About
We design strategy, turn it into systems, and stay until it works.
Consilegy builds the revenue architecture, CRM structure, and GTM operations that make Japan execution visible to you and to your HQ. We also build our own product, Revenue CRM, officially launched on September 28, 2026.
Contact UsOur Mission
Give society more choices.
- Choices change the future.
- Move what you want to do forward.
Companies that can't move forward on what they want to do aren't short on ambition. They just can't see which paths are open. Once the structure is visible, choices appear. And when a company chooses and moves forward, new choices open up for its people and its partners too.
What usually stops a choice is a lack of time and hands. So Consilegy doesn't advise from the outside. We join as part of your team. Your 24 hours, plus ours. A 48-hour day. We work alongside you from strategy through implementation and adoption, and we turn what we learn into Revenue CRM, a tool we share with more companies.
Founder
Seiko Yamaguchi
Founder, Consilegy LLC
Seiko began her career in IT consulting, then built an independent practice in 2015 advising companies across Tokyo on marketing strategy, CRM implementation, and project management. Her client work spanned SaaS, consulting, healthcare, retail, and entertainment, with a consistent focus on Japan-facing and cross-border B2B contexts. She founded Consilegy LLC in 2025 to bring that work together under a dedicated firm for Japan-facing revenue architecture.
Her work sits between strategy and execution: the GTM structure, revenue architecture, and operating systems that let global teams move effectively in Japan. She holds a PMBOK-based project management background and brings hands-on delivery experience across both market-facing design and CRM/RevOps implementation.
Bilingual in Japanese and English, she works directly with both sides of global-Japan teams, reducing the friction that typically accumulates when strategy is designed in one language and executed in another.

Where Revenue CRM came from
The product took shape at Hualien Cloud Hub (花蓮雲基地), run by Hualien County. Seiko stayed there with the first cohort, and the shape of this product, CRM and AI together, came out of working alongside founders and remote workers from several countries.
See News (花蓮視新聞) covered the stay and the build in its 25 June 2026 edition. Read the article
Why Consilegy
What sets our work apart
- Bilingual without interpretation loss
We work with you in English and with your Japan team in Japanese, so nothing is diluted between the two sides. For English-speaking leaders managing Japan operations, this is the gap most consultants can't close.
- Japan operations depth
We understand the structural gap between how global revenue systems are designed and how business actually moves in Japan, from trust-building cycles to stakeholder dynamics to CRM adoption patterns.
- Strategy through implementation
We do not stop at recommendations. We connect planning to CRM configuration, workflow design, and launch, and stay until the system works in practice.
- Disciplined delivery
We manage scope, dependencies, and cross-functional execution with PMBOK-grounded discipline, not advisory alone.
- HubSpot and RevOps experience
We support CRM implementation, workflow design, reporting, and adoption with hands-on delivery across Japan-facing engagements.

What We Believe
How we make decisions
Measurable assumptions over vague opinions. We build the infrastructure that makes data usable for decisions.
Delivery that doesn't connect to business results isn't finished. We define what success looks like before we start.
Progress through validation is more reliable than overbuilt planning. We prefer reversible steps and clear signals.
We care about whether the thing actually works, not just whether the work was done. That distinction shapes how we engage.
