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 at the intersection of strategy and execution: designing the GTM structure, revenue architecture, and operating systems that allow global teams to 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.

Why Consilegy
- Bilingual without interpretation loss
We work directly with you in English and with your Japan team in Japanese, so nothing gets 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 don't stop at recommendations. We connect planning to CRM configuration, workflow design, and operational launch, and stay until the system works in practice.
- Disciplined delivery
We manage scope, dependencies, and cross-functional execution with PMBOK-grounded project discipline, not just consulting-style advisory.
- HubSpot and RevOps experience
We support CRM implementation, workflow design, reporting, and adoption with hands-on delivery experience across real Japan-facing engagements.
Track Record
10+ years, 40+ engagements across SaaS, consulting, healthcare, retail, entertainment, and cross-border B2B.

What we believe
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.
