HelpKit: $10K MRR Turning Notion Docs into Help Centers, and Why the Solo Founder Stopped Sharing Revenue
HelpKit, which turns Notion documents into professional help centers, reached $10K+ MRR and 400+ customers as a solo, bootstrapped SaaS. Founder Dominik Sobe shared exact revenue from day one and grew with it, then deliberately stopped publishing numbers at $10K MRR after copycats began cloning his landing page. A rare record of how to exit build-in-public.
This solo SaaS grew by sharing every revenue number. So why did the founder suddenly stop?
The answer has less to do with the numbers and more to do with who was reading them.
- How the numbers ran from $1,020 MRR five months after launch to $10K+ MRR
- Why using Notion as the CMS, and never building an editor, worked
- What distribution looked like: one free tool and hundreds of hand-written emails
- Why revenue updates stopped at $10K MRR, and why the business can't be measured since
HelpKit turns documents written in Notion into polished help centers. It carries $10K+ MRR and more than 400 customers.
It’s run by one self-taught developer, with zero outside capital.
What makes the case worth recording is the trajectory rather than the amount.
Founder Dominik Sobe disclosed his revenue from day one and grew as a build-in-public practitioner. Then, on reaching $10K MRR, he cut off the numbers himself.
The trigger was copycats cloning his landing page wholesale.
The build-in-public story usually gets told up to “sharing helped me grow.” A documented decision to stop sharing, with reasons, is rare.
$1,020 at five months, then on to $10K
| Period | Figure |
|---|---|
| ~2021 | Needing a help center for his own mobile app and finding existing tools bloated, he hits on using Notion as the CMS |
| Feb 2022 | Five months after launch: $1,020 MRR / $12,240 ARR. 408 signups, 51 paying customers, 0% churn. Plan mix: 35% on $19, 65% on $29 |
| Pricing path | Raised gradually from $19/month at launch; some customers now prepay $1,000/year |
| Jul 2025 | $10K+ MRR, 400+ customers including universities and enterprises (per Superframeworks) |
The early figures come from Sobe’s own Indie Hackers AMA.
The $10K MRR, the 400 customers, and the decision to stop sharing come from the Superframeworks case study.
Sobe was 24 at the time. After several failed attempts, HelpKit was his first product to reach $1,000 MRR.
Not building an editor was the real design choice
HelpKit doesn’t build an editor.
Customers write help articles in Notion, and HelpKit serves them as a searchable, professional help center.
That split pays off twice.
It slashes the build. Document editing, the heaviest part of a product like this, goes wholesale to Notion, so a solo developer can focus on rendering and delivery.
And nothing changes in the customer’s workflow. A team already writing internal docs in Notion gets a help center without adopting a new tool.
It also means distribution is decided from the start.
People who want a help center on Notion have clear search terms and communities. You can simply wait for them inside Notion’s enormous ecosystem.
It’s the same platform-leverage pattern as Potion, the Notion website builder that went from indie project to a $300K exit.
Line up micro-SaaS tools by real numbers: HelpKit at $10K MRR, Data Fetcher for Airtable at $23K MRR, and Bannerbear, built on an image-generation API, at $10K MRR.
Tools wedged into the gaps of bigger platforms cluster in one band.
Distribution: one free tool and hundreds of hand-written emails
The lead channel in the Superframeworks case study is a free “Notion Table Generator.”
A free tool solving a small Notion-user problem ranked well in search. It got shared across Reddit and Facebook groups and kept generating organic traffic for months.
Zero paid ads.
It’s textbook engineering-as-marketing, and the funnel collects exactly the prospects the paid product wants.
The other pillar was manual labor.
Early on he sent hundreds of cold emails, each one personalized, and ran demos and onboarding by hand.

He’s also described building the product while traveling, working from cafes and co-working spaces.
A cost structure that light is what subsidized the manual approach.
At $10K MRR, the revenue updates stopped
HelpKit’s numbers were disclosed in detail through the 2022 AMA.
At $10K MRR, though, Sobe stopped publishing exact revenue.
Copycats had appeared, cloning his landing page outright. The published revenue was working as a blueprint: this market, with this design, yields $10K a month.
Build-in-public is a free acquisition asset. It also lowers the cost of imitation.
Sharing beats the cost of being copied only while the business is too small to be worth copying.
That’s the boundary this case draws.
- The 0% churn at the AMA was measured over 51 customers, too few to call a durable metric
- A product wholly dependent on Notion's API and behavior carries a standing risk: if Notion ships a richer official publishing feature, the foundation moves
The current state, with university and enterprise customers among the 400-plus and $1,000-a-year prepayments, is the return earned in exchange for that risk.
After the numbers stopped, HelpKit can’t be measured from outside
Ending disclosure at $10K MRR also marks the edge of what can be checked. Growth and churn since then are private, and the 400-plus customer count is a single reported snapshot. Whether the business is still growing or has flattened can't be confirmed from outside.
Copycats were the reason disclosure stopped.
Seen that way, the gap is rational from the business’s side. From the reader’s side, it’s where the record ends.
For HelpKit, full transparency helped only up to $10K MRR, while the business was still too small to be worth copying.
The early tactics come with conditions too.
Hundreds of personalized cold emails and hand-run demos were labor-intensive work that a nomadic life with flexible hours made possible. A different setup or life wouldn’t supply the same volume.
