Lynen

I built the process to monetize. I'm missing the brands to fill it.

The idea on how to monetize was simple: AI recommends an outfit, surfaces real products from real brands, user buys something, I earn a commission. Clean and aligned with what the user is already doing in the app.

So I built it.

Then I tried to join the affiliate programs of known brands.

90% rejected me.

Not enough traffic. Not enough users. Not an interesting partner yet.

So here's the loop I'm stuck in: I need users to get brands. I need brands to monetize. I need to monetize to keep growing. The snake eating its own tail.

Beyond the partnerships, the product itself is harder than it looks:

1. AI recommends an outfit

2. AI maps it to product categories

3. Query searches the catalog.

In theory, clean. In practice, the products that surface are sometimes nothing like what was recommended. Matching intent to inventory is its own unsolved problem.

I also tried letting users scan a real outfit to detect garments and find similar products. The AI detects the pieces fine. Then it fails to match them to anything relevant in the catalog.

And even when a user does want to buy something, each product redirects to a different vendor page. There's no unified cart. No "buy this look" flow. Just five tabs opening in a browser. Not exactly a frictionless purchase experience.

If you've navigated affiliate programs as an early-stage app:

• How did you get your first real brand partnerships?

• How do you improve garment matching?

• And if you've solved the "multiple tabs" friction problem, I'd love to know how you did it.

Shakespeare had no idea he was writing about paid acquisition.

But here we are, 400 years later, and the question still stands. To be present. Or not to be. Obviously the answer is yes, but the real question is where, how much, and how do you know if it's actually working?

I'm Eduardo. Solo founder of Lynen, an AI styling app for men. So far I've been growing organically. But now I'm facing the decision I've been avoiding: where do I actually put money?

Every channel seems to be the most important one. The one that's going to make the difference.

• Instagram. TikTok. Google UAC. Apple Search Ads. Reddit. ASO. Influencers.

You can't be everywhere. But you also can't afford to bet wrong and find out three months later.

And it's not only money, it's also time. Paid ads need budget. Content needs time. Communities need consistency. As a solo founder working a 9-to-5, I only have so much of each. Every channel I add isn't just a line item. It's a decision about what I won't be doing instead.

So the question nobody seems to answer clearly: what's the actual ROI? Not the success story. Not the "I spent €50 and got 500 users" tweet. The real number. The channel that actually works first. How to reach new users without needing a content agency, a paid ads specialist, and three more things I can't afford yet.

I genuinely don't know. That's why I'm asking.

If you've run paid acquisition for a consumer mobile app — what moved the needle? What burned your budget with nothing to show for it?

I work a 9-to-5. I'm building Lynen on the side — an AI styling app for men who want to dress better but don’t know where to start.

During the week, progress is fragmented.
30 minutes before work. A quick session at lunch. An hour at night when I’m already tired.

You fix small things. You lose context. You move slowly.

The weekend is different.

Saturday morning. Friends are making plans. The group chat is active.

I put my phone down and open my laptop.

Not because I have to but because it’s the only time I get real depth.

That’s what’s actually hard about building on the side.

It’s not the work. It’s wanting to do both, go out and keep building, at the same time.

Some weekends I fix bugs. Some I analyze why users drop off. Some I tweak prompts until the output actually feels like a real stylist.

By Sunday night, something exists that didn’t exist on Friday.

If you’re building in 30-minute blocks, you’re shipping fragments.

Weekends are where you build something real.

I've been building Lynen, an AI personal styling app for men, for months. The product works. It's live on the App Store and Play Store. I'm proud of it.

But when it came time to actually show it to the world through social media, I froze.

I'm a solo founder. I built the whole thing myself. I can debug a Supabase Edge Function at 1am without breaking a sweat. But standing in front of a camera? Posting something that people would actually see me in? That felt different. That felt exposed.

Recording took way longer than I want to admit. I did it too many times. I hated how I looked, how I sounded, how unnatural the whole thing felt. I almost didn't post it.

Then I uploaded it. And I sat there staring at my phone waiting for... I don't know. Silence? Mockery?

What I got was support. Real, genuine support from people who know me (and even a few who don't).

It wasn't perfect. But it was out there, and that matters more than I expected.

The lesson I keep coming back to: the thing you're avoiding is never as bad as the version of it living rent-free in your head. The gap between "what I imagined would happen" and "what actually happened" was enormous, and entirely in my favor.

If you're a founder sitting on content you haven't posted because it doesn't feel ready, or you're scared of how it'll land: just post it. The people who care about you will show up. And the ones who don't? They weren't your audience anyway.

Now I just have to do it again next week. 🙃

Yes, you read correctly, I'm tired of asking my mom if my outfit is good enough for a date I might be having, or to hang out with friends, etc.

Until now, I always played it safe with boring basics, looking the same every single day. Every fashion app I tried was built for women. Men who want to dress better but don't know how are completely ignored.

And that's why I built Lynen, so I can become a functioning adult that knows how to dress properly for every occasion (without asking his mom as much). The app tells you if your outfit works and it can also give you inspiration when you're stuck. Built specifically for men.

Where I am today:

• Live on the App Store (Play Store coming soon)

• 50-200 early users, all organic, zero paid acquisition

• Hired a friend to help with social media (hardest part until now is creating content with my face in it - and I'm still not there)

What I'm figuring out now:

• How to grow without a budget

• Whether to focus on content, ASO, or communities first

Happy to share what's working and what isn't as I go. And if you've got any tips for a solo founder with zero experience building apps (and how to grow them) I'd love to hear it.
