Pat WallsAll right, Gaurav, welcome to the channel. I'm pumped to have you on here. First, tell me who you are, what you built, and what's your story?

GauravHey, Pat, so good to be here. My name is Gaurav. I built Fastlane. We're an AI short-form marketing tool for solo builders. We do around 69k a month in recurring revenue just for our software product. We officially launched just over 2 months ago, and we scaled from around 16k ARR just from some paid beta users to over 1,000 paid users now and over a million ARR across the entire business. Today, I'm really excited to share more about everything we did to get here.

Pat WallsOkay, two things. First of all, you only launched it 2 months ago, and you're doing $69,000 a month in revenue, which is insane. So, congratulations on that. The second thing, you have a little secret, which I think is amazing, and it's one of the reasons why I wanted to bring you onto the channel. We're going to talk about it, but before we do, we got to understand, what's the business model, what's the business? And if you could pull up some of …

Gaurav… we thought the name sounded cool. And we said, "Okay, we're going to build an AI. You can do SEO, LLMO. You can engage with people on Reddit. You can make short-form content." Again, we're very early. We were really felt passionate about this problem. So, we thought, "Surely the best solution is just to do all of it in one." We spun up a few V1s, which we started in July. We shipped those in around August and kept shipping throughout September.

GauravAfter kind of interacting with customers, we realized the final product that we wanted to build was short-form content. So, we went all-in on the short-form content part. That development started around in October, and by the time we got to December, we had shipped the beta of this vertical solution to around 2,000-person wait list. After lots and lots of feedback and iteration, we officially launched what we know as Fastlane today publicly to the world on March 23rd.

Pat WallsKind of what you said there is you just wanted to get started, potentially solving that problem, uh, but you probably solved it a little bit too wide, and then the classic advice is to niche down. Let's switch topics a little bit and talk about what's the tech stack behind this nearly million-dollar SaaS in 2026?
