The B2B SaaS Demand Gen Playbook for 2025: What Still Works (And What Doesn't)

What's broken (and why)

Cold email at scale stopped working when inboxes got smarter and sequences became ubiquitous. Every SaaS founder and their agency is running the same 5-step Lemlist sequence with 'Hey {{first_name}}, I noticed you raised a round' as the opener. Buyers have trained themselves to delete these on sight. Similarly, LinkedIn has become pay-to-play at a level that's pricing out smaller teams, and the CPL from paid social is increasingly difficult to justify at early stages.

• Cold email response rates now average under 2% across B2B SaaS
• LinkedIn CPM costs have increased 38% since 2022
• AI-generated content is flooding Google, making organic traffic harder to earn
• Buyers complete 70% of their research before speaking to sales

The channels that are working right now

Demand generation in 2025 is about creating genuine authority in a specific niche — not broadcasting to a broad ICP. The companies doing this well have made a deliberate choice to own a specific conversation in their category. They publish point-of-view content that challenges assumptions, not SEO-optimised listicles. They show up where their buyers actually are — specific Slack communities, niche newsletters, LinkedIn via personal founder brands — not where they hope their buyers are.

The community and dark social play

A significant portion of B2B buying decisions now happen in channels you cannot directly track — Slack groups, WhatsApp threads, Discord servers, private LinkedIn conversations. This is what practitioners call 'dark social'. The strategy here isn't to infiltrate these communities with promotional content; it's to become the person that community members recommend when someone asks 'who should I talk to about GTM / demand gen / RevOps?'. That only happens through genuine contribution over time.

Building your 2025 demand gen stack

Rather than prescribing a single framework, the right approach is to identify where your buyers are concentrated, pick two or three channels you can execute with genuine quality, and go deep rather than wide. Spreading thinly across six channels is the most common mistake. One channel executed brilliantly — an owned newsletter, a podcast, a LinkedIn presence with genuine POV — will outperform six mediocre ones every time.
