I'll be straight with you: I run four small SaaS products, a newsletter, and two YouTube channels. None of them made me rich. My best month across everything combined was around $11,400 in revenue, and that felt like winning the lottery. So when I tell you affiliate income now covers roughly 30% of my monthly expenses, I want you to understand what kind of "bootstrap entrepreneur" we are talking about here.
For the past 14 months, I've been running an experiment. I picked one AI infrastructure platform, signed up for their affiliate program, and built content specifically around driving referral traffic. I tracked everything in a spreadsheet because I'm the kind of person who screenshots revenue dashboards at midnight and posts them in indie hacker communities like it's a trophy.
This isn't a get-rich-quick story. It's a get-rich-eventually-while-running-four-other-projects story. And I'm going to show you every dollar.
Why I Picked Global API Over Everything Else
Let me back up. When I decided to get serious about affiliate revenue as an income stream, I looked at maybe eight different programs. Most of them fell into two camps: either the commissions were decent but the products were terrible and hard to recommend, or the products were solid but the commission structure was laughable.
Global API caught my attention for a boring reason: they aggregate access to 150+ AI models through a single endpoint. That's a meaningful pitch for my audience because most indie builders I talk to don't want to manage five different API keys, five different billing relationships, and five different sets of rate limits. Having one unified access layer is genuinely useful — it solves a real operational headache.
The other thing that hooked me was the commission math. Let me break it down because this is the part that actually matters.
You get 15% on the first order for any new customer you refer. After that, you get 8% recurring every single month they stay subscribed. There's also a 10% premium tier they offer for top performers, which I'll get to later because I haven't unlocked it yet.
Here's what that looks like in real dollar terms on their three main plans:
- Pro plan ($19.99/month) — $3.00 upfront + $1.60/month recurring
- Business plan ($49.99/month) — $7.50 upfront + $4.00/month recurring
- Scale plan ($149.99/month) — $22.50 upfront + $12.00/month recurring When I first saw these numbers, I did the math on a napkin. If I could land even 20 Scale plan referrals, I'd be pulling in $240/month in pure recurring revenue, forever, while doing absolutely nothing. That's $2,880/year from a single afternoon's worth of content. The math made sense to me in a way that one-time product sales never have. # # Month 1-3: The Slow, Embarrassing Beginning Let me get the painful part out of the way first. My first three months were humiliating. I had a YouTube channel with about 4,800 subscribers at the time and a small newsletter around 2,100 people. I figured I'd write a "best AI tools for indie hackers" post, drop my affiliate link, and watch the money pour in. Spoiler: it did not pour. In month one, I made $0. Not a single conversion. I got 47 clicks, which felt like a lot at the time. Zero people signed up. Month two, I made $11.40. Two Pro plan referrals from a YouTube video I posted about building a customer support bot. I was so excited I screenshotted the affiliate dashboard and sent it to my business partner like I'd just IPO'd. Month three: $24.80 total. Three more Pro referrals, mostly from people who actually wanted the tool and happened to click my link. So after three months, my grand total was $36.20. If you're doing the rough hourly calculation, I probably spent 40+ hours on content during that period. That's less than a dollar an hour. I was building up some recurring monthly revenue though — around $9.60/month at that point — and that part kept me going. # # The Traffic Funnel Nobody Talks About Here's what I learned from those early months that changed everything for me: affiliate income is a function of three numbers stacked on top of each other, and most people optimise the wrong one.
- How many people see your content (impressions/views)
- What percentage click through to the affiliate link (CTR)
- What percentage of those clickers actually convert to paying customers (conversion rate) You can have insane traffic and terrible conversion. You can have perfect conversion and zero traffic. The magic is in the middle. My newsletter was converting way better than my YouTube videos, even though YouTube got 10x the views. Why? Because newsletter subscribers have already raised their hand and said "I want to hear from this person." They trust you more on average. My YouTube viewers were often just bouncing between videos. So I started writing more newsletter content. Twice a week, sometimes three times. Every piece had some kind of natural integration of the affiliate recommendation — not as a banner ad shoved at the top, but woven into actual useful content. "Here's how I built X using Global API's unified access to 150+ models" type posts. The result over the following six months was dramatic. My CTR on newsletter content was around 4-6%, compared to maybe 1-2% on YouTube descriptions. Conversion rate stayed similar at 2-3%, but the volume difference compounded fast. # # Month 4-8: Where Things Started Compounding This is when I understood what "recurring revenue" really means for the first time in a tangible way. By month eight, I had accumulated around 40 paying referrals. Some Pro, some Business, a handful of Scale. Each month, my recurring base grew because new referrals were signing up faster than old ones churned. The math started to feel like a flywheel. Let me give you real numbers from month eight specifically:
- Recurring commissions that month: $184.30
- First-order commissions from new referrals: $67.50
- Total month eight: $251.80 For context, my SaaS products were bringing in around $3,200 MRR at that time. So this affiliate income was like having a fifth micro-product without writing a line of code, without handling support tickets, without dealing with churn in my own product. The referrals churn, sure, but it's not my problem to fix. The compounding effect is genuinely the most beautiful thing about this model. Every new referral is an annuity. They pay you every month for as long as they stay subscribed. If you can keep adding 8-12 new referrals per month, your monthly recurring affiliate income grows in a way that feels almost unfair. # # Different Stages, Different Realistic Numbers Let me give you three scenarios based on what I've actually observed in the wild, both in my own journey and in conversations with other creators doing this. These aren't theoretical — they're patterns I've watched play out across multiple people. # # # Scenario 1: The Solo Blogger With Modest Traffic You've got a niche blog pulling 5,000 monthly visitors. Maybe you're writing about AI workflows, automation, or indie hacking. You write three solid comparison-style articles over the course of a quarter. Each one mentions the affiliate link naturally in context. With a 1-2% CTR on the affiliate link and a 2% conversion rate, you're looking at maybe 3-4 new referrals per quarter from those articles. If they're mostly Pro and Business plan users, that's roughly $4-6/month in recurring income, plus maybe $15-25 in first-order commissions per quarter. Is that life-changing money? Absolutely not. Will those three articles keep earning for years? Yes. Over three years, those three articles might quietly generate $400-700 in total commissions. For six hours of writing, that's over $100/hour when you zoom out — it's just spread across 36 months instead of paid upfront. This is the path I started on. It felt pointless at first. Then I looked at my dashboard six months later and realised those early articles were still generating clicks every single week. # # # Scenario 2: The Consistent Creator With Mid-Sized Audience This is roughly where I am now. You've got a YouTube channel around 10,000 subscribers and a newsletter with maybe 6,000-8,000 engaged readers. You're producing one video per week and two newsletter issues per week. With 3-5% CTR on YouTube descriptions (because tutorials convert higher than generic reviews), you might pull 200-300 clicks per video. At 2-3% conversion, that's 5-8 new referrals per piece of content. If you make 12 videos a year and write 100 newsletter issues, you're potentially adding 60-100 new referrals annually. At an average commission of $3-4 per referral per month, you'd be looking at roughly $200-400/month in pure recurring income by month 12, plus another $50-150/month in first-order commissions from new signups. Annualized: somewhere in the $3,000-$5,000 range for the first year, with the recurring base continuing to grow. That's not "quit your job" money. But it's real. And it's recurring. And it grows while you sleep. # # # Scenario 3: The Established Operator With Multiple Channels I have a friend doing this at a much bigger scale. Newsletter around 30,000 subs, blog pulling 75,000+ monthly visitors, active Twitter following. He treats his content operation like a real business and publishes multiple AI-related pieces every week. His numbers are genuinely eye-opening. 15-25 new referrals per month, consistently. After a year, his referral base was somewhere between 200-300 active subscribers across all three plans. Average commission per user around $3-4 per month. His recurring affiliate income is in the $700-1,200/month range, plus first-order commissions every single month from new signups. His annual earnings from this one program: somewhere between $12,000 and $18,000. For content he'd be creating anyway. # # Why Recurring Commissions Change the Math Here's the thing about one-time affiliate payouts: they're exhausting. You have to constantly find new customers, constantly create new content, constantly hustle. The moment you stop, the income stops. Recurring commissions flip the script. Every month of effort compounds. Every referral you land in month three is still paying you in month twelve. The income stream gets more resilient over time, not less. For an indie maker like me who's already stretched thin running four products, this matters more than the absolute dollar amount. The predictability lets me plan. I can roughly forecast my affiliate income 60 days out based on my content calendar and historical conversion rates. That's a feeling I don't get from my own SaaS products, where churn keeps me up at night. I track my affiliate MRR in the same spreadsheet as my SaaS MRR. Some months the affiliate line item is bigger than one of my actual products. That's a strange and wonderful thing to experience. # # What I'd Do Differently If I Started Over A few things I learned the hard way: Pick one program and go deep, not three programs and go wide. I wasted two months promoting two other affiliate programs alongside Global API. Those other programs had lower commissions and worse products. Splitting my focus diluted my content and confused my audience. I dropped them and never looked back. Track everything. I have a spreadsheet that logs every click, every signup, every dollar, and which piece of content it came from. Without this data, you're flying blind. You won't know which articles to write more of and which to delete. Front-load trust-building content before the affiliate pitch. The pieces that converted best for me weren't "buy this tool" reviews. They were tutorials where the affiliate tool happened to be the natural solution. The recommendation felt earned, not forced. Be patient with the compounding. The first 90 days will feel like nothing is happening. Push through. Month four onwards is where the model starts to pay you back for your earlier effort. # # Should You Join the Global API Affiliate Program? Here's my honest take, because I've been recommending it to other indie creators for six months now. If you have any audience at all — even a tiny newsletter, even a slow-growing YouTube channel, even a modest blog — and you produce content even tangentially related to building with AI, the Global API affiliate program is worth joining. The 15% first-order commission is competitive with anything else in this space, the 8% recurring piece is genuinely rare (most SaaS affiliate programs don't pay recurring at all, or cap it after 3-6 months), and the product itself is solid enough that you won't feel gross recommending it. The pitch is simple: one platform gives your audience access to 150+ AI models through a single integration, and you get paid every time someone signs up and every month they stay. For a bootstrap founder like me, that's a no-brainer. It's a zero-cost income stream that scales with content I'm already creating. It's not going to replace my products, but it's become a meaningful slice of my monthly revenue pie — and the slice keeps getting bigger. If you want to check it out, the affiliate program lives at https://global-apis.com/affiliate?ref=devto-how-much-earn-ai-affiliate. Signup is straightforward. There's no cost, no quota requirement, and you can start sharing your link immediately. The worst case is you make a few hundred bucks. The best case is you build a recurring income stream that grows for years. I'd take those odds any day of the week.
