themselves before leaving it open. Neuron states that the system learns the buyer's ideal customer profile by analysing their prospecting activity and then serves curated leads and dynamically scored profiles from it, and separately that verification improves through active learning, and whether either form of learning stays inside the account it came from is unaddressed, while its user agreement takes a perpetual, worldwide, sublicensable and transferable licence over anything a user submits, for any purpose, carving out only personal information.
Humanlinker offers dedicated models, model selection and fine tuning at its enterprise tier and states nothing equivalent for the tiers every other customer buys, so no published position covers whether connected mailbox content, professional network conversations, synchronised records or generated output train any model or cross between tenants.
The second observation is a mirror of the first and is the one worth taking to counsel, because each vendor publishes a compliance posture that stops short of its own core output. Humanlinker is established in the jurisdiction that wrote the European regulation, displays a compliance badge in its own footer, and publishes no notification route, access mechanism or objection path for a person whose behavioural profile it generated from material that person never handed it.
Neuron presents alignment with the European regulation and compliance with the Californian statute across three marketing surfaces, while its own privacy policy reproduces the Canadian carve out excluding an employee's name, job title and business contact details from personal information, which is the entire output of the product, and neither of those two regimes recognises that carve out.
The benign reading holds on both sides and is probably the correct one: these are marketing surfaces rather than legal filings, the governing documents sit elsewhere, and nothing here asserts that either company is out of compliance with anything. The buyer is still the one making the approach.
