General Manager

Spider Labs is hiring a full-time General Manager to lead its Japan business and report to the CEO as a member of the executive board. The role is positioned as the effective business head for Japan, rather than a branch or single-department manager.

The GM owns the Japan P&L and is accountable for revenue across direct sales, agency sales, expansion and tech-touch channels, as well as gross margin and the GTM budget covering sales, marketing and customer success. The role leads an integrated GTM organization spanning sales, marketing, customer success and inside sales, and builds the next stage of growth. Responsibilities include refining agency-channel strategy and scaling customer acquisition through marketing, using domain knowledge of the advertising industry and measurement technology.

The role presents Japan business results and numerical accountability directly to the board and investors. It also works with the global management team, participates in monthly executive meetings conducted in English, and brings Japanese-market requirements into the global product roadmap. People-management responsibilities cover hiring, development, evaluation and organizational culture for an organization of several dozen people. A handover period with the CEO and CTO is planned after joining, covering investors, key customers, agency partners and the organization.

The product is Spider AF, a SaaS platform that protects advertisers and agencies from ad fraud, including fraudulent clicks, fake leads and invalid traffic. The product has been adopted by major banks, major cosmetics brands and category-leading e-commerce companies. Spider Labs has a global team of about 80 people, with locations in Tokyo, New York and Lisbon; the Lisbon location handles R&D and engineering. The company is expanding detection technology for the AI-agent era and plans a full-scale monetization effort in the US market.

This is a full-time position at the Tokyo office in Minami-Aoyama. At least four office days per week are required, with one day working from home, and the posting targets people living in the Tokyo metropolitan area. The start date is negotiable. Compensation is determined according to experience, skills and results, with stock options granted. Business-level Japanese and English are required.
