William Imoh is the founder of Hackmamba, a developer marketing company, and the creator of Mural, a real-time voice app he built to learn Norwegian after moving from Dubai to Norway. He has a chemical engineering degree, taught himself to code, and spent four years as a product manager, but he had never written a line of Swift. In this episode, William shows how he used Codex and GPT-Live to build Mural natively for iOS and Android, then walks through the Lord of the Rings–themed Grok Bot “fellowship” that helps him run a team of about 25 as a solo founder.

What you’ll learn:

The design prompt that made Mural look nothing like any other language app
Why 1,000 days of Duolingo left him unable to hold a conversation in Norwegian
What GPT-Live-1 costs per session and the latency threshold that makes or breaks a voice tutor
How he assigned every solo founder role to a Lord of the Rings character in Grok
Why he gave his agents access to everything across 15 open tabs, except one thing
What he still has to do himself after the models improved
Why the fear that keeps him up isn’t replacement—it’s dependency
