We invented a company, faked a product, and launched.
700,000 people watched it, and we went viral. Here’s the exact playbook.
Wednesday morning, we launched Sliceline.ai, a startup with a slick website, a product demo, and a fresh round of funding from a fictitious VC, Atomik.vc.

None of it was real.
Not the company. Not the raise. Not the VC.
By the end of the day, the launch video had 700,000+ views, and our DMs were full of people congratulating us on the round.
(Quick context: We've been in the launch game since day one, with 117M+ views across launches in the last three months alone.)
The whole point of this experiment was to prove a thesis: concept virality and personal networks beat influencer networks.
So, we capped ourselves on purpose: limited influencer spend, with everything else riding on the creative.

The Concept: Ridiculous, but Real Enough to Believe
We built Sliceline as a love letter to HBO's Silicon Valley: take something absurd, play it completely straight, and apply our Launch Playbook to see how far it could travel.
HBO's Silicon Valley Title Screen
In the TV show, Sliceline is a pizza delivery startup that uses smart "algorithms" to get you fresh, warm pizza quickly. We decided to give it a 2026 spin and sprinkle some AI into the mix.
Sliceline.ai would connect to your company's comms tools, and track team morale in real time. When your H.A.M.S score (Hunger Adjusts Morale Score) drops, it auto-dispatches a pizza to fix the mood. All powered by our in-house model, PIE-1.
Ridiculous? Maybe...
But, DoorDash actually shipped a CLI about an hour after we posted. So, we might actually build this thing. Who knows?

The first step was to make everything look real, well… real enough.
We one-shotted two websites (sliceline.ai and atomik.vc) using a tool called Hyperagent, connected it to our Github, and pushed to production with Vercel.
We were now ready to launch!
Hyperagent is pushing the vibecoded website to GitHub and highlighting which parts of the site need to be fixed to work in production.
The Creative: Engineered to Be Watched, Not Skipped
Virality Matrix
MrBeast boils virality down to two questions the algorithm is really asking:
A) Did people click?
B) Did they watch?
Everything else is downstream.
The click is your click-through rate. On X, it's the copy and the opening premise of the post that spark curiosity and signal that there's something worth surfacing.
But MrBeast treats the click as a promise, not a trick.
The copy sets an expectation, and the video has to deliver on it.
The watch is your average view duration (AVD). It tells the algorithm that the video kept its promise and deserves a bigger push.
Here's the catch with launch videos: either your product is novel enough to spread on its own, or your video is.
The hard truth is that most AI companies aren't differentiated enough to carry a launch on the idea alone. The originality has to come from the packaging.
How we click-baited on X
"We’ve raised $6M to turn sad employees into happy ones. One pizza at a time. Led by Atomik.vc.
We kept the X post copy extremely short and sharp, just enough to earn the click into the video.
In this case, we leaned into the absurdity: raising $6M to deliver pizza with AI sounds ridiculous, and people couldn't scroll past without figuring out what was going on.
But here's the part everyone underrates. The trick the industry never says out loud:
1M impressions does not mean 1M people watched your video.
A post with a million impressions usually lands somewhere between 10K and 100K actual video views.
That's a 10x range, and your copy decides where you fall in it.
Nail the copy and everything downstream multiplies: virality, profile visits, site clicks, signups, and the conversations that turn into revenue.
Tactics to Driving Retention
Retention is everything. It's the percentage of your video that the average person watches before they scroll.
Like YouTube and Instagram, X rewards content that keeps people on the platform for longer.
Here's how you win the retention game:
**Know where you're posting
**X has been TikTokified. Unfortunate, but true. It's now a short-form video feed, scrolled with the same restless thumb as TikTok. The editing that wins there wins here.
**Never let the motion die
**Keep the energy high. Not just in the hook, but all the way through. The second the energy drops, the graph drops with it.
The energy comes through both the speaker and the edit. In our Sliceline.ai video, we made a cut every 3.83 seconds. A shot that sits still is a shot people scroll past.
Your brain is drawn to movement. Every cut and zoom re-engages it and pulls attention back. A static frame does nothing. A flat UI screenshot under a voiceover is death.
Virality Orchestration: The Science behind coordinating influencers
Influencers vs Personal Networks
Most launches are orchestrated: pay a cohort of influencers to quote post and comment.
This does two things: it pushes the post into a lot of feeds, and it signals to X that the post has momentum, so the algorithm starts serving it to your target audience.
But there's a trap.
If you don't have enough real engagement, you'll never escape the influencer echo chamber.
You can rack up millions of views that go absolutely nowhere.
That's why the idea itself has to be genuinely interesting. Influencers can light the match, but they can't fake the fire.
And here's what most people miss by over-indexing on QT and influencer amplification:
X's algorithm is open-source. The single biggest virality flag is comments and replies, especially replies from the original poster. X wants a conversation.
https://x.com/SOLitudeGains/status/2013716131966484643
I made sure to reply to every comment as it came in during the first few hours of the launch. Don't drop the ball on the things you CAN control.
Here's the secret sauce behind our launches: once we have a great video, copy, and creative, we over-index on personal networks before influencers.
We built an internal tool that scrapes our personal networks and tells us exactly who we should reach out to for each launch.
We also built virality.studio, which tracks post performance minute by minute and separates the impact of personal network engagement from influencer engagement, so we know exactly what's moving the needle.
Personal networks are where the alpha is. Everyone has access to influencers, but not everyone has access to your sphere of influence. If you do this right, you can 100x the virality of your launch.
For Sliceline.ai, we reached out to our friends and brought them into the joke.

More is More
Quote-tweeting yourself sometimes feels like giving yourself a personal medal, but it increases your reach drastically.
Throughout the campaign, we quote-posted our original content with new, fun content to drive even more engagement.
Here’s an example of us assembling our Pizza boxes.

To really double down, allocate some of your influencer spend to the best-performing quote posts of the main post.
Have influencers, your personal network, and your own account engage with those posts too. That expands your surface area instead of piling everything onto one tweet.
Take the Launch Into the Real World
With more spend, we'd have pushed this launch beyond X and into the real world:
- Pizza boxes: Put merch inside real pizza boxes and hand-deliver them to the hottest companies in the Bay. If even 1 in 5 posted, we'd dominate X with content we didn't have to create. You can't pay for mindshare like that.
- A Sliceline pizza party: Host a Luma event a few hours after launch. The in-person moment creates another wave of organic posts and gets more people invested in the launch.
The Result
700,000+ views and counting, despite OpenAI, DoorDash, and Pocket launching the same day.
All for a company that doesn't exist.
The Takeaway
Launch videos used to be the edge. Now everyone's making them. The next edge is creating something genuinely unique and bringing it into the real world.
We just handed you the entire playbook.
