領域を越えた事業開発経験 / Experience Across Markets & Businesses

正池有希子は、新しい事業や市場を、まだ答えが定まっていない段階から構造化し、実際に動く形へつなげる事業開発を20年以上にわたり手がけてきました。

キャリアの出発点は、財務・経営管理。その後、事業企画、マーケティング、組織改革、新規事業、海外市場開拓へと領域を広げ、テクノロジー、ヘルスケア、消費財、地域・文化など、異なる分野の事業に携わってきました。

日本だけでなく、英国を拠点とした欧州・中東での事業開発、米国市場での事業立ち上げ、中国を含むアジア市場の開拓など、複数の国・地域で新しい市場と事業機会をつくってきた経験を持ちます。

英国では、日本の大手テクノロジー企業によるAIを活用した新規事業において、欧州・中東および米国での事業開発に携わり、大企業との事業機会の創出、パートナー戦略、市場導入、製品・事業開発を推進しました。

それ以前にも、英国・欧州での新市場立ち上げ、中国・アジアでの販売・マーケティング戦略と市場開拓、事業再生や組織変革など、さまざまなフェーズの事業を経験しています。

領域や市場が変わっても、仕事の根底にある考え方は一貫しています。

一つの施策を単独で見るのではなく、目指す未来、戦略、商品、ブランド、営業、パートナーシップ、組織、実行、そして現場の細部までを一つの事業として捉えること。

表面に現れている問題だけで判断せず、小さな違和感からその背景にある構造まで遡り、本当に解くべき課題を見つけること。

そして、目指す状態をできる限り具体的に描き、そこから現在を逆算しながら、複雑でばらばらに存在する要素を、同じ方向に動く仕組みへ変えていくこと。

現在も、米国における新しいカテゴリーと市場の形成を含む、長期的な事業開発プロジェクトに深く携わっています。

正池の仕事に共通するのは、既存の正解や確立された進め方がない場所で、まだ形になっていない可能性を見つけ、事業として成立し、実際に市場で動く構造をつくることです。

Yukiko Masaike has spent more than two decades building new businesses and markets, often beginning at the stage where the answer—and sometimes even the path forward—has yet to be defined.

She began her career in financial planning and business management, before expanding into business strategy, marketing, organizational transformation, new business development, and international market development. Her experience spans technology, healthcare, consumer businesses, regional development, and culture.

Her work has taken her across multiple markets, including the United Kingdom, Europe, the Middle East, the United States, and Asia, including China, where she has developed new business opportunities and helped establish businesses in unfamiliar and evolving market environments.

While based in the UK, she worked on an AI-driven new business initiative for a major Japanese technology company, contributing to business development across Europe and the Middle East as well as the early stage of U.S. market development. Her work included developing opportunities with large enterprises, building partnership strategies, shaping market-entry approaches, and connecting emerging technology to real commercial opportunities.

Earlier in her career, she also led market development in the UK and Europe, built sales and marketing strategies across China and other Asian markets, and worked on business transformation and organizational change.

Across industries and geographies, the way she approaches business has remained remarkably consistent.

She does not look at an initiative in isolation. She looks at the future the business is trying to create, and at how strategy, product, brand, sales, partnerships, organization, execution, and the smallest details in the field connect to that future.

A small inconsistency can often point to a much larger structural issue. Her work involves tracing those signals back to their source, identifying the problem that actually needs to be solved, and reconnecting the different parts of the business so they can move in the same direction.

She begins by making the desired future as concrete as possible, then works backward to the present—turning complexity and ambiguity into a structure that can function in the real world.

Today, she remains deeply involved in a long-term business development initiative focused on building a new category and market in the United States.

The common thread throughout her career is working where established answers or playbooks do not yet exist—and turning emerging possibilities into businesses and markets that can actually work.
