ProSpex

The creative specialist in B2B lead generation.

ProSpex is a creative partner focused on generating B2B leads. We’re convinced that closing a deal grows out of a genuine working relationship. That trust typically builds over the course of about 7 to 9 meaningful touchpoints with the right contacts, until the decision to do business becomes clear. As a result, classic “cold outreach” campaigns aren’t effective anymore. Instead, we design original campaign concepts that release knowledge step by step to your target audience.

We’ve been working with Prospex for a while now, and we’re very happy with the collaboration. The team thinks proactively, responds quickly, and understands how complex B2B sales works. Thanks to their combination of strategic advice, thought leadership, and targeted outreach, we’ve been able to have valuable conversations with the right decision-makers. Communication is smooth, commitments are kept, and they’re constantly looking at ways to further improve results. A great partner for organizations that are serious about driving commercial growth.

Great company to work with. The outbound campaign Prospex runs for us has become an integral part of our sales strategy. Thanks to the ongoing fine-tuning of our target audience, we’ve seen a big increase in conversions from sales appointments. Only thing to watch out for: the coffee machine wasn’t refilled with milk during either of our two visits!

I started at Prospex as an intern, and I eventually had the chance to stay on—something that really says a lot about how seriously they take keeping talent within the company. These days, I mainly focus on building and managing automations within our current and new processes, so we can make both customer workflows and internal processes more efficient. Data plays a big role in all of this: from tracking ICP scores to keeping customer statuses clear and up to date—everything comes down to making sure the information is accurate and ends up in the right place. What I value most is the freedom you get to come up with solutions and improve processes. The atmosphere is great, and coworkers are open to new ideas. Since Prospex is still growing, not all processes are fully set in stone yet—but that’s exactly what makes it such a great place for anyone who likes to think along and help build how things can be even better.
