What are B2B Lead Generation Services?

B2B lead generation services streamline the process of attracting potential customers through targeted campaigns, customer lists, and market research. It’s vital to choose a provider that offers quality leads, understands your sector, and can engage your target market effectively.

The right provider will deliver a consistent flow of interested leads and craft campaigns that resonate with your ideal customer profile.

What results can I expect for the Lead Generation services?

You can expect to see approximately 2-10 meetings per week, though results may vary based on your offer, industry, Ideal Customer Profile (ICP), buyer persona, and number of outreaches.

Are the B2B lead gen services GDPR compliant?

Indeed, Jolly Marketer uses legitimate interest in accordance with Article 6(1)(f) of the GDPR as the legal basis for communicating with prospects and offers all recipients an easy opt-out option to unsubscribe from further communications and protect their data.

What is a Fractional CMO and when does my company need one?

A Fractional CMO is a senior marketing executive who joins your team part-time—on site or remotely—to provide C-level strategy, leadership, and execution without the cost of a full-time hire. You typically need one when you’re scaling fast, entering new markets, or lack experienced marketing leadership to align brand, demand generation, and revenue operations. The result: faster growth, lower risk, and immediate strategic impact.

How does Jolly Marketer’s Fractional CMO engagement work?

We offer modular, month-to-month packages tailored to your growth stage—ranging from a few focused days per month to interim CMO cover. Each package comes with clear deliverables, KPI targets, and built-in knowledge transfer, so your internal team can run the playbook long after the engagement ends. No long-term contracts, full budget transparency, and measurable results from day one.
