The ElevenLabs fake ad contest asks you to invent a product that does not exist, build an ad for it in ElevenCreative, and give it a jingle. Enter by November 1, 11:59pm PST. No real product is needed. The top prize pool is up to $100K, and it runs as ElevenCreative Competition Vol. 1 under the tag #TheWorldsCatchiestAd.
This is a video skill contest as much as a writing one. The script is the easy part. The hard part is a hook that survives the first two seconds, a voice track that sounds like a brand, and a jingle that loops in someone’s head after they scroll away. Below is a three step build you can run this week, plus where Creator OS fits once the ad is rendered and you want it in front of people.

What Is the ElevenLabs Fake Ad Contest?
It is a creative competition run by ElevenLabs through its ElevenCreative product, and you enter by making a commercial for a product you invented.
The brief is short and that is the point. There is no real product, no client, no brand guidelines, and no reason to be careful. You are being asked to make the kind of ad that would never survive a real marketing review, which is exactly what makes it fun to watch and fun to judge.
Kevin covered the contest on the KevBuildsApps YouTube channel, including the three step structure and the deadline. Watch that first if you want the brief in video form: the fake ad contest video. Then come back here for the build details.
What You Can Win: The $100K Prize and Judging
The headline number is up to $100K, framed as a prize pool rather than a single cheque.
The contest materials describe the prize as up to $100K, so plan for the possibility that the money is split across placements rather than handed to one winner. I am not going to invent a breakdown of first, second and third place, because the official page is the only place that should tell you that. Read it before you spend a weekend on an entry.
What the brief does tell you about judging is in the tagline: #TheWorldsCatchiestAd. Catchy is the criterion. That points at memory, not polish. A rough ad with a hook you repeat in the shower beats a beautifully graded ad you forget in ten seconds. Judge your own draft on one question: could a stranger hum it back to you an hour later?
How to Enter the ElevenCreative Competition in 3 Steps
Invent a product, build the ad in ElevenCreative, add a jingle. That is the whole entry.
- Invent a product that does not exist. Name it, give it one absurd promise, and decide who would buy it.
- Make the ad for it in ElevenCreative. Script, voice, shots, music, all in the tool.
- Give it a jingle you cannot stop humming. One line, one melody, repeated at the start and the end.
Everything below expands one of those three steps. The order matters. Most weak entries start at step two, open the editor, and hope an idea shows up. The winning entries start at step one with a product so specific it writes the ad for you.
Step 1: Invent a Product That Doesn’t Exist
Pick a product with a built in visual, because you have to show it working in a few seconds.
Bad fake products are abstract. “A happiness app” gives your editor nothing to render. Good fake products are physical, slightly ridiculous, and instantly understandable. A pillow that cools your head to exactly 19 degrees. Gloves that let you type on a phone in the shower. A fridge that argues with you about leftovers.
Write three things down before you open any tool:
- The name. Two words, easy to say out loud, no spelling needed.
- The one promise. The single benefit, stated as a number or a time if possible. “Cold in 40 seconds.”
- The target buyer. One person, not a demographic. “The guy who eats cereal standing up at 11pm.”
Then write the line you want people to repeat. That line becomes your jingle lyric later, so keep it to six words or fewer. If you cannot write the repeatable line, the product is not sharp enough yet. Go back and make it smaller and weirder.
Step 2: Build the Fake Ad in ElevenCreative
Build a 15 to 30 second spot, because a short ad forces the hook and the jingle into the same few seconds.
Use a fixed structure so the edit goes fast. Four beats:
| Beat | Seconds | What happens |
|---|---|---|
| Hook | 0 to 3 | The problem in one shot, no logo, no intro |
| Reveal | 3 to 8 | Product appears, name spoken clearly |
| Proof | 8 to 18 | It working, ideally with an absurd result |
| Jingle | 18 to 25 | The repeatable line, sung, then the fake logo |
Record the voice first, then cut picture to it. Ad voice sets the pace and you will fight it if you cut the other way around. Use one voice across the whole spot, even the absurd claim, because a flat confident read of a ridiculous line is the joke. If the voice wavers or winks, the ad gets less funny.
Keep the on screen text to the product name and the promise. Nothing else. Vertical framing if you plan to post it to short form platforms, and remember that most people watch muted first, so the promise needs to be readable on its own.
Step 3: Add a Jingle People Can’t Stop Humming
Three notes, one line, two appearances. That is a jingle, and more than that is a song nobody remembers.
The most common mistake is writing a full 30 second music bed and calling it a jingle. A jingle is a hook. Hum something while walking to the kitchen. If you can still hum it at the fridge, it works. If you need the track playing to remember it, it does not.
Practical rules that hold up:
- Use the product name inside the melody, not just in the voiceover.
- Repeat the same phrase at the open and close so it bookends the ad.
- Keep the sung line under six words and under four seconds.
- Leave half a second of silence after it. The silence is what makes it land.
Then test it on a person. Play the ad once, wait five minutes, ask them to hum anything from it. Their attempt tells you more than any amount of mixing.
Fake Ad Ideas That Fit the ElevenCreative Brief
Steal a pattern, not a product. Each of these maps to a different comedic engine, so pick the one you can shoot fastest.
| Pattern | Fake product | Why it works |
|---|---|---|
| Absurd upgrade | Self cooling cereal bowl | Everyday object, impossible feature |
| Wrong audience | Noise cancelling headphones for one specific loud neighbour | Specificity is the joke |
| Number promise | Pillow that hits 19 degrees in 40 seconds | Measurable claim invites a demo shot |
| Anti product | A phone that only opens on Sundays | Contrarian premise, instant hook |
| Luxury nonsense | Artisanal ice, hand carved, $40 | Straight faced delivery sells it |
Pick one, then write the jingle before the script. The lyric will tell you which shots you need, and you will cut your shot list in half. If you get stuck on the edit itself, the tutorial on making high motion short form reels covers pacing and cut density that suits a 20 second ad.
ElevenLabs Fake Ad Contest Deadline and Rules Explained
The deadline is November 1 at 11:59pm PST, and the entry link and full rule set live on the official contest page.
The contest is described as ElevenCreative Competition Vol. 1 and carries the tag #TheWorldsCatchiestAd. Vol. 1 tells you something useful: treat this as the first round of a series and build a workflow you can reuse, not a one off. The brief is clear that no real product is needed, which removes the usual excuse for not entering.
On rules that are not in the video, go to the official page rather than a summary. Prize split, eligibility, entry format and how the work is submitted are the details that disqualify people who only read a tweet about it. Download your final file, keep the project, and submit early enough that a failed upload is not fatal.
FAQ: ElevenLabs Fake Ad Contest
What is the ElevenLabs fake ad contest?
It is ElevenCreative Competition Vol. 1, a creative contest where you invent a product that does not exist and make a commercial for it. The brief asks for three things: a made up product, an ad built in ElevenCreative, and a jingle. Entries carry the tag #TheWorldsCatchiestAd.
When is the ElevenLabs fake ad contest deadline?
Entries close November 1 at 11:59pm PST. That is the date and time given in the contest brief. Check the official contest page for any timezone conversion you need and for the live status of the deadline before you plan your last edit.
Can I enter the ElevenCreative competition without a real product?
Yes. A real product is not required, and inventing one is the first of the three steps. That is the point of the format: you are free to make the most ridiculous product you can describe in one line, then build the ad around it.
How is the $100K ElevenLabs contest judged?
The contest frames the top prize pool as up to $100K and the tagline points at catchiness, so expect memory and repeatability to matter. The full judging breakdown and the prize split belong on the official page, not in a blog summary. Read that page before you build.
Do I need video editing skills to make a fake ad in ElevenCreative?
You need less editing skill than you think, because a 20 second ad has about six shots. What you do need is a hook in the first three seconds and a sung line under four seconds. If you can write a repeatable line and cut to a voice track, you can enter.
Get started
Make the ad first, then think about where it goes. Once it is rendered, the ad is also a post, and a post can be tested. Creator OS publishes to Instagram, TikTok, YouTube, X, Facebook, LinkedIn, Threads, Reddit, Discord, Slack and WhatsApp, plus Skool, from the web app, the iOS app, the REST API, the CLI and a hosted MCP server, so an AI agent can schedule the fake ad, read the engagement numbers and reply to the comments it earns.
