Callbox Inc

Callbox is a B2B lead generation and appointment setting agency that connects sales teams with qualified buyers. The company says it has spent more than 20 years doing this work, and it serves software, SaaS, cloud, cybersecurity, fintech and AI companies that want a steadier pipeline without building a large in-house outbound team. For businesses looking at outsourcing their prospecting, Callbox offers a fully managed alternative. The core service is appointment setting. Callbox assigns a dedicated team of appointment setters to each campaign, with no shared resources and no call center rotations. The process starts with defining an ideal customer profile, then building a target account list on Pipeline, the company's own AI prospecting platform. Callbox says this typically produces 2,000 to 8,000 matched accounts within 7 days of kickoff. From there, the team maps stakeholders at each account, from economic buyers to end-user champions, and writes messaging for each role. Outreach runs as a coordinated 9-touch sequence over 30 days, spanning phone, personalized email and LinkedIn. Phone is always part of the mix. Before a meeting lands on a client's calendar, it is screened against agreed criteria covering budget, authority, need and timeline, and confirmation sequences are sent to cut down on no-shows. Callbox reports an average no-show rate under 12%. Each booked appointment comes with a briefing note that includes conversation history, pain points and stakeholder context, and campaign data syncs to the client's CRM in real time. Weekly pipeline reports and bi-weekly strategy reviews are included. The company reports serving more than 15,000 companies across 60+ countries, running over 10,000 campaigns, and a 77% qualification rate on appointments. Its model pairs human sales development reps with AI tooling, which makes it a fit for teams looking for an AI-ready BPO partner on the sales side rather than a traditional call center USA vendor for support queues. Callbox is based in Encino, California.
