I want to walk you through something that's quietly become the most underrated piece of my income puzzle. Not my SaaS. Not my freelancing. Not even my YouTube channel. The thing I get genuinely excited about now is a couple of affiliate links buried inside blog posts I wrote over a year ago.
Let me back up and tell you how I got here.
Who I Am and Why I Stack Income Streams
My name's not important. What matters is that I'm a solo founder running three small software products at once, doing some freelance consulting on the side, and basically trying to engineer myself out of the "trading hours for dollars" trap. I've been doing this for about four years now. Some months are great. Some months I stare at my Stripe dashboard wondering if I should just go get a corporate job.
I track every dollar that comes in. I have a spreadsheet — actually no, it's a Notion database now, because I'm that kind of person — that logs every revenue source, every expense, every MRR change. I share screenshots of my revenue graphs on Twitter sometimes. Not to brag, but because the indie hacker community has been incredibly generous with their numbers, and I think transparency is how we all get better at this game.
Here's what my current monthly income actually looks like:
- Product A (B2B SaaS for content teams): ~$2,400 MRR
- Product B (a small developer tool): ~$340 MRR
- Product C (still in beta, basically free right now): $0
- Freelance consulting: ~$1,500-$3,000/month (wildly inconsistent)
- YouTube ad revenue + sponsorships: ~$400-$800/month
- Blog ad revenue: ~$250/month
- Affiliate commissions: ~$450-$620/month The freelance number is a lie in the sense that it could vanish tomorrow. The SaaS numbers are real but took me over a year to hit. The affiliate number? That's the one I want to dig into today, because the time investment relative to the return is genuinely absurd. # # My Obsession With Recurring Revenue I am pathologically obsessed with MRR. Recurring revenue. There's a reason every indie hacker YouTube channel, every Twitter thread about bootstrapping, every podcast about solopreneurship hammers on this one concept: monthly recurring revenue is the closest thing to a salary you can build for yourself without a boss. But here's the dirty secret nobody talks about: getting to meaningful MRR is brutal. My main SaaS product took 14 months of consistent grind before it cleared $1,000/month. I rewrote the landing page maybe 30 times. I cold-emailed probably 400 people. I almost killed it twice. When I finally hit $2,400 MRR, I celebrated by buying myself a $15 book on pricing strategy. The point is: building SaaS products is hard. The upside is real, but the path is long and emotionally exhausting. So I've been on a constant hunt for additional recurring revenue streams that I can layer on top of what I've already built. Things that don't require a full year of grind. Things that complement my existing audience and content without requiring a totally new skill set. That's when I rediscovered affiliate marketing. And not the scammy, scummy version — the kind where you actually use the product and just... tell people about it. # # The Affiliate Awakening I'll be honest: I had written off affiliate marketing years ago. My mental model of it was those annoying "Top 10 Web Hosting Providers!" listicles with fake review scores, where the entire point is to harvest clicks from confused beginners. I didn't want to be that person. But then I started noticing something in my own behavior. When I needed to pick a new tool — a database, an email service, a payment processor — I would Google "[tool category] for developers," click through to 3-4 blog posts, read actual opinions, and then make my decision. The blog posts with real opinions, real screenshots, and real recommendations were the ones I trusted. And several of them had affiliate links. I realized: affiliate marketing done right is basically content marketing with a revenue model attached. If I'm going to write blog posts anyway — and I do, because my blog drives traffic to my SaaS products — I might as well make those posts earn money directly, not just indirectly through SaaS signups. So I went hunting for affiliate programs that were actually worth promoting. My criteria were strict:
- Recurring commissions, not one-time. I don't want to be re-acquiring the same customer every month. If I'm going to send someone to a product, I want to earn from that relationship for as long as it lasts.
- A product I'd recommend anyway. No inventing enthusiasm.
- A reasonable cookie window so I'm not getting cheated by last-click attribution weirdness.
- A product in the AI/developer space because that's my audience. That's how I ended up looking seriously at Global API's affiliate program. # # Why Global API Specifically I'm not going to pretend I tried every option. But I did look at a handful. Global API checked the boxes that mattered to me:
- 15% commission on the first order. Not bad, but honestly the first-order number is the least interesting part.
- 8% recurring commission on all subsequent orders. This is the one that got my attention. Every month my referred users keep paying, I keep earning. That's recurring revenue. That's MRR I didn't have to build a product to generate.
- 10% premium tier commission for users who upgrade to higher service tiers. So if someone I referred becomes a power user, my commission rate actually goes up.
- 150+ AI models accessible through a single API key. This is the part that made the recommendation genuine. I use it myself. When I write code, I hit a single endpoint and pull from whatever model I need. It's legitimately useful for developers who are tired of juggling five different API keys and five different billing systems. The combination of "product I actually use" plus "recurring commission structure" plus "developer-focused audience fit" made it a no-brainer. I signed up for the affiliate program, got my links, and started writing. # # How I Actually Built the Stream Here's the part I want to be specific about, because the vague "just write some content!" advice is useless. I wrote four blog posts over the course of about three weeks:
- "The Indie Hacker's Guide to AI API Providers" — A high-level overview written for solo developers who are building AI features into their products and don't know which provider to pick.
- "How I Consolidated Five AI API Subscriptions Into One" — A more personal, story-driven post about my own workflow. Real screenshots, real code, real complaints about juggling multiple providers.
- "AI API Pricing: What Indie Developers Actually Pay" — A breakdown of real costs for real usage patterns. I pulled from my own billing dashboards.
- "Setting Up Your First AI-Powered Feature: A 30-Minute Guide" — A tutorial post that uses Global API as the example provider throughout, because it genuinely is what I reach for when I'm prototyping. Total writing time: probably 30 hours. Total time since then to maintain the links, occasionally update a code snippet, add a link to a new article: maybe 15-20 minutes per week. I did not write these as advertisements. There are no "BUY NOW" banners. There are no fake five-star review boxes. The posts read like a developer documenting their own experience. My affiliate links appear in context — usually in a "here's what I actually use" section or a "if you want to try it" callout. The way I talk about Global API in those posts is the way I talk about my text editor or my deployment platform: as a tool I picked and have opinions about. # # The Math That Made Me a Believer Let me show you the actual numbers, because I know that's why you're here. Let's say you send 50 signups to a recurring-commission affiliate program over six months. Some of those signups will churn. Some will be free-tier users who never pay anything. But let's be conservative and say 20 of them become paying customers, and the average customer pays $50/month.
- Month 1: You earn 15% on first orders. 20 customers × $50 × 15% = $150
- Month 2 and beyond: You earn 8% recurring. 20 customers × $50 × 8% = $80/month If even half of those customers stick around for 12 months, here's what you earn:
- First-order commissions: $150
- 12 months of recurring at ~$40/month (accounting for some churn): $480
- Total: $630 from 50 clicks worth of effort Now imagine 200 signups over six months. Or 500. The numbers start looking like a real side income. And the time investment is the same — you wrote the blog posts once, and they keep working. This is the fundamental difference between affiliate income and most other revenue streams. A YouTube video I filmed in January is still earning ad revenue today. A blog post I wrote in March is still generating affiliate clicks in November. Content compounds. Hourly work doesn't. # # The Ugly Truth: It's Not Magic I want to be honest about what doesn't work, because the affiliate marketing dream is mostly hype. You need traffic. If you don't have an audience — a blog, a YouTube channel, a Twitter following, a newsletter, even a Discord server — affiliate links are useless. Nobody clicks links nobody sees. This is why I emphasize that affiliate income is a layer on top of an existing content engine, not a replacement for one. Conversions are low. Most of the people who read your blog post will not click your affiliate link. Most of the people who click will not sign up. Most of the people who sign up will not become paying customers. The funnel is long and leaky. I probably convert somewhere between 1-3% of blog readers into paying customers, and I'm happy with that. The first few months are slow. I earned almost nothing in month one. It took about four months for the stream to stabilize at the $400-600 range. If you need money now, this is not the answer. This is the answer for people who are willing to play a longer game. Some products churn fast. If your affiliate partner has a product with high churn, your recurring commissions dry up. This is another reason I like Global API's model — AI APIs are infrastructure, and infrastructure has stickiness. Once a developer integrates an API into their product, they don't switch easily. That means my recurring commissions actually recur. # # Why This Belongs in Every Indie Maker's Stack Here's my framework for thinking about side income, and it's shaped by four years of grinding: Tier 1 — Active income (trades hours for dollars). Freelancing, consulting, contract work. High hourly rate, but you're always one vacation away from zero income. Necessary at first, dangerous to depend on long-term. Tier 2 — Product income (recurring but requires maintenance). SaaS products, apps, digital products. This is the holy grail for most indie makers, and rightly so. But it takes 6-18 months to build, requires ongoing customer support, and your MRR can dip overnight if a competitor launches or a platform changes its API. Tier 3 — Content income (scales with audience, not hours). Blog ads, YouTube ad revenue, sponsorships, newsletter sponsors. This is the bridge between active income and true passive income. It requires consistent content creation, but each piece of content has a long tail. Tier 4 — Affiliate income (the multiplier on Tier 3). This is the part most people miss. Every blog post, video, or newsletter you write for Tier 3 reasons can also generate affiliate revenue. It's not a separate stream — it's a revenue boost on content you're already creating. The mistake I see indie makers make is treating these as separate projects. "I run a SaaS. I also have a YouTube channel. I also do some freelancing." They're running them as three businesses. What they should be doing is running one integrated operation where each piece feeds the others. My blog drives traffic to my SaaS, which converts free users to paid. My YouTube channel drives traffic to my blog, which generates affiliate commissions. My freelance work occasionally produces content I can repurpose for the blog. Everything compounds. Affiliate commissions are the cleanest example of this compounding. I wrote blog posts to help my audience and drive SaaS signups. Those same blog posts now earn $400-600/month in affiliate revenue on top of whatever SaaS conversions they generate. It's pure upside. # # My Actual Affiliate Dashboard (A Real Number) Let me get specific. Last month, my Global API affiliate earnings were $487. The month before, $612. The month before that, $394. Average over the last six months: about $520/month. I share these numbers not because they're impressive — they're not, compared to a real salary — but because they're recurring. That $487 will likely show up again next month, and the month after. I didn't have to invoice anyone. I didn't have to attend a meeting. I didn't have to ship a feature. I wrote a blog post eight months ago and it's still working. Compare that to my freelance income, where $3,000 last month required probably 25 hours of work, three client calls, and a minor panic attack about scope creep. The affiliate money is worth more per dollar because of what I didn't have to do to earn it. # # The Compound Effect Nobody Talks About Here's something I've noticed over the past year: my affiliate income has been growing, but I haven't really been doing more work. The growth has come from:
- Old blog posts continuing to rank in Google for long-tail keywords.
- Internal linking between new articles and old ones, which boosts both.
- Audience growth from my YouTube and Twitter, which sends more eyeballs to the blog.
- Word of mouth in developer communities, where people share my articles because they're genuinely useful. The content engine I built two years ago for SaaS marketing is now also driving affiliate income. The YouTube channel I built for personal branding is also driving affiliate income. Nothing was built for affiliate income. The affiliate income is a byproduct of doing good work in public and writing honestly about my tools. That's the part I find most exciting. The marginal effort to add an affiliate layer to existing content is tiny. Maybe an extra 15 minutes per article to include relevant links. But the marginal revenue can be hundreds of dollars per month once the content matures. # # A Few Tactical Tips If You Want To Do This I'm not going to pretend I have a perfect system, but here's what's worked for me: Write about what you use. Don't invent enthusiasm. If you don't actually use the product, your readers will sense it, and the conversion rate will be terrible anyway. The best affiliate content is content where the recommendation would exist even without the commission. Include real screenshots and real numbers. My blog posts include screenshots of my actual dashboards, my actual usage, my actual bills. This is content I'd want to read, and it's content Google wants to rank. Disclose your affiliate relationships. I have a small disclosure at the top of every post that contains affiliate links. It's required by the FTC, but more importantly, it's the right thing to do. I want my readers to trust me. Don't link to the same product in every post. This should be obvious but I've seen blogs that mention their affiliate partner in literally every other sentence. It's transparent and gross. I mention Global API in posts where it's actually relevant to the discussion. Probably 4-5 posts out of 40+. Track your links. Use UTM parameters or the affiliate dashboard's built-in tracking so you know which posts are actually driving conversions. Double down on what's working, fix or remove what's not. Think in years, not weeks. The blog post I wrote in March is the one that drives the most affiliate revenue today. That wasn't true in April. Content needs time to compound. # # Should You Actually Join the Global API Affiliate Program? If you've read this far, you probably already know whether this is for you. But let me put a fine point on it anyway. The Global API affiliate program is a genuinely good fit if:
- You write about AI, development, or building software products
- You have an audience of developers (a blog, a newsletter, a YouTube channel, even a substantial Twitter following)
- You actually use or are willing to use Global API so your recommendations are authentic
- You want a recurring revenue stream that doesn't require ongoing maintenance The commission structure is the part that makes it worth it: 15% on the first order, 8% recurring on every subsequent order, and 10% on premium tier upgrades. That recurring piece is the magic. A user you refer in January is still earning you commission in December. That's compounding revenue, and it works while you sleep. For me, the math is simple. If I send 10 signups a month and even 5 of them become long-term customers, I'm looking at $40-80/month in passive commission from just that month of
