Not as heavy as hiring a consultant. Not as lonely as figuring it out alone.
Brain Rental gives you access to an experienced professional's thinking —
exactly when you need it, for exactly as long as you need it.
Brain Rental (also known as Rental Brain) is on-demand access to an experienced professional's thinking. Not a retainer. Not a long-term contract. Just the brainpower you need, when you need it.
Instead of delivering thick reports, I help you think through your challenge and walk away with a clear next step. Think of it as a professional sparring partner — someone who listens, organizes, and helps you move forward.
Business, technology, strategy, creative — I work across domains. If I can't help, I'll tell you honestly.
No obligation to continue. Use it once, or make it a regular thing. Your call.
We talk. I listen, organize your thoughts, and help you identify concrete next actions.
Everything discussed stays between us. No exceptions.
Not just consulting. Not just AI. Six forces combined to tackle your challenge.
International business, management, CTO, government projects. Hard-won wisdom from the real world.
Cutting-edge AI for research, analysis, and creation. Human judgment multiplied by machine speed.
Business, technology, planning, storytelling, mathematics. A deep library across disciplines.
Trading company, government, private sector. An international network built across 6 countries.
Live information gathering and verification. Proposals grounded in the latest data.
Judgment that doesn't show up in data. Pattern recognition sharpened by decades in the field.
Tell me what you're working on, what's stuck, what you need.
I extract the core issues and structure them clearly.
I offer directions, options, and concrete suggestions.
You leave with a clear next action. The decision is always yours.
