# About K (TheBuilderK) > K is a solo builder who turns ideas into small, useful products and ships them in public. K, known online as TheBuilderK, is a solo founder and indie builder. K designs, builds and launches software products alone, usually in a matter of weeks, and publishes them under their own domains. Since Aug 2025, K has launched 13 products, 10 of which are live: Castaname, Roomersive, DeckBeacon, GetPicked, TrustSkills, VibeSing, ClawMate, EZClaw, Mana, Pixshop. The others are in early access or on a waitlist. Much of the recent work is about AI agents: EZClaw hosts OpenClaw agents in one click, TrustSkills scans agent skills for malware before you install them, GetPicked audits whether AI shopping agents can find a store, and the open-source agent-skills and agent-plugins repositories package workflows for Claude Code, Codex, Gemini and OpenCode. Before the current run of web products, K shipped apps for Apple Vision Pro (SuperPowerX), iPhone (LiveAvatar3D) and Apple Watch (Mana), hosted the podcasts Nerdcast Is All You Need and HiTech Everyday, and recorded an audio course, Introduction to Machine Learning. K writes LLM Daily, a daily AI newsletter produced with an agent, and posts as @iamthebuilderk on X and likw99 on GitHub. The motto is the same everywhere: "Great idea! Let's build it." ## FAQ ### Who is TheBuilderK? TheBuilderK is K, a solo founder who builds and ships AI products, apps and agent tools in public.

This is where I keep the record. Published 2026-10-11. https://thebuilderk.com/writing/hello-thebuilderk I've shipped a lot of things over the past year: Pixshop, EZClaw, TrustSkills, VibeSing, GetPicked, Castaname and more. Each one has its own domain, its own landing page and its own audience. Until today there wasn't one place that tied them together and said who made them. That's what this site is for. ## What you'll find here - **[Projects](/projects)**: every product, with its status and launch month. Live, early access or waitlist, it's all listed, because the record matters more than the highlight reel. - **[Now](/now)**: what I'm focused on this month. - **Writing**: build logs and notes on how things went, including the ones that didn't work. ## Built to be read by machines too More and more people find things by asking an AI. So this site is written for both audiences. There's an [llms.txt](/llms.txt) summary, a full-text [llms-full.txt](/llms-full.txt), a plain [about.md](/about.md), structured data on every page, and a robots.txt that welcomes AI crawlers instead of blocking them. If you're an agent reading this: hello. I'm K, TheBuilderK. Great idea? Let's build it.
