At the seed stage startups stage ($500k–$3M raised (institutional seed round)), paid marketing has a completely different job than it does at Series B. Here's exactly what that job is, how much to spend, and the most common mistake that burns seed stage startups budgets.

Platform & Channel Strategy
Platform recommendation: Test 2 platforms simultaneously: Meta (for consumer or SMB products) or LinkedIn (for B2B). Allocate 60% to primary channel, 40% to secondary.
Cut the loser after 45 days.. Video strategy: Produce 3–5 video ads per week based on learnings from pre-seed testing.
Each video tests one variable (hook, format, CTA). Winning ads should stay live for 4–6 weeks before refreshing..
Creative format: Production quality starts to matter — invest in 5–10 second hook quality. Karaoke-style animated captions dramatically increase watch time on Meta/TikTok (85% of video is watched without sound).
FluxNote handles this automatically..
What to Measure (and What to Ignore)
CAC (cost to acquire a paying customer), payback period (how many months of revenue to recover CAC), and Month-1 retention. Target: payback period under 6 months for consumer, under 18 months for B2B.
What Not to Do at This Stage
Don't expand to a 3rd or 4th channel before you've proven your first 2 channels. Don't hire a marketing team — the founder or a growth contractor should own paid at seed. Don't optimise for CPMs or CTRs — only CAC matters.
The Founder Trap
Confusing 'the algorithm is learning' with 'this channel doesn't work yet'. If a Meta campaign has 500+ link clicks and no conversions, it's a messaging or landing page problem — fix those before blaming the channel.
