By being their remote marketing arm, we help companies across industries like IT and Software, Manufacturing, Management Consulting, Healthcare, Finance, and Advertising find the best quality leads and sales appointments with the greatest chance of becoming profitable customers.

Backed by quality data, skilled people and a robust marketing tech stack, we set your company up for success with account-based marketing, lead generation, appointment setting and sales enablement tools that work together to power your customer acquisition by providing a steady stream of leads to your sales teams, be they office-based or working offsite.


What Callbox offers its clients

Our main lines of service include: lead generation (identifying decision makers that match your target buyers), appointment setting (booking sales meetings with qualified prospects), webinar marketing (promote, facilitate, and nurture) and data-related solutions (collecting and compiling actionable intelligence on your target buyers). Callbox uses a multi-touch, multi-channel strategy when reaching out to your target customers. This means we connect with your decision-makers through live, one-on-one conversations enhanced through email, social media, search, and direct marketing channels throughout different points.

How Callbox outshines the competition

We do our lead generation unlike any other. We don't just randomly call a list or blast an email and hope for responses, we follow an account based marketing approach. This means we contact multiple decision makers in a company and reach out with messaging that's tailored to each contact's position. We created a technology that allows us to execute a truly integrated multi channel lead nurturing process.

Our automated Lead Nurturing tool allows us to set triggers when to phone a client. Moreover, we obtain information on your target prospects primarily from our in-house database of 35 million target accounts/companies. Callbox also supplements its internal prospect database with data from reputable third-party providers as well as information collected through custom research. In addition, we also give you the option to submit your own prospect list to be used in the campaign.

We offer robust and flexible pricing for scaling your business.
Whether you’re just getting started with lead generation or looking to boost your customer acquisition, Callbox has the services, people, and resources to help you scale your growth while keeping the costs low. Learn more:

Callbox company structure

Callbox started life as a Los Angeles, CA-based startup in 2004.

In 2005, we branched out into outbound call center services, and things pretty much picked up from then on. We pioneered many of the tactics that would become standard practice in multi-channel strategies.

This allowed us to rapidly expand our operations and grow our customer base, and the company soon established offices in Singapore, Malaysia, and the United Kingdom. Today, Callbox is home to more than 700 employees and has carried out over 10,000 campaigns.
