Most crypto marketing budgets go entirely to channels that can be attributed. That is a reasonable instinct and it leaves one job unaddressed.
A project that exists only as a website has a permanence problem. Nothing about a landing page, however good, signals that you will still be here in two years. Out-of-home does that better than anything else available, and it does it to several audiences at once.
What the medium is actually for
A billboard is visibly expensive. Everyone who passes one knows, without thinking about it, that somebody committed real money and booked it months ahead. That inference is the product.
For a crypto project, it lands on three audiences simultaneously:
- Customers, who stop treating you as another unfamiliar name.
- Partners, who quietly take you more seriously in a first meeting.
- Journalists, who are reassured in a way they will never say out loud.
What it does not do is direct response. Nobody scans a QR code on a motorway. Treating OOH as a performance channel is how teams conclude it does not work, when really it was measured against a job it was never doing.
The Mumbai campaign
We ran billboard advertising in Mumbai for Ubuntu Tribe, whose product is tokenized gold.
The asset needed no explaining. Gold already carries meaning in India that no campaign could manufacture, and the audience understood the underlying thing immediately. The problem was different: making a digital version of something so physically familiar feel equally solid.
That is precisely the gap out-of-home closes. A billboard is a physical object in the same city as the person looking at it. For a product asking people to trust a digital claim on a physical asset, the medium and the message agreed with each other.
The campaign reached over 20 million people in physical traffic across the city. Just as usefully, it gave the press and creator activity running alongside it a name people had already seen — which changes how a headline reads.
Planning placements
The most common mistake is buying reach instead of buying relevance.
A citywide buy produces a large impression number and a diluted effect. What works is concentration: the same audience seeing the same board repeatedly on a route they take every day. Repetition against a narrow audience beats breadth against a wide one, almost always.
So the questions we start from are physical, not demographic. Where does this audience commute? Which business district do they work in? Is there a conference bringing them into one place for a week? Where do your existing users already cluster?
Creative that survives three seconds
Someone passing a board at speed gives you about three seconds and no second chance.
That constraint rules out most of what a marketing team wants to include. One idea. A concrete proposition rather than a feeling. A name that can be spelled afterwards, because search is where the response actually happens.
For crypto specifically, the temptation to lead with price, returns or urgency is strong and should be resisted — those are exactly the claims that will not clear a legal review and exactly the ones that make a serious audience suspicious.
Everything on the board goes through your legal team before it is printed. Production lead times are real, so that review has to be scheduled rather than discovered.
Running it with everything else
Out-of-home works considerably harder when it is not alone.
The sequence we use: press briefed before anything appears, boards live first so the name becomes familiar, coverage landing into that familiarity, and social staffed through the window to catch what the first two generate.
Someone who passed your board on Monday and reads about you on Wednesday has formed an impression. The same two touches a quarter apart produce two forgettable moments. The window is what makes the budget work.
What we report
Traffic and audience data per placement, the reach delivered, and what moved alongside it — branded search, direct traffic and social mentions in the campaign area during the flight.
We do not claim click attribution for a billboard, because the medium does not produce it. What it produces is recognition, and recognition is what makes every other channel convert better.
Common questions
Does billboard advertising work for crypto projects?
It works for a specific job: making a project that exists only as a website feel permanent and substantial. A billboard is visibly expensive and visibly committed to, and that signal reaches customers, partners and journalists at the same time. It is poor at direct response and excellent at establishing that you are real, which in crypto is often the harder problem. We ran a billboard campaign in Mumbai for Ubuntu Tribe around tokenized gold that reached over 20 million people in physical traffic.
How do you measure out-of-home advertising?
Through traffic and audience data for each placement, which estimates how many people pass it and how often, plus the lift you see in branded search, direct traffic and social mentions in the campaign area during the flight. OOH is not click-attributable and any agency claiming otherwise is overstating what the medium does. What we report is the reach the placements delivered and what moved alongside them.
Where should a crypto project run billboards?
Where your buyers physically are, which is usually narrower than a citywide buy. Financial districts, commuter corridors into business areas, airport routes during a major industry conference, and the neighbourhoods where your existing users already cluster. A smaller, well-placed buy consistently beats a larger scattered one, because the medium works through repetition against the same audience rather than one-off impressions.
What should a crypto billboard say?
One idea, in three seconds, with a name people can spell afterwards. The creative that works leads with a single concrete proposition rather than a brand sentiment, because sentiment only works for names people already know. Everything on the board has to clear your legal review before it is printed, and that review is slower than digital because production lead times are real.
How does Corum8 run OOH campaigns?
We plan placements against where your audience physically travels, produce the creative, handle the media buying and run press and social to the same dates so the pieces reinforce each other. We have run out-of-home for crypto, fintech and neobank clients, including a Mumbai billboard campaign for Ubuntu Tribe. Corum8 has delivered 1,100+ projects since 2016 with 95+ specialists.
