Don't just talk strategy.
Build the operations that make it move on the ground.
Financial analysis surfaces fair value;
non-financial analysis surfaces premium / discount factors.
Grounded in three domains of experience — investor, consultant, in-house — and AI implementation that loosens the bottlenecks where work actually happens.
Translate boardroom strategy into operations that actually move.
An independent strategist with three domains of experience — investor, consultant, in-house —
combines three layers (financial analysis, non-financial analysis, AI operations platform)
to deliver cross-cutting strategy and operational improvement across the corporate function and business units of listed companies.
Financial analysis surfaces fair value;
non-financial analysis surfaces premium / discount factors.
We back both with hands-on support through PM support and coaching during the improvement-implementation phase.
And we implement an AI operations platform to make day-to-day work more efficient.
Combine the services freely as the situation demands
to address the specific challenges of your organization.
Sum-of-the-Parts Analysis
Decompose conglomerate value by segment, re-aggregate at industry multiples, and surface the share-price discount factors.
Bottleneck & Solution Design
Structure the bottlenecks behind the discount factors and design concrete improvement plans aligned with management decisions.
Available during the improvement-implementation phase of either Financial or Non-Financial Analysis. Choose PM Support (participating role inside the project) or Coaching from outside the project.
Implementation PM Support
Design and teach a QCD management framework, then walk alongside your PMO. When the team faces overload, we propose five concrete optimization levers.
Implementation Coaching
From an external position, walk alongside in three modes: strategic dialogue, frontline diagnosis, and causal-path redesign.
Materiality & KPI Review
Provide an objective review and improvement points for materiality and KPIs that were built primarily to satisfy external requests.
Materiality & KPI Revision
Revise materiality and KPIs into something that matches reality, and drive implementation through to live operations.

Process Redesign for AI
Surface person-dependent work and tacit knowledge, then rebuild operations into reproducible processes that AI can plug into. Hands-on.
AI Operations Platform
Bridge the data disconnect between DWH and front-end apps; implement cross-cutting architectures that effectively connect existing SaaS tools.
Data Cleansing & Context Coaching
Coach the practice of converting scattered data into operational context, designed for sustainable in-house operation.
AI Environment & Dialogue Design
Pair an environment design that holds AI tendencies in check with a dialogue protocol that refuses to leave AI unsupervised.
Python Automation Coaching
Coach your team to design AI-assisted Python automations themselves.
Python Automation Implementation
ethosola designs and builds your business-process Python automations, leveraging AI throughout.
From single engagements to fully customized combinations across multiple services to fit your specific challenges.
Service-level details are walked through during the initial conversation.
An independent strategist implementing financial × non-financial × AI
A practitioner who turns ideals into actual returns.
Earn first, talk ideals later.
That is the first step toward sustainability.
More than seven years on the front line of investor relations, then a Big-Four ESG-related business consulting practice, then a sustainability function at a major listed corporate — three field experiences form the spine of ethosola. Being able to translate the investor view, the consultant view, and the in-house view from the inside is the precondition for support that actually lands on management decisions at listed companies.
Today active as an independent strategist who builds with Python and AI directly. In one recent engagement, the core of an AI operations platform was built hands-on using a lightweight architecture that effectively connected existing SaaS tools. The style — "don't just talk strategy; write the code yourself and ship it" — accelerates operational improvement in IR and Sustainability functions.
Front line of investor relations, Big-Four ESG-leaning business consulting, and the sustainability function at a major listed company. The ability to move between the investor, consultant, and in-house perspectives — from the inside — connects directly to designing improvement plans that actually run on the ground.
Having owned the implementation phase from the in-house side, we can design improvement plans on the assumption they will actually run. Anticipating where implementation gets stuck — that is where this differs from purely desktop consulting work.
Built core AI operations platform functionality in a short timeframe using a lightweight architecture that effectively connected existing SaaS tools (PoC). We can deliver designs that maximize existing SaaS investments while keeping additional cost in check.
— Classical synthesis, in pursuit of the essential —
"ethosola" is a coined word combining the Greek "ethos" with the Latin "sola."
In medieval Scholastic philosophy, Thomas Aquinas integrated sophisticated Greek philosophical concepts into the rigorous Latin tradition, then connected those concepts to one another to approach truth.
— This is, in the history of knowledge, a universal and orthodox approach.
Why would a modern Japanese person take a name from such Western classical languages?
Because the medievals — though predating our supposedly "more advanced" modern Japanese society — faced essence more honestly than we do.
We believe their stance is something worth learning from.
Spiritual essence; character; the foundation of trust
Sole, singular; that which stands on its own
To fuse financial × non-financial × AI and produce essential value (ethos) — not as a slogan, but as actual returns. To stand independently (sola), free from the conformity pressures and hollowed-out processes that linger in Japanese society.
Holding these two ideals,
we operate as a true professional, unburdened by attachments.
Automated business analysis that could not use external services due to security requirements, in a fully in-house secure environment. Built end-to-end from aggregation to report generation, on a lightweight architecture that taught the AI the operational context it needed.
Cross-search across the proliferating set of standards — SSBJ, IFRS S2, GRI, CDP, and more — to respond instantly to investor inquiries. A response platform that can read image-based materials too, built around the approach of converting data into operational context.
