About Callbox
Callbox is a Los Angeles-listed B2B lead generation and appointment setting company running cold email, calling, LinkedIn outreach and account-based marketing across North America, Asia-Pacific, Europe and Latin America. Its site shows a logistics and supply chain case study and says it also works with manufacturing, and Clutch shows a large, mostly enterprise and midmarket client base.
Callbox is a B2B lead generation and appointment setting company. Clutch gives its headquarters as Los Angeles and its founding year as 2004, with further locations in Singapore, Ultimo in Australia, Medellin in Colombia and London. Clutch puts the team at 1,000 to 9,999 people. The site does not name a founder and lists no street address.
The offer is multichannel outbound. Callbox covers lead generation and appointment setting, account-based marketing, SDR outsourcing, demand generation, webinars and event follow-up, and stresses cross-border campaigns with outreach in languages including Thai, Bahasa, Vietnamese, Mandarin, Filipino, Portuguese and Spanish. Pricing is not published; the site says cost depends on market, account coverage, channels and language needs. Clutch summarises engagements as $12,000 to $80,000 a year, with a most common project size of $10,000 to $49,000.
For logistics, the site features a case study for a US logistics and supply chain leader, reporting 146 sales appointments over 12 months, which is Callbox’s own figure. Its FAQ says it also works with healthcare, manufacturing, logistics and workplace solutions, and Clutch shows manufacturing as a minor share of its work. Staffing is not mentioned. Other site case studies cover a managed-services provider and an office solutions business, and named client interviews include Kreller Group, Westernacher Consulting, B2X Global and Body Vision Medical.
It holds 4.6 across 128 Clutch reviews and the Premier Verified badge. Reviewers praise communication, timeliness and multichannel outreach, while criticisms include weaker performance in non-English markets, reporting that could be more detailed, and inconsistent lead quality in a few reviews. A March 2026 Clutch review from a national waste and recycling company describes appointments set through calling, email and LinkedIn. Callbox suits mid-market and enterprise B2B sellers, particularly logistics providers, that want one vendor across several regions. Small companies wanting a boutique, email-only programme will likely find better matches.
