Miguel Carranza built RevenueCat into critical infrastructure for thousands of mobile apps, and he'll tell you straight that he never wanted to be a manager.

He got his first computer at age eight and moved from Sevilla to Silicon Valley to build things. Somewhere along the way, he had to stop being the best engineer in the room and start hiring people better than him.

His worst hire is already on the team. That's not a red flag, it's the whole point of how he builds. The Office of the CTO, which he set up, exists precisely to keep that bar moving.

The engineering managers who never wanted the job are the ones who work out. The smallest pull requests have caused the biggest outages. And AI is making his teams smaller, not larger.

If you're a founder CTO trying to figure out when to delegate and when to dig in, this one will sit with you.
