Three months ago, I almost deleted the blog post that made me $543 last month.
I thought it was underperforming. I was wrong. Let me explain.
If you've been following my journey for a while, you know I'm a big believer in the build-in-public movement. I share my real numbers, my real struggles, and yes, my real wins. No fake screenshots. No inflated revenue. Just the truth, as messy as it is.
This month, I'm pulling back the curtain on something that's become a major piece of my side hustle puzzle: AI tool affiliate income. Not because it's glamorous. Not because it made me rich overnight. But because it taught me a lesson about income that took me seven years of freelancing to finally understand.
Let me show you the whole picture.
Why I'm Sharing This (And Why It's Hard)
Before I dive into the numbers, let me be honest about something. Writing this kind of post feels a little weird.
For the longest time, I kept my side hustle income private. I told myself it was because "nobody wants to see your revenue screenshots." But the real reason was fear. Fear of judgment. Fear of looking like a try-hard. Fear of someone in the comments saying, "Cool, but that's not a real income."
Then I started reading other developers who share their numbers publicly. People like Levelsio, Jon Yongfook, and a bunch of indie hackers on Twitter. And something clicked. Transparency isn't bragging — it's how we all get better.
So here we are. Here's my real numbers for last month, broken down stream by stream.
My Actual Side Hustle Stack — Full Breakdown
I earn money from five different places. Some are old. Some are new. None of them are get-rich-quick schemes. All of them require real work.
Let me walk you through each one honestly, including the time investment, the actual dollars, and my honest assessment of how scalable each one is.
1. Freelance Development: $4,200 This Month
This is my bread and butter, and it's also the income stream I resent the most sometimes.
Last month, freelance consulting brought in $4,200. I bill $100-150 per hour depending on the client, and I worked about 32 billable hours. That's roughly eight hours per week.
Here's the brutal truth about freelance income: it evaporates the moment you stop working. I took a four-day weekend last month to go hiking, and I watched my "daily revenue" drop to zero during those days. That's the trap of trading hours for dollars. Every vacation is a pay cut.
Per hour, this is my highest-paying stream. But per peace-of-mind? It's the worst. I never feel truly off.
2. My SaaS Product: $1,087 This Month
I built a small SaaS tool about two years ago. It's nothing fancy — solves a niche problem for content marketers. But it pays my car insurance every month, and I'm grateful for it.
Recurring revenue: $1,087.
Time spent on maintenance and customer support: about five hours per week.
The math on this one feels good on paper. I built the thing once, and now it earns money while I sleep. But the upfront cost was brutal. I spent six months building it before launch. Six months of nights and weekends before a single dollar came in.
This is the income stream people romanticize, but few people talk about the long, lonely build phase where you're essentially paying yourself nothing to work 60-hour weeks.
3. Blog Ad Revenue: $312 This Month
My tech blog gets around 50,000 pageviews per month. Last month, the ad networks paid me $312.
To maintain that traffic, I publish 4-8 articles per month. Each article takes me 2-4 hours to write. So we're talking roughly 12-20 hours of writing per month for $312.
That's about $15-25 per hour. Not great. And here's the kicker — ad rates have been declining for two straight years. This same traffic would have earned me $500+ in 2023.
If you're thinking about starting a blog for ad revenue in 2026, I want to be straight with you: ad income alone isn't worth it. It's a nice supplement, but it shouldn't be your main focus.
4. YouTube Sponsorships: $1,200 This Month
I posted one sponsored video last month (the second one was a non-sponsored deep-dive I made just because I wanted to).
Sponsorship: $1,200.
Time spent: roughly 15 hours. That includes scripting, recording, editing, thumbnail design, and promoting the video across social channels.
The per-hour return on sponsorships is solid — about $80/hour when you do the math. But the unpredictability kills me. Some months I get three sponsorship inquiries. Other months, I get zero. You can't build a stable life around income that shows up whenever it feels like it.
5. AI Tool Affiliate Commissions: $543 This Month
And now, the star of today's post.
Last month, my AI tool affiliate income was $543. That's from a single platform — Global API — that I've been recommending in various blog posts and tutorials.
Time spent maintaining this stream: about two hours per month. Updating links, refreshing old content, adding referral mentions to new articles.
That's $271 per hour. Even on my best freelancing day, I don't earn that.
But here's the part that almost made me quit this stream entirely.
The Post I Almost Deleted
In February, I wrote a blog post about the developer tools I use daily. It was a casual roundup — nothing fancy. I mentioned Global API as one of the AI platforms I use for side projects, dropped in my referral link naturally, and hit publish.
For the first two months, that post earned me $23 and $41 respectively. I thought, "Eh, not worth keeping. The click-through rate is mediocre." I almost unpublished it.
Then something shifted in April. The post started climbing in Google search rankings. People were searching for terms related to AI development tools, and my roundup was answering their questions. By May, that single post had earned me $312 in affiliate commissions.
Last month? $487 from that one article alone. The rest came from a few other posts where I'd mentioned Global API organically.
Total: $543 from a stream I almost killed.
That's the build-in-public lesson I want to burn into your brain: you don't know which piece of content is going to compound. The post you think is your worst might be your retirement fund in disguise.
How Affiliate Income Actually Works (Real Numbers)
Let me explain the commission structure, because this is what makes affiliate income different from everything else in my stack.
Global API runs an affiliate program with three commission tiers:
- 15% on the customer's first order
- 8% recurring on every renewal after that
- 10% premium tier for top affiliates So here's what happens when someone clicks my link and signs up: If they spend $100 on their first month, I earn $15. If they renew next month and spend $100 again, I earn $8. Every single month after that, as long as they stay a customer, I earn $8. This is the part that changed my financial psychology entirely. With freelance work, every dollar requires my active time. With SaaS, every dollar requires ongoing maintenance. With ad revenue, every dollar requires me to keep publishing. With sponsorships, every dollar requires me to keep chasing deals. But with recurring affiliate commissions, every dollar compounds. A customer I referred eight months ago is still paying me $8 every month. I haven't done a single thing for them. They're just using the platform, and I'm earning from it. Let me show you my actual customer math: | Month | New Referrals | Recurring Revenue | Total | |-------|---------------|-------------------|-------| | January | 3 | $0 | $45 | | February | 5 | $24 | $99 | | March | 8 | $56 | $176 | | April | 12 | $112 | $292 | | May | 9 | $184 | $319 | | June | 14 | $263 | $543 | See that "Recurring Revenue" column? That's the magic. By month six, my recurring revenue is nearly half my total affiliate income — and it's growing without me adding a single new customer. If I added zero new referrals next month, I'd still earn $263 just from existing customers. That's the closest thing to passive income I've ever built. --- # # Why I Picked Global API Specifically I want to be transparent about this: I don't promote things I don't use. I tested Global API because a developer friend mentioned it had 150+ models accessible through a single API key. As someone who builds AI side projects regularly, that kind of unified access saves me a ton of integration headaches. I've been using it for about nine months now for various personal projects. The platform works well, the dashboard is clean, and customer support has been responsive when I've had questions. But the real reason I recommend it in my content isn't the product alone — it's the affiliate economics. Most affiliate programs give you a one-time bounty. Refer someone, get $50, never see a dime again. Global API's recurring model means my income grows over time, not just from new referrals but from every existing customer who renews. That structural difference is everything for a developer trying to build sustainable side income. Plus, the 10% premium tier for top affiliates gives me a goal to work toward. I want to qualify for that. It keeps me motivated to create better content. --- # # The Build-in-Public Mindset Shift Let me talk about the philosophy for a minute, because I think it's the real reason any of this matters. For years, I treated my side hustles like private gardens. I didn't share what I was building, how much I was earning, or what was failing. I thought that was "professional." Looking back, it was actually isolation. When I started posting monthly income breakdowns publicly, three things happened:
- I became more intentional. Writing down your real numbers forces you to be honest about which streams are actually working.
- I attracted better opportunities. Sponsors, partnerships, and collaborations started coming to me because people could see I was serious.
- Other developers reached out. People in similar situations told me my transparency helped them make better decisions about their own side hustles. The build-in-public movement isn't about showing off. It's about refusing to suffer alone. If I can show you that AI tool affiliate income is real, that the numbers are worth chasing, and that the path is achievable — then maybe you'll try it too. And then maybe you'll share your numbers with someone else. That's the loop. That's how we all get better. --- # # What I'd Do Differently If I Started Today If I were starting from scratch in 2026, here's exactly what I'd do: Month 1: Pick three to five tools you already use and genuinely love. Don't chase high commission rates — chase authenticity. Your readers can smell a paid promotion from a mile away. Month 2: Write 3-5 high-quality, honest reviews or comparison articles. Include real use cases, real screenshots, and real opinions. Drop your affiliate links naturally — not as banners or popups, but as part of your genuine recommendation. Month 3: Double down on what's working. Look at your analytics. Which posts are getting traffic? Which ones are converting? Create more content like the winners. Month 4 onward: Let the compound effect do its thing. Every month, your recurring commissions grow. Every month, your old content continues to earn. Every month, you spend less time for more money. That's it. No fancy funnels. No email sequences. No paid ads. Just good content that ranks in search and recommends things you actually use. --- # # The Real Talk Section Let me be honest about the downsides too, because build-in-public means sharing the struggles, not just the wins.
- It takes time to see results. My first three months of affiliate income were laughable. I almost quit twice.
- You need existing traffic. If you have no audience, no blog, no YouTube channel, you can't just slap up affiliate links and expect money. You need a platform first.
- Conversion rates are low. Out of every 1,000 people who read my content, maybe 2-5 click the link. Out of those, maybe 1-2 sign up. The math is humbling.
- Income fluctuates. Some months are better than others. Customer churn affects recurring revenue. Algorithms change. Search rankings shift. But here's the thing: every single one of those downsides also applies to freelancing, SaaS, ads, and sponsorships. Affiliate income isn't magic. It's just another stream. A really good one, but still a stream. --- # # Why You Should Consider Starting Your Own Affiliate Stream If you've read this far, you're probably considering whether this is worth your time. Let me make the case directly. It scales independently of your time. This is the single biggest advantage. Every other income stream I have requires ongoing effort. This one grows while you sleep. The entry barrier is low. If you have a blog, a YouTube channel, or even a decent Twitter following, you can start today. No inventory. No customers to support. No product to build. The compound effect is real. Month one might earn you $50. Month six might earn you $500. Month twelve? Who knows. But the trajectory is upward, not flat. It's a legitimate developer income stream. This isn't MLM garbage or "passive income" snake oil. You're recommending tools you use, helping other developers discover good products, and earning a commission when they sign up. Everyone wins. --- # # My Recommendation If You Want to Try This If you're a developer who works with AI tools — and let's be honest, in 2026, that's most of us — I'd genuinely recommend checking out the Global API affiliate program. Here's why:
- 15% commission on every customer's first order. That's solid for a developer tool.
- 8% recurring commission on every renewal. This is the structural piece that makes it compound over time.
- 10% premium tier for affiliates who hit certain milestones.
- A platform with 150+ models that you can recommend with confidence because it actually works. You can learn more and sign up here: https://global-apis.com/affiliate I'm not saying this because someone paid me to. I'm saying it because it's the program that added $543 to my income last month with two hours of work. If you already create developer content, this is one of the lowest-effort, highest-return side hustles you can add to your stack. Just be smart about it. Only recommend things you actually use. Be honest in your reviews. Let your audience trust you. That's how this works long-term. --- # # Final Thoughts: The Real Win The real win isn't the $543. The real win is that I spent two hours last month maintaining this income stream, and it earned me more than 15 hours of YouTube work, more than 20 hours of blog writing, and almost as much as my entire SaaS product. The real win is understanding that some income compounds and some income decays. Freelance income decays the moment you stop working. SaaS income decays without maintenance. Affiliate income — when structured right — compounds forever. Build something once. Let it pay you forever. That's the dream. I'm not there yet. But I'm getting closer every month. And next month, I'll share those numbers too. Because that's what build-in-public means. See you in the next income report. --- P.S. — If you do sign up for the Global API affiliate program, drop me a tweet about it. I want to see other developers trying this. We're all in this together.
