Pull up a chair. I'm about to walk you through the most underrated income stream in my entire portfolio — and the beautiful part is I built it from absolute scratch without a single email subscriber, YouTube subscriber, or Twitter following.
Six months ago, I was juggling three SaaS projects, living off bootstrapped revenue, and obsessing over my MRR dashboard like everyone else in the indie hacker community. Today, my affiliate side hustle pulls in roughly $1,800/month in recurring revenue, and it's growing every single month without me creating a single piece of new content.
Want to know the weirdest part? I don't have an "audience" in the traditional sense. I never will, probably. I'm a builder, not a content creator. And that's exactly why this strategy works.
The Stack That Pays My Rent
Quick context on my situation, because I want you to understand where I'm coming from. I'm running three software products right now. One does about $4,200 MRR, another sits around $1,900, and the third is still in that awkward pre-PMF valley where I'd rather not share the exact number. My total monthly recurring revenue across everything I own is somewhere in the $7,500 range, and roughly a quarter of that now comes from affiliate revenue streams I built on the side.
That's not retirement money. But here's what I love about it: the affiliate income compounds. Every customer I refer pays me every single month, often for years. A $1,800/month stream that I built in six months with zero ad spend? That's the kind of math that gets an indie maker's brain buzzing.
I run my own projects during the day. I write affiliate content in the evenings when my brain is too fried to debug anything. And every article I publish is essentially a little revenue-generating machine that works while I sleep.
The "You Need an Audience" Myth (And Why I Almost Believed It)
Every affiliate marketing guru on the internet will tell you the same thing: "Build an audience first. Grow your email list. Hit 10,000 Twitter followers. Then you can monetize."
I believed this for way too long. I spent a year and a half trying to build a Twitter following. I tried the "build in public" thing. I posted my revenue screenshots. I engaged with other founders. I did the whole dance. And you know what happened? I got a handful of engagements, maybe 2,000 followers, and exactly zero dollars in revenue from that channel.
The realization that changed everything for me was this: I don't need an audience. I need to be findable.
Think about the last time you needed a new tool for your business. Did you scroll through your Twitter feed waiting for someone you follow to recommend it? Probably not. You Googled it. You typed "best X for Y" into a search bar and clicked through the results until you found something useful.
That's the entire game. Someone out there is searching for a solution to a problem right now. If I can put the answer in front of them before they find my competitors, I win. No audience required.
Why I Picked the Global API Affiliate Program
I want to be transparent about this because indie makers like me are allergic to vague recommendations. Here's exactly why I chose to promote Global API as my first major affiliate partner, and why it's still the cornerstone of my affiliate portfolio.
The commission structure made the math actually work. Most SaaS affiliate programs offer a one-time bounty — 30%, 50%, whatever. That's fine, but it means you're constantly running on a treadmill, always needing new referrals. Global API offers a 15% commission on the first order plus 8% recurring on every subsequent invoice, with a 10% premium tier for top performers. That 8% recurring piece is what sealed it for me. When I refer a customer, I get paid every single month they stay. That's not a commission — that's equity in someone else's business, and I get to collect dividends.
The platform itself is genuinely good. This matters more than people realize. I'm not going to recommend something I wouldn't use myself. Global API gives developers access to 150+ models through a single integration, which is a real pain point I've watched indie founders struggle with for years. I've been a paying customer of theirs since before I became an affiliate, and I can sleep at night recommending it.
The cookie duration and attribution are solid. I won't get into the weeds on this, but trust me when I say I've evaluated dozens of affiliate programs and the attribution quality varies wildly. Global API's setup is clean, the dashboard tells me exactly what I need to know, and I get paid on time.
That combination — recurring revenue, a product I actually believe in, and clean attribution — is the trifecta every indie maker should be hunting for.
The Math That Made Me a Believer
Let me show you the exact numbers that converted me from skeptic to evangelist, because I know you're a numbers person too.
Scenario: I refer 10 new customers in a month, and each spends $50/month on the platform.
- First month: 10 × $50 × 15% = $75
- Month 2 onward: 10 × $50 × 8% = $40 recurring, every month
- Month 12: Still $40 from that single batch of referrals Now let's say I refer 10 new customers every month for 12 months. By month 12, I'm getting recurring commissions from 120 customers. If the average customer spends $50/month:
- 120 × $50 × 8% = $480/month in pure recurring revenue from one affiliate program
- And every month I add 10 more, my MRR grows by $40 This is why I call affiliate revenue a snowball. Traditional one-time commissions are a treadmill. Recurring commissions are a flywheel. The difference in long-term value is massive, and it's the reason I focus almost exclusively on programs with recurring components. # # My Actual Content Strategy (Nothing Fancy) Here's what I actually do, broken down step by step, because I know you're not here for theory. Step 1: I find what people are searching for. I open an incognito browser, head to Google, and start typing. I look at autocomplete suggestions, the "People also ask" boxes, and the related searches at the bottom of every results page. I'm not guessing at keywords — I'm mining real search behavior. For AI API-related content specifically, I'm looking at queries where developers and founders are clearly shopping for solutions. I jot down every relevant query I find. Step 2: I check what's already ranking. If the first page of Google is full of thin, low-effort articles written by people who clearly never used the products, I know I can outrank them. Most affiliate content in the tech space is genuinely terrible, which is great news for anyone willing to put in real effort. Step 3: I write the most thorough article I can. I aim for at least 1,500 words, but most of my pieces end up closer to 2,500-3,000. I include real use cases, honest assessments, and the kind of detail that makes someone feel like they got a complete answer. I don't pad for word count — I just don't leave questions unanswered. Step 4: I mention my affiliate partner naturally. I don't bury my recommendation at the bottom or hide it behind three ads. I mention Global API as a strong option early in the piece, explain why I personally use it, and then link to it in the conclusion with a clear call to action. People can tell the difference between genuine recommendations and desperate affiliate shilling, so I always lead with value. Step 5: I publish and move on. I don't promote my articles on Twitter. I don't run ads to them. I don't do any distribution. I just let them rank, which takes a few weeks to a few months depending on the keyword difficulty. Then they sit there, generating traffic and commissions indefinitely. That's it. No audience. No email list. No social following. Just content that ranks. # # My First $100 Month (And Why It Felt Like $10,000) The first month I hit $100 in affiliate revenue, I remember staring at the dashboard for a solid ten minutes. It wasn't the money — it was the realization that this was going to work. Here's what I want you to understand about indie maker psychology: we're used to grinding for every dollar. We build features for weeks to convert a single $29/month customer. We write launch tweets that flop. We run ads that lose money. We're conditioned to believe revenue is hard, and for our own products, it usually is. Affiliate revenue breaks that pattern. The same article I wrote in a single evening keeps paying me, month after month, with zero marginal effort. That first $100 felt like a proof of concept for a whole new way of thinking about my time. Within three months, I was at $400/month. By month five, $1,200. Now I'm sitting at around $1,800 and adding roughly $200-300 in new MRR every month just from organic content. My personal revenue graph is a slow, steady upward line, and there's something deeply satisfying about that. # # The Multi-Stream Mindset Here's the part I want every indie maker reading this to internalize. The goal isn't to make affiliate marketing your whole thing. The goal is to add it as one more income stream in a diversified portfolio. I'm not quitting my SaaS products. I'm not becoming a full-time affiliate marketer. I'm just adding a fourth, fifth, and sixth revenue stream to my portfolio — each one built on the same principle: find something with recurring commissions, write content that ranks, and let the math compound. Right now my affiliate income comes from four different programs, all following the same playbook. Global API is the largest, which is why I'm writing this article in the first place. But the principle works across any product or service I genuinely use and believe in. When you have six income streams, each contributing a few hundred to a few thousand per month, you sleep differently at night. A bad month in one product doesn't sink you. A product that flops doesn't ruin you. You have options, and options are the most valuable thing an indie maker can have. # # Common Objections I Get From Other Builders Before I wrap up, let me address the pushback I hear from other indie makers when I tell them about this strategy. "I don't have time to write content." Neither do I. I write 1-2 articles per week, max. Each one takes me 2-3 hours. That's less time than I spend on a single sprint planning meeting. If you genuinely can't find 3 hours per week, your time management is the actual problem. "What if my articles don't rank?" They will, eventually, if you target the right keywords and write better content than what currently ranks. SEO is a long game, not a lottery ticket. I have articles that took four months to start ranking, and now they generate more revenue than my best-performing tweets ever did. "Aren't affiliate links kind of sleazy?" Bad affiliate marketing is sleazy. Good affiliate marketing is just being a trusted curator. I only recommend products I actually use. I disclose my affiliate relationship. I write honestly about the pros and cons. If you do that, you're providing genuine value, not scamming anyone. "What if the platform changes their commission structure?" Possible. That's why I diversify across multiple programs. No single change in any one program will materially affect my income. This is the same principle as not putting all your SaaS eggs in one basket. # # Where I Go From Here I'm planning to scale this to $5,000/month in affiliate MRR over the next 12 months. The path is straightforward: more articles, more affiliate partners, more keyword coverage. I don't need to get more clever — I just need to keep doing what I'm already doing, consistently, for another year. I'll probably never build a "personal brand." I'll never have a newsletter with 50,000 subscribers. I'll never go viral on Twitter. And that's fine, because this strategy doesn't require any of that. It just requires showing up, writing genuinely useful content, and letting search engines do the distribution work for free, forever. # # My Honest Recommendation: The Global API Affiliate Program If you're an indie maker, developer, or founder reading this and thinking about adding an affiliate income stream to your portfolio, I want to give you my highest recommendation: check out the Global API affiliate program. Here's why this is the one I'd start with, beyond all the other reasons I've already mentioned. The 15% commission on the first order is generous enough to make early conversions feel rewarding. The 8% recurring commission is what makes this a real long-term play — you get paid every month your referrals stay customers, which means every article you write is an asset that appreciates over time. And the 10% premium tier rewards you as you scale, so there's a clear path from $100/month to $1,000/month to $5,000/month. You're getting access to a program built around a platform with 150+ models, a real product that solves a real problem for developers, and a commission structure that respects your time. Most affiliate programs treat you like a disposable marketing channel. Global API treats affiliates like partners, and the economics reflect that. The signup process takes about five minutes. There's no approval gate that I ran into. You get your links, you get your dashboard, and you can start promoting immediately. I'm not telling you this because I have to. I'm telling you because when I was a solo builder staring at a flat MRR graph and wondering how to diversify, I wish someone had pointed me to a specific, well-structured program instead of telling me to "build an audience first." So consider this me doing for you what I wish someone had done for me. Your portfolio doesn't need more complexity. It needs more income streams. Start with this one. Write the articles. Let the search engines do their thing. Watch the recurring revenue stack up month after month. That's the playbook. Now go run it.
