      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.

      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.

      We've been working with Reexia for our sales outreach and lead generation, and they’ve been absolutely outstanding. Their service is incredibly personal and responsive — it genuinely feels like they’re part of our team.

If you’re looking for a hands-on, strategic partner to drive your sales pipeline, we can’t recommend them enough.

      LM Companion is a really helpful (free!) resource for staying up to date on the many legal events, award deadlines and networking groups. Being able to add events and deadlines directly to my calendar saves a lot of time. I would certainly recommend to other busy legal professionals looking for opportunities to raise their profile, or gain a broader understanding of all the PR and marketing opportunities out there.

      LM Companion is great for legal PAs, BD assistants and anyone who wants to be proactive in finding marketing and BD opportunities for their team. Instead of manually searching for conferences, awards etc for my fee earners, LM Companion means I'm only searching through opportunities relevant to my practice area, which is a huge time saver. I've also found out about events and awards that I hadn't come across before - would highly recommend!

      Holly has been a great help recently both in terms of my business and personal affairs. I am in the process of making some business structure changes in my private dental practice and she has assisted me with all the lengthy paperwork, ensuring that everything is in order. In addition, she has assisted me in researching properties and locations. I would not hesitate in recommending her services as her support has been invaluable to me at this extremely busy time and has allowed me to focus on my patients. Highly recommended +++++

      Terri has been an incredible SmartPA assistant for our family over the past 18 months. Her support has been invaluable in managing our busy work and home administrative tasks. Throughout our travels across Europe, the US, and Canada, as well as during our recent move to a new house and country, Terri has been there for us every step of the way. In particular, I have appreciated that Terri has used great judgment in assessing options on all fronts and hasn't just gone for the easy road of blindly following orders. I have trusted her as a "second me" and that has been so helpful. We couldn't have done any of this without her!
