How far out can you fund payback? - **Rebills make going negative rational,** but only with a base of rebill cash coming in and a real LTV model. Stefan suggests a fractional CFO. - **Low-LTV brands must be first-order profitable,** so they win on acquisition efficiency, creative cost and marketing moments, not by outbidding. - Expect CPA to rise as you go broader or the market (TAM) is small. Keep fighting it even when you accept it. ## Details **Rebill math (Stefan Georgi, telehealth peptide funnel, 2024).** Competitors' data suggested ~$2,000 LTV over six months at ~50% margin, so ~$1,000 extra gross profit per customer, or ~$166 a month after allowing for people who don't rebill.[^1][^2] At 1,000 new customers a day, month two adds ~$4.98M of gross profit with no ad cost. At 100 a day it adds ~$498K.[^2] He says this is why SaaS companies pay a lot to acquire, and why Agora (the financial publisher) famously runs negative for months.[^2] One real day: 17 sales at a $174.76 CPA against a ~$154 breakeven lost ~$340 on new customers. Rebills that day netted ~$1,100 (~$220 each), so the day made ~$760.[^3] In theory he could ignore a $300–500 CPA, but only with "a foundation of rebills coming in first" and a model built by a CFO or fractional CFO.[^4] Going negative lets you buy more customers and dominate a market. CPA still rises as you go broader (Facebook to billboards) or saturate a small TAM, so keep optimising it.[^4][^5] **Market CAC (Taylor Holiday and Joy Sharma, CTC, Aug 2026).** Through Statlas, CTC can see what brands in the same industry bid and convert at. Joy recalls clients asking for more volume at better efficiency while a competitor 10x their size runs a CAC *above the client's AOV*.[^6] Taylor's framing: - Meta is an auction, and ad quality is only one input. If someone will pay twice as much for the same conversion, they get the delivery.[^13][^7] - His example is IM8, with a ~$308 CAC on an AOV roughly two-thirds of that.[^7] - So much of the speed game is financing, judged against a deep understanding of payback. How far out you can get someone to finance acquisition sets the business's velocity, and that suits high-LTV and subscription brands.[^7][^8] **The other side: low-LTV brands (Taylor's 2026 keynote).** Taylor's three cases (Skullcandy, The Normal Brand, Spiral Bible) all have weak LTV and mediocre margins, so they must be first-order profitable on Meta "or they're dead". He means no 0.2 CAC-to-LTV ratio with four-year payback and no venture debt.[^9] He warns that copying LTV outliers like Grüns and IM8 tells most founders they don't have what it takes.[^10] Around $20–70M, DTC-only brands hit a fork: keep CAC profitable and slowly shrink acquisition, or raise CAC to grow and watch profit fall.[^11] His answers (cheaper creative supply, marketing moments, new distribution) are in [[creative-cost-per-ad-economics]], [[marketing-moments-calendar]] and [[demand-creation-vs-demand-capture-channels]]. **Subscription apps on cold traffic.** For a small wellness subscription app, Stefan expects a quiz funnel with a trial to run negative for a couple of months before rebills catch up.[^12] ## Disagreements / caveats - **Hormozi's 30-day payback rule** ([[cac-payback-and-30-day-cash]]) is the opposite stance for bootstrapped businesses. Stefan's and IM8's approach needs rebill cash or outside financing. Pick based on your cash, not ambition. - Stefan's LTV came from *competitors'* six-month data before his own cohorts matured. That makes it an estimate.[^1] - "Market CAC" depends on Statlas data that only CTC can see. Treat its competitor numbers as anecdotal. ## See also - [[funnel-economics-dirty-math]] — the day-zero numbers this builds on - [[ltv-to-cac-by-human-touchpoints]] — Hormozi's LTV:CAC targets - [[membership-churn-benchmarks-and-ltv]] — how churn changes LTV [^1]: yt:9CR76lix638 @ 41:54 — Stefan Georgi [^2]: yt:9CR76lix638 @ 43:26 — Stefan Georgi [^3]: yt:9CR76lix638 @ 48:06 — Stefan Georgi [^4]: yt:9CR76lix638 @ 49:37 — Stefan Georgi [^5]: yt:9CR76lix638 @ 51:09 — Stefan Georgi [^6]: yt:Z9rcSM01fv8 @ 08:11 — Joy Sharma [^7]: yt:Z9rcSM01fv8 @ 08:57 — Taylor Holiday [^8]: yt:Z9rcSM01fv8 @ 09:48 — Taylor Holiday [^9]: yt:bqJElruBvjE @ 04:43 — Taylor Holiday [^10]: yt:bqJElruBvjE @ 03:10 — Taylor Holiday [^11]: yt:bqJElruBvjE @ 16:06 — Taylor Holiday [^12]: yt:FQe6eOTMhU4 @ 52:56 — Stefan Georgi [^13]: yt:Z9rcSM01fv8 @ 08:11 — Taylor Holiday
