Is TikTok right for my B2B invoicing tool?

No — likely the wrong primary channel. Across the founder case studies, zero B2B founders used short-form video as their primary growth engine, and the B2B playbooks (Breaking B2B, Rob Walling) point the same way. Focus on these instead:

  1. 1
    X (Twitter) & Reddit — designers congregate here. Shipper built in public on X and engaged the right subreddits.Shipper$25.6K MRR
  2. 2
    Competitor-alternative SEO — freelancers search for simpler, cheaper alternatives to the incumbents. YouForm won them with a one-click migration tool.YouForm$11K MRR
  3. 3
    Connector partnerships — instead of chasing designers one by one, Lancer recruited coaches with lifetime commissions to recommend it.Lancer$10K MRR in 4 months

The hard way, or this way.

The hard way
  • Watch hundreds of hours of interviews, conference talks and guru lectures
  • Hope the episode you watched applies to you
  • Generic advice: "just post on TikTok"
  • Motivation, then Monday-morning paralysis
