Most startup user acquisition campaigns fail for the same 2–3 reasons. Here's the complete playbook: budget breakdown, ad sequence, platform timing, and the one thing that separates campaigns that compound from ones that just burn money.
Goal, Timeline & Budget
| Feature | Details |
|---|---|
| Goal | Scale paid user acquisition to a predictable, repeatable CAC at volume |
| Timeline | Ongoing — user acquisition is never 'done'; optimise continuously |
| Budget breakdown | Testing phase (first 60 days): $50–$200/day testing 8–12 creative variants |
| Scaling phase | concentrate 70% of budget on top 2 performing creatives |
| Refresh phase (every 3–4 weeks) | retire fatigued creatives, introduce new variants. |
Best Ad Formats for This Use Case
| Feature | Details |
|---|---|
| Best formats | UGC-Style Testimonial, Before/After Transformation, Hook Formulas (curiosity gap) |
| Platform timing | Meta: always on (largest scale potential) |
| search intent-based (adds incremental volume) | |
| TikTok | test if under-30 ICP (often 30–50% cheaper CAC than Meta for younger demos) |
| B2B only. |
The Systematic Approach
The only sustainable user acquisition system
- 1Create 5 hooks weekly,
- 2Test each at $10/day for 5 days,
- 3Kill anything above 1.5× target CAC,
- 4Scale anything below target CAC,
- 5Find out what made the winner work and make 5 more like it. Repeat.
What Separates Campaigns That Work
Creative velocity. The team that refreshes creative fastest wins the CAC war. At $10k/month spend, winning creative lasts 3–4 weeks before CTR decay. You need a new winner every month.
FluxNote Workflow for This Campaign
Build a 'creative testing factory': brief → FluxNote video → test → iterate. A founder or marketer can run 10 creative experiments per week. This velocity is what compounds — teams using manual video production can run 1–2 experiments/week.
