Cleon1

Cheap verified mobiles with unlimited emails bundled

B2B Databases

Overview

Cleon1 is a small US vendor selling verified direct and mobile phone numbers, with unlimited B2B work-email lookups thrown in on paid plans. Phone credits are the only metered unit: emails are flat-rate under a 100k/mo fair-use cap, while a verified phone costs 1 credit. Entry is $39/mo for 25 phone credits and $79 for 100, with extra credits from $0.20. Its genuinely unusual feature is that credits stay valid for 2 months on monthly plans and 12 on annual, instead of resetting every cycle.

Who it's for

The honest take

Where it breaks

No independent review of this vendor exists anywhere: it is absent from G2, Capterra, GetApp, TrustRadius and Product Hunt simultaneously, and the only public rating is 2 anonymous Chrome Web Store stars. The scale behind it is tiny, at 89 extension users, one employee on LinkedIn, unfunded and founded in 2024. It also publishes no contact counts, no country coverage and no match rate while criticising rivals for poor phone accuracy. Practically, 100 phone credits on the top self-serve tier is thin for a working SDR, the API is Pro-only and its documented spec covers phone enrichment but not the email endpoint the homepage advertises.

The verdict

Cleon1 is an unproven budget option whose one real differentiator, rolling credits plus unmetered emails from $39, is genuinely attractive at very low phone volume. Everything else argues for caution: no third-party validation at all, a single-operator vendor, no published coverage data, and a ceiling of 100 mobiles a month before overage. Treat it as a cheap experiment on the free tier or a low-cost extra leg in a waterfall, benchmark its numbers against a provider you already trust, and do not put a revenue-critical workflow behind it.

FAQ

What does Cleon1 actually charge for?

Phone numbers. A verified mobile or direct dial costs 1 credit, while work-email lookups are unlimited on paid plans under a 100k a month fair-use policy. That makes it a phone vendor with emails bundled, not a general enrichment tool.

How many phone numbers do I get?

25 a month on the $39 Starter tier and 100 on the $79 Pro tier. Extra credits start at $0.20, so 500 numbers a month works out near $159 once overage is added. The published ladder stops there.

Do the credits expire?

Not immediately, which is the main draw. Phone credits stay valid for 2 months on monthly subscriptions and 12 months on annual ones. If you cancel, the balance resets to zero at the end of the billing period.

Which tools does it connect to?

Attio and Google Sheets natively, and that is the whole native list. Zapier, Make and Clay are reachable only as generic HTTP calls against the API, and there is no Salesforce, HubSpot or sequencer integration.

Is there an enterprise plan?

No. There are three tiers and nothing above Pro, with no SSO, no published DPA and no SOC 2. The site says GDPR and CCPA aligned rather than certified, which will stop most mid-market procurement.
