- Stepped conversation flow: context gather → unit economics → channel versus blended CAC
- Works from estimates when exact attribution is incomplete
- Example scenario: 6-month organic content channel at $15K/month spend
- Frames decisions with blended LTV, ARPU, margin, and MoM ARR growth goals
- PM-style prompts for customers per month and per-channel CAC inputs
- Example flow uses 6-month channel horizon and ~75 customers/month organic illustration

What problem does it solve?
You are unsure whether to increase spend on a channel like content or SEO without comparing channel CAC to blended economics and growth goals.
Who is it for?
Founder-operators with partial funnel data evaluating organic, paid, or outbound channels before the next budget cycle.
Skip if: Teams needing automated multi-touch attribution or ad-platform API optimization without a human judgment layer.
When should I use this skill?
User asks whether to scale, hold, or cut spend on a named acquisition channel and can supply spend, customers, and CAC estimates.
What do I get? / Deliverables
You leave with a reasoned scale, maintain, or cut recommendation grounded in unit economics and stated MoM or YoY targets.

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Grow analytics is the canonical shelf for channel efficiency, blended CAC, and ARR-linked scaling decisions. Analytics subphase fits structured CAC/LTV math and month-over-month growth targets against channel spend.
Where it fits
Compare hypothetical paid search versus content CAC before picking a first channel to test.
Check whether planned ARPU and margin support scaled spend at observed channel CAC.
Decide if $15K/month organic program merits more headcount given 75 customers/month at ~$200 CAC.
Rebalance channel mix when blended CAC drifts above LTV-backed payback tolerance.
How it compares
Conversation-first PM advisor—not a analytics dashboard integration or ad spend autopilot.

# Example: Channel Evaluation Conversation Flow This shows a full conversation using the acquisition-channel-advisor skill. --- ## Scenario: Evaluating Content Marketing Channel ### Step 0: Initial Request **User:** "Should we scale our content marketing spend? We've been investing in SEO and blog content for 6 months." --- ### Step 0: Context Gathering **Agent:** "Let's evaluate your content marketing channel. Please provide: **Channel details:** - Channel name: Organic content (blog, SEO) - How long: 6 months - Current monthly spend: $___ **Customer acquisition:** - Customers acquired per month (from this channel): ___ - CAC for this channel: $___ (if known) **Business context:** - Blended CAC (all channels): $___ - Blended LTV: $___ - Current MRR/ARR: $___ - Target growth rate: ___% MoM or YoY You can provide estimates if you don't have exact numbers." --- **User:** "Here's our data: **Channel:** - Organic content (blog + SEO) - 6 months running - Monthly spend: $15K (2 content writers + SEO contractor) **Acquisition:** - ~75 customers/month from organic - CAC: ~$200/customer **Business context:** - Blended CAC: $600 (across paid, outbound, organic) - Blended LTV: $3,000 (24-month avg lifetime, $125 ARPU, 75% margin) - Current ARR: $1.8M - Target: 10% MoM growth ($15K MRR growth/month)" --- ### Step 1: Unit Economics **Agent calculates:** ``` Channel CAC: $200 Blended CAC: $600 Channel is 3x more efficient than blended! ✅ Channel LTV: Need to confirm if similar to blended Blended LTV: $3,000 ``` **Agent:** "Great! Your content channel has CAC of $200 vs. blended $600—that's 3x more efficient. **Now let's confirm customer quality:** **Do customers from organic content have similar LTV to other channels?** 1. **Similar** — They stick around ~24 months like blended average 2. **Higher** — They churn less or expand more (longer lifetime or higher ARPU) 3. **Lower** — They churn faster or are smaller deals 4. **Unknown** — We need to analyze cohort retention data Choose a number." --- **User:** "2 — Higher. Content customers tend to be better educated about our product and have lower churn. I'd estimate 30-month avg lifetime instead of 24-month." --- **Agent calculates:** ``` Channel LTV (adjusted): - ARPU: $125/month - Lifetime: 30 months (vs. 24 blended) - Gross margin: 75% - Channel LTV = $125 × 30 × 75% = $2,812 Wait, that's lower than $3,000 blended? Let me recalculate using the LTV formula... Actually, if lifetime is 30 months: LTV = $125 × 30 = $3,750 gross revenue LTV = $3,750 × 75% margin = $2,812 net LTV Hmm, but blended LTV was $3,000. Let me ask for clarification. ``` **Agent:** "Let me confirm: If content customers have 30-month lifetime vs. 24-month blended, and same $125 ARPU: - Channel LTV = $125 × 30 × 75% = $2,812 But you said blended LTV is $3,000. Does blended include expansion (upsells/cross-sells) that content customers might not have as much of?" --- **User:** "Oh right, good catch. Blended LTV includes expansion. Content customers actually stick around longer (30mo vs. 24mo) BUT they expand less. So their total LTV is about $3,200—slightly higher than $3,000 blended." --- **Agent calculates:** ``` Channel CAC: $200 Channel LTV: $3,200 LTV:CAC = $3,200 / $200 = 16:1 ✅✅✅ (exceptional!) Payback Period: Monthly ARPU: $125 Gross Margin: 75% Monthly Gross Profit: $125 × 75% = $93.75 Payback = $200 / $93.75 = 2.1 months ✅✅✅ (extremely fast!) ``` **Agent:** "Excellent! Here are your unit economics for organic content: **Unit Economics:** - CAC: $200 - LTV: $3,200 - **LTV:CAC: 16:1** ✅✅✅ (exceptional—well above 3:1 threshold) - **Payback: 2.1 months** ✅✅✅ (extremely fast—well under 12-month target) This channel has outstanding unit economics. Let's check customer quality next." --- ### Step 2: Customer Quality **Agent:** "You mentioned content customers stick around longer (30mo vs. 24mo). Let's confirm quality metrics: **1.
