5 million downloads and $17,000 a month, and not a dollar of it came from ads.
That's Postiz, a social media scheduling tool competing in one of the most crowded categories in software. Thousands of schedulers exist. Buffer and Hootsuite have been there for 15 years.
So how does a bootstrapped solo product even get seen in that market?
Two words: open source marketing.
Nevo David, the founder, went on Starter Story with Pat Walls and laid out his entire playbook. Not the vague "build community" advice. The actual step-by-step launch sequence he's run for his own product and for companies he consulted for.
I pulled out every number and every step. Here's the full breakdown.
Who is Nevo David?
Nevo wasn't an "open source person." He was a developer for years, grinding through startups that went nowhere.
Then he met a few people in a co-working space who were building Novu, an open source infrastructure tool for sending notifications. He joined. Over two years, the project went from 0 to 32,000 GitHub stars.
He'd never seen growth like that in his life.
So he did the logical next thing: spent a year as a niche consultant teaching companies how to grow with open source. It paid, but it also meant endless meetings. The stress freaked him out (his words).
He quit consulting to go back to building. The result is Postiz: an open source social media scheduler that posts to 25 platforms, with AI baked in.
Everything he builds now is open source. Here's why.
Why Open Source Is a Distribution Hack
Nevo's core argument: in 2026, anyone can build almost anything. AI writes the code. Every idea you have, somebody else can ship too.
So the code isn't the moat. Distribution is.
Open source puts your project in front of millions of developers. The twist: those developers will probably never pay you. Nevo says this straight. They're not a buying persona, so don't build elaborate schemes to charge them.
Treat the open source version as a free tier that costs you nothing, because users run it on their own machines.
What developers give you instead of money:
- Word of mouth. A developer self-hosts Postiz, then recommends it at work where someone actually has budget. Nevo sees developers "selling" Postiz on social media every single day.
- Free SEO. Strangers write blog posts, reviews, and tutorials that rank for your keywords.
- Backlinks from open source directories with serious domain ratings.
- Faster iteration. Contributors file bugs and ship fixes. Nevo is honest here too: contributions don't exactly make you more productive, but the feedback loop is worth it.
- Credibility. Non-technical buyers check the GitHub page, see commits from three days ago, and trust that the product is alive.
- Enterprise money. The biggest checks in open source come from enterprises that want to self-host AND want paid support. That's where funded open source companies make their real revenue.
And the fear everyone has ("someone will steal my product") turns out to be mostly noise. People have cloned Postiz and relaunched it under different names. Nevo stressed about it, checked back two weeks later, and found every clone abandoned.
You are the brand. The copycat is always one step behind. They give up.
The Real Numbers Behind Postiz
Nevo shared his dashboard on camera. Here's where the business stood at recording:
- $17K MRR on a standard SaaS pricing ladder (Standard, Team, Pro, Ultimate)
- 472 paying subscribers
- 3,830 trials since August 2025
- 21% trial-to-paid conversion
- 19% churn (high, and he's working on it)
- Around 80% margins
Two things jump out at me.
First, that 21% trial conversion is strong. A big chunk of that comes from trust built before the trial even starts: people arrive already convinced because they found the project through GitHub, Reddit, or a developer they know. Your funnel gets easier when the market warms itself up. If your own trials convert below 10%, the problem usually isn't the product, it's what happens between signup and day 7 (this guide on lead nurturing strategies covers that gap well).
Second, 19% churn would kill most SaaS products. Postiz survives it because the top of the funnel is free. When distribution costs you nothing, you can afford leaks while you fix them.
The cloud product and the self-hosted version are identical, by the way. Nevo doesn't gate a single feature. Self-hosters just do the hard work themselves: approving every social platform's API access, running their own server. That friction is the paywall.
The Open Source Launch Playbook, Step by Step
This is the exact sequence Nevo ran for Postiz and for his consulting clients. The goal of the whole thing is one metric: enough traffic in a short window to hit GitHub's trending feed. Once you're trending, stars, Discord members, and contributors compound on their own.
Step 1: Treat your GitHub repo as your landing page
Your README is your homepage for developers. Nevo says to treat it better than your actual website.
- If a known competitor exists, position as "the open source alternative to X". Fastest context you can give anyone.
- Pick a license: MIT, Apache 2.0, or AGPL-3.0. Think about which one before you launch, not after.
- Create GitHub issues for features you want built. Developers landing on your repo don't know what to work on. An open issue lets them say "assign me" instead of guessing. You get code faster.
- Open a Discord. Copy the channel structure from the Postiz server if you want a template.
- Write deployment docs and ship a Docker image. No Docker, no self-hosters. They churn before they ever clone.
Step 2: Set up your launch accounts two weeks early
- Hacker News: register early, aged accounts do better.
- Reddit: build some karma first or your posts get auto-filtered.
- Lemmy: the self-hosted Reddit alternative. Nevo says it's mediocre for everything except open source, where it's "crazy". His posts there reliably pull 100+ upvotes.
- dev.to, Medium, Hashnode-style blogs: create accounts and profiles.
Step 3: Publish launch articles
Write "how I built X" and "I just open-sourced X" posts on the dev blogging platforms. Later, add listicles ("top 10 open source projects to check in 2026").
The hidden channel here is Google Discover. Nevo checked his analytics: Discover is the main traffic source for his dev.to and Medium articles. So invest in the title and the cover image like a YouTuber invests in thumbnails.
Step 4: Show HN
Post "Show HN: [project name]" and link to the GitHub repo, not your marketing site. Hacker News is picky, but it loves open source. Front page is worth roughly 10,000 visits.
Step 5: Reddit, specifically r/selfhosted
Self-promotion gets you banned almost everywhere on Reddit. r/selfhosted is the exception: if your project is open source, that community is literally waiting for you to promote it.
Nevo's rules: write like a human building in public, use "I" not "we", stay humble, ask for a star. Then repost every month with each new version. People want to see the changelog.
Crosspost to r/webdev and r/programming. Building in AI? Add r/LocalLLaMA, r/AI_Agents, and the LangChain subreddit.
Reddit as a primary growth channel is more repeatable than people think. I broke down how a Mac app got to $150K a year with the same motion in the Reddit and SEO playbook behind Elephas.
Step 6: Fire everything the same week
X, LinkedIn, your newsletter, whatever audience you have. All of it points to the GitHub repo, all in the same week.
Concentration is the trick. Spread the same effort over a month and you never trend. Stack it in one week and GitHub's algorithm does the rest.
The Stack Behind the 80% Margins
Nevo runs lean, and open source itself cuts his bills:
- Railway for the backend, Vercel for the Next.js marketing site
- Resend for transactional email, Cloudflare R2 for storage, dub.co for short links and the affiliate program
- Plausible for analytics, Semrush for SEO, Ahrefs on the $20/month dashboard-only plan
- OpenAI and fal.ai for the AI features
- Video transcoding (so posts never fail on format) is his biggest expense at $600/month
- Cursor at $20/month, WebStorm as the IDE, Beehiiv for the newsletter
- Discord for customer support: $0
- GitHub Copilot, Sentry, and GitHub Actions: free, because open source projects don't pay
That last line is an underrated perk. Half the modern dev stack waives its fees the moment your repo is public.
What Happened Next (and the Advice Nevo Would Give Himself)
This interview captured Postiz at $17K MRR. It didn't stay there.
Nevo later repositioned the product around agentic social media, and revenue jumped to $143K MRR within four months. I covered that whole second chapter in the Postiz agentic SaaS pivot breakdown. Read the two together and you get the full arc: open source builds the distribution engine, then a sharp pivot pours fuel on it.
His parting advice on Starter Story was about what comes before any of that. After years of failed startups, he stopped and read the fundamentals: Traction, Hormozi's $100M Offers, Russell Brunson on lead generation. Only then did his decisions get smarter.
His split: half your time learning, half building. Most founders who skip the learning half grind on a doomed B2C idea for a year, shut it down, and only then realize they should've gone B2B.
Expensive lesson. Cheaper to read it.
FAQ
Does open source actually make money?
Yes, but not from developers. Postiz makes $17K/month from a cloud-hosted SaaS tier sold to non-technical users, while the free self-hosted version drives distribution. The largest open source revenue usually comes from enterprises paying for self-hosted deployments with support contracts.
Won't competitors steal my code if I open source it?
They'll try, and it mostly won't matter. Postiz has been cloned and relaunched multiple times, and every clone died within weeks. The original author owns the brand and the community. Forks start one step behind and stay there.
Which license should an open source SaaS use?
The three Nevo points to are MIT, Apache 2.0, and AGPL-3.0. MIT and Apache are permissive and maximize adoption. AGPL-3.0 forces anyone who hosts a modified version to publish their changes, which is why commercial open source SaaS products often pick it for protection.
Where should I launch an open source project?
Five channels, all in the same week: launch articles on dev.to and Medium (Google Discover traffic), a Show HN post linking your GitHub repo, r/selfhosted on Reddit, Lemmy, and your own audience on X, LinkedIn, and email. The concentrated spike is what gets you onto GitHub trending.
Want more playbooks like this, from the founders themselves?
Every week on the Profitable Founder Podcast I sit down with bootstrapped SaaS founders doing $100K to $10M a year and pull out the exact numbers and moves behind their growth. No theory, just what worked.
