Marketing brief · from one collector to another · September 2026
Don't sell an app.
Sell the feeling of
knowing.
You said you're bad at this part. Good — the people who are "good at marketing" would sell CLCTN like software, and collectors can smell software being sold to them from across the room. The only voice that works here is the one you already have: a collector who built the thing he wanted, talking to another collector. This brief turns that voice into a system: one positioning, one message house, a copy bank you can paste, the loops built into the product, and the answers to every objection you'll hear.
Nobody wants a catalogue. They want the moment of knowing — what it is, where it is, who has it, what it went through — without the guilt of a spreadsheet they stopped updating in 2019. Every line of copy sells that moment. The app is just how you get there.
Execution lives elsewhere: channels in the growth plan, clips in the video playbook, the store page in the App Store brief, sequencing in the master plan. This is the what to say layer they all draw from.
01 · Positioning
One sentence you can
say at a record fair
For people who collect on purpose and are tired of not quite knowing what they have, CLCTN is a private catalogue that remembers — what each object is, where it is, who has it and what happened to it — unlike spreadsheets that die and marketplace apps that want to sell your stuff, because it's built hobby by hobby, keeps history instead of overwriting it, and never puts your shelf on a server.
The master line, and the lines under it
One line everywhere for a year. Repetition is the whole trick; alternating taglines is how small brands stay unknown. The master is chosen in Tweaks so you can see each one on the message house below.
MASTER · MY PICK
Know what you own.
Four words, a verb, a promise, and a quiet accusation: you don't, currently. Extends naturally: "…and who has it." Works on a screenshot, a sticker, a forum signature.
SUPPORT · THE ENEMY
The shelf, not the spreadsheet.
Names what they use today and why it fails. Best in community posts and video hooks, where naming the enemy earns a nod.
SUPPORT · THE PRIDE
Your collection, finally worth looking at.
Already on the website. The emotional line — pride, not utility. Best next to the 3D shelf, where it proves itself.
SUPPORT · THE TRIBE
For people who own things on purpose.
The identity line. Says who it's for by flattering them, and who it's not for without insulting anyone. Bio line, footer, end card.
02 · What it fixes
Five things every collector
has said out loud
Marketing that works starts from a sentence the customer already says, not one you'd like them to say. These five are the ones you'll hear in any forum within an hour. Each has its fix and the exact line to use. Lead with the pain, always — the fix means nothing until they've felt the problem again.
THE PAIN · IN THEIR WORDS
"I have a spreadsheet. I haven't opened it since… honestly, years."
Adding takes ten seconds, so it actually gets done
Photo first — the app proposes the pressing, the edition, the year; you confirm. The spreadsheet died because every entry cost two minutes and a decision about column names. Here the type already made the decisions.
→ "Point. Confirm. Done. Ten seconds, and it's on the shelf."
THE PAIN
"Who did I lend that to? It's been… a year? Two?"
A lending ledger both sides confirm
Lend with a due date. They confirm they have it; they confirm it came back. Every person gets a page and a track record. This is the feature no competitor has and the one that makes non-cataloguers open the app.
→ "Lent it? Know who has it. And when it's due back."
THE PAIN
"My dad's records are in a crate. I don't even know what's in there."
You don't need to be a collector to find out
No grading scale to learn, no account, no commitment. Photograph the crate, one sleeve at a time, and the app tells you what your father kept. The history starts with him.
→ "Find out what's in the crate. Keep what it meant."
THE PAIN
"Every collecting app turns into eBay within a week."
No selling, no prices, no server copy of your shelf
v1 has no market, no valuations, no listings. Your catalogue lives in your iCloud; photos leave the phone only if you ask for a lookup. Pay once. This isn't a limitation to apologise for — it's the headline for anyone who's been burned.
→ "It's a catalogue. It's not trying to sell your stuff."
THE PAIN
"It guessed the wrong pressing and wouldn't let me fix it."
Nothing is confirmed on your behalf
Every guess sits in a review queue marked unconfirmed until you agree. Real grading scales — CGC, Sheldon, Goldmine — not a free-text box. The hardcore collector's trust is won or lost on this one point, and most apps lose it on object three.
→ "It proposes. You decide. Every time."
Pain 2, proven: the ledger.
Pains 1 and 4: photo first, lookup toggle visible.
Pain 5: the review queue. Show doubt; it reads as honesty.
The pride line, proven: an object worth looking at.
03 · Message house
One roof, three pillars,
one floor
Every piece of copy — a post, a clip, a store screenshot, an email — makes one pillar's argument and points at the roof. Never all three at once; that's a feature list, and feature lists are what software does.
THE ROOF · SAID EVERYWHERE
{{ masterLine }}
PILLAR 1 · SPECIFICITY
Built for your hobby, not for "items"
Real fields, real grading scales, a type per hobby — and if yours isn't there, build it and it might ship.
Proof: the add form, the types list, a proposed type becoming official.
Reader: the hardcore.
PILLAR 2 · MEMORY
It remembers what happened
Lent, returned scratched, serviced, regraded, drink-by, open-it-this-week. History appends; nothing overwrites.
Proof: the lending ledger, the History tab, the clocks.
Reader: the hobbyist.
PILLAR 3 · OWNERSHIP
It's yours — the data and the app
No account, no server copy, photos stay home, CSV out anytime, pay once. Not a marketplace in disguise.
Proof: the privacy label, the lookup toggle, the price.
Reader: the owner, and everyone burned before.
THE FLOOR · WHY BELIEVE IT: made by one collector, in the open — the decisions log is public, the types are written with the communities, and the founder answers every message himself.
04 · Three readers, three doors
Same app, different
first sentence
READER
WHAT THEY FEAR · WHAT THEY WANT
THE HOOK · WHERE IT LANDS
THE HARDCORE
400+ objects
Fears being dumbed down, wrong data he can't fix, losing ten years of Discogs notes. Wants field-level control and an export he trusts.
"Here are the eleven fields I think describe a [record]. What did I get wrong?" — not a pitch, a schema question posted in his forum. He becomes a Founding Cataloguer; his corrected schema ships with his name in the release note. Channel: forums, Discord, Reddit. Never ads.
THE HOBBYIST
60–150, growing
Fears another app he'll abandon; looking like a nerd. Wants a shelf worth showing and to stop losing things to friends.
"Who did you lend it to?" — a 12-second clip: object leaves, row turns dashed, notification arrives, it comes back. Channel: Reels/TikTok, the shelf-reveal format, a friend's share link. This reader is where volume comes from.
THE OWNER
one inherited crate
Fears being scammed, being judged, a subscription trap. Wants to know what's there and what it meant, once.
"What's in your father's crate?" — the emotional door. Free tier is the product for him; he may never pay and he'll tell three people. Channel: App Store search ("inventory", "catalogue"), a share link from a collector friend, Google for "what are my dad's records worth".
05 · The letter
The founder's note,
ready to paste
The single most reusable asset. It goes on the website, in the first community post after the schema question, in the TestFlight invite, in the "About" screen, and as the reply when someone asks "so what is this". You are the guide, not the hero — the reader is the hero, and his collection is the story.
I collect records. Around three hundred, mostly seventies pressings, nothing that would impress you. For fifteen years I kept them in a spreadsheet, and for about twelve of those years the spreadsheet was wrong.
Two things finally broke me. I lent a first pressing to a friend and, two years later, neither of us could remember whether it had come back. And every app I tried to replace the spreadsheet with turned out to be a shop — it wanted a price on everything, and it wanted my shelf on its server.
So I built the thing I wanted. It's called CLCTN. You photograph an object and it tells you what it is; you confirm. It knows the grading scale for your hobby, not a generic one. It remembers who has what, and what happened to each thing over the years. And it lives in your iCloud, not mine — there's no account, and you pay once.
It's built with collectors: every type is written with the people who collect that thing, and if yours isn't there yet, you can build it and it might become the next one to ship.
If you own things on purpose, I'd like you to try it and tell me what I got wrong.
— Jérôme, one collector to another
Swap the numbers for your true ones; the only rule is that nothing in it is invented. Specific and slightly unflattering beats impressive every time — "nothing that would impress you" does more work than any adjective could. Placeholder name until you tell me yours.
06 · The mechanics
Nine techniques, each
with a reason it's honest
Modern growth tactics work on collectors exactly as well as on anyone — as long as every one of them is true. The moment a tactic requires a small lie, this audience leaves and posts about it. Each item below passes that test.
01 · FOUNDING PRICE LADDER
Scarcity that's real
€19.99 for the first 1,000 unlocks, then €24.99, then €29.99 — and the price you paid is yours forever. Show the counter on the website. Urgency without a fake timer: the price genuinely rises because the product genuinely improves.
02 · BUILD IN PUBLIC
The decisions log is the content
You have 35 numbered decisions with reasons. Post one a week — "why we cut valuation from v1", "why a wishlist is just an object you don't own yet". Collectors love reasoning. It also pre-answers every objection before it's raised.
03 · THE SCHEMA QUESTION
Community-led, not community-spammed
One post per hobby: the fields, and "what did I get wrong?" It's a contribution, not a launch. The people who answer in paragraphs are your first fifty users and they arrive already invested. Full recipe in the growth plan.
04 · FOUNDING CATALOGUERS
Fifty names, credited forever
The TestFlight cohort gets a badge in the app, their name in the type's release note, and the founding price locked. Status, not money. They will defend the app in threads you'll never see.
05 · PRODUCT LOOPS
Three ways the app invites the next user
Share link — one object, no account needed, ends on "keep yours too". Shared wishlist — "you own 3 of these" is irresistible. Type proposal — the proposer of a shipped type tells his whole community. Each loop ends on a shelf, not a signup form.
06 · TWELVE LAUNCHES A YEAR
One type a month = one launch a month
Each new type gets its own community post, clip, custom store page and release note. You never "launch" once and go quiet; there's always a hobby whose turn it is. Retro computers, wine and artwork are the next three, each with a ready-made story.
07 · THE SHELF REVEAL
A format people copy
A 10-second vertical clip: real shelf, cut to the rendered shelf scrolling, end card "Know what you own." Post yours; ask Founding Cataloguers to post theirs. Formats spread; ads don't. Prompts in the video playbook.
08 · REFER WITH THE PRICE, NOT CASH
"Give a friend your founding price"
After the ladder rises, an unlocked user can hand three friends the price he paid. Costs you nothing you wouldn't have discounted anyway, feels like a gift rather than a scheme, and the friend arrives via a person they trust.
09 · THE WAITLIST WITH A JOB
Five emails, each one useful
Not "we're excited!" — each email gives something: the vinyl schema PDF, the decision on valuation, a shelf-reveal, an invite to vote on the next type, then the TestFlight link. People who read five useful emails buy on day one.
07 · Copy bank
Lines to paste, and
words never to use
HEADLINES · WEBSITE, STORE, POSTERS
Know what you own.
Know what you own, and who has it.
The shelf, not the spreadsheet.
Your collection, finally worth looking at.
Built hobby by hobby, with the people who collect it.
It remembers, so you don't have to.
A catalogue. Not a shop.
Pay once. Own it. Like everything else you collect.
VIDEO HOOKS · FIRST TWO SECONDS, SPOKEN OR ON SCREEN
"Who did you lend it to?"
"I found my dad's records. Here's what was in the crate."
"Every collecting app becomes eBay. This one can't."
"Ten seconds per record. I timed it."
"This is my spreadsheet. This is what it should have been."
"The app said Near Mint. I said VG+. The app agreed."
"Three bottles hit their peak this month. My cellar told me."
"It's a 1985 machine. The app says don't power it on. It's right."
COMMUNITY POST OPENERS · NEVER A LINK IN THE FIRST POST
"I'm building a catalogue app and I'd rather get the vinyl fields right than fast. Here are the 11 I have. What's wrong?"
"Question for people who lend records: how do you keep track? Asking because I lost a first pressing this way."
"Decision I made and I'm not sure about: no prices anywhere in v1. Would that be a dealbreaker for you?"

WHAT THEY MEAN
YOU SAY
"Discogs already does this for free."
I've invested years there; don't make me start over.
"Keep Discogs — import it in one tap, grades intact. CLCTN is for the things Discogs won't do: who has it, what happened to it, and everything you collect that isn't a record."
"€30 for an app?"
I've been burned by subscriptions and abandonware.
"Once. Not a month, not a year. Less than one record, for the tool that looks after all of them. And fifty objects are free forever — decide after you've used it."
"Where does my data go?"
Is this another company building a database off my shelf?
"Your iCloud. There's no account and no copy on our side — we literally can't see your shelf. Photos leave the phone only when you switch on a lookup, and the switch is on the camera screen."
"My hobby isn't in the list."
You built this for other people.
"Then build it — the generic type takes any field, and the popular ones become official with your objects carried over. Three of our types started exactly that way."
"No valuation? Then what's the point?"
I want the number.
"Not yet, on purpose — the moment money is on the screen it becomes the app. It's coming, and it'll be optional. What you paid is already there, on each object, if you want to type it."
"What happens if you stop?"
Solo dev, small app, I've seen this end badly.
"Your data is in your iCloud and exports to CSV any day you like, with the type's schema attached. The app keeps working without a server because there isn't one. That's the honest answer, and it's also the design."

10 · For your designer friend
Three things I'd want
argued with
Q1 · THE MASTER LINE
"Know what you own" — promise, or scold?
It's chosen because it's short and true and implies a gap. The risk is that it reads as mild judgement to the owner persona, who already feels behind. Alternative is the pride line. My answer: keep it; "The shelf, not the spreadsheet" does the warmth in support.
Q2 · LEADING WITH "NOT A SHOP"
Is defining yourself against marketplaces a position or a complaint?
Pillar 3 leans on it hard and it's the line that gets the loudest agreement in forums. It's also the line that dates fastest if v2 adds selling. My answer: say "a catalogue first" rather than "never a shop", so v2 is a fulfilment rather than a betrayal.
Q3 · THE LETTER
Founder story on the front page, or one click behind it?
Founder-led sells to the first thousand and can look small to the ten-thousandth. My answer: front page until the founding ladder closes, then it moves to About — the price change is the natural moment.
