Look, three months ago I posted a screenshot of my affiliate dashboard to Twitter and got DMs from about fifteen people asking the same question: "How?"
Not how I made the money — the money itself wasn't even that impressive. The question was how does it keep showing up every single month without me doing anything?
Because here's the thing. For the first two years of trying to build income online, I chased every shiny thing. Dropshipping. Freelancing. Selling courses. Building SaaS products from scratch. And every single time, the income graph looked like a heartbeat — spikes followed by flatlines. I'd grind for a month, make a chunk of change, then watch it evaporate the moment I stopped working.
Then I stumbled into SaaS affiliate marketing through developer tools. And for the first time in my life, I saw income that didn't reset to zero when I took a week off.
Here's my real numbers. Last month my recurring affiliate revenue was $847. The month before that it was $712. The month before that it was $598. The trend line is the part that matters. It's not because I hustled harder. It's because the commissions keep compounding. Someone I referred seven months ago is still paying their subscription, and I still get my cut. Every. Single. Month.
Let me walk you through exactly how this works, why it fits the build-in-public ethos perfectly, and where the real opportunity is right now.
My Affiliate Income Journey — The Ugly Truth
I want to start with honesty because that's the whole point of build-in-public. Sharing only the wins is just marketing. Sharing the losses is what actually helps people.
In 2023, I made $2,400 total from affiliate links across multiple programs. Sounds okay until you realise I spent roughly 80 hours writing content that month. That's $30 an hour. I could've freelanced for more.
In 2024, I switched focus almost entirely to SaaS affiliate programs for developer tools — hosting, databases, monitoring tools, productivity software, and eventually AI infrastructure platforms. By December 2024, I was clearing $400-500 per month in mostly-recurring commissions from a portfolio of about thirty blog posts and a few YouTube videos.
In the first half of this year, I leaned hard into AI API affiliate programs specifically. That single category now represents roughly 70% of my total affiliate revenue. My dashboard from last month tells the whole story: the bulk of my income came from referrals who signed up four, five, even six months ago and never left.
That's the magic word I want to drill into your head: never left.
Developer tools have insane stickiness. Once someone integrates an API into their production app, switching it out isn't a five-minute job. It's a weekend of refactoring plus regression testing plus angry users if something breaks. So referrals stick. And every month they stick, you get paid.
Why the Monthly Payout Model Changes Everything
Most affiliate programs I've tried pay you once and forget you. You refer someone to a $200 course, you get $40, you never hear from them again. That's not passive income. That's a commission. There's a massive difference.
Recurring commission programs flip the entire equation. You do the work once — write the article, make the video, post the thread — and you get paid repeatedly for as long as the customer keeps paying.
Let me show you the math I actually run in my head when I'm deciding whether to write a new piece of content.
Say I spend four hours building out a solid tutorial. I publish it on my blog, link my affiliate code, and the piece starts picking up search traffic. Within a few months it's getting somewhere between 300 and 500 views per month from organic search.
From those views, about 1-2% of people click my affiliate link. Of those clickers, roughly 2% convert to a paid signup. That gives me somewhere between 0.3 and 0.6 new referrals per month from that single article.
Now here's where it gets good. Each of those referrals is worth roughly $3-5 per month in combined first-order and recurring commissions. Some months it's on the low end, some months it's higher. Over the course of six months, that one article has typically generated 2-4 active referrals. The recurring income from those referrals alone is $6-20 per month. The first-order commissions I collected along the way add another $15-30 to the pile.
So my four hours returned $75-150 in the first six months, plus ongoing monthly income that just keeps dripping in.
Multiply that across ten articles and I'm looking at $60-200 per month in recurring commissions, plus the steady stream of new first-order payouts as fresh referrals sign up.
Multiply across fifty articles? That's where the real number shows up: somewhere between $300 and $1,000 per month. All from work I did once.
That's what passive income actually looks like. Not "passive" because you never did anything — passive because you did it once and it keeps paying.
The AI API Category Was My Breakthrough
I'd been doing the SaaS affiliate thing for over a year before I started focusing on AI API platforms specifically. The shift happened almost by accident — I'd been writing about AI development on my blog, and one of the platforms I was using reached out with an affiliate offer.
The numbers on that first program made me do a double-take. First-order commissions of 15%. Recurring commissions of 8%. Premium tier referrals at 10%. All on subscriptions that developers were already paying for anyway.
When I ran the comparison in my spreadsheet, the math was obvious. Promoting a $50 per month AI API subscription at 8% recurring gives me $4 per month, per referral, potentially for years. Promoting a one-time $50 course at 20% gives me $10 once and nothing after that. The course pays better that day. The API subscription pays better every day after.
And the AI API market isn't some tiny niche. These platforms offer 150+ models through a single integration. Developers need multiple models for different tasks. Once they centralize their API access through one platform, they're not churning. They're adding more usage over time. That means the average revenue per referral actually grows, which means my commission grows.
I want to be transparent about something here — this isn't theoretical optimism. This is what I see in my dashboard. My average monthly commission per active referral has climbed roughly 22% over the past six months because the people I referred are spending more, not less, on their API access.
What "Build in Public" Actually Means for Affiliates
The build-in-public movement gets dismissed sometimes as just people posting screenshots of their Stripe notifications. There's some truth to that criticism. But the underlying principle is what makes affiliate marketing work for developers.
The principle is: share the real process, including the messy parts.
When I write an affiliate review of an AI API platform, I'm not regurgitating the marketing page. I'm showing the integration code I actually wrote. I'm showing the dashboard where my referrals are tracked. I'm showing the income. I'm explaining what worked and what flopped.
That kind of transparency does two things. First, it builds trust with readers who can immediately tell whether someone is speaking from experience or just rewording a press release. Second, it attracts the kind of audience that the affiliate program wants — developers who are going to use the product seriously, integrate it into real projects, and stay subscribed for the long haul.
High-quality referrals are the difference between an affiliate program that's a side hustle and one that's an actual income stream. Programs offering recurring commissions reward you specifically for sending them customers who stick around. Build-in-public content is how you attract those customers.
The Mistakes I Made (So You Don't Have To)
I want to share the failures too because they cost me real money and real time.
**Mistake
1: Promoting too many programs at once.** In 2023 I had affiliate links to twenty-three different products scattered across my content. Conversions were terrible because readers couldn't tell what I actually used versus what I was just collecting a commission on. I cut my active programs down to seven, and my conversion rate jumped dramatically.
**Mistake
2: Writing thin content.** My early posts were 600-word "top 5 tools" listicles. They ranked briefly, then disappeared. The articles that now drive my recurring income are 2,000-3,000 word tutorials that solve a specific problem and integrate the affiliate tool as part of the actual solution.
**Mistake
3: Ignoring recurring programs.** I treated all affiliate programs the same. They're not. A one-time 30% commission on a $30 product is $9 once. An 8% recurring commission on a $50 monthly subscription is $4 every month for as long as the customer stays. Over a year, the second one pays four times more. Over three years, twelve times more.
**Mistake
4: Not tracking my numbers.** For my first year I had no idea which articles were actually generating referrals. I started tagging every affiliate link with UTM parameters and checking my dashboards weekly. Suddenly I knew exactly which topics and formats converted, and I could double down on them.
What to Look for in an Affiliate Program
Based on everything I've learned the hard way, here's my checklist for evaluating any developer-focused affiliate program.
First, does it offer recurring commissions? If the answer is no, I usually pass unless the one-time payout is exceptionally high. Recurring is where the compounding happens.
Second, what's the commission rate on first orders versus renewals? The programs that have treated me best offer a meaningful first-order commission (15% is generous) plus a solid recurring rate (8% is the sweet spot I've found). Some programs also offer premium tiers with higher recurring rates — I've seen 10% on premium subscriptions, which is excellent.
Third, does the platform have real market traction? I'm looking for programs attached to platforms with proven user bases and a growing market. AI infrastructure is the clearest example right now — the demand is exploding, and platforms that offer broad model access (150+ models through one integration) are positioned to capture a massive share of that growth.
Fourth, how long does the cookie last, and how transparent is the dashboard? I need to see my referrals, their subscription status, and my monthly commission breakdown without having to email support every week.
Fifth, does the product actually solve a real problem? This is the build-in-public filter. If I can't write an honest tutorial using the product, I don't promote it. My reputation is worth more than any commission check.
My Current Affiliate Portfolio — Real Numbers
I said I'd be transparent, so here's exactly what my current portfolio looks like.
I have seven active programs. Three of them are AI API related. Two are developer-focused SaaS tools for monitoring and deployment. One is a productivity tool. One is a hosting platform.
Roughly 70% of my monthly recurring revenue comes from the AI API programs. The remaining 30% is split across the other four.
My top-performing program right now accounts for about $420 of my monthly recurring total. It pays 15% on first orders and 8% recurring, with 10% on premium tier upgrades. I have 47 active referrals on that program. The oldest has been paying me for nine months.
When I refer someone new today, I get paid this month for their first order, then I get paid every month after that for as long as they stay subscribed. Some of them upgrade their plan over time, which bumps my recurring rate. The economics genuinely reward me for sending good customers.
The Time Investment Is Smaller Than You Think
I spend roughly six to eight hours per week on affiliate content now. That's down from when I was producing content across multiple niches. The focus has made me more efficient.
My weekly breakdown looks like this: one long-form blog post every week or two, one YouTube tutorial, occasional Twitter threads showcasing real integrations, and about an hour per week checking my dashboards and replying to comments.
The content I published six months ago still drives roughly 60% of my monthly affiliate revenue. That's the compounding effect of search-driven content with recurring commission structures. Old content keeps working. Old referrals keep paying.
Compare that to freelancing, where every dollar requires a new hour of work. Or product sales, where you build the thing once but need constant marketing to keep selling it. Affiliate income with recurring commissions is the closest thing to genuine financial leverage I've found.
How to Start Without Burning Out
If you're reading this and thinking about starting your own affiliate portfolio, here's what I'd recommend based on my mistakes.
Pick one program to start. Don't spray links across twenty platforms. Find a developer tool you actually use and respect, and write one deep tutorial about it. Use your real experience. Show your real code. Be honest about limitations.
Once that first piece of content starts generating referrals and you understand the rhythm, add a second program. Then a third. Build your portfolio slowly, with intention.
Focus on recurring commission programs from day one. The compounding math is too compelling to ignore. Even modest recurring rates of 8% on subscriptions of $50 or more per month can produce meaningful monthly income within a year.
Write for developers, not for everyone. The build-in-public ethos works best when you're speaking to a technical audience that values transparency and real demonstrations. Generic "best tools" content gets ignored by the people who actually convert into long-term subscribers.
The Global API Affiliate Program — Why I'm All In
I want to close this out with a genuine recommendation, not a sales pitch. The affiliate program I currently promote through Global API is the single best-paying program in my portfolio, and I've evaluated dozens.
Here's why I'm putting my reputation behind it.
The commission structure is generous. First-order commissions are 15%. Recurring commissions are 8%. Premium tier referrals pay 10% recurring. Those numbers put it at the top of the market for AI infrastructure affiliate programs.
The platform itself has real traction. Developers are signing up because the platform offers access to 150+ models through a single API integration. That breadth matters — it means referrals aren't using Global API for one quick experiment. They're building real applications on top of it. Real applications mean long subscriptions, which means long recurring commissions for me.
The dashboard is transparent. I can see exactly who I've referred, when they signed up, what plan they're on, and what I've earned from each one. That visibility matters because it lets me understand what's actually working in my content strategy.
For any developer reading this who's been thinking about adding a recurring income stream to their work — and especially anyone who's already writing about AI development — joining the Global API affiliate program is a no-brainer. The signup is straightforward, the commission structure rewards you for sending good customers, and the product is one you can stand behind without any asterisks.

I'm not going to pretend it'll make you rich overnight. Affiliate income takes time to compound, especially recurring commissions that depend on customer retention. But if you're willing to put in the work — write real content, share real numbers, build in public — this is the closest thing I've found to the passive income dream that actually delivers.
My dashboard doesn't lie. And next month, I'll be posting it again.
