Final prompt (paste into Veo / Gemini / Flow):

Premium commercial look, photorealistic, vertical close-up at counter height of a matte black ceramic pour-over coffee dripper with a thin polished copper rim, sitting on a clear glass carafe on a walnut kitchen counter by a window in the early morning just after sunrise. A thin stream of dark coffee trickles from the dripper into the carafe while soft steam curls up from the rim, and the dripper and carafe turn a slow quarter turn. Slow dolly in, 85mm-style telephoto feel, shallow depth of field with the kitchen background in soft bokeh. Soft low-angle morning sunlight from a window on the left with gentle fill and a warm rim light catching the copper, palette of matte black, warm copper, honey-brown walnut and soft cream highlights, calm and quiet mood. Real-time pace; the final second holds still on the dripper's front.
Audio: close, clear sound of coffee trickling into a glass carafe, a faint soft drip, quiet low morning room tone, no music.
Negative prompt: text, logos, letters, labels, hands, people, clutter, reflections of people, plastic look

Settings: 9:16, 8 seconds, audio on.

Pack: `references/pack-product-shots.md`.

Three options

1. PS-09 Strawberry Milkshake Product and Infographic. A ready-made premium cold-drink hero shot: seamless pastel backdrop, realistic condensation droplets and "premium café advertisement" styling, which is exactly the look a chilled cold-brew can needs.

2. PS-02 Luxury Chocolate Ad Still Life. The only prompt in the pack that is a full ad layout with on-image copy, but you would have to delete its placeholder copy and invented logos and rebuild most of the props.

3. PS-01 Premium Beverage Advertising Photography. Written for a beverage-brand hero ad and works from your attached references, but the prompt is only one line long, so lighting and composition would come from what you attach.

Pick: PS-09

What to attach. Image 1: a clear, front-on photo of your real Northbound can, logo facing the camera.

Adapted prompt (4:5 Instagram ad)

Image 1: product photo of the Northbound cold-brew coffee can. Use this exact can.

A vertical 4:5 Instagram feed ad. A high-quality professional product photograph of a premium cold-brew coffee can, the 330 ml matte navy aluminium can from Image 1 with its white logo, standing upright and centered against a soft pastel pink seamless studio background. Preserve the can's exact shape, proportions, matte navy finish, white logo and label from Image 1; do not redesign it, recolour it or add any new graphics to it. The can sits on the same seamless surface with a few clear ice cubes and a small scatter of dark roasted coffee beans at its base. Realistic condensation droplets cover the can with soft reflections from the studio lights. Elegant soft lighting creates subtle natural shadows beneath the can. The can fills about 55% of the frame height in the lower two thirds of the image, logo facing the camera.

Text: the headline "Cold. Bold. Northbound." across the top third of the image, centered, in a bold clean white sans-serif with generous letter spacing, large enough to read on a phone. Render this headline exactly once, spelled exactly as written. Apart from the can's own logo from Image 1, no other text, no prices, no taglines, no extra logos, no watermark.

Ultra-sharp focus, DSLR macro beverage photography, premium café advertisement style, hyper realistic, clean commercial composition, 8K.

Tool settings: aspect ratio 4:5; in AI Studio or the API also set the output resolution to 2K so the headline stays sharp.

Adapted: subject swapped from a strawberry milkshake in a glass to the Northbound can, Image 1 reference and preserve-the-product line added, 4:5 aspect ratio and headline added, the original's second (infographic) paragraph removed.

BRAND BRIEF — Northwood Beard Oil

1. Positioning
We help men 28–45 with full beards stop smelling like drugstore musk. We can do this because a third-generation perfumer blends 14 natural notes other beard brands will not pay for.

2. Audience snapshot
- Situation: has worn the same $9 oil for years; wife or colleague has commented on the smell
- Trigger: a wedding, a new job, or the bottle running out
- Tried: "premium" brands that still lean on synthetic musk
- Fears: smelling like a teenager's locker; paying $40 for marketing

3. Promise
A scent people ask about, not one they step away from — within the first week.

4. Voice rules
Do: short declaratives ("Three notes. Zero musk.") / Don't: "elevate your grooming ritual"
...
6. Instruction for future prompts
Use this brief. Never use "elevate", "curated", "ritual". Always name a specific scent note.

Skeptic re-read: "Third-generation perfumer" is doing all the work — if it is not provable on the site, the positioning collapses to "nice smell". Holds only with proof.

Proposal — Loom · AE Onboarding Playbook Pilot

On Tuesday you said the eight incoming AEs have "no shared playbook" and that "ramp is going to kill us by Q2". You put current ramp at "14 weeks if we're honest" and a loaded AE at "about $140k".

Success: first cohort productive — first closed deal — inside 6 weeks instead of 14.

You said → What we do about it
"no shared playbook" → two-week build with your top two reps, delivered as a 5-day onboarding track
"ramp is 14 weeks" → week-1 to week-6 milestones with a manager checklist, so ramp is measured, not felt
"we tried a doc once and nobody read it" → every module ends with a recorded role-play a manager reviews in ten minutes

Timeline: build weeks 1–2; cohort onboarding weeks 3–8; review week 9.

Investment: $18,000. Payback: 8 AEs × 8 weeks saved × ($140k ÷ 52) ≈ $172k of ramp cost recovered. Breakeven at one AE.

Next step: a yes by Friday the 13th to start the build on the 16th.
Risk you raised: "our reps won't do homework" — modules are under 20 minutes and done live with the manager.

Walkthrough
Lines 1–8 pull `items` from the cache with no validation. Lines 10–18 loop and sum `item.price * item.qty`. Lines 20–22 return the total as a float.

Assumptions
1. The cache always returns a list → None raises AttributeError at line 10.
2. Every item has `price` and `qty` → legacy rows without `qty` raise KeyError mid-loop; partial sums are lost.
3. `price` is numeric → a string price silently concatenates on some paths. Dangerous.
4. The list is not mutated during iteration → a concurrent cache refresh mutates it; totals come back inconsistent with no error. Dangerous.
5. An empty list means a zero total → returns 0 silently; callers cannot tell "no items" from "free". Dangerous.

Verdict on your concerns: concurrency — unsafe; error handling — none; empty list — silent zero.

Tests
- items = None → a clear 500 with a logged cause
- one item missing qty → validation error naming the item id
- 10k items during a cache refresh → a consistent snapshot or a retry

Confirm the diagnosis and I will propose a patch.

Top 5 unmet needs (67 interviews)

1. Onboarding takes too long — 41 customers
   "I gave up before my first usable result." (I-12) · "Two evenings to set up something I wanted to try in ten minutes." (I-38)
   Trigger: trying the product between meetings, on a phone.
2. Sharing with the team is friction — 33
   "I ended up screenshotting the dashboard into Slack." (I-05)
3. Integration with the existing stack — 29
4. Pricing surprise in month two — 24
5. Progress does not sync between devices — 18

Early signals
- Offline mode — I-12, I-38, I-51: "I'd pay for it to just work on the train." Unprompted in three separate interviews; not noise.
- Public API — I-22 only.

Contradictions
- 14 customers want fewer notifications; 9 want a daily nudge. Both groups are under 30 days in.

Say vs. want
- Say: "more features." Want, from behaviour: the three they already use to be faster. (I-07, I-44)

Follow-ups for next round
1. "What did you expect to have working within ten minutes?"
2. "Who else looks at this, and how do they see it today?"

Convergence
1. D2C ed-tech CAC has risen 30–40% over 18 months — McKinsey (n=200 companies), a16z note, Coursiv S-1 excerpt. Representative: "blended CAC up 36% YoY" (McKinsey). Confidence HIGH.
2. Subscription outperforms one-time pricing for content products — all four. Confidence HIGH.
3. Trial length matters less than trial-to-paid messaging — three of four; the fourth is silent. Confidence MEDIUM.

Biggest disagreement
McKinsey: auto-renewal optimisation is the largest revenue lever. a16z: cohort-driven retention beats it. Stronger side: McKinsey — 200-company sample versus a16z's four anecdotes, and McKinsey's data is 2025 while a16z's examples are 2023.

The question none of them answers
What happens to LTV when you send an honest reminder before auto-renewal. Likely gap: no operator has run it at scale, and the consultancies are paid by companies that do not want to.

Read or measure next: your own month-3 retention by acquisition channel — every source above assumes it is uniform, and for your decision it is the number that matters.

VOICE OF CUSTOMER — GrowNest (30 reviews, App Store, 3 competing apps)

Top 5 pains
1. "it was fine in the shop and now it's dropping leaves" (11)
2. "I can't tell if I'm overwatering or underwatering" (9)
3. "every blog says something different" (7)
4. "the reminders nag me but never tell me why" (5)
5. "I've killed three of these already" (4) — EARLY SIGNAL: one reviewer, "I'd honestly given up on plants"

Top 5 dream outcomes
1. "finally know what's wrong before it's too late" (8)
2. "it just told me: less water, more light. done." (6)
3. "my monstera actually grew a new leaf" (5)
...
Recurring words: dropping, yellowing, overwatering, "no idea", nag, finally, survive, confident, "too late", simple
Words to avoid: ecosystem, curated, holistic, "plant parent", elevate

Subject: Your pricing page is lying to you
Preview: Three founders raised prices last month. Two regret it.

Headline: The pricing change that costs more than it earns

1. The claim — Raising prices 20% sounds like free margin. For two of three founders I spoke to this month it cut net revenue, because the churn arrived three months later and nobody connected it.
2. The mechanism — Annual customers do not leave on day one. They leave at renewal, which is after you have already celebrated.
3. The numbers — Founder A: +20% price, −11% net revenue by month 5. Founder B: +15%, +9% — the difference was a grandfather clause.
4. What I would do — Raise for new customers only. Measure renewal cohorts for two quarters before touching existing plans.

CTA: Reply with your last price change and the month you measured it. I will tell you if you measured too early.

Cuts the author will push back on: the opening anecdote about the coffee shop (300 words, no number); the second example that repeats the first; "I think" ×6.

Voice rules

- Sentence length: 4–10 words. Never a sentence over 14.
- Tone: dry, mildly self-deprecating, never preachy. "Okay, controversial:" / "Weirdly, the most-asked question this month" / "Sorry. Also not sorry."
- Words used often: actually, okay, weirdly, notes inside, for a real face
- Words never used (peers use them): journey, elevate, unlock, glow-up, self-care, ritual, holy grail, obsessed
- Emoji: one at the end, never mid-caption. 🌿 or 😌.
- Hooks: a contrarian observation stated flat, never a question.
- Closes: one short verdict, no CTA.

New captions (launch week)
1. Most niacinamide serums are water with a marketing budget. Ours isn't. 🌿
2. Okay, controversial: your skin does not need 12 steps. It needs 3 that work.
3. Tested the new cleanser on a real face for 6 weeks. Notes inside.
4. Weirdly, the most-asked question this month: "safe during pregnancy?" Yes.
5. Discontinued the toner. It wasn't pulling its weight. Sorry. Also not sorry. 😌
...
Drift check: #7 uses a question hook; #9 runs 16 words. Cut both.

Weekly briefing — AI search and research tools, 29 Apr – 6 May

Edited draft

AI lessons that take 15 minutes a day. Used by 12,000 professionals in 40 countries. Start your free 5-day trial.

Change log
- "a revolutionary AI-powered learning experience" → "AI lessons that take 15 minutes a day" — "revolutionary" is a tell; 15 minutes is a number the reader can picture
- "empowering professionals worldwide to thrive" → "used by 12,000 professionals in 40 countries" — abstraction replaced with proof
- "Begin your transformative journey today" → "Start your free 5-day trial" — the actual offer is more persuasive than the metaphor
- cut "seamlessly", "cutting-edge", "unlock" — adjectives with no referent
- "trusted by teams" → [NEEDS NUMBER] — kept, but it needs a count or a name

Weakest remaining line: "40 countries" is impressive only if the reader is outside the US; consider replacing with a named company.
