How I got $100K off a single deck building Lunair (solo founder)

I became among the first solo-founders in my country to receive official funding from a VC.

How?

I've spent the last decade running Guyman Studio (animation/design - 5,000+ projects).

built a small tool to improve my writing, would love some feedback

I've always struggled with making my writing sound clear and natural, especially emails and professional messages.

So I started building RefineIQ, a small tool that helps refine text without changing what you're actually trying to say.

It's still early, and I'm trying to figure out what people find genuinely useful and what needs improvement.

If anyone wants to give it a try, I'd love to hear your honest feedback!

Blown Speaker Simulator – Turn your browser into a cheap car subwoofer

Have you ever wanted your high-end laptop to sound like a 1998 Honda Civic with a blown-out subwoofer? Probably not, but now you can!

Blown Speaker Simulator is a novelty Chrome extension built to test the absolute limits of Chrome's Manifest V3 and the Web Audio API. It captures your active tab's audio, isolates the low-end frequencies, and applies heavy digital distortion in real-time.

How it works under the hood: Since MV3 service workers don't support AudioContext natively, the extension uses chrome.tabCapture to send the media stream to a persistent Offscreen Document. Down in that layer, a BiquadFilter isolates and boosts the bass (+28dB), and a WaveShaperNode applies real-time clipping without perceptible latency.

I built this entirely with the help of AI, experimenting to see if I could create a complex audio graph without any prior audio engineering background.

I built sticky notes that hide in your screen edge (2 min demo)

Hey Solo dev here. My notes were always buried behind open windows, so I built HideNStick Notes for Windows.

Bump the screen edge twice and your notes slide out. Pin any note on top of any app, grab text from anywhere with Ctrl+Alt+C, then everything tucks away again. No account, works offline.
