      Appointment Setting Review from Troy Porter

      Our experience with Munzai was very positive. Zain was exceptional to work with. His communication was excellent, and anytime I had a question, concern, or request, he was quick to respond and willing to jump in and help. Adil also worked extremely hard on our account. He was persistent, consistent, and clearly put a tremendous amount of effort into trying to create opportunities for us. Ultimately, we did not get the level of results we had hoped for from the campaign. I believe part of that was because our service can be a difficult one to explain through outbound prospecting. Many potential customers are not already aware that a service like ours exists, so there is a significant amount of education involved before someone understands the value. What I can say confidently is that Munzai worked hard to try to make the relationship successful. They listened to our concerns, made adjustments, stayed engaged, and genuinely tried to help us succeed. I appreciated the effort, responsiveness, and integrity they demonstrated throughout the process.

      Outbound Review from Davey Warren 🍐

      Munzai Solutions has been a great partner for our outbound outreach. What stood out most was their communication. They checked in with us daily and weekly, kept us updated every step of the way, and worked closely with us to identify our target clients and the best directions to pursue. That level of consistent communication made the whole engagement feel efficient and collaborative, and it is a big reason we felt we got the best bang for our buck. We enjoyed working with them and would recommend them to other companies looking for a communicative, responsive outbound partner.

      Customer Support Review from Maria Maidana

      Helpware has been a trusted partner for SquadLocker for several years now for customer success. Our Customer Onboarding Team continues to shine through every administrator that interacts via our Live Chat channel for store help. Anzhelika is my Onboarding Lead and we work hand in hand in making any and all decisions for team enhancements. She delights both DIY and Enterprise administrators across multiple channels here at SquadLocker. I would not be as successful without Anzhelika by my side. I forsee using Helpware for years to come!

      My organization contracted with Helpware for a complete website design and build. I am extremely happy with the finished product and continually receive positive feedback from customers, vendors, and employees. The Helpware team was very professional throughout the entire process and did an incredible job keeping the project on time and on budget. Communication was also great and I really appreciated their consultative approach. I would recommend without hesitation.

      Swivel completely restructured our HubSpot instance and connected it to our ad platforms so we can finally see what's working. The team is responsive, strategic, and genuinely cares about our numbers, not just deliverables. Simcha and the team think like operators, not just marketers.

      I love the Swivel team! They make sure my calendar is fully booked with quality meetings. That’s where the rubber meets the road. Swivel’s 'Growth System' has been the perfect blend of marketing strategy and sales enablement. With their partnership, our sales team knows exactly which leads to prioritize, and has the processes & tech in place to maximize every buyer interaction.

      Swivel helped us with go-to-market, digital footprint, and templates/processes for our team to take forward! As a team of social service professionals with little marketing knowledge, we learned so much from them! They took our online presence to the next level with a user-friendly design that perfectly captures the essence of our mission. A new multi-channel campaign with content marketing levels us up and allows us to enhance our visibility to the schools that need our services the most. We highly recommended connecting with Swivel to make your marketing pop!
