Belkins Reviews & Testimonials

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.

Lead Generation Review from Yana Okushko
Partnering with DMT Business Development turned out to be a real game-changer for us. Their team didnt just deliver leads they brought in the right conversations that actually converted. Within a short time, they secured 25 qualified meetings that had a direct impact on our pipeline and revenue. What stood out most was their professionalism - clear communication, full ownership of the process, and the feeling that they were part of our internal team rather than an external vendor. Their proactive mindset and attention to detail made every stage of the collaboration smooth and effective.

Applied Tech's Review Sourced from Google
We have been working with EBQ since July of 2024. It has been a seamless and rewarding experience, thanks to their exceptional project management and commitment to timely delivery on multi-project fronts.From the outset, their team demonstrated a clear understanding of our objectives, has maintained open communication, and has provided regular updates on progress.Milestones have been met with precision, and any challenges have been addressed proactively, ensuring the projects stay on track. Deliverables have not only been completed ahead of schedule but also have often times exceeded our expectations in quality and attention to detail.Their professionalism and dedication has instilled confidence throughout the process, making them a trusted partner for ongoing and future collaborations.
Sarah Becherer's Review Sourced from Google
Worked with EBQ on a sales outsourcing project for 6 months in 2024. Can't say enough positive things about how attentive, friendly, and responsive the team is. They're organized and excellent problem-solvers. Due to the nuances of our business and sales process, it ultimately wasn't a long-term fit, but I would highly recommend EBQ for cold-calling and appointment-setting for B2B software or managed services. Shout out to Dante who was with us since the beginning – you rock!
Rodane Williams's Review Sourced from Google
I contracted EBQ for BDR augmentation services for a period of three months, and the results were extremely disappointing. Despite their promises, they failed to schedule even one initial meeting with potential clients. It was clear from the start that they didn’t fully understand my organization, our business needs, or how to properly present us to potential leads.Instead of delivering on their commitment, they merely provided a list of cold calls that didn’t meet our business requirements at all. The leads were irrelevant, poorly targeted, and demonstrated a lack of research or effort. Despite their failure to achieve any tangible results, they had the audacity to demand thousands of dollars in funding for what was essentially a useless service.Overall, I found their approach disorganized and out of touch with our goals, making this engagement a waste of time and money. I would not recommend their services to anyone looking for real results.

Simon Akwasi Agyei's Review Sourced from Google
I like your services, however it will be of a great help if you give an option where you have data of phone numbers already, where someone can do a bulk messaging to.Also, my account was restricted for reminding a client of a bill they supposed to pay, which is quite not fair...I don't remember being given a note that you can't sent reminders on bills.
Abdul-Rahaman Abdul-Razak's Review Sourced from Google
I organized an important program which requires a draft of a name as sender's name. To my surprised, you never fulfilled that for me. I complained thinking of having a redress and was ignored. If you have any doubt of your client, you have several ways of getting to know him better. In as much you do business, the customer has a right.Though I have really enjoyed your services earlier before that incident.
