Clevenio vs Leadibly (2026)
The decision is whether you need a named person or a working address. Clevenio builds from each country's official national business register and then uses large language models to cross reference those registers against public data across the web, attaching named decision makers to the right companies, with Finnish phone numbers drawn from telecom operator data and matched to the individual. What a buyer gets is a person, their role and a direct line. Leadibly does not attempt that. It queries a named mapping platform's official programmatic interface for business listings by sector and country, then crawls each resulting business website and extracts the contact address published there, so what a buyer gets is whatever that business chose to put on its own site, which is often a shared inbox rather than a person. The prices follow the difference. Leadibly charges about half a euro per delivered lead with a verified address, flat across all three tiers, and publishes the figures. Clevenio's pricing page reads ask for pricing under a heading that calls itself transparent.
- You want the sourcing disclosed in classes rather than asserted. The company layer comes from each country's official register with registration numbers, financial statements, industry codes, headcount and group structure, the person layer is disclosed as model matched from public data and professional networks, and the Finnish phone layer is disclosed as telecom operator data.
- You want the whole market rather than a list. The proposition is a mapped market rather than a sample, refreshed continuously so a newly registered company reaches your system of record without anyone noticing it, with connectors into three named systems of record.
- Agent access should not be an upgrade. A protocol server is live for every customer, included in both plans rather than sold as an extra and carried as the first banner on the homepage, naming two assistant clients so a buyer can query their own mapped market from inside an AI tool.
- The bill has to be computable from the page. Three tiers carry real euro figures on both billing periods, the unit is defined as leads delivered with a verified email address, allowances are stated per tier, sending is included with no separate charge, and a free trial delivers three verified leads with no card.
- The pacing should be published as a number. Sending is capped at one message per minute and appears as one of four headline statistics, messages are held to local business hours and time zones in each target country, a global blocklist screens invalid addresses, and each account carries its own barring list.
- You want the exit answered with a number. The full lead list exports to a spreadsheet at any time on every tier including the cheapest, and the privacy policy states data is deleted within thirty days of account closure, with monthly billing and no commitment period to escape.

The short version of each
Clevenio
Clevenio, trading as Sales Led Oy of Jyvaskyla, sells the whole market rather than a sample, building from each country's official business register and using large language models to cross reference those registers against public data across the web to attach decision makers to companies, refreshed continuously. The GTM Tech Index grades it B on data licensing and provenance, the most authoritative sourcing record in the index on that dimension alone: the company layer is government sourced and independently checkable, the person layer is disclosed separately and honestly as model matched from public data and professional networks, and the Finnish product adds a genuinely unusual disclosed route in telecom operator data matched to the named person.

Leadibly
Leadibly is a European business lead sourcing and cold outreach platform for agencies, consultants, freelancers and small sales teams, operated by FCO SRL of Italy, which searches business listings by sector and country through a named mapping platform's programmatic interface, crawls each business website to extract contact addresses, and sends drip campaigns through the customer's own mail server. The GTM Tech Index grades it A on commercial transparency: three tiers carry real euro figures on both billing periods with the stated annual saving checking against the arithmetic, the unit is defined as leads delivered with a verified email address, sending is included at every tier, and a free trial delivers three verified leads with no card.

Common questions
Is Clevenio better than Leadibly?
Whether you need a named person or a working address. Clevenio attaches named decision makers to companies using large language models over official register data, with Finnish phone numbers from telecom operator data matched to the individual, so a buyer gets a person, a role and a direct line. Leadibly queries a mapping platform's official interface for business listings and crawls each website for the address published there, so a buyer gets whatever that business chose to put on its own site, which is often a shared inbox rather than a person.
How much do Clevenio and Leadibly cost?
Leadibly, decisively, and the GTM Tech Index grades it A against D. Leadibly publishes three tiers with real euro figures on both billing periods, defines the unit as leads delivered with a verified email address, states allowances per tier, includes sending at no separate charge and offers a free trial of three verified leads with no card. Clevenio's pricing page carries the words transparent pricing above its headline and the words ask for pricing where the number belongs on both plans, with no tier, unit, floor, range or currency anywhere on it.
Where do the addresses actually come from?
Both name their sources, which is unusual, and they name different kinds. Clevenio publishes three classes: official national business registers for the company layer, large language model matching against public web data and professional networks for the decision makers, and telecom operator data for Finnish phone numbers. Leadibly names the mapping platform's official programmatic interface for discovery in its privacy policy and describes enrichment plainly as visiting each business website and extracting the address published there, with no resold static database anywhere.
Which one protects deliverability?
Leadibly publishes considerably more of it. Sending is capped at one message per minute as a headline figure framed as pacing that protects the sender, messages are held to local business hours and time zones in each target country, a global blocklist screens invalid addresses before they are attempted, unsubscribes are honoured automatically, and sends, errors and bounces report in real time. Clevenio runs multichannel sequences and publishes nothing on warmup, authentication, inbox placement, bounce or complaint thresholds or volume governance, arguing the point indirectly through data quality instead.
Where is the data processed?
Leadibly publishes the more precise residency claim and Clevenio publishes none. Leadibly names the hosting provider, the country and the specific data centre region code in the footer of every page alongside a plain statement that application data sits in the European Union, though two named suppliers sit outside that claim and neither is reconciled with it. At Clevenio no hosting provider, region, residency option or sub processor list was located on the vendor's own surface, with a third party review platform reporting European processing rather than the vendor stating it.
How does the GTM Tech Index grade Clevenio and Leadibly?
Both are graded on the same seventeen capability and compliance axes from public sources, and both sit at sixteen axes graded above the floor. The GTM Tech Index grades Clevenio B on AI centrality, AI disclosure and model transparency, data licensing and provenance, platform terms exposure, ecosystem depth and segment coverage, with a D on commercial transparency. Leadibly takes A on commercial transparency and B on deployment model and data residency, exit and data portability, deliverability discipline and segment coverage, with a D on operational and outcome evidence. The index publishes no composite score and declares no winner.

Both vendors assemble contact details for people who never interacted with them, and both resolve the lawful basis question by moving it rather than answering it. Leadibly's privacy policy states that the customer acts as an independent controller for the leads they collect and contact and is responsible for ensuring their outreach complies, which is a complete transfer of the obligation to the buyer, and it sits directly beneath a homepage advertising full compliance as one of its four headline statistics.
The same policy explains the basis for holding those contact details by saying the information is publicly available business information, which describes a source rather than a ground. Two further pieces of the supply chain are named and unaccounted for: discovery runs through a named mapping platform's official programmatic interface with no licensing position covering the reuse and redistribution of listing data obtained that way, which is exactly what a downloadable contact list represents, and the second mechanism, crawling each business website to extract the address published there, carries no stated method, no robots directive handling and no rate discipline.
Clevenio's version of the same gap is quieter and lands on individuals rather than businesses. It holds direct phone numbers and email addresses for named decision makers across at least ten countries, assembled by model inference and, in Finland, from telecom operator data matched to the person, and no notification, self service lookup or removal route was located anywhere on the site.
The European provision governing data obtained from sources other than the individual applies squarely to that, and this is a Finnish company operating inside the jurisdiction that wrote it. Ask both what the basis is, and ask each what a person in the corpus can do about it.
