From $0 to $300K a year in 8 months, mostly alone with AI

Akshaya Dinesh's last startup took several years, millions of dollars in VC money and a team of very talented engineers to reach $300K a year. This time she got there in 8 months, mostly by herself with AI, and brought on a couple of people a few months in. Here is what she did, in the order she did it.

The step almost everyone skips

Most people who want to build an app start by building it. She did the opposite. Before writing a single line of code, she opened a TikTok account and an Instagram account and started posting videos about the app she was going to build.

"Before you even start building anything, start a TikTok and Instagram account and start posting founder-POV content talking about your app," she writes. "Tell your story, talk about features, practice UGC-style videos, and keep your account warm in your niche."

She built a small mockup of the one feature that mattered and put it in the videos. Then she watched what people did. Did they relate to it? Were they asking for the download link? Were they joining the waitlist? Her bar: "If you're able to consistently hit 10K+ views, you are onto something!"

Getting the videos right took her weeks of scrolling TikTok in her niche to learn what works there. She says you cannot hand that to someone else: you have to soak it up yourself.

That one step gave her two things before the app existed. Proof that people wanted it. And an audience already waiting on launch day.

Why she built it

She had done this before the hard way. At her previous startup it took several years, millions of dollars in VC funding and a team of very talented engineers to reach $300K a year. This time she wanted to know if the new way was real.

She gave three reasons for starting. She was curious whether the hype about vibe coding, building software by describing it to AI, was real or fake. She wanted to teach herself how to build an AI agent product from scratch: writing evals, picking models, building tools, managing context. And she had a problem herself that she genuinely cared about solving, for a group of people most apps had left alone.

She started building in the fall of last year. Eight months later the app was at $300K a year, run mostly by her plus AI, with a couple more people brought on a few months in.

She learned almost everything she knows about growing consumer apps from other creators on X, and wrote the post to pay it forward. Her goal for the reader is plain: "by the end of this post, you should have enough information to go launch your first app and make enough money to quit your full-time job."

Step 1: Picking the right idea

Her first warning is about time. "Now that AI has made it so easy to build an app, you should be spending as much time figuring the right things to build as you are actually building it."

The way she sees most people fail: they pick a random idea based on a problem they made up, spend months obsessing over details, and find out nobody wants it.

Her fix is to think like a normal customer. Spend time scrolling TikTok, Instagram and Reddit in your niche. If you don't watch short videos, look at search terms on Semrush and Google Trends, join niche online communities, look at popular YouTube videos. "Talk to literally anyone outside of tech for 5 seconds."

She chose health and wellness because she cared about it personally and had spent years in it as a customer. She also did interviews with other people who had the same problems she did. She wanted to build something they would love.

Then she checked the market with Astro, an App Store keyword research tool. She was looking for a balance: enough people already searching for an app like hers, but not so much competition that she could not get seen. That balance pays off later when you buy App Store search ads. In her space there was only one strong competitor, and they were spending money on ads on every platform. She thought their product sucked and that she could build something way more useful.

Once she had the problem, she picked the 1 or 2 killer features she could market. And she gives an easy formula for finding them: take a big successful app's features and aim them at a much smaller group of people. Her examples: Calm for manifesting and astrology. Duolingo for learning chess. Cal AI for women.

"Don't be afraid to copy what works," she writes. "They've done years of iteration to perfect their strategy."

Step 2: Content comes first

This is the step at the top of this page, and she puts it before building on purpose. Founder videos in her own voice. The story of why she was building it. Short demos of the mockup. An account kept warm in her niche. The signal she wanted was people asking for the link on their own, before there was anything to download.

Step 3: Vibe coding it

Before she built anything, she had a huge Figma board covered in screenshots of other popular apps: their onboarding screens, their paywalls, their main feature screens. She used tools like Mobbin for ideas. But she says nothing beats downloading every major competitor and using it yourself. She has 100+ random apps on her phone. She also used AppFigures to see which apps were growing fast in her niche.

Then a little planning: make sure you understand your user, their main problems, and the smallest version that solves them.

Then what she calls the fun part. She built the app in Cursor and Claude Code in a few weeks, back when coding models were not as good as they are now. Today, she says, this stage should take 1 to 2 weeks. "If you're spending longer than that, you're probably getting nerdsniped."

She did not worry about design or polish. The first version had three goals:

• A long onboarding. Many screens of questions before the paywall. "Long onboarding sounds counterintuitive, but for apps in most categories, having more screens in onboarding helps the user commit more to the app before seeing a paywall."
• A hard paywall. Pay to use it.
• 1 or 2 core features that work well.

She also put a review prompt at the end of onboarding, so the app would not get stuck with low reviews right after launch.

For subscriptions she used RevenueCat. For watching real people use the app, PostHog session recordings. Both cheap, both work well.

Getting through Apple's review took about 1 to 2 weeks the first time. She used Claude and ChatGPT to go back and forth on her app description, screenshots and screens to catch problems before submitting. Her advice: be patient, most apps get rejected on the first try.

It was not smooth all the way. In October the app was banned from the App Store for 2 weeks.

Step 4: Marketing, monitoring and iterating

Launch day was easy because of step 2. She went back to the followers who had been watching her videos and gave them the link to install the app.

Then she watched everything. She built a PostHog dashboard for the whole funnel: app install, onboarding questions, paywall conversion, app usage, and who kept coming back. She set up Sentry to catch errors. "Get addicted to watching session replays and fixing issues you find."

Only when the funnel did not leak much, compared with public benchmarks for apps like hers, did she go hard on marketing.

A content factory. She kept posting her own founder videos, and added creators. She hired a few college students through SideShift, helped them start new TikTok and Instagram accounts, warmed them up in her niche, and had them post 1 to 2 times a day from scripts she wrote. Her formula: find videos that already did well in the niche, and plug the app in quietly. A screenshot overlay, a quick feature demo, or just the app's name in the caption.

App Store search ads. The one channel she wishes she had started earlier. "If your app has any latent demand whatsoever, you absolutely need to be doing ASA." She calls setting it up "braindead simple." Target keywords in your niche, and your biggest competitors' names too. She used Claude to help tune the campaigns after launch.

What she held back on. Meta ads, Google ads, Reddit, SEO, YouTube, Facebook groups. Her view is that all of it is a distraction until you have cracked organic content first. Spending on paid ads too early burns your margins and keeps you from talking to your users directly. And once your organic videos work, you can reuse them as ads later.

Her last line: "The best time to start is now! It's not too late!"

The numbers

Recap

• She proved demand with videos before writing code.
• Her idea was a proven app made for a smaller group.
• She built it with AI in a few weeks: long onboarding, hard paywall, 1 or 2 features.
• She launched to her own audience, fixed the funnel, then scaled with student creators and App Store search ads.
• Result: $300K+ a year in 8 months, mostly alone.
