B2B Review from Greg Digneo
Best decision we made last year was partnering with this CX team for our customer support, billing, and sales assistance. We were drowning in client emails and chasing invoices late at night instead of focusing on SEO strategy. Results have been incredible: client response times dropped from hours to under an hour, payment collection improved 60%, landing page conversions up 28%, and client retention increased 35%. They integrated seamlessly with our systems and scaled with us as we grew. Now we have more time to focus on delivering SEO results instead of being stuck in support tickets all day. If you're an agency juggling client support with campaign management, this team is a game-changer.
BPO Review from Nimmit Shah
Collaborating with Hugo elevated our property management firm's performance. Their support solutions slashed response times by 40% and boosted tenant satisfaction by 30%.

Lead Generation Review from Joachim Fong
For the past year, Callbox has provided us with satisfactory lead generating and lead nurturing services. They were instrumental in securing attendees for our events, scheduling client appointments and facilitating the sale of one of our benchtop systems. Their professionalism in conveying our product attributes and valued solutions to prospective customers has brought us results.
Lead Generation Review from Jonathan Anderson
I’ve used Callbox now for about four months for my internet marketing company. The first two months they did not pay off. However with some additional training on my part, they started to close a higher percentage of my target audience. They’re really smart, nice and are really working hard to keep my business. My dedicated team keeps me up-to-date through frequent communications. My R.O.I is getting stronger and my CPA is starting to drop.
Appointment Setting Review from Ted Calvin
Charted Energy has enjoyed a productive relationship with Callbox. They have done a great job of helping us target prospects within the markets we serve as well as qualify leads and set up appointments with decision-makers. Callbox has generally exceeded the number of leads per week we expected and provides a good value by enabling our inside sales team.
