Who wrote this, and how. I run outbound for B2B clients myself, so every agency on this page is a competitor of mine. Treat this as one operator's read rather than an independent rating. Everything factual here comes from the vendor's own website, quoted where it matters. I have deliberately published no review scores or star ratings, because I could not verify most of them first hand and a wrong number attached to someone's company is not worth the page.
In short
Leadium is the most publicly candid company in this comparison about its own history, including the parts most agencies would bury. That candour is the reason to take it seriously.
At a glance
| Headquarters | Las Vegas, Nevada, US |
|---|---|
| Founded | 2015 |
| Pricing | Not published |
| Channels | cold email, cold calling, LinkedIn, SMS, gifting |
| Delivery model | 100% US-based in-house SDRs, fully managed, deliberately boutique |
| How they describe themselves | "We're not a software. We're not a tool." |
How they charge
No commercial model is published on the site.
Where they are strong
An unusually honest public record. Their own timeline documents founding CIENCE in 2014, exiting it, launching Leadium in 2015, and then deliberately contracting from a much larger client portfolio to a far smaller one after selling the international operations. A vendor that publishes its own contraction is a vendor likely to tell you the truth in a sales call.
The trade-off
Small and deliberately smaller than it was, which means less redundancy if your account team changes. Nothing about pricing is public.
Markets and coverage
United States. Their About timeline records selling off international operations in 2022 'to double down on a boutique, fully U.S.-based team'. No non-English language coverage is claimed.
Who it fits
Mid-market and enterprise teams that value a small senior vendor and a straight conversation over scale.
When to look elsewhere
Teams that need a large vendor's bench, or published pricing for procurement.
Alternatives worth shortlisting
The useful comparison is rarely feature by feature. It is whether the vendor publishes a price, which channels they actually run, and whether they cover your market. Those three sort the list fast.
| Agency | Pricing | Channels | Best for |
|---|---|---|---|
| Belkins | Not published | cold email, LinkedIn, omnichannel outbound | US mid-market, omnichannel |
| CIENCE | Published | cold email, cold calling, LinkedIn | Itemised build plus flexible SDRs |
| Cleverly | Published | LinkedIn, cold email, cold calling | Cheapest entry, LinkedIn led |
| Callbox | Published | cold calling, cold email, LinkedIn | Multi-region, phone led |
| Martal Group | Not published | cold email, LinkedIn, cold calling | Senior onshore reps who close |
| SalesRoads | Not published | cold calling, cold email | US phone, cancel anytime |
| Hlib Storchak | Published | cold email, LinkedIn | Baltics to Nordics, one operator |

Where I fit, and when I do not
Founder led, from Vilnius. Cold email and LinkedIn as one motion, with the targeting and the offer fixed before anything sends. Published: consulting and fractional GTM from EUR 3,000 a month, done for you outbound from EUR 7,000 a month. Flat monthly fee, no per meeting pricing.
I am the right call when B2B teams selling into the Baltics, Nordics, wider Europe or the US who want one person accountable for the whole motion rather than a pod, and who want to keep the system afterwards.
I am the wrong call when If your deal size cannot support a four figure monthly retainer, if you need cold calling as the primary channel, or if you need a large vendor's bench, I am the wrong choice and I will say so on the call.

Is this review independent?
I run outbound for B2B clients myself, so every agency on this page is a competitor of mine. Treat this as one operator's read rather than an independent rating. Everything factual here comes from the vendor's own website, quoted where it matters. I have deliberately published no review scores or star ratings, because I could not verify most of them first hand and a wrong number attached to someone's company is not worth the page.
Why are there no star ratings on this page?
Because I could not verify most of them first hand. Review platforms block automated reading, and the figures circulating in other agencies' comparison articles disagree with each other. Publishing a number I cannot stand behind, attached to a named company, is not worth the page. What I can verify is what each vendor publishes about itself, so that is what this compares.
