      Lead Generation Review from Patrick Benasillo

      Belkins nailed project management. Each stage of the outbound funnel was thoroughly calculated, allowing us to use data-driven insights to make informed decisions and making sure both sides implemented strategies effectively. Communication was clear and proactive, and they maintained full transparency throughout the process. In the first month, we closed our first contract, which was a promising start. Belkins helped us build a robust sales pipeline. Currently, we have four opportunities at the proposal stage, averaging $85K, with the potential for these contracts to grow up to $150K. We didn't expect to close deals and contracts so quickly. Belkins exceeded our expectations by not only creating a solid base for future work but also securing contracts right off the bat. Their ability to deliver quick and substantial results was very impressive.

      Appointment Setting Review from Rafael

      Belkins played a crucial role in refining our customer profile and identifying key features of our ideal buyer. It meticulously researched relevant leads to construct a targeted contact list. Our partnership with Belkins commenced in May 2023, and by February 2024, it secured 51 appointments for us. With an impressive 43% open rate and a 3.7% reply rate, we exclusively focused on the United States market and the architecture industry. Thanks to Belkins' efforts, we expanded into the Canadian market and explored opportunities in other industry sectors. Hiring Belkins as our lead generation specialist ensured a consistent influx of new clients. We were impressed with the agency's efficient strategies.

      Lead Generation Review from Allison Hill

      Belkins helped us define our ideal customer and find the right leads. They created targeted email sequences that highlighted our value in different ways. We started our collaboration 6 months ago and Belkins set 36 appointments for us. We saw a 57% open rate and a 5-6% reply rate. We focused on the U.S. market but now we're starting to expand to Canada and some European countries.

  • Revolutionizing Remote work.

    We believe that every BPO company knows and understands what they do. But very few know why they do what they do. And by "why" it does not mean to "make a profit" because that's a result and it always will be.With the Remote Group, our ultimate goal is to build relationships with those who share our beliefs  [... view The Remote Group profile ]

      As a client, we were impressed by the well organised process. From the recruitment process to on boarding of our team, we were constantly been kept informed of the progress. Though its our first time outsourcing in the Philippines, we know we've made the right decision. There's no language barrier with our all-Filipino team, they speak in fluent English with neutral accent! Thank you TRG.
