# 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."
