Substack for B2B Founders: A Pragmatic Take

Substack has emerged as the default platform for serious long-form thought leadership in B2B. Founders who write a substantive Substack consistently for 12+ months build deep audiences in their category. The investment is significant (1-2 hours per post, 1-2 posts per month) but the compounding brand effect is real.

Worth doing: founders who genuinely have a category point of view that is not yet captured elsewhere, founders who can commit to 1-2 substantive posts per month for 18+ months, and founders whose category audience is large enough to support a meaningful subscriber base (typically 5,000+ active buyers in the niche).

Not worth doing: founders who cannot commit to consistent cadence (sporadic Substack is worse than no Substack), founders whose category is so narrow that a Substack will never reach scale (better to focus on direct buyer relationships), or founders who write to satisfy ego rather than to share genuine insight (readers detect this quickly).

If you launch, treat it as a 24-month commitment minimum. The first 6 months produce no traction. Months 7-18 build audience slowly. Months 18+ start to compound. Most founders quit at month 6 because the early returns are flat. The ones who push through produce one of the most durable category-presence assets available.
