Growth plan for David Donahue, 4 Oct 2026
Scale spend. Hold CAC.
Founded in 1972, David Donahue sells its dress shirt at $175.00. The plan tests creator angles on that one price, kills losers early and protects one number: a target CAC of $84. Everything else follows from that.
- Target CAC
- $84
- New ads a week at peak
- 20
- Creators live by week six
- 10
- Test spend, six weeks
- $24,000
Contents
10 chapters, then the gates and every number’s source.
01 The number
One number to protect: $84 CAC on a $175.00 shirt
The one number to protect is target CAC: $84, the guard line under a $140.00 ceiling. At a $175.00 shirt and a 15% first-order coupon, every test is judged against that number first. Spend scales only while CAC holds.
Protect
Target CAC: $84 on a first purchase
Ceiling = average order × margin × (1 + repeat orders): $175 × 40% × (1 + 1) = $140.00. Guard line = 0.6 × $140.00 = $84.00. Across the ranges: $70.88 to $1,343.25.
Three moves
- Kill losers early: any ad that misses the $84 guard line stops inside its test week, and its budget moves to the next concept.
- One variable per test, so a shirt hook, a tie hook and a quarter-zip hook each get a clean read.
- Send every winner to a matching landing page, so the offer in the ad is the offer on the page.

02 Variety
Variety: shirts, ties and coats give each concept a hook
Each ad concept has to carry one reason to buy, one product and one price: a $175.00 dress shirt, a $135.00 silk tie or a $225.00 quarter zip. The site's own lines, "100% U.S. Pima cotton" and 15% off a first purchase, give the hooks. One variable changes per test.
| Reason to buy | Proof you already have | Ads (proposed) |
|---|---|---|
| U.S. Pima cotton | 100% U.S. Pima cotton | 5 |
| Stretch that moves with you | Woven from U.S. Pima cotton with stretch in a 100/2-ply twill | 3 |
| Free US shipping | Free US Shipping over $200 | 2 |
| 15% off the first order | First order? Enjoy 15% off with your signup coupon. | 2 |
| 60-day returns | Unworn items with tags may be returned within 60 days (30 days for sale items). | 2 |
| Founded in 1972 | Founded in 1972, David Donahue supports the hustle for success and tailoring the wardrobe to achieve it. | 2 |
| Same-day shipping before noon | Orders placed before 12 PM EST usually ship same day. | 2 |
| Total | The ad concepts tab | 18 |
Each row is a reason to buy that the brand already has proof for. The count is how many of the ads carry it: a reason with a single ad is a bet, not a pattern, and the next batch of concepts moves toward the reasons that win.
03 Disturbances
Risks: a $175.00 shirt sits under the $200 shipping line
| Disturbance | Likelihood | Impact | Owner | Gate (proposed) |
|---|---|---|---|---|
| A $175.00 shirt sits under the $200 free shipping line, so carts may stall short of checkout | High | Med | Both | Share of carts above $200 rises against the first-week baseline once the tie pairing page is live |
| Returns run 60 days on full price, 30 on sale, and can erase first-order margin before payback | Med | High | Your team | Returns by product reported monthly; stop scaling a shirt whose returns push CAC above $84 |
| No review count was collected, so ads may lack social proof for a $175.00 shirt | Med | Med | Me | Creator proof videos must beat the control ad on CAC within the first test weeks |
| Event tracking may misreport purchases, so CAC reads wrong from the first test | Med | High | Your team | Purchase events match orders in your store before week-one spend passes $3,000 |
| Creator tone drifts from "Luxury With Its Sleeves Rolled Up" into generic try-on content | Med | Med | Me | Each brief checked against the tagline before filming; off-tone videos never run as ads |
| Hit rate lands under the Assumption, so winners arrive late and CAC stays above $84 | Med | High | Me | Fewer than 2 winners from the first 20 concepts triggers a new round of hooks |
| Ad copy promises faster delivery than the 12 PM EST cutoff and UPS shipping allow | Low | Med | Both | No delivery claim runs unless it matches the shipping page word for word |
Scores are my read from outside the company, re-scored in week one with your data. Each risk has one owner and one gate that can be checked with a number, so nobody has to argue about whether it happened.
04 The ceiling
The ceiling is $140.00; the guard line is $84.00
| Line | Value | Status |
|---|---|---|
| Average order | $175 (range $135.00–$995.00) | Assumption Range from the site product prices (Published); the midpoint is a guess |
| Gross margin | 40% (range 35–45%) | Assumption Replace in week one |
| Repeat orders after the first | 1 (range 0.5–2) | Assumption Replace with cohort data in week one |
| Margin per customer, all orders | $140.00 | Calculated Average order × margin × (1 + repeat orders) |
| Guard line for CAC | $84.00 | Calculated 0.6 × the margin per customer |
The math, with the assumed lines
Ceiling = average order × margin × (1 + repeat orders): $175 × 40% × (1 + 1) = $140.00. Guard line = 0.6 × $140.00 = $84.00. Across the ranges: $70.88 to $1,343.25.
Range across the assumptions: $71 to $1,343.
The $140.00 ceiling is $175 × 40% × (1 + 1). The $175.00 shirt price is published; the margin and repeat orders are guesses. Week one replaces them with your numbers.
The ceiling is a range, not one number: the most a new customer can cost before shipping and packaging, which I do not have. Replace the guessed lines with yours and every figure below recalculates.
05 Test ramp
Six test weeks cost $24,000 before we scale winners
| Week | New ads × budget / ad (proposed) | Weekly test spend | Cumulative | Creators posting | CAC target (proposed) |
|---|---|---|---|---|---|
| 1 | 12 × $250 | $3,000 | $3,000 | 0 | $84 |
| 2 | 12 × $250 | $3,000 | $6,000 | 2 | $84 |
| 3 | 12–20 × $250 | $4,000 | $10,000 | 4 | $84 |
| 4 | 12–20 × $250 | $4,000 | $14,000 | 6 | $84 |
| 5 | 20 × $250 | $5,000 | $19,000 | 8 | $84 |
| 6 | 20 × $250 | $5,000 | $24,000 | 10 | $84 |
Six test weeks, $24,000 in total. Weeks 1 and 2 run 12 ads at $250 each, $3,000 a week. Weeks 3 and 4 run 12–20 ads, $4,000 a week. Weeks 5 and 6 run 20 ads, $5,000 a week. Cumulative spend reaches $24,000 by week six. Proposed.
The math. Week 1: 12 × $250 = $3,000; Week 2: 12 × $250 = $3,000; Week 3: 16 × $250 = $4,000; Week 4: 16 × $250 = $4,000; Week 5: 20 × $250 = $5,000; Week 6: 20 × $250 = $5,000. Total $24,000 (96 ads × $250). A range such as 12–20 counts as its midpoint.
Weeks one and two test what the brand already has, rewritten per reason to buy. From week three, creator videos enter paid only after they beat their own account median. A range of new ads counts as its midpoint in the spend column.
06 Volume
Volume: 20 concepts yield 2 winners, 80 concepts yield 8
More concepts means more winners, and winners are what lower CAC on a $175.00 shirt. At 20 concepts the plan expects 2 winners, adding $18,000 a month; at 80, 8 winners adding $72,000 a month. Hit rate and spend per winner are an Assumption.
| Concepts tested / month | Hit rate (assumed) | New winners / month | Spend each winner holds (assumed) | Added spend at target CAC |
|---|---|---|---|---|
| 20 | 10% | 2 | $300 / day | $18,000 / month |
| 40 | 10% | 4 | $300 / day | $36,000 / month |
| 60 | 10% | 6 | $300 / day | $54,000 / month |
| 80 | 10% | 8 | $300 / day | $72,000 / month |
The math. 20 concepts × 10% = 2 winners × $300 × 30 days = $18,000 a month; 40 concepts × 10% = 4 winners × $300 × 30 days = $36,000 a month; 60 concepts × 10% = 6 winners × $300 × 30 days = $54,000 a month; 80 concepts × 10% = 8 winners × $300 × 30 days = $72,000 a month.
The hit rate and the spend each winner holds are placeholders. The first thirty days of tests replace them with real numbers, and the table is recalculated the same day.
07 Allocation
$100,000 split across tests, winners, creators and pages
- Six weeks of creative tests on Meta
- $24,000
- 24%
- Scaling winners that hold the $84 CAC
- $46,000
- 46%
- Creator pay and product for the roster
- $20,000
- 20%
- Landing pages and tracking fixes
- $10,000
- 10%
Proposed split of the $100,000. Test spend is the $24,000 ramp; week-six results decide how much of the rest moves to winners.
The math. 24% × $100,000 = $24,000; 46% × $100,000 = $46,000; 20% × $100,000 = $20,000; 10% × $100,000 = $10,000. Sum 100% = $100,000.
This split is a proposal. It moves toward scaling as winners prove out, and toward testing when fatigue shows.
08 Channels
Meta first, because a $175.00 shirt needs a story to sell
| Channel | Open when (proposed) | Why wait |
|---|---|---|
| Meta | Week one, with 12 ads | Fastest place to test creator videos of a $175.00 shirt, one variable at a time. |
| TikTok | A Meta hook holds CAC at or under $84 for a full week | Creators already film outfit routines there; a quarter zip or silk tie fits the format. |
| Branded search | Meta winners start pushing shoppers to look up David Donahue | Captures the shopper who saw a $175.00 shirt ad and searches the name before buying. |
| Email signup | Meta traffic lands on the signup offer | The 15% off first purchase offer gives cold traffic a reason to leave an email. |
| YouTube | Two Meta winners hold CAC under $84 | Longer videos can show fabric, stretch and fit up close before a $175.00 purchase. |
A channel opens when its condition is true, not when the calendar says so. Until then the budget stays where the CAC is earned.
09 Payback
Payback: at $85 CAC a David Donahue customer needs a repeat order
Payback is the real constraint. At a $40 CAC a first order leaves $100.00. At $85 it takes repeat orders to leave $55.00. At $155 or $195 the customer never pays back, so we stop. A $175.00 shirt only works if the second order shows up.
Cumulative margin per customer, order by order, before CAC: $70.00, $140.00.
| CAC (scenario) | First-order margin | Year-one margin | Left after CAC | Payback |
|---|---|---|---|---|
| $40 | $70.00 | $140.00 | $100.00 | First order |
| $85 | $70.00 | $140.00 | $55.00 | After repeat orders |
| $155 | $70.00 | $140.00 | −$15.00 | Never: stop |
| $195 | $70.00 | $140.00 | −$55.00 | Never: stop |
The math. CAC $40: $140.00 − $40 = $100.00 left; pays back: First order; CAC $85: $140.00 − $85 = $55.00 left; pays back: After repeat orders; CAC $155: $140.00 − $155 = −$15.00 left; pays back: Never: stop; CAC $195: $140.00 − $195 = −$55.00 left; pays back: Never: stop.
Read each row left to right: the margin of the first purchase, the margin over the whole horizon, what is left after CAC, and the purchase on which the CAC is earned back. A scenario that never pays back is a stop, not a test.
10 Scope
Scope: shirts, ties and jackets in; your site and stock out
Covers
- Meta ad testing on shirts, ties, quarter zips and jackets
- Creator briefs, roster and the weekly video flow
- Landing pages matched to each winning concept
- Daily CAC, weekly learnings, monthly cohort payback
Doesn’t
- Your site build, checkout and product photography
- Event tracking: I spec it, your team builds it
- Inventory, UPS fulfilment and returns handling
- Anything outside paid social and creators
What this plan covers is what I can change inside the ad account and the creator program. Everything outside it is named on the right so nobody assumes it is handled.
Gates, written before spend, so stopping isn’t a negotiation.
| Day | Keep going if (proposed) | Stop or change if |
|---|---|---|
| Day 14 | Purchase tracking matches orders and the 12 ads from week one are live with a CAC read against $84 | Tracking still disagrees with orders; spend pauses until it matches |
| Day 30 | Winning concepts hold CAC at or under $84 while test spend keeps climbing along the ramp | No concept holds CAC under $140.00 after the first four weeks |
| Day 60 | Spend on winners scales and blended CAC stays at or under $84 for a full week | Blended CAC sits above $140.00 for two weeks running |
| Day 90 | Cohort payback shows first orders earning back CAC after repeat orders, as in the $85 case | Cohorts land in the never-payback range, at $155 or above |
Each gate is checked on its day with the numbers in the daily and weekly reports. If the stop condition is true, the spend stops and nothing renews until we talk.
What exists, what’s missing, and the order that’s forced.
| Piece | Exists today | Missing | Forced order |
|---|---|---|---|
| creative | Named pieces like The Moore Overshirt at $295.00 | Short creator-style videos built on one hook each | 1st |
| creators | Tagline "Luxury With Its Sleeves Rolled Up" sets the tone | Roster of ten creators across work, quarter zip and tie styles | 2nd |
| claims sheet | Own lines: 100% U.S. Pima cotton, 95% cotton, 5% spandex | One sheet tying each line to its product page | Week 1 |
| landing pages | 15% off first purchase and free shipping over $200 | One page per concept, starting with the shirt-plus-tie pair | 2nd |
| reporting | Return terms: 60 days full price, 30 days sale | Daily CAC view with returns netted by product | 1st |
The order is forced on purpose: creative and creators come first because they are what moves CAC, and everything else waits for that data.

Every figure on this page is listed here with where it came from. Fact means read on the site. Assumed and Proposed are Danilo’s own numbers, to be replaced in week one. Calculated is plain arithmetic on those, with the formula shown next to it.
Month one is where it starts.
In week one I read your product pages, build the claims sheet and spec the tracking with your team. The first 12 ads go live against the $84 target CAC, inside $3,000 of test spend. Losers die early.
