Can a side project realistically reach $10K a month?

What does a side project making $10K a month actually look like?

A side project making $10,000 a month means a small business producing roughly $120,000 a year in repeatable revenue, and that is already a serious business by almost any normal definition.

For a subscription product, the customer math can look surprisingly manageable. At $100 a month, we need 100 paying customers. At $50, we need 200. At $20, we need 500. A specialist product charging $250 only needs 40 customers.

The harder part is what happens below the revenue line. $10,000 of monthly revenue can mean very different things depending on the business. A SaaS product with organic acquisition and cheap infrastructure could keep most of it. A mobile app might lose a chunk to store commissions, advertising, AI inference and infrastructure. A service business can make $10,000 while consuming almost every spare hour the founder has.

So when we discuss whether a side project can reach $10K a month, revenue is the cleanest benchmark. We should avoid quietly turning that into "$10K of passive income."

Monthly price	Paying customers needed for $10K/month
$10	1,000
$25	400
$50	200
$100	100
$250	40

How rare is it for a side project to reach $10K a month?

Reaching $10K a month is clearly possible, but the best large dataset we have suggests it sits well into the successful tail rather than anywhere close to the normal outcome.

RevenueCat's latest State of Subscription Apps study covers more than 115,000 subscription apps, over $16 billion in revenue and more than one billion transactions. Among newly launched apps, 17.3% reached $1,000 in monthly revenue during their first two years. Only 4.6% reached $10,000.

The drop is steep. Roughly three quarters of the apps that managed to reach $1,000 still failed to reach $10,000 within the same two-year window.

MicroConf gives us another view from independent SaaS. Its State of Independent SaaS data found that 28% of surveyed companies were below $1,000 MRR, which was the largest revenue group in the survey. MicroConf also reports that 65% of companies had only one to ten paying customers and more than half had fewer than 50.

Those samples have limits. RevenueCat covers subscription apps using its infrastructure, while MicroConf naturally attracts people who are already serious about bootstrapped software. Neither dataset counts every abandoned weekend project or half-built repository.

If anything, including those abandoned attempts would make the overall odds worse.

Milestone	Share of new subscription apps reaching it within two years
$1K monthly revenue	17.3%
$10K monthly revenue	4.6%
Share reaching $1K but failing to reach $10K	about 73%

Are the $10K-a-month side-project success stories actually real?

Yes, there are enough documented $10K-a-month side projects that we can stop treating the target as some internet myth.

Stagetimer is a good example because the original product was almost absurdly narrow. Lukas Hermann watched a friend in video production physically run back and forth to control a countdown timer, then built a remote version. Indie Hackers later reported Stagetimer at $15,000 MRR and roughly $20,000 in total monthly revenue once one-time purchases were included.

Parqet started just as narrowly. Sumit Kumar built a portfolio tracker for German investors while working at Stripe. The first version handled one broker, one language, one currency, one market and one asset type. He publicly reported passing €17,000 MRR after roughly a year of monetization. The business later grew dramatically beyond that early side-project phase; an Indie Hackers profile subsequently put Parqet at $108,000 MRR.

Bank Statement Converter solved another extremely specific problem: turning PDF bank statements into structured files. Angus Cheng publicly recorded the product reaching $10,000 MRR, and his current Indie Hackers profile lists the business as active at roughly $13,000 a month.

More recent founder stories continue to appear. In a recent Indie Hackers interview, Mykola Polotnianko said BlogToPin had reached roughly $15,000 MRR after several years of indie hacking and multiple failed products.

These cases vary enough that we can draw a useful conclusion from them. $10K businesses emerge from tiny B2B tools, fintech products, document utilities and content-driven software. There is no single magic category doing all the work.

The survivorship bias appears when we look at those examples and forget the much larger number of projects that never get close.

How long does it actually take a side project to reach $10K a month?

A side project can reach $10K a month surprisingly fast once it has real traction, but getting to the product that has that traction can take years.

RevenueCat found that among apps which eventually reached $10,000 in monthly revenue, the median journey from launch to the milestone was 109 days. Gaming products were even faster at 53 days.

That number is easy to misunderstand. Only 4.6% of newly launched apps reached $10,000 within two years in the first place. The 109-day figure describes the successful group rather than the typical launch.

Founder histories show what the aggregate misses. Stagetimer needed roughly three years to become a $10K MRR business. BlogToPin's founder spent about four years indie hacking, including roughly a year and a half of failed products before finding the idea that worked. Mubashar Iqbal, who eventually built a portfolio producing more than $10K a month, has said he built around 120 side projects over his career.

The first successful revenue graph hides a lot of prehistory. We see the product that worked; the founder remembers the projects that died, the marketing channels that failed and the years spent learning what people would actually pay for.

The pattern is pretty simple: the winning product may grow quickly, while finding it can be painfully slow.

Can someone really build a $10K-a-month side project while keeping a full-time job?

Yes, people have reached $10K a month while employed full-time, although some of the best documented cases make the word "side" sound rather generous.

Parqet is probably the clearest example. Sumit Kumar built it while holding his job at Stripe and raising a newborn. During the most intense period, he described working roughly from 7 a.m. to 9 a.m. before work and then again from around 8 p.m. until midnight.

By the time Parqet was above €17,000 MRR, Kumar had also started using freelancers and had hired an employee. Roughly ten people were contributing in some form, although many were part-time.

Other founders made the jump earlier. Stagetimer eventually became Lukas Hermann's full-time business. Its progression from side project to serious SaaS is common because a growing product creates support, sales, technical and operational work that did not exist at the beginning.

This changes how we should interpret the claim. Keeping a job while reaching $10K is possible. Doing it comfortably on four relaxed hours every weekend is much harder to support with real examples.

Does a side project need thousands of users to make $10K a month?

No, and this is one of the main reasons $10K a month remains attainable for a tiny business today.

A $200-per-month product needs 50 customers. A $500 specialist tool needs 20. Even at $50, we are talking about 200 paying accounts rather than millions of users.

MicroConf's independent SaaS data is useful here because it shows how small these businesses can be. More than half of surveyed companies had fewer than 50 paying customers. Some of those businesses obviously remain small in revenue, but the figure illustrates how far pricing can move the equation.

The consumer-app economics are harsher. RevenueCat's current benchmark puts median year-one realized lifetime value per payer at about $23 globally. High-priced apps do much better, with year-one realized value above $60 per payer, while low-priced apps sit much lower.

That is why a tiny B2B product can beat a much more popular consumer app financially. A founder selling a painful workflow fix to 100 companies may have a clearer route to $10K than someone trying to attract 50,000 casual users.

Is a boring niche actually a good place to find a $10K side project?

Yes, because a $10K-a-month business needs a valuable pocket of demand rather than a giant mainstream market.

Look at the products again. Stagetimer began with remote countdown timers for event production. Bank Statement Converter turned PDFs into spreadsheets. Parqet initially focused almost entirely on German investors using a limited set of brokers.

Those markets sounded small because the founders described the problem precisely.

The math works in their favor. Suppose a niche contains 10,000 businesses that genuinely have the problem. At $100 a month, reaching $10K requires 100 customers, or 1% of that addressable group. A founder can build something meaningful without dominating an industry.

Small niches also simplify the product. Customers ask similar questions. Search terms become more specific. The homepage can speak directly to one problem. Word of mouth travels inside the same professional circles.

We should still care about market size because some niches genuinely run out of buyers. But side-project founders often make the opposite mistake: they reject a useful market because it looks too small for a venture-backed startup.

A market can be tiny by VC standards and enormous relative to a $120,000 annual revenue target.

Is getting customers now harder than building the side project?

For many software side projects today, getting customers is clearly the harder half of the job.

RevenueCat's current data makes the supply explosion hard to ignore. Roughly 2,000 new subscription apps were launching each month at the start of 2022. That figure is now close to 15,000 a month, about seven times higher.

Customer spending has stayed much more concentrated. Apps launched before 2020 still collect 69% of subscription revenue in RevenueCat's dataset. Apps launched in 2025 or later account for only about 3%.

Developers can build and launch at extraordinary speed, while trust, attention, search rankings, referrals and existing customer relationships still accumulate slowly.

The founder examples tell a similar story. Stagetimer reported that at least 40% of its volume came from SEO, with word of mouth contributing another important stream. Parqet built sharing into the product and used affiliates while spending essentially nothing on conventional advertising in its early period. Bank Statement Converter initially experimented with roughly $1,000 a month in paid advertising and brought in only around $200 from it, according to Angus Cheng. He eventually leaned much more heavily on content and organic search.

MicroConf's survey also puts SEO and word of mouth among the highest-impact acquisition channels for independent SaaS founders.

These days, a technically decent product can be created very quickly. Finding a repeatable way to put that product in front of people who will pay remains much harder.

Has AI made reaching $10K a month easier or harder?

AI has made the production side of a $10K side project dramatically easier while increasing the number of competitors fighting for the same customers.

The production advantage is already visible in practice. A founder can now generate interfaces, debug code, write database queries, create marketing assets and prototype features with tools that would previously have required much more time or outside help.

BlogToPin gives us a recent real-world example. Founder Mykola Polotnianko told Indie Hackers that he built much of the initial product by vibe coding and copying components from Tailwind UI. The business is currently around $15K MRR.

The competition effect is visible in RevenueCat's much broader numbers. As seen above, monthly subscription-app launches have increased roughly sevenfold in four years. RevenueCat says the sharpest acceleration on iOS began alongside the rise of AI-assisted development.

AI products also have mixed economics once customers arrive. RevenueCat currently finds that AI apps generate roughly 39% more monthly realized lifetime value per payer than non-AI apps, yet its broader analysis also finds faster churn among AI-powered products.

AI helps a founder reach the starting line faster. The advantage disappears quickly when thousands of other founders receive the same tools.

A simple product can still make $10K. Increasingly, the hard-to-copy part has to come from the market knowledge, distribution, data, workflow or reputation surrounding the code.

Does a $10K-a-month side project become passive income?

Sometimes a $10K side project can become remarkably low-maintenance, but true passivity is an unusually good outcome rather than part of the standard package.

Bank Statement Converter came close for a while. While passing $6,000, $7,000, $9,000 and eventually $10,000 MRR, Angus Cheng repeatedly wrote that he was doing very little beyond fixing document problems and answering support requests. His current Indie Hackers profile still lists the business as active at roughly $13,000 a month.

That is a powerful example because software really can decouple revenue from hours worked.

Stagetimer shows the other trajectory. Lukas Hermann said that products tend to take on a life of their own as they grow and that he expected to keep investing years into the business. Professional customers were connecting Stagetimer to more equipment and more complicated event workflows, which increased the product's technical demands.

Both outcomes are plausible. Some products settle into a stable niche with organic traffic and low support. Others create more work as revenue rises.

So $10K MRR can buy a founder tremendous leverage. It does not automatically buy freedom from customers, bugs or competition.

Is $10K in monthly revenue actually a good business?

A $10K-a-month side project can be fantastic or surprisingly mediocre depending on how much money and time disappear while producing that revenue.

A high-margin software product acquired through search or referrals can keep a large share of its $10,000. Bank Statement Converter once reported business expenses of only around $770 a month while generating roughly $10K MRR, an unusually strong cost structure.

Paid acquisition can produce the opposite result. RevenueCat's current app revenue calculator illustrates how quickly the economics change when store commissions, marketing, servers, AI costs and tax are included. Its example $9.99 subscription business produces $2,599 in gross monthly revenue but only $153 of monthly net profit once the assumed costs are applied.

Founder time belongs in the calculation as well. A product producing $6,000 of profit while requiring ten hours a month is a very different asset from one producing the same profit while consuming every evening.

For a side project, we should care about four numbers together: revenue, profit, hours worked and how stable the revenue is.

Monthly revenue	Operating margin	Monthly operating profit
$10,000	90%	$9,000
$10,000	70%	$7,000
$10,000	40%	$4,000
$10,000	20%	$2,000

Is B2B or a consumer app the easier route to $10K a month?

For a solo founder without a huge audience, a narrow B2B product often gives us the cleaner revenue equation, although the latest app data shows that consumer products can break out faster.

RevenueCat found that Business apps were slow to get started. Among successful products, reaching the first $1,000 in monthly revenue took a median 113 days. Only 1.6% of newly launched Business apps reached $10,000 within two years, compared with 4.6% across all categories.

Gaming sits at the other extreme. About 8.9% reached $10K within two years, the highest rate among the categories RevenueCat highlights, and successful games reached the milestone in a median 53 days.

Those numbers do not make gaming the obvious choice for a side-project founder. Consumer products typically need far more users, and their acquisition, store and churn economics can be brutal.

B2B gives us pricing power. Fifty customers paying $200 a month are enough. A consumer app charging $10 needs 1,000 active paying subscribers, plus a continuing stream of new ones to replace churn.

The practical question is less about choosing B2B or consumer in the abstract and more about where the founder already has an unfair way to reach buyers.

What separates a $500-a-month side project from a $10K-a-month one?

A $10K-a-month side project usually has a repeatable growth mechanism, while a $500 project can survive for quite a while on a few lucky customers and launch traffic.

RevenueCat's funnel puts numbers around that jump. 17.3% of new subscription apps reached $1,000 per month, while 4.6% reached $10,000. The first milestone is already difficult. Scaling another tenfold eliminates roughly three quarters of the projects that made it that far.

Features alone rarely explain the difference.

Stagetimer built search traffic and referrals. Parqet made portfolios shareable and added an affiliate system. Bank Statement Converter found search demand around an extremely literal problem. WordPress products can piggyback on an existing plugin ecosystem. Other small SaaS companies grow through integrations, marketplaces, programmatic pages, outbound sales or free tools.

At $500 a month, the founder may still be discovering where customers come from. By $10K, there usually has to be an acquisition channel that can work over and over again.

That repeatability is one of the clearest differences between a promising project and a small business.

What is the most realistic way to build a $10K-a-month side project today?

The most realistic route today is to solve a narrow problem that already costs people time or money, charge enough that a few hundred customers matter, and find one acquisition channel that can keep working without constant launches.

The successful examples are much less glamorous than the usual startup advice. Parqet began with one country and one type of investor. Stagetimer solved a countdown-timer problem. Bank Statement Converter describes almost its entire value proposition in its name. BlogToPin found a very specific group of publishers who wanted Pinterest traffic without manually creating and scheduling every pin.

The pricing also matters early. A founder charging $100 needs 100 customers. That makes $10K possible inside a niche that would look microscopic to a venture capitalist.

Then we need proof that customers can arrive repeatedly. Search can do that when people already type the problem into Google. Outbound can work when each account is valuable. Marketplaces work when customers already congregate around another product. Sharing can work when using the product naturally puts it in front of another potential user.

AI now makes the first version much cheaper to create, which is genuinely useful. It also means building for months before testing demand makes even less sense than it used to.

The fastest part of a modern side project can easily be the code. Finding something people keep paying for remains the real job.

So can a side project realistically reach $10K a month?

Yes, a side project can realistically reach $10K a month today, but we should treat it as a strong success rather than the expected payoff from launching one competent product.

The base rate is the part worth remembering. RevenueCat's latest dataset puts the two-year $10K hit rate at 4.6% for newly launched subscription apps. MicroConf finds 28% of independent SaaS companies below $1,000 MRR. Meanwhile, almost 15,000 new subscription apps are now appearing every month.

There is equally strong evidence that the upper tail is real. Stagetimer, Parqet, Bank Statement Converter, BlogToPin and many other small products have crossed the threshold without needing venture funding or hundreds of employees. Several started while their founders still had jobs. Some were built around problems so narrow that they would barely qualify as startup ideas in a conventional pitch deck.

The harder truth is what happens between the idea and the outcome. Stagetimer took years. BlogToPin followed years of indie hacking and failed products. Parqet demanded intense hours around a full-time job before becoming a much larger company. Even RevenueCat's very fast 109-day median applies only to the small group of apps that actually make it to $10K.

So $10K a month is a rational target today. It is ambitious, uncommon and demonstrably achievable.

The best projects also make sense before they reach that number. A side project earning $1,000 a month has proved that strangers will pay. At $3,000, it can materially change someone's finances. At $5,000, leaving a job starts becoming a real decision for some founders. If the economics keep working from there, $10,000 becomes the next stage of an already useful business rather than an arbitrary line separating success from failure.

We do not need millions of users, venture money or a huge team to build a $10K-a-month side project. We do need a good problem, enough pricing power, repeatable distribution and enough persistence to survive the many projects that never get there.
