Gwern reveals identity as Will DePue, retires from full-time writing to launch Guardian Angel venture

Longtime pseudonymous writer Gwern says he is retiring from full-time writing and ending pseudonymity, identifying himself as Will DePue. He says he will now focus on launching Guardian Angel, with the announcement shared via X and a longer post on his site.

The move highlights how influential independent researchers are turning audience trust and niche expertise into company formation. It also reflects a broader trend of pseudonymous tech voices moving into public-facing founder roles as their work becomes commercially relevant.
