      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.

      I worked here for 3 months and my experience was (contrary to the reviews below) very nice, easy going. The management accommodated my personal circumstances and provided ease into adapting to the role, support was always available as well as humour and banter from colleagues. Perfect transition job from hospitality to office roles. Bonus points for progressing employees internally to higher roles accordingly.

      An Ash's Review Sourced from Google

      How did managers help with a transfer of service for a customer who left review.Because at managements rule is to never disclose that they are calling from at management,they are only to represent and use their clients name. What’s even funnier is this customer was considered special from the rest. They were not only informed it was at management dealing with their service but they even knew the real names of the managers.Another common practice is staff and managers mostly use a dummy name not their real. But in this case even that info was provided to the customer. Must be a special customer that the normal practices were broken for them and they from millions of customers even took the time to write a review lol . Everyone laugh with me.

      Both Adnan & Connor at AT Management were superb in their dealings with me over the transfer of a service when I was moving house. Nothing was too much trouble & their knowledge was very good. I’d have no hesitation in recommending these two individuals or AT Management

      Lead Generation Review from James Nolan

      We worked with Reexia to support our outbound business development and lead generation efforts. The team helped us structure a targeted outreach campaign and build a relevant prospect database for our market.Communication throughout the project was clear and organised. We had bi-weekly calls to review activity and results, and Kevin was very hands-on in guiding the campaign and suggesting adjustments where needed.Results took some time to appear, but this was explained clearly at the start of the campaign and expectations were set appropriately. Once the campaign gained momentum, we began having conversations with companies that matched our target profile.Overall, it was a positive experience and we appreciated their structured approach to outbound prospecting.

      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.

      We have worked with the Excelerate360 team on several occasions - they stay ahead of the tech curve to deliver their services, always bring solid advice and pride themselves on being realistic rather than selling unachievable results. We value integrity and openness, and that is why we like working with them. They do a very tough job and they do it very well. A supplier that can be trusted.

      E360 offer a great set of services especially valuable for early stage businesses that don’t have the cash to hire a full time sales guy or team or don’t want to make that commitment. But regardless you are tapping into a team that can help you get your sales playbook nailed and generate early revenues. Gavin has been helping us build a pipeline in a new sector and it’s like working with your own team, fully integrated and committed. I honestly recommend these guys without hesitation.
