LinkedIn Review from Darina Yatsuk

Addlium is a focused and highly competent team with a strong understanding of LinkedIn marketing, B2B communication, and social selling. As a performance marketing agency, we especially appreciate partners who can connect their work with wider business and sales objectives rather than treating marketing channels separately. The Addlium team communicates clearly, approaches discussions in a structured way, and demonstrates a practical understanding of how companies can use LinkedIn to strengthen their positioning, reach relevant decision-makers, and create new business opportunities. Their expertise complements broader digital marketing activities, particularly for B2B companies with complex services and longer sales cycles. We also value their professional attitude and openness to collaboration. Addlium has built a clear specialization and a well-defined approach to LinkedIn, which makes them a reliable partner for businesses that want to develop this channel systematically.

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.

Software Development Review from Michael Meyer

We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!
