I'm Rajat, I'm 22, and I Built an AI Agency Out of My College Bedroom

I've been writing code for six years. Started messing around with it in high school, kept going, and now I'm in my final year of Computer Science at NC State. Somewhere along the way, building things on a screen stopped being a hobby and became the thing I'm best at.

I also spend too much time on social media. But that turned out to be useful. I've watched thousands of ads, studied how brands sell, noticed what makes people stop scrolling. I know what good marketing looks like because I've consumed an absurd amount of it.

Quick note before the story — this blog is going to cover three things. The latest AI news broken down in plain English, no hype. Tips and tricks from what I've learned shipping real projects for real businesses, and from what I see working right now in the market. And a lot of content on how to actually use AI to make money — side hustles, charging more for what you already do, or automating the parts of your week that are eating your time.

For a long time, I wanted to combine those two things and start something. I didn't.

Why I Waited

The fear wasn't about the work. I knew I could build. I knew I could sell — I've never been scared to walk up to someone, pick up the phone, or cold call a business. Selling came naturally to me, and I figured if I could pair that with AI and automation, I'd have something real.

What scared me was posting. Putting my name and face on something publicly and having people I know see it. The thought of someone from class or back home watching me promote a business and thinking it was corny or that I was trying too hard. That embarrassment kept me on the sidelines for longer than I'd like to admit.

I kept finding reasons to wait. "I'll do it after this semester." "I need to learn one more framework." Meanwhile, I watched other people launch things that were worse than what I could build. At some point, that bothered me more than the fear of being judged did. I got over the posting thing by just doing it. The first few were uncomfortable. Then they weren't.

What Finally Made Me Start

I kept meeting small business owners who were getting wrecked by their web agencies. A restaurant paying $8,000 for a WordPress site that loaded in six seconds. A lawn care company spending $500 a month on "SEO services" that amounted to a monthly PDF report with no actual changes. A barbershop that paid a freelancer who ghosted them halfway through the project.

These weren't dumb people. They just didn't know what a website should cost, what the technology should look like, or what questions to ask. And the agencies and freelancers they hired had no incentive to educate them.

I started S4 AI Agency because I wanted to be the option I wished existed for those business owners. Custom websites built on modern technology, not recycled WordPress templates. AI tools that actually do something useful, not buzzwords on a sales page. Fair pricing from someone who'll explain what you're paying for and why.

What We Actually Do

We build custom websites using React, Vite, and Next.js. They load fast, they rank well on Google, and they're optimized for AI search engines like ChatGPT and Perplexity (that's called GEO, and most agencies haven't even heard of it yet).

We also build AI automations for businesses. Chatbots that handle customer questions. Lead capture systems that qualify prospects while you sleep. Workflow automations that replace the repetitive tasks eating up your week.

Everything is custom. We don't use Wix templates or page builders. If you work with us, you get a site that's actually yours, built for how people search in 2026, not 2019.

We're based in North Carolina and work primarily with local businesses in the Charlotte, Raleigh, and Triangle areas. Though we've taken on clients from outside the state too.

What This Blog Is For

I publish two to three times a week here. Some of it will be AI news broken down in plain English. I read a lot of research papers and product announcements so you don't have to. I'll tell you what actually matters for your business and skip everything that doesn't.

Some posts will be about web design and what separates a site that generates leads from one that just exists. I'll share real numbers, real case studies from our clients, and specific things you can do to improve your online presence without hiring anyone.

And some posts will be about building a business while still being in school, because that's my life right now, and I think other young people thinking about starting something might find it useful to hear what that actually looks like.

AI is moving faster than anything that's come before it. A model that was state-of-the-art three months ago is already obsolete. New capabilities, new tools, new ways to automate tasks that used to cost real money — every few weeks, the game changes. Most business owners don't have time to track it. That's what this blog is for. Subscribe on the blog page to get it straight to your inbox.

If You're a Business Owner Reading This

I don't have a decade of agency experience. I have six years of building things, a computer science education, and a genuine frustration with how the web industry treats small businesses.

If you want to talk about your website or about how AI could actually help your business (not in a vague "AI is the future" way, but in a "here's what it would do for you specifically" way), reach out through the contact page. I'll give you an honest assessment, and if we're not the right fit, I'll tell you that too.
