Netspore

Netspore is a market intelligence and lead generation agency that helps B2B organizations identify, research, and contact decision-makers within their specific target markets. The agency provides managed data services designed to address the inaccuracies and data decay often associated with broad-market B2B contact databases and automated scraping tools. The service is intended for sales leaders, marketing departments, and business development teams who require high-fidelity prospect data to support account-based marketing (ABM) and outbound sales strategies. Unlike automated platforms that offer access to static, pre-existing databases, Netspore utilizes a manual market mapping approach. The agency takes a client’s specific Ideal Customer Profile (ICP) and performs deep research to identify compatible companies and the specific individuals responsible for purchasing decisions within those organizations. Human-Verified Data Accuracy: The agency employs a multi-stage verification process that combines automated discovery with manual review by researchers to validate contact information, including professional email addresses and direct telephone lines, aiming for 99% accuracy. Custom ICP Mapping: Clients define specific parameters for their target accounts, and the agency identifies companies and decision-makers that match those exact criteria to ensure prospect compatibility. Strategic Market Research: The service maps the complete ecosystem of a target niche, providing visibility into primary accounts as well as organizations that are often missed by standard software-based searches. Decision-Maker Intelligence: The agency provides detailed insights into organizational structures and professional roles, assisting sales teams in navigating complex buying committees and identifying key stakeholders. Pipeline Efficiency: By managing the deep research and verification phase of lead generation, the agency allows internal sales teams to focus on outreach and closing rather than manual prospecting and data cleaning. Common use cases for Netspore include the creation of bespoke account lists for strategic outreach, the execution of market entry research, and the scaling of specialized outbound sales functions. By delivering a curated list of compatible prospects, the agency seeks to streamline the sales cycle and improve the response rates of B2B communications. The service is tailored for high-stakes enterprise sales where the identification of the correct decision-making unit is a critical requirement for business growth.

Nordic Sales Force

Everyone Should Have Access to Professional Sales Support A high-performing sales department requires experience, expertise, and professional sales leadership. Traditionally, this has been reserved for larger companies with commercial teams consisting of sales managers, team leaders, and skilled sales professionals. Nordic Sales Force was founded with the vision of giving businesses of all sizes access to this kind of setup. It all started with one person and a phone in January 2021. Just two years later, Nordic Sales Force had grown to more than 10 employees, helping B2B companies achieve their growth ambitions, even if they lacked the time, expertise, or resources to build and manage their own sales department. From booking qualified meetings to closing the deal, the team took ownership of the entire sales process. The company continued to grow over the following years, and in 2025 Nordic Sales Force was named a Børsen Gazelle for the first time. With growth of more than 857% during the qualifying period, the company ranked 18th among all Gazelle companies in Central Jutland. The following year, Nordic Sales Force was officially certified by B Mærket. In 2026, Nordic Sales Force reached 100 employees, now based across the company's offices in Aarhus and Copenhagen. The Copenhagen office also employs Swedish and Norwegian sales professionals, enabling the company to support B2B sales across Denmark, Sweden, and Norway.
