      Lead Generation Review from Eileen Byrne

      Partnering with MKC Agency has been a game-changer for our business. Guided by Megan's inspiring journey and resilience, her team transformed our brand, spearheaded a go-to-market strategy, and even implemented a CRM system that streamlined our operations. Within just three months, we secured two new deals and established a promising sales pipeline, a testament to their expertise. What truly sets MKC Agency apart is their values-driven approach. Their commitment to ethical marketing and societal change is unparalleled. Their core values reflect a deep understanding of both professional and personal growth. My only wish? That I had discovered Megan and her team earlier. Highly recommend MKC Agency for any business aiming for genuine growth and connection

      Finance & Operations's Review Sourced from Google

      We strongly advise against engaging with this company, especially for outsourcing services. My experience with them has been nothing short of disappointing and frustrating due to several key issues: 1. Unprofessional Service and Communication: From the start, the company demonstrated a complete lack of professionalism. Their responses to client inquiries were not only delayed but often dismissive. Instead of addressing concerns and providing solutions, they seemed uninterested in maintaining a positive client relationship. Communication with them feels more like a burden rather than the collaborative process it should be. 2. Inconsistent Client Communication: There is no consistency in the way they communicate with their clients. At times, they respond promptly, but more often than not, communication is sporadic and incomplete. It’s as if they have no structured process in place for managing client interactions, which leads to unnecessary confusion and delays in project timelines. 3. Untrustworthy PartnersOne of the most concerning issues is the reliability of the company and its partners. Throughout the course of our collaboration, they failed to honor agreements, missed deadlines, and provided substandard work. It became increasingly clear that they lack transparency and integrity in their dealings. Trust, which is critical in any business relationship, was eroded quickly. The leadership of this company, particularly the Head of Business Development, is highly unprofessional. The way they handle client relationships is a clear reflection of the poor management and lack of oversight within the organization. Their attitude is not only dismissive but at times, outright rude and condescending. There is no effort to engage clients in meaningful discussions or to offer solutions when problems arise. For anyone considering outsourcing with this company, We highly recommend avoiding them at all costs. They have no clear processes in place, and their inability to deal with clients in a respectful and professional manner speaks volumes about how poorly run this organization is.

      Worst company that you can deal with 1. Unprofessional service and communication with clients 2. Inconsistency in communicating with clients 3. Untrustworthy partners Highly recommend to avoid this company for outsourcing company especially their the business development head. The way they respond to their clients gives a clear indication how badly this company is led. Basically there is no clear process, extremely rude way of dealing with clients. Just take a look a the email response and the response in the comments and you will know how unprofessional this company is.

      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!

      One of the best 💯 I would say I will always choose to be with this friendly, fantastic and very accommodating company. I always had a chance to to be hired with other bigger companies but I'd rather choose BIGOUTSOURCE no matter what. It's actually my second home. I feel safe and happy when I'm with BIGOUTSOURCE. I love everything about it. ❤️❤️ No doubt this company is one of the growing company in the Philippines. ❤️
