Who wrote this, and how. I run outbound for B2B clients, so I compete with the agencies on these pages. The facts come from each agency's own website, checked in September 2026. There are no star ratings or review counts, because I could not verify them first hand.
In short
Callbox, founded in 2004, runs phone led B2B lead generation with teams in several countries and campaigns localised per market. It prices per campaign pod and publishes estimated ranges.

| Channels | cold calling, cold email, LinkedIn, web retargeting, chat, webinars and events |

| How they describe themselves | "B2B Lead Gen powered by Human + AI." |

Published figures. These are quoted from callboxinc.com. Prices change, so check the source before you rely on them.
What they offer
Teams across the US, UK, Australia, Singapore, Malaysia, Hong Kong and Colombia, with campaigns localised for each market's language, from one vendor.
Worth asking before you sign
Most delivery runs from the Philippines. Ask which team will work your market and in which language, and ask them to confirm the monthly figure for your scope, since the two published ranges differ.
Markets and coverage
Own FAQ: 'We operate in multiple time zones with teams in the US, UK, Australia, Singapore, Malaysia, Hong Kong, and Colombia, delivering localized campaigns tailored to each market's language and business culture.' Site claims 60+ countries and coverage across North America, APAC, EMEA and LATAM, with GDPR-compliant EU outreach. Pricing FAQ notes price 'varies depending on ... supported languages'.
Who it suits
Mid-market and enterprise technology companies entering several regions at once that want phone led coverage from one vendor.
Who should look elsewhere
Single-market campaigns on a small budget, and markets where buyers do not take calls.
Other agencies buyers compare
Three things sort a shortlist faster than a feature list: whether the agency publishes a price, which channels it actually runs, and whether it covers your market.

How I work, for comparison
I'm a GTM consultant based in Riga. I run cold email and LinkedIn as one motion for B2B companies, and I do the targeting, the offer and the copy myself.
- Consulting and fractional GTM from EUR 2990 a month, published and month to month. Done-for-you outbound runs through my agency, Shipyard GTM.
- A flat monthly fee. Nothing is priced per meeting.
- You keep the domains, the lists and the playbook when we stop.
I'm a good fit if you sell B2B into Europe or the US and want one person accountable for the whole thing. I'm not the right fit if your deal size can't carry a four figure monthly fee, or if you need a large team on the phones. Pricing has the detail.
