6 weeks ago I launched a side project. Today it has 10,000 active users, 250+ products listed, 50+ independent creators, revenue coming in, and I quit my business development job to go full-time on it.
The project is Agensi a marketplace for AI agent skills. If you use AI coding agents like Claude Code, Cursor, or GitHub Copilot, you can install SKILL.md files that make your agent better at specific tasks. Code review, testing, documentation, DevOps, git automation. Think of it like an app store but for AI agent capabilities.
I'm not a developer. I built the entire thing with Lovable and Claude. Here's what happened.
Week 1: The idea that almost didn't happen
I was using Claude Code daily for work and kept searching GitHub for SKILL.md files to make it better at code reviews. The experience was terrible. Random repos, broken YAML, no way to know if a skill was safe to install. I found one that looked like it had prompt injection buried in the instructions.
I mentioned this to a friend and he said "sounds like there should be an app store for that." I spent the weekend building a v1 with Lovable. It was ugly but it worked. Listed 15 skills I built myself. Showed it to a few people in Discord. Three of them uploaded their own skills within 24 hours.
Week 2-3: The SEO play that changed everything
I had a working marketplace but zero traffic. I almost spent money on ads. Instead, I decided to try something different: I treated every product page as a landing page and started writing articles targeting specific search queries.
Not generic "what is AI" content. Specific questions like "where are Claude skills stored" and "how to install skills in Codex CLI." I found these queries by checking Google Search Console for what terms were already showing impressions.
I wrote 30 articles in two weeks. Claude did the keyword research by analyzing my GSC data, finding gaps, and identifying queries where I had high impressions but no dedicated content. Every article followed a structure: Quick Answer block at the top (40-60 words), H2 headings phrased as questions, FAQ schema, internal links to related articles.
By the end of week 3, I had 50+ page-1 Google rankings. Traffic started compounding.
Week 4: The AEO moment
Something unexpected happened. I checked Google Analytics and saw traffic from chatgpt.com, gemini.google.com, and perplexity.ai. AI engines were citing my site when developers asked where to find SKILL.md skills.
I didn't optimize for this intentionally at first. But the article structure I was using (Quick Answer blocks, question-format H2s, FAQ schema) was exactly what AI engines prefer to extract and cite. So I doubled down. Added Organization + Person schema for entity anchoring. Created an llms.txt file. Made sure robots.txt allowed all AI crawlers.
Today: 350+ AI-referred sessions per month from 9 different AI engines including ChatGPT, Gemini, Perplexity, Claude, and even Doubao (ByteDance's AI). This channel is growing faster than organic search.
Week 5: First revenue and the "oh shit" moment
A creator uploaded a premium skill with reference files, scripts, and an OWASP checklist. Priced it at $10. Someone bought it within 48 hours. Then two more sales. Then an MCP subscription ($9/month for live agent-native access to the full catalog).
The numbers were small but the model worked. Creators upload skills, set their own price, keep 80% of every sale through Stripe Connect. The marketplace takes 20%. Every skill goes through an 8-point automated security scan before it goes live.
I did the math. If I could get to 1,000 skills and maintain the current growth trajectory, the marketplace commission alone would cover my salary. The MCP subscription added predictable MRR on top.
Handed in my notice on Monday, had my last day on Friday.
Week 6: The current numbers
10,000+ monthly active users
250+ skills from 50+ creators
150 articles across 12 topic clusters
350K Google impressions/month
1,000+ organic clicks/week
850+ page-1 rankings
350+ AI-referred sessions/month from 9 AI engines
39 paid transactions, 4 MCP subscribers
$0 spent on ads. Ever.
Where this is going
The marketplace is step one. The bigger vision is becoming the trust and distribution layer for AI agent capabilities, not just skills, but any capability an agent needs to do its job better.
Right now SKILL.md is the standard. Tomorrow it might be tool configs, MCP integrations, workflow templates, or something that doesn't exist yet. The format will evolve. What won't change is that agents need capabilities, those capabilities need to be trusted, and creators need a way to distribute them.
We already have the MCP server live, your agent connects to Agensi and searches, evaluates, and loads skills on demand without downloading anything. That's the first version of what an agent-native marketplace looks like. By 2027, both sides of the marketplace run through MCP. Creators publish through their agent. Buyers discover and install through theirs. The web UI becomes optional.
The endgame: when any AI agent anywhere needs a new capability, Agensi is where it looks first. Curated, scanned, accountable. The trust layer the ecosystem doesn't have yet.
What I'd tell you if you're building a side project
Don't build for 6 months in stealth. I launched an ugly v1 in a weekend and got real users within days. Their feedback shaped everything that came after. The product I have now looks nothing like that first weekend build.
SEO is the most underrated growth channel for side projects. Everyone chases Product Hunt launches and Twitter threads. Those give you a spike that dies in 48 hours. Every article I wrote 6 weeks ago still drives traffic today. Content compounds. Ads don't.
Use your side project's data, not your intuition, to decide what to build next. I don't guess which articles to write or which features to build. I look at GSC data, GA4 data, and skill request submissions. The users tell you what they want if you set up the right feedback loops.
The "should I quit my job" question answers itself. I didn't quit because I felt confident. I quit because the growth curve made it irrational not to. When your side project is growing 50% week-over-week with zero paid acquisition, the opportunity cost of staying employed is higher than the risk of going full-time.
AEO is the cheat code nobody is talking about. If your side project's content is structured for AI engines (Quick Answer blocks, FAQ schema, entity anchoring), you get a distribution channel that literally didn't exist 18 months ago. 350 sessions/month from AI citations and I've barely started optimizing for it.
The site is agensi.io. Happy to answer questions about the build, the growth strategy, the tech stack (Lovable + Claude + Supabase + Netlify + Stripe), or the decision to go full-time. Also open to feedback on the product itself, that's why I'm posting here.
If you're a developer who builds SKILL.md skills or .cursorrules files, you can publish them on Agensi and start getting users (and revenue) from day one. And if you need a skill that doesn't exist yet, drop it on the skill request board creators get notified and build to real demand.
