How My App Made $100K On Launch Day
Who are you and what business did you start?
Hey! I'm Gaurav, co-founder of Fastlane. We're an AI short-form content engine, where you can remix viral videos into content for your product in seconds and post straight to TikTok, Instagram and YouTube.
Our primary customers are solopreneurs, indie hackers & solo developers. Broadly, they are simply cool people building cool stuff.
We're the only tool on the market to create 1000s of shortform content for your business, which you can swipe through like Tinder to approve and post. We hit #3 on Product Hunt too!
We launched last week and are at over AUD $120,000 ARR :)

How do you come up with the idea for Fastlane?
We came up with Fastlane because we were builders ourselves, previously running 6–7 figure ecommerce brands and SaaS products, and felt firsthand how slow and painful content creation was.
After studying what consistently worked, we realised there had to be a faster way, remixing proven, trending content instead of starting from scratch. The “aha” moment was seeing how repeatable viral formats actually are. Unlike past ideas, this directly solved our own problem. We validated it by building a waitlist, generating strong demand, and running two betas, iterating quickly based on user feedback to maximise real value.
How did you build the initial version of Fastlane?
The founders of Fastlane built their AI short-form content engine by leveraging their experience in running successful ecommerce brands and SaaS products. They focused on creating a tool that remixes viral videos into content for easy posting on platforms like TikTok, Instagram, and YouTube. The development process involved studying viral formats and trends, validating the idea through user feedback, and iterating quickly to maximize real value. They launched the product leveraging their personal brand and Product Hunt, achieving strong initial traction and hitting #3 Product of the Day. Their growth strategy relied on using the product as a distribution engine, posting high volumes of content on various platforms like TikTok, Instagram Reels, and YouTube Shorts to reach their target audience effectively. Their key lesson learned was to focus on providing real customer value over hype, staying focused on solving one real problem, and moving quickly on feedback to iterate and improve the product.
How did you launch Fastlane and get initial traction?
We launched Fastlane by leveraging distribution we already had. I’d been building my personal brand on X (@gauravsbuilding), so our launch post there reached 210k+ views. We paired that with a LinkedIn launch and a Product Hunt drop, where we hit #3 Product of the Day.
The response was strong, people immediately tried the product and were shocked to try the platform and then hitting thousands of views for their product within minutes.
It took a few months to make our first dollar as we focused on building, but our first sale came from a beta user who paid just to keep access. It reinforced that real value drives demand.
What was the growth strategy for Fastlane and how did you scale?
We’ve grown Fastlane primarily by using the product itself as our core distribution engine. Since it’s built to generate and scale short-form content, our main strategy has been high-volume posting across TikTok, Instagram Reels, and YouTube Shorts, combined with audience building on X through my personal brand.
A real example is our internal growth loop: we go into Fastlane, generate content tailored to our niche, and post 100+ videos per week to TikTok, Instagram and YouTube simply by swiping right and scheduling. This allows us to consistently show up in front of our target audience while they’re already scrolling. Instead of chasing users, we let the algorithm bring them to us.
This works because of how modern discovery algorithms function. Platforms like TikTok are heavily incentivised to keep users engaged, and their organic algorithm now behaves very similarly to paid ads. They already know exactly who is interested in a given niche, and their job is to surface the most engaging content to those users. If your content aligns, you get distribution at scale without paying for it.
The key lesson is to lean into volume and iteration. You don’t need every video to be perfect, you need enough shots on goal to find what works. For aspiring founders, I’d strongly recommend doubling down on short-form content. It may feel uncomfortable to put yourself out there, but that barrier is quickly disappearing. With AI, you no longer need to film yourself, you can still compete and win purely through smart, consistent content. Good luck!
What were the biggest lessons learned from building Fastlane?
The hardest part was filtering out noise. There are endless flashy AI tools and trends, and it’s easy to get distracted. Staying confident in a focused, vertical approach to solving one real problem, content distribution, was difficult early on.
Our best decision was prioritising real customer value over hype and moving quickly on feedback. Speed of decision-making became a key advantage.
Timing also helped, short-form content and AI are both exploding.
A big lesson is that clarity beats complexity. Many founders overbuild or chase trends. Instead, move fast, stay focused, and double down on what actually works for your users.
