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.

When you might need me

You want to adopt AI but aren't sure where to apply it, why, or how to measure the impact.
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.
Confidential data is keeping your AI plans stuck.

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.
