The Full Story

Im Jahr 2023 baute Iuliia 10 Produkte. Ihr Partner Marc startete Papermark – eine einfache Open-Source DocSend-Alternative. Die erste Version entstand an einem Wochenende.

Bauen für Wachstum

Beiden Projekte erreichten zeitgleich $500 MRR, aber nur Papermark fand Product-Market-Fit.

Die Kraft von Open Source

Open Source wurde zu einem mächtigen Vertriebskanal. Marcs Launch-Tweet wurde viral.

Versuche Produkte: 11 (10 gescheitert)
Zeit bis $45K MRR: ~1 Jahr
Kanal: Open Source + SEO

The journey, decisions, and context behind this milestone

How Iuliia actually did it

7/7 funnel stages sourced

Reconstructed from Iuliia's own published sources. Quoted claims are the founder's words, verified verbatim; anything marked as our analysis is exactly that.

Where the idea came from

Side project spinout

Papermark began as an off-hand wager by co-founder Marc Seitz, not a planned venture. A week before launch he tweeted a technical bet: he would only spend his weekend building an open-source, Vercel-Storage-only alternative to DocSend if the tweet cleared 50 likes. It cleared that bar easily, and he built the first version over the following weekend. The DocSend-alternative framing and open-source angle were present from this first tweet, not something layered on afterward.

“If this tweet get 50 likes, I get to build it on the weekend instead of cleaning the house.”

Marc Seitz, pre-launch "bet with my wife" tweet committing to build Papermark

Validation

Built first, validated after

OtherValidated

Before writing any code, Marc publicly committed to building Papermark only if his tweet describing the technical concept passed a 50-like threshold, using audience reaction as an informal go/no-go signal rather than a landing page or waitlist.

The tweet cleared the stated 50-like bar (it went on to 265 likes), which he treated as the green light to spend the weekend building.

“If this tweet get 50 likes, I get to build it on the weekend instead of cleaning the house.”

Marc Seitz, pre-launch "bet with my wife" tweet committing to build Papermark

MvpValidated

Marc built and shipped a bare-bones MVP (upload a document, share a link, see basic analytics) over a single weekend and launched it via a second tweet, without a separate pre-build validation step beyond the bet tweet above.

Iuliia describes the first version as minimal and built in one weekend, shipped without high expectations; it went on to attract paying customers within the milestone window, which is why the outcome is coded validated in hindsight even though Marc himself did not expect much at the time.

“The first version of Papermark took one weekend and was very simple”

Iuliia Shnai, "After 11 failed products, this founder hit $45k MRR in a little over a year" (Indie Hackers, first-person post under her own account)

First test users

Existing audience~10 usersFree testersX/Twitter (launch tweet)RedditDev.toProduct Huntpersonal outreach to people they already knew

The first users came from a mix of the founders' own social following, posts in existing communities, and direct outreach to people they knew personally, not from a single dominant channel. Iuliia does not break out how many of the first 10 came from each specific venue.

“We attracted our first 10 users by posting on social media, reddit, Dev.to, and Product Hunt.”

Iuliia Shnai, "After 11 failed products, this founder hit $45k MRR in a little over a year" (Indie Hackers, first-person post under her own account)

First paying customer

Existing audienceFree to paid upgrade$29

No founder source narrates the very first paying customer as a specific anecdote. The record's own first_customer milestone lands 30 days after launch, consistent with the structure Iuliia later described for the product generally: free document sharing available immediately, with the data-room product gated behind a trial whose main call to action is paying directly rather than talking to a salesperson. Papermark launched with a single paid plan at $29/mo, which is the price a launch-era paying customer would have hit.

Per Iuliia Shnai, LinkedIn post "31% of Papermark trial users convert to paid customers"

Acquisition channels, and whether they worked

Twitter / XLaunchWorked

A short, direct launch tweet naming the incumbent (DocSend) and the core mechanism (open-source, built-in analytics), one week after the public bet tweet that greenlit building it.

“An open-source alternative to DocSend that allows you to securely share documents with built-in analytics.”

Marc Seitz, "Introducing Papermark 1.0" launch tweet

Iuliia credits the launch tweet's own virality, without giving a specific mechanism for why it spread.

“He didn't have high hopes. But his launch tweet went viral too.”

SEO / ContentScalingWorked

After the first 10 users, the founders built out a content engine: free micro tools, DocSend-alternative comparison pages, how-to guides, and localized landing pages, run as their own defined 'building for growth' workstream separate from product work.

“We built free tools, alternative pages, how-to guides, and localized landing pages.”

Iuliia Shnai, "After 11 failed products, this founder hit $45k MRR in a little over a year" (Indie Hackers, first-person post under her own account)

Iuliia's own stated recommendation is to lean hard into the 'alternative to X' framing when the product is an open-source alternative to an established paid tool, since people actively search for alternatives.

“If your product is an alternative to some existing product, USE THAT.”

Iuliia credits freemium, alongside expanding the number of paid tiers over time, as a major driver of growth.

What didn't work

FundraisingCost: both

Before Papermark, Iuliia's first startup was an EdTech product she began building in 2019, straight out of a PhD in education research. It raised a pre-seed round, grew to a team of ten, and ultimately had to be shut down, with Iuliia laying off the entire team.

“In the end, that startup failed. We were a team of ten, and I had to fire everyone.”

Iuliia Shnai, "After 11 failed products, this founder hit $45k MRR in a little over a year" (Indie Hackers, first-person post under her own account)

She frames the core mistake as prioritizing fundraising over the business itself: she believed she needed to raise money and spent most of her time on investor conferences and pitching rather than building or selling, and separately leaned on an easy-but-unsustainable sales channel (AppSumo) rather than a durable one.

“I thought I needed to raise money. And I spent most of my time doing that”

Iuliia Shnai, "After 11 failed products, this founder hit $45k MRR in a little over a year" (Indie Hackers, first-person post under her own account)

What they did instead: Papermark was bootstrapped from the start with no outside funding, and both founders put their time directly into product and growth work rather than fundraising.

Product scopeCost: time

In 2023, in the depression-driven posting streak that followed her first startup's collapse, Iuliia taught herself to code and built roughly 10 small products. One, a LinkedIn post generator that she later branded Postli, went viral and reached $500 MRR at the same time Papermark did, but it did not sustain that traction.

“Both projects reached $500 MRR at the same time, but I couldn't find product-market fit for Postli and it slowly faded.”

Iuliia Shnai, "After 11 failed products, this founder hit $45k MRR in a little over a year" (Indie Hackers, first-person post under her own account)

Iuliia does not explain specifically why Postli failed to hold product-market fit after its viral launch and early $500 MRR mark; she states only that it faded. This is our reading of an otherwise unexplained outcome, not a claim she makes.

Our analysis, not the founder's claim

What they did instead: Attention shifted fully to Papermark once it kept growing past the $500 MRR mark where Postli plateaued; by January 2024 both founders were working on Papermark full time.

How it changed as they grew

At launch: 1 person (Marc Seitz alone, building and shipping the first version over one weekend.)

First 1k mrr: 2 people (Both co-founders working full-time: Marc on product, Iuliia on growth and content ('building for growth').)

Bootstrapped

Pricing restructure: single plan at $29/mo → four paid plans plus a free tier, ranging up to $349/mo with $79/mo as the most popular

Deliberate strategy of starting as simple as possible and adding complexity and higher tiers over time rather than launching with a complex pricing page.

“My advice is to start with as simple an offering as possible.”

Iuliia Shnai, "After 11 failed products, this founder hit $45k MRR in a little over a year" (Indie Hackers, first-person post under her own account)

What broke as they grew

Looking ahead from the $45K MRR mark toward a $1M ARR goal, Iuliia names reducing churn as one of two open problems, alongside continuing to invest in SEO and testing new channels. A July 2024 metrics tweet independently shows an 11.3% monthly churn rate, described there as already down 44% from a prior period, which is consistent with churn being an active, named constraint rather than a solved one.

“And we need to reduce churn.”
