How creators are turning audiences into subscription businesses

Key Takeaways:
  • Proko has 4.38 million YouTube subscribers, built on free drawing lessons Stan Prokopenko started publishing in 2012
  • Forbes reported in May 2021 that more than 80,000 of his then-2.2 million subscribers were paying for premium instruction on proko.com
  • Proko ships four software tools, including Skelly at $6.99 once and Zolly free with $4.99 model packs
  • Every course page carries the same FAQ line: "It's not a subscription."
  • Drawing is a daily practice. The products his students open daily are the cheapest things he sells
Stan Prokopenko has done the hard half twice. He built an audience of 4.38 million people around a skill that takes years to learn, and then he built software instead of only selling videos about it. Four tools, two of them shipped to the App Store and Google Play under Proko LLC. Then he priced the software like it was 2015 shareware, and the arithmetic has been quietly working against him ever since. Stain Fix by Kristen Donathan

Stan Prokopenko is a San Diego artist and the founder of Proko, an online art school whose YouTube channel has 4.38 million subscribers and teaches drawing, anatomy, and figure construction. He was born in Odessa, Ukraine, came to the United States at six, and started evening classes at Watts Atelier as a high school junior. He studied there five years and taught there five more, according to his Tubefilter interview. The origin is smaller than most people assume. He launched a website in 2009 with written and illustrated lessons and earned almost nothing from the ads on it. When he moved to video in 2012, his ad revenue went from $40 a month to $450 a month. Four months in, he pointed that audience at a sales page and started selling DVDs. By giving the lessons away first and selling the structure second, in that order, for fourteen years. The DVDs became courses. The courses became a business with staff. By 2019 Proko had seven full-time employees, an intern, and roughly ten freelancers, plus six full-time web developers building what Prokopenko then described as a social online art school. By May 2021, Forbes reported that he had 2.2 million subscribers, more than 80,000 of whom paid for premium video instruction, and that he had spent over $1 million in four years building the platform and bought a studio facility in San Diego. On Mixergy that same year he described it as a $1.8 million business. In May 2023, Marvel partnered with Proko to publish a full comics curriculum on his platform. That is a real company. It is the same arc Justin Sandercoe ran with free guitar lessons and Thomas Frank ran with Notion templates: give the teaching away, sell the structure. Proko ships four tools: Skelly, a poseable anatomy model for iOS and Android; Zolly, a perspective drawing app for iOS, Android, and Windows; a web Timer for timed drawing sessions from photo reference; and a web Value Study tool that reduces any image to limited values. All four are listed on the Proko apps page.

Look at what those four things have in common. Every one of them is something an artist uses while drawing, not before or after. A timer that runs a life-drawing session. A skeleton you pose to check a shoulder. A value study of the painting you are copying. These are not lead magnets. They are the working surface of a daily practice. Here is how they are priced.

Because Proko treats software as an accessory to the courses instead of a product in its own right. The pricing tells you exactly where the attention went. Portrait Drawing Fundamentals is $65. Total Guide to Figure Drawing is $79. Figure Drawing Fundamentals is $150. Drawing Basics is $159. Anatomy of the Human Body runs $477 across three parts, or $434.07 bundled. Nobody is underpricing anything there. A $477 anatomy course is a serious product at a serious number. And every course page answers the same question the same way: "No, it's a one-time payment and you have access to the videos forever. You are essentially purchasing a product. It's not a subscription." Proko's own support staff confirmed it in the community forum. There is no membership tier. Prokopenko said it plainly on Mixergy: "It's not a membership. It's you, you still go on and you can still buy individual courses." Skelly went on the App Store on May 10, 2015. It costs $6.99, holds a 3.8 star rating from 116 US ratings, and its last iOS update shipped on June 12, 2022. Zolly arrived on January 27, 2025, free, with model packs at $1.99 to $4.99. That gap between 2022 and now is not neglect. It is the structural consequence of charging once. A $6.99 purchase made in 2015 funds no engineering in 2026, so the app artists reach for every single day gets whatever attention is left after the courses are shot. Ongoing maintenance has to be paid by ongoing revenue, which is exactly what app care exists to cover. Proko has revenue, staff, a studio, and a Marvel partnership. What it has never had is a monthly recurring revenue line. Run it as arithmetic rather than as a claim about his books, which he has not published since the 2021 Mixergy figure. Forbes counted 80,000 paying students in 2021 against 2.2 million subscribers. The channel has since doubled to 4.38 million.

Same price. Same product. Same customers. The only variable is whether the charge repeats, and that single variable is the difference between a good month and a company with a valuation. We work the general case through in the app versus course revenue math, and the conversion path in how to turn a course into a subscription app.

Drawing, guitar, chess, a language, handwriting, lifting, breathwork. If your subject is a practice rather than a body of information, you already have the hardest ingredient of a subscription business, and you are probably selling it as a one-time download. The test is simple. What does your student open on a Tuesday morning at 6am with twenty minutes and no plan? If the honest answer is "a free tool I built as a bonus", that free tool is your product and the course is the marketing. Proko's Timer is the cleanest illustration of this anywhere in the creator economy. An artist sits down, picks a reference pack, runs a life-drawing session on a Proko-built clock, and the transaction attached to that habit is zero dollars. Daily use is the rarest thing in software, and most creators give it away because it started as a bonus. There are seven ways creator apps turn followers into daily users, and every one of them assumes you charge for the habit. He gave away the teaching and sold the structure. Free YouTube lessons for fourteen years, paid courses with critiques and high-resolution reference behind them. That funnel works and it is not the problem. He built real software, not a mockup. Four tools, two of them native and on two app stores, under his own company name. Look through the creators at his subscriber count and count how many have shipped one. He priced the software as a souvenir. $6.99 for the thing artists open daily, $477 for the thing they finish once. The prices are the exact inverse of how often each is used. He proved the demand before pricing it. 80,000 people already paid him for instruction. That is not a hypothesis about willingness to pay. That is a customer list. Prokopenko solved the part almost nobody solves. He turned an atelier skill into an audience of millions and then into working software. The part still open is the one that decides whether Proko is a business he runs or an asset he owns, and it comes down to a single line in App Store Connect. That is the line Built by Foundry builds, launches, and runs for creators.

Proko does not sell a subscription or membership. Proko makes four tools. Skelly is a poseable anatomy model for iOS and Android, priced at $6.99 as a one-time purchase. Zolly is a perspective drawing app for iOS, Android, and Windows, free with model packs from $1.99 to $4.99. The Timer and the Value Study tool both run in a browser and are free. The Proko channel has 4.38 million subscribers. Forbes reported 2.2 million in May 2021, alongside more than 80,000 students paying for premium instruction on proko.com. A one-time purchase pays the developer once, while the cost of supporting an app continues every year through OS updates, device changes, and App Store policy changes. Skelly launched in May 2015 at $6.99 and its last iOS update shipped in June 2022. Recurring revenue is what funds recurring engineering.
