I made Fastlane, an AI tool that turns your app into viral short-form content (3,000+ users so far)

Hey everyone, I’m Gaurav

I built something called Fastlane (https://usefastlane.ai) and we recently crossed 3,000+ users, so thought I’d share it here

The idea came from a pretty simple frustration

Building apps has become insanely easy
Getting users is still ridiculously hard

I kept seeing founders ship genuinely great products… and then just struggle to get anyone to see them

Everyone says the same thing:
“I can build, but I don’t know how to market”

So I started thinking about what actually works right now, and it’s pretty obvious

Short-form content

TikTok, Reels, Shorts
That’s where attention is

But making content consistently is painful:
You don’t know what to post
You don’t know what’s trending
It takes forever to make anything
Most posts flop

So most people just avoid it altogether

So I built Fastlane

You enter your website, and it:

• understands your product
• looks at what’s trending in your niche
• generates ready-to-post videos (hooks, formats, scripts)

Then the UI is super simple:

Swipe right = post it
Swipe left = skip it

Basically like a Tinder for content

So instead of sitting there trying to “come up with ideas”, you’re just picking from stuff that already works

Some early results have been pretty crazy

One user went from $0 to $1,500 in a few weeks
and pulled in 250k+ views just from content generated inside Fastlane

We’ve also seen people go from never posting anything…
to posting daily across TikTok, IG and YouTube

Biggest thing I’ve learned building this:

Distribution is honestly more important than the product now
If no one sees what you built, it doesn’t matter how good it is

Still a lot we’re figuring out though, especially around new accounts getting low views (because they aren't warmed up) and making content more creative.

Would genuinely love feedback from other builders here, especially if you’ve struggled with marketing

Curious what’s actually worked for you guys to get users?
