      Customer Support Review from Bogdan Czako

      We've been working with SupportYourApp to handle technical support, including product-related questions, password resets, tracing user traffic, and assessing request severity. The team started with two shared consultants and one dedicated consultant and now operates with two members, providing consistent support via email. Their performance has been outstanding, earning perfect 10/10 ratings in our internal performance reviews, and the project has remained extremely stable over time. The team has grown in expertise and reliability to the point where one dedicated agent now attends our annual gathering in Switzerland every year. Their support continues to exceed our expectations.

      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.
