Rasty Turek, a first-time iOS developer, says his encrypted-storage app Voltaire went from $66 in its first month to roughly $2,000–$3,000 a day within about six months — reaching a $41,000 month — without ad spend, a TikTok moment, or App Store ranking muscle. Speaking on Starter Story, Turek credits an automated pipeline that queries Google Keyword Planner each morning, targets keywords where his site gets impressions but no clicks, and publishes one high-quality guide per day: Google indexes each one in three to four days, internal links from existing traffic reinforce them, and about 10% of the resulting web visitors download the app. Just 5.47% of day-one downloaders pay, but conversion climbs for roughly two months, and a $399.99 lifetime tier drives “north of 80%” of revenue. The thesis for investors: in a category dominated by 15-year-old incumbents that ignore the open web, an AI-native content operation plus a privacy product that even the FBI cannot crack can compound quietly. Turek estimates 99% of the remaining work is a Claude agent waking up each morning. The open question is whether this is a repeatable method or a fit between one niche and one neglected channel.
Key Elements
Voltaire, an encrypted-storage app for the iPhone, earned $66 in its first month. Six months later it was bringing in roughly $2,000 to $3,000 a day, the kind of curve that usually comes with a Super Bowl ad or a viral TikTok. Rasty Turek, the app’s first-time iOS developer, did it with a daily AI-generated blog post.
That is not a typo, and it is the most interesting business story in consumer software right now. Speaking on Starter Story with hosts Pat Walls and Gus, Turek laid out a growth machine that runs almost entirely without him: an open-source command-line library he calls Gum, layered over Google’s services, queries Google Keyword Planner every morning, finds keywords where his site appears in search results but gets no clicks, and generates a guide aimed at that gap. He publishes about one a day. Google registers each new page in three to four days. Internal links from pages that already get traffic push the new ones up. And every morning, he says, about 99% of what remains to be done is Claude waking up and running the loop.
“I literally haven’t written a single line, either of code or the text on the web,” Turek said.
The result is the exact opposite of the playbook most app founders have been handed. Instead of fighting for App Store keyword rankings against incumbents that have been there for 15 years, Turek went around them — to the open web, where those same competitors never bothered to compete.
A familiar product with an unfamiliar moat
Voltaire is, in Turek’s own framing, an encrypted Dropbox. Files and photos are encrypted on the device. There are no servers and no shared keys, so neither Turek, nor Apple, nor anyone else can recover what is inside. Users open a vault by drawing a pattern, and the app is designed so that roughly 52 billion possible vaults exist — and so that it cannot tell how much data a vault holds, or whether it holds anything at all.
He built it for himself: a place to keep crypto wallet keys, photos of IDs, and birth certificates close to the device but still accessible. He planned to release it free and added a price the day before launch — mainly, by his account, to cut down on support requests. The app was his first iOS project, written in Swift with UIKit and using native iCloud features, and took about three weeks.
The clearest demonstration of what that design actually means came on a Friday, when an FBI agent called Turek asking for help opening a vault belonging to a person under investigation.
“The app is built such way that I can’t tell if the person ever had anything in there. And so the agent was pretty upset about it, but that’s what the app does,” he said. That inability to help is not a bug. It is the entire product.
The pricing curve that breaks every app rule
Monetization is where Voltaire departs most sharply from the standard subscription-app playbook. Most trendy apps have to convert a user on day one or never will. Voltaire has its lowest conversion on day one and its highest around day 60.
“My download to paid is only 5.47 on day one but day 35 it actually grows,” Turek said.
| Metric | Value (per Turek) |
|---|---|
| First month revenue | $66 |
| Recent monthly revenue | $41,000 |
| Current daily revenue | ~$2,000–$3,000, slowly rising |
| Total downloads | 60,000+ |
| Day-one download-to-paid | 5.47% |
| Website-visitor-to-download | ~10% |
| Lifetime purchase share of purchases | ~60% |
| Lifetime share of revenue | “North of 80%” |
| Weekly price | $19.99 |
| Annual price | $199.99 |
| Lifetime price | $399.99 |
The lifetime tier is the engine. Buyers who pay once for $399.99 account for roughly 60% of purchases and more than 80% of revenue, Turek said. That has a strange side effect: his monthly recurring revenue looks unimpressive in App Store analytics even as actual revenue climbs, because lifetime purchases do not roll up into the subscription number. He also flagged a data anomaly — a large download spike attributed to Apple Search that did not correlate with any revenue.
The sensible read is that this is a trust product. Nobody hands over their birth certificate and crypto keys to an app they installed 90 seconds ago. They do it after weeks of having it on their phone, watching it work, and deciding it is not going to lose their data. The 5.47% day-one number is not slow conversion. It is the front edge of a two-month decision.
Where the traffic actually comes from
The growth engine is web SEO, and it is worth looking at how mechanical it is. The pipeline does not chase big-volume search terms. It looks for the opposite: keywords where Voltaire already shows up somewhere deep in the results, gets seen but not clicked, and is therefore one good page away from real traffic. Turek’s example was a keyword where the site logged 16,000 impressions and zero clicks because it ranked around position 50.
The fix is a purpose-built guide, published, then wired back into the site with internal links from pages that already draw visitors. Google indexes it in three to four days. Then the loop runs again.
The restraint is the strategy. Turek is not flooding the web with machine-written articles, which is what almost everyone else does with an AI pipeline.
“Google likes the fact that there’s like not a lot of content coming, but the content is like high quality,” he said. “Like I make sure that the content is not such like vomit words.”
That is a notable bet in late 2026. Google’s tolerance for agent-generated content at one post per day is an assumption baked into the business, and it could change. But so far the arithmetic holds: about 10% of the web visitors Turek’s guides pull in go on to download the app — roughly double his day-one in-app purchase rate.
The gap is 15 years wide
Turek’s competitive logic is refreshingly unsentimental. The encrypted-storage category is full of apps that are 15 years old or more, with millions of downloads and Apple’s ranking favor behind them. He cannot beat them inside the App Store.
“Most of the apps in this area are 15 years or older… they completely ignore [SEO] because they don’t have to, they can have money and they just don’t care enough,” he said.
That is the wedge. The incumbents are not dumb; they simply have no reason to care about a channel that never mattered to them. A newcomer with an AI agent and a keyword list does.
A thin stack, on purpose
The business runs on almost nothing. The app is native Swift and UIKit. Codex and Claude handle development and content, with some local models for personal use. PostHog, which is free, handles measurement. That is roughly it.
Turek frames the low traffic and modest user base as an advantage rather than a limitation: there is little to measure and little to break, and the app keeps working as long as Apple’s infrastructure does. The privacy-first design also caps analytics — a trade he accepts willingly, since the product’s entire promise is that nobody, including its maker, can see what is inside.
There is a tension worth naming here. Walls later pointed out that Turek cannot fully see where his growth is coming from precisely because the product’s positioning discourages detailed tracking. That blind spot may matter more in the next phase than it does today.
The founder’s path supplied the domain, not the playbook
Turek’s résumé looks nothing like a consumer app founder’s, and he says so. He grew up in a 700-person village in Slovakia, moved to Boston after high school to work for a security company, and went to Google when that company was acquired. He worked on the Gmail team, then founded a security startup, then an entertainment company acquired by Amazon whose technology is still in use. His last venture-scale company was Pex, a copyright-as-a-service business focused mainly on music, sold in 2025.
None of that prepared him to build a consumer iOS app, he said plainly — his experience is B2B and enterprise. Which is precisely the point of his advice to other founders.
“I have at least two dozen projects that are somewhere in me ready but they’re not out there and as long as they are not out there they don’t exist,” he said.
His standard for execution is deliberately unglamorous: put one foot in front of the other, be slightly better each day, and stop overthinking. It is not a growth hack. It is a discipline, and it is the least copyable thing in this story.
What the hosts think comes next
In the post-interview debrief, Walls and Gus compared Turek to a previously interviewed founder, Mike Hill of Seven SaaS, for the same plainspoken “simple but not easy” approach — and contrasted him with the typical Starter Story guest who rides TikTok virality. Turek reads, they said, like an older founder with incremental discipline rather than an appetite for the latest hack.
Walls argued that SEO works here specifically because the niche is narrow: a privacy-focused encryption app will never draw a million daily visitors, and it does not need to. He also predicted that traffic will increasingly arrive through word-of-mouth, recommendations, and answers from AI models rather than search alone.
“I think the app will increasingly be surfaced in LLMs and AI search overviews,” Walls said, driving more attention and revenue — though he acknowledged Turek cannot measure that properly, because the privacy positioning discourages analytics. At over $40,000 a month and growing linearly, Walls said, the app is on track to become a million-dollar-a-year business. He wants Turek back in six months to see whether compounding content and growing AI visibility accelerate it.
What to watch
The open question is whether this is a repeatable method or a fit between one niche and one neglected channel. The pipeline depends on a category where incumbents ignore the web and on Google continuing to tolerate agent-generated content at one post per day — both could change, and neither is under Turek’s control. The late-peaking conversion curve adds a second wrinkle: revenue lags downloads by roughly two months, which makes current download trends, not current revenue, the leading indicator for whether the $41,000 month becomes a $1 million year.
For investors, the broader lesson is where the leverage sits. The IMF’s Kristalina Georgieva said this month that AI spending is keeping the world economy growing at around 3%, and Federal Reserve governor Christopher Waller argued the productivity gains from AI will take years to show up in the data. Voltaire is a small, early data point in that argument: a one-person operation using agents for both software and distribution, in a category where the incumbents have everything except the will to compete on the open web. Wall Street spent this week selling AI stocks on doubts about returns on all that capital expenditure. The most interesting returns may not be in the data centers at all — they may be in a $399.99 lifetime purchase from a stranger who trusted an app enough, after 60 days, to hand it everything.
Turek’s own framing is the claim most worth testing: he knew nothing about this space, and if he could learn it, anyone can. The next founder who tries the same playbook will tell us whether that is true.
