The Core Creative Challenge

B2B SaaS is sold on outcomes not features, founders show feature demos; buyers want to see 'what problem disappears when I use this'. The ad must answer: what do I get in 7 days that I don't have today?

What Separates Winners From Wasted Spend

Specificity wins. 'CRM for freelance designers' outperforms 'CRM for everyone'. The more specific the ICP in the ad headline, the lower the CAC.

The FluxNote Workflow for This Vertical

Write a 5-bullet brief: ICP, problem, solution, proof stat, CTA → FluxNote generates animated demo video with screen-capture-style UI mock + karaoke captions → test 3 hooks per week → iterate on winner

The Mistake That Burns Budgets

Running LinkedIn ads before you've validated ICP with 10 paying customers, LinkedIn's high CPCs ($8 $15/click) destroy runway if you're still finding product-market fit
