Family business × AI building AI
HARMONIC insight is a family-run LLC. My wife serves as Representative Director, leading finance, sales, and design; I (Erik) run operations and the design / development of every product, single-handedly. Implementation runs on Claude / Gemini / ChatGPT — every spec, build, and deploy is completed solo with AI. A company that sells industry-specific AI also runs entirely on AI internally — itself the strongest evidence of 10× productivity through AI.
Credentials
