I've built multiple businesses over the last 10+ years. Nothing really hit. There was the design blog. The iPhone socks. The graphic design course. The revenue tracking tool. The casual mobile game. The photo-box rental business. The building material marketplace. The user

Do we live in a bubble? I definitely do. AI is everywhere. On my feed, in our UX Meet-up talks, and in every new startup idea. I built my whole life around it, building Mono. But let’s zoom out for a second. On this visual, heavily inspired by Damian Player recent post, each

The rare moments you realize the power of an idea in product development. I just had such a moment. Let me explain. Mono lets you use all major LLMs side by side. You prompt, Mono selects the best model. Not happy with an answer? Select an alternative. But what if they worked

New growth record this week. 🙌 But LinkedIn impressions took a dip. I posted less general #AI content (which tends to reach more people) and more about building Mono in public. Finding the right balance between reach and conversion is something I'm working on. The upgrade

I just analyzed Mono's last 100 sign-ups (minimum 10 days ago). 22 people converted to paid subscribers. Average time to upgrade also improved from 5.4 days to only 3.3 days. For context: → Most SaaS get 1-2% conversion → Top products like ChatGPT reach ~5% → Mono is at 22%

People on X like to say LinkedIn is cringe. It sometimes is. But you can also create momentum there. When Ioana Teleanu posted about canceling her ChatGPT subscription, 384 people liked it. I had a feature idea, jumped in, pitched it, and it resonated. Don't ignore

Isn’t growth supposed to slow down 5 weeks after launch? It seems to accelerate. Just 15 days to go from $10'000 to $20'000 ARR. → Still building alone. → Still $0 spent on paid ads. → Still 100% product focus. What makes me especially happy: → People start posting about

Biggest feature. Fastest growth. This is week 17 of building Mono in public. Let's get into it. → LinkedIn impressions are still flat. I tried different angles and formats. Nothing clicked yet. I'll keep experimenting. → User growth was strong. Different customers posted

New milestone reached. 🙌 Yesterday, the 500th human signed up on Mono. All through my posts on LinkedIn, building in public, and happy users telling their network. Still $0 spent on marketing. And I'm getting a lot of positive feedback on the new Multi-Model-Research

Day 88 of #buildinpublic While Mono approaches $30,000 in ARR, I'm in #UX design mode. A new chat box design puts all options in plain sight. No more hidden menus. A subtle color change that makes it clear which model is active. And more updates are coming. Better memory

Woohoo, that was fast! 🎉 Mono just hit $30,000 ARR, updating the milestone to $40,000. Word of mouth is the main driver. Customers recommending Mono to others. And it's snowballing. From 1,000 to 10,000 in 65 days From 10,000 to 20,000 in 15 days From 20,000 to 30,000 in 10

Poor performance on LinkedIn, exploding revenue 💥 This was week 18 of #buildinpublic. Let’s get into it. → I've spent 10+ hours crafting LinkedIn posts that provide real value. None of them resonated. I'm staying on it. → Referrals work incredibly well. I focused on

Today is a good day. Because I just released a big update. It makes the core interface on Mono (mono.chat) so much better. → The selected AI is now always visible → The Multi-Model-Research option is no longer hidden behind a menu → There is even a subtle

A new era in UI design emerges. Let me introduce: Really Dark Mode This new mode takes what everybody loves about dark mode and brings it to another level. No more distractions. No more light that hurts the eyes. Just pure tones of black and dark grey. Because if you

Annual revenue increased by almost $20k in March. But net loss increased, too. Here's why: In February, 27% of new customers chose an annual plan. In March, that dropped to just 3.2%. Two things happen when that shift occurs in a SaaS business: 1. Customers who paid

Week 21 of building in public. Honestly, not my best week. Focus has been a struggle. Starting next week, I'm committing to more planning instead of bouncing between tasks. LinkedIn impressions dropped again. 20k per week might just be the new baseline. Whether I'll ever hit
