1. What Is B2B Lead Generation (and Why It’s Harder in 2025)

B2B lead generation is the process of attracting, capturing, and qualifying potential business customers who are likely to purchase your product or service.

Why 2025 Is a Different Game

1. Digital-first buyers: Gartner predicts 80 % of B2B sales interactions will take place online by 2025.
2. Data privacy & cookieless future: Third-party cookies are fading; first-party and intent data reign.
3. Noise overload: 300B emails sent daily, 8M blog posts monthly—harder to stand out.
4. AI arms race: Companies adopting AI enjoy 50 % higher MQL-to-SQL conversion (PepperInsight client data).

2. Market Landscape & Size

Key takeaway: Budgets and expectations both rising. Efficiency becomes the competitive moat.

3. Lead-Gen Framework: From TOFU to Revenue

TOFU (Top-of-Funnel) ➜ MOFU ➜ BOFU ➜ SQL ➜ Closed-Won is still valid, but successful 2025 teams add three accelerators:

1. Intent Data Layer – Real-time behavioral signals.
2. AI Scoring Engine – Dynamic qualification.
3. Revenue Loop – Post-sale expansion data feeds back into TOFU.
