thinkjam（株式会社シンクジャム） is a Tokyo-based marketing planning agency founded in 2009. Its official positioning is “turning all data into content.” The company mainly serves high-ticket and conversion-driven categories with long decision cycles and multiple stakeholders, including housing, finance and insurance, healthcare, beauty, B2B manufacturing, and IT consulting.
Its offering is not a standalone SEO tool, but an integrated mix of consulting, content, and execution. On the awareness and acquisition side, it provides SEO/LLMO design, advertising planning, landing page production, SNS operations, and campaign planning. On the conversion side, it supports form optimization, white papers, and original downloadable materials. For relationship management, it covers email, LINE, SNS, and apps. In terms of data capabilities, thinkjam supports GA4 event setup, access log analysis, Looker Studio visualization, MA implementation and operations, customer clustering, and content strategy built from surveys, interviews, SNS research, and competitor analysis.
The official website does not disclose packages, starting prices, or price ranges. It appears to be primarily project-based consulting and production work, making it more suitable for companies with budgets that can be assessed and customized case by case. Integration information is relatively clear: website development can support WordPress, Movable Type, and Drupal; MA tools mentioned include SATORI, HubSpot, and Salesforce; analytics involve GA4 and Looker Studio. The company can also handle LINE data integration, proprietary tools, and AI/MA integrations.
The main advantage is full-funnel coverage, from strategy, KPIs, content, and production through to data analysis and PDCA improvement. It also has a clear methodology for customer journeys, value propositions, and content expression in complex product categories. The website provides relatively detailed information on client industries and companies, and the firm has obtained ISMS certification. The drawbacks are limited pricing transparency, making it hard to assess cost-performance before procurement; it is closer to a customized consulting and production team than a standardized SEO monitoring software provider. With 27 employees and 7 consultants, its capacity for very large-scale parallel delivery should be confirmed separately.
thinkjam is better suited to medium and large enterprises targeting the Japanese market, B2B marketing teams, brand/recruitment teams, and high-ACV businesses that need to turn data insights into content and leads. Access from China cannot be confirmed from the available text. Chinese companies considering cooperation should factor in Japanese-language communication, cross-border payments, contracts, and differences in the local media ecosystem. If the main target is the Chinese market, it would also be worth evaluating local SEO agencies, content marketing agencies, or HubSpot ecosystem service providers.
