How Two Founders Made $100K in 90 Days From a Single TikTok Account

A few weeks ago, a tweet started circulating that looked too good to be true. A small AI app had cleared $100,000 in revenue in 90 days. The kicker: no paid ads, no PR agency, no investor Rolodex. Two founders, two laptops, and one TikTok account.

The app is Natural Write, an AI humanizer that takes machine-generated text and rewrites it to bypass AI detectors. The people behind it are Nikita, based in Serbia, and Yevgeniy (everyone calls him Yini), based in Poland. A third teammate, Alexander, handles the technical side. What makes their story worth studying isn’t the product — there are hundreds of AI humanizers on the market. It’s the TikTok marketing strategy they used to pull nine million views, a quarter million signups, and six figures of revenue from a standing start.

An Idea Born From a Growth-First Mindset

Most founders pick a problem and then hunt for a channel. Nikita and Yini did the opposite. They picked the channel first, then reverse-engineered the product.

“During our research we noticed that there are so many videos about humanizers,” Nikita explains. “I just thought, okay, we can do the same. It’s much easier to promote it on TikTok because it’s a hot topic. We decided two weeks, we make a product, start promoting it, and it worked out.”

That framing — viral proof first, code second — is the quiet thesis behind everything that came next. They weren’t trying to invent a category. They were trying to surf one.

The 7-Step TikTok Marketing Strategy That Moved $100K

When pushed to break down their playbook, the pair didn’t hedge. Their TikTok growth strategy is disciplined, almost boringly operational, and it’s the kind of thing anyone with a weekend and a plan can replicate.

Step 1. Niche research before a single line of code

Before they opened a code editor, they opened TikTok search. The goal: find hard proof that competitors existed and that their videos were actually going viral. TikTok Search and Creator Search Insights became the primary research tools — not Google, not SimilarWeb, not Ahrefs. If the niche didn’t already have viral videos, they weren’t going to build in it.

Step 2. Set up the account like an operator, not a hobbyist

This is where most people skip ahead and lose. If you’re not physically located in your target market, they insist you need a VPN, a fresh iPhone, a phone number from the target country, a new email, and a new Apple ID. The first account should be registered on that phone number. Why the paranoia? TikTok localizes the algorithm aggressively, and a mis-geotagged account will shadow-ban itself for weeks before you realize what happened.

Step 3. Warm up the algorithm — manually

Thirty to fifty minutes a day for three to five days before posting a thing. Watch videos in your niche. Like them. Comment on them. Follow creators. Search. The signal you’re sending to the TikTok algorithm is: this account cares about X. By the time you post your first video, the “For You” graph already knows where to send it.

Step 4. Recreate what already works

No original formats. Not yet. Take viral videos in your niche and make high-fidelity one-to-one copies — same hook, same pacing, same on-screen captions added inside the TikTok editor (they’re emphatic that native captions outperform pre-burned text). The rationale is brutal and correct: the algorithm has already validated that format. Your job is to ride it.

Step 5. One video per day, posted at the right hour

One. Not ten. The cadence isn’t about volume — it’s about consistency and signal. They post in the second half of the day, aligned with their target audience’s scroll time. Posting at 3 a.m. local is a rookie mistake.

Step 6. Innovate only after you’ve gone viral

Once videos start popping and you actually understand how the audience behaves, then you get to invent your own hooks and formats. Not before. The original experimentation is a reward for having earned algorithmic distribution, not an ante.

Step 7. Scale horizontally

More accounts. More creators. Once you’ve found what works on one account, the engine becomes a cloning exercise: new phone numbers, new emails, new VPN endpoints, new handles — the same playbook, running in parallel. This is where most solo founders start drowning in operational overhead and where a scheduling layer stops being a nice-to-have.

The Viral Videos That Actually Moved the Needle

Two videos carried most of the traffic. The first was a riff on a Jim Carrey comedy bit, reframed as “you have an essay to submit in five minutes” with Natural Write as the payoff. It took a couple of hours to shoot and pulled four million views. Nobody on the team expected it to hit.

The second was a dead-simple before/after: “here’s 100% AI-generated text → click → 100% human-written text.” The original version of this format, shot by another creator, had done about 150,000 views. Yini’s copy did 1.5 million. Same structure, better execution.

The lesson isn’t “be funny” or “be clever.” The lesson is that a viral format is a pattern. The pattern doesn’t care who runs it — it only cares that the cadence, the cuts, and the payoff land. If you can execute a format tighter than the original, you win.

The Numbers Behind the 90 Days

• Total TikTok views: ~9 million across all accounts
• Total visits to the site: ~300,000
• Signups: ~250,000
• Visit-to-signup conversion: ~80%
• Revenue: $100,000 ($41K month one, $32K month two, $27K month three)

The 80% visit-to-signup rate is the number that should stop you. It’s a direct function of the TikTok-to-landing-page match. When the video teaches the product — “paste text, click humanize, done” — the landing page is just the button. There’s no persuasion gap to cross. By the time a user clicks through, they’ve already been sold, on-device, in under 30 seconds.

A $70-a-Month Tech Stack

The infrastructure is almost comically lean. Next.js for the frontend, Postgres for data, Coolify for self-hosted deployments, NextAuth for auth, and Resend for transactional email. That’s it. Their server bill runs $35 a month. Resend is another $20. The VPN that keeps the TikTok accounts clean is $5 per month for five devices, and U.S. phone numbers cost them $5 per month per number.

Other than their own time, the total monthly burn to run an app doing six figures in 90-day revenue is on the order of $70. Most SaaS founders spend more on Notion and Figma.

Their Two Pieces of Advice

Nikita’s advice to his past self: “Start your TikTok journey by yourself. Find out what works, and only then start thinking about delegating or hiring other people.” In other words, don’t pay influencers before you understand the platform — they tried that first, and it flopped. No one cares about your product as much as you do, and no one will make the format-level judgment calls required to go viral until someone has actually done it in-house.

Yini’s advice is even blunter: “Don’t overcomplicate it. Skip inventing your own TikTok format. Just replicate what’s already going viral.” The founders who spend a month trying to craft a signature style are the founders who post a dozen zero-view videos and quit. The founders who copy ruthlessly for six weeks and innovate in week seven are the ones who hit a million.

Where the Playbook Breaks Down — And How to Fix It

Here’s the part the video skips. The seven-step playbook works beautifully on one account. By account three, you’re juggling multiple phones, multiple VPN contexts, and multiple posting calendars in different time zones. By account ten, the operational load is a full-time job. This is precisely where most founders who try to replicate the Natural Write model stall out.

The fix is to treat content operations the way engineers treat deploys: centralize the pipeline, automate the scheduling, and keep a single pane of glass over analytics. A dedicated TikTok scheduler — and more broadly, a social media scheduling tool that understands multi-account workflows — is the piece that turns the playbook from a side hustle into a repeatable engine.

With Postiz, for example, the seven steps map cleanly onto product features:

• One workspace, many accounts. Connect every TikTok account (plus Instagram, YouTube Shorts, LinkedIn, Reddit, Threads, and the rest) and schedule into all of them from a single calendar view. You stop losing track of which account is due to post today.
• AI captions and variations. Feed the same core concept into the built-in AI agent and have it spin platform-specific captions automatically. This matters once you’re cloning a viral format across five accounts and don’t want them flagged as duplicates.
• Cross-posting without the repost tax. A single piece of vertical video can fan out to TikTok, Reels, and Shorts in one click, scheduled at the right hour for each audience.
• Analytics that actually answer the question. Per-post and per-account engagement metrics, so you can see which format is carrying the network and which account is underperforming — before you burn a week on a losing variant.
• Automation hooks. Native API, MCP server, and integrations with n8n, Make, and Zapier let you wire content generation, approval, and scheduling into an end-to-end AI agents workflow — the same direction every serious content team is moving in 2026.

The point isn’t that tooling replaces the work. The Natural Write playbook still demands human taste: which format to copy, which hook to lift, which account to scale. What tooling replaces is the operational tax — the swivel-chair cost of logging into six apps at 7 p.m. every day to push one video. Killing that tax is the difference between one founder doing 9 million views in 90 days and a small team doing 90 million in a year.

The Takeaway

Natural Write isn’t a technical miracle. It’s a market miracle, and a distribution miracle. The underlying insight — pick the channel first, copy what already works, scale horizontally once it’s working — is the most replicable part of the story. The product is almost incidental. What’s transferable is the TikTok content strategy and the operational discipline to run it every single day for 90 days without breaking cadence.

If you’re sitting on an AI app, a SaaS, a physical product, or just an idea you haven’t validated yet — the cheapest, fastest validation in 2026 is still the same one Nikita and Yini used. Find the viral format. Copy it tighter than the original. Post once a day. Then build the machine that lets you do it across ten accounts without losing your weekends.
