Real answer · 3.2s
Is TikTok right for my B2B invoicing tool?
No — likely the wrong primary channel. In the 90-case dataset, zero B2B founders used short-form video as their primary growth engine. Focus on these instead:
- 1X (Twitter) & Reddit — designers congregate here. Shipper built in public on X and engaged the right subreddits.Shipper$25.6K MRR
- 2Competitor-alternative SEO — freelancers search for simpler, cheaper alternatives to the incumbents. YouForm won them with a one-click migration tool.YouForm$11K MRR
- 3Connector partnerships — instead of chasing designers one by one, Lancer recruited coaches with lifetime commissions to recommend it.Lancer$10K MRR in 4 months
