Why this exists
A CTO's real job is knowing what goes wrong before it does.
A CTO's real job is not writing code. It is knowing, before anyone else, what is going to go wrong: which table is readable by the wrong people, which key is in the wrong place, which deploy has no way back, which feature should never have been built. Then making sure someone deals with it before a customer does.
Companies pay a great deal for that. Since 2018, Oshri has been that person for 30+ of them, directing up to twelve engineering teams at once across seven countries. A one-person product built with Claude Code gets none of it, at exactly the moment it needs it most: the first real users, the first payment, the first bad actor, the first customer who asks how it is built.
Red Corner is that job, done for the builders who cannot hire for it. You keep building with the tools you like. Oshri answers when it breaks, teaches the things that break, and sits down with you every month. That is the whole idea.
What Oshri does for you
Four things a CTO does that a prompt never will.
Reads what you built, not just what you asked
Before the first call ends, Oshri has looked at how your app is put together: where the data lives, who can read it, how you deploy, what happens when it fails. That is the part the AI never shows you.
Answers in chat when it breaks
You send a message Monday to Friday, 9am to 6pm Eastern, and all day Sunday. You get a CTO back, not a ticket queue. The answer comes with the why, so the next time you recognize it yourself.
Teaches the things that break, in groups
Group sessions on one subject at a time: secrets, auth, backups, migrations, payments. Recorded and added to the library, so the answer exists before you need it.
Sits down with you every month
A private 30-minute 1:1. Your roadmap, your risks, your next hire, your next launch. The conversation a founder with a CTO gets by default.
