Callbox is a global lead generation company that helps businesses connect with high-value prospects and book qualified sales meetings.

We combine AI-powered tools and human expertise to deliver consistent results through multi-channel outreach—phone, email, LinkedIn, chat, and events.

With 20+ years of experience and over 10,000 campaigns, we’ve helped clients across software, SaaS, fintech, and other industries build stronger pipelines and close more deals.

Our AI lead generation services use intelligent tools that identify the right decision-makers, craft personalized messages, and score leads based on intent.

Our proprietary Smart Engage platform integrates AI for account-based targeting, automated sequencing, and analytics—while our trained specialists ensure human-to-human connection throughout the process. This Team + AI approach improves appointment rates by up to 30% and speeds up sales cycles by 25%.

Callbox has a global footprint and proven track record across North America, APAC, EMEA, and LATAM. 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.

Whether you’re expanding into new territories or scaling your presence regionally, our local expertise ensures seamless execution.

We start by identifying your Ideal Customer Profile (ICP) and target markets. Then, our team and AI systems build and validate a customized prospect list.

From there, we engage decision-makers through calls, emails, social media, and webinars until they qualify as sales-ready leads or confirmed appointments.

Our end-to-end appointment setting service ensures your sales team speaks only with prospects who match your exact criteria.

Our core model is subscription-based for flexibility and scalability, but we can design custom pricing that aligns with your campaign goals and lead volume.

While we don’t operate strictly on a pay-per-lead or commission basis, our focus is on ROI—delivering verified, qualified leads and meetings that translate into real business opportunities.

Pricing varies depending on your campaign scope, target market, and engagement model.
We customize every program to ensure the right balance of activity (calls, emails, LinkedIn touches) and lead quality.

Book a consultation with our sales team to get a tailored quote and see which lead generation service package best fits your goals.

You can do either. We have an in-house data research and enrichment team that builds and maintains verified B2B databases across industries.

If you already have a list, we can clean, validate, and enrich it. If not, we’ll create one from scratch that aligns with your ICP and region—ensuring accurate and compliant outreach under GDPR, CCPA, PDPA, and CAN-SPAM standards.

Our clients typically see a 30% increase in appointment rates and 25% faster sales funnel movement after working with Callbox.

Results depend on your industry, audience, and message alignment, but every campaign is monitored and optimized through our AI analytics and team feedback loops to ensure continuous improvement.

Yes. Callbox provides B2B lead generation and appointment setting services for industries such as Software, SaaS, Cloud, Cybersecurity, Fintech, AI, Healthcare, Finance, and Manufacturing.

We adapt our outreach strategy, messaging, and cadence for each vertical to ensure we reach the right decision-makers with the right value proposition.
