TANAAKK

TANAAKK (タナーク) is a Japanese software company that positions itself around the concept of "Growth-as-a-Service" (GAAS). According to its own corporate history, the business began as a sole proprietorship on 1 December 2006 while the founder was still a student at the University of Tokyo, and the TANAAKK name was adopted in June 2013. The company is headquartered in Tokyo and operates primarily in the Japanese enterprise software market, with a growing presence in the wider Asia-Pacific region. TANAAKK's flagship offering is GAAS (Growth-as-a-Service), a packaged software product launched in April 2021. GAAS is designed to help customers achieve three capital-return objectives: return on invested capital above benchmark, growth, and operating leverage. To that end it bundles resources spanning market research, budgeting, product design, mass production, sales, procurement, legal affairs and financial funding, combining general-purpose platforms to build SaaS products. GAAS is composed of the business-module products within the HITSERIES AI infrastructure. HITSERIES is the company's investment-operations infrastructure and application suite, designed and sold by TANAAKK. It includes a family of packaged software and Infrastructure-as-Code offerings such as HITSERIES RevOps, HITSERIES CICD and HITSERIES SRE, all aimed at increasing intangible-asset value. The company also markets related products and services including HITSCAN, HITPLAN, HITSERIES Capital, HITSERIES Centurion, HITSERIES Centillion, and the ImmuniWeb security portfolio, which TANAAKK distributes in Japan through a partnership with ImmuniWeb. TANAAKK has received local recognition, winning a special award from Chiyoda City in 2021 and the Chiyoda City Mayor's Award in 2022. The company has also been recognized for rapid growth: it recorded a growth rate of +1,672.47% (17.72x) between 2020 and 2023, an average annual growth rate of +160.73% (2.60x), and was ranked second in Japan and 38th in Asia in the Financial Times Asia-Pacific High-Growth Companies 2025 list. TANAAKK remains a privately held company and continues to market its GAAS and HITSERIES offerings to large enterprises pursuing digital transformation and new-business development.

TANAAKK's corporate history traces its origins to 1 December 2006, when the business was started as a sole proprietorship (個人事業) while the founder was enrolled at the University of Tokyo. The TANAAKK name was formally adopted in June 2013. Over the following years the company evolved into a software business focused on enterprise growth and digital transformation. A major turning point came in April 2021 with the launch of GAAS (Growth-as-a-Service), a packaged software offering designed to help customers achieve three capital-return objectives: return on invested capital above benchmark, growth, and operating leverage. GAAS provides comprehensive resources across market research, budgeting, product design, mass production, sales, procurement, legal affairs and financial funding, combining general-purpose platforms to build SaaS products. GAAS is composed of the business-module products within the HITSERIES AI infrastructure. HITSERIES is TANAAKK's investment-operations infrastructure and application suite, designed and sold by the company. It comprises a series of packaged software and Infrastructure-as-Code offerings aimed at increasing intangible-asset value, including HITSERIES RevOps, HITSERIES CICD and HITSERIES SRE. The company also markets related products such as HITSCAN, HITPLAN, HITSERIES Capital, HITSERIES Centurion and HITSERIES Centillion. TANAAKK has also built a partnership with ImmuniWeb, distributing the ImmuniWeb security portfolio in Japan. The company received a special award from Chiyoda City in 2021 and the Chiyoda City Mayor's Award in 2022. It recorded a growth rate of +1,672.47% (17.72x) between 2020 and 2023, with an average annual growth rate of +160.73% (2.60x), and was ranked second in Japan and 38th in Asia in the Financial Times Asia-Pacific High-Growth Companies 2025 list.
