Why This Position Exists
This executive position is being created due to an executive team restructuring (division of labor) to accelerate business expansion.
Previously, the Co-Founder & CTO acted as the Integrator, overseeing all execution across the company (Product, Sales, Marketing, CS, Corporate). To speed up growth, these responsibilities are being separated:

• CEO: Focuses on overall vision and long-term global strategy.
• CTO: Focuses on product development, R&D evolution, and increasing delivery speed.
• GM, Japan (This Role): Takes full responsibility for decision-making and leading the entire Japan business (P&L, Organization, GTM Strategy), which generates the vast majority of revenue.

Rather than a typical branch manager or functional head, you will lead as the "de facto executive head" of the core Japan business. A thorough handover period with the CEO/CTO will be provided upon joining (covering investors, key clients, agency partners, organization, etc.).

About Spider Labs

• Track Record & Scale: Adopted by major banks, leading cosmetics brands, and e-commerce category leaders. Global team of ~80 employees.
• Offices: Tokyo (HQ), New York, Lisbon (R&D/Engineering).
• Future Outlook: Expanding next-generation detection capabilities for the AI agent era, alongside full-scale revenue expansion in the U.S. market.

Your Mission

• Full Ownership & Management of Japan P&L: Optimize revenue, gross profit margin, and Go-To-Market (GTM) budgets (Sales, Marketing, CS) across all channels (Direct, Agency, Expansion, Tech-Touch). Directly report results and take accountability for Japan's performance to the Board of Directors and investors.
• Lead the GTM Organization: Integrated management of Sales, Marketing, Customer Success, and Inside Sales to build the next growth curve.
• Deepen Agency Strategy & Scale Acquisition via Marketing: Update channel strategies utilizing deep domain knowledge in ad tech, measurement, and the advertising industry.

• Organizational Development & People Management: Manage hiring, development, performance reviews, and culture building for an organization of several dozen employees.

We Are Looking For

• Nationality & Japanese Language Proficiency:
  • Open Nationality: What matters most is being rooted in the Japanese market; passport nationality is irrelevant. Native English speakers are welcome.
  • Japanese Proficiency: Business-level Japanese (does not need to be native level) is required to build strong, trusting relationships with agency and client CXOs.
• Executive Team & Culture:
  • CEO (Founder): Values fast-paced, open communication. Heavily integrates AI tools into daily workflows. Prefers high accountability and speed without micro-management.

  • Those who rely heavily on corporate resources, brand power, or corporate back-office infrastructure.
  • Individuals hesitant to conduct high-level business discussions in English.
