FRACTIONAL CAIO
Dr. Hiroto Akatsuka
Fractional CAIO
Vendor-independent. I design the AI approach that fits your business — and make sure it lasts beyond the initial rollout.
Free 30-minute consultationWhen you might need me
- You want to adopt AI but aren't sure where to apply it, why, or how to measure the impact.
- Worried about data leaks, you can't bring AI into confidential work — or let staff use it safely.
- Your PoC never reached production — or it stalled when the people in charge changed.
- You can't judge in-house whether a vendor's proposal is technically sound.
What I do
AI adoption & process redesign, including generative AI
Where and why to apply it, how to measure impact, and where to keep human judgment.
Data governance for AI
Defining which data may go to which AI (cloud / on-prem / API), and within what limits; masking and access control included.
Privacy-preserving analytics & data release
Using differential privacy and related methods to build statistics and models, and share them externally, without exposing individuals.
Forecasting & optimization from mobility, traffic, and demand data
Turning large-scale data into prediction and optimization that works in production.
A technical advisor on your side
Joining vendor selection and negotiation to assess whether proposals are technically sound.
