Leach Co., Ltd. (Headquarters: Minato-ku, Tokyo; CEO: Takuya Tominaga) exhibited and participated in a pitch contest at 'TakeOff Tokyo 2026', one of Asia's largest startup conferences, held at the Tokyo Big Sight South Hall from March 31 to April 1, 2026.
TakeOff Tokyo is a premier Asian conference bringing together startups, investors, and business corporations from around the world, centering on the Asia-Pacific region. This Tokyo edition featured a 50-company pitch contest, exhibition booths, networking sessions, and keynote speeches over two days. For details, please refer to the 'About TakeOff Tokyo' section later in this release.
While many companies offer AI technologies, few deeply integrate into field workflows to automate daily operations, making Leach's business model a highly evaluated differentiator. CEO Tominaga is an engineer who spent 9 years at the Toshiba R&D Center, participating in joint projects with Google Cloud and McKinsey, giving him firsthand experience in large corporate environments. He possesses top-tier domestic technical prowess, having acquired all 12 AWS certifications in about a month, alongside an R&D track record as the inventor of patent No. 7086873. The combination of this technical background and operational understanding contributed to the persuasiveness of his pitch.
Product Overview of Saturn and Totsugo.com
The proprietary product 'Saturn' is an AI quote and billing automation tool available from 30,000 yen per month. It fully automates the order-to-billing flow between COREC and freee using a spreadsheet UI. AI automatically matches item name variations, with case studies showing transcription work that took 8 hours a day compressed to 10 minutes. 'Totsugo.com' enables an AI primary check for matching hundreds of PDF pages against hundreds of others, realizing a workflow where humans only need to press the Enter key repeatedly to confirm, streamlining tasks to be completed in 30 minutes by one person.
In addition, the company offers several solutions as industry-specific AI business OSs:
- FactoryOS: For high-mix low-volume manufacturing
- FestOS: For food event and festival management
- BuildOS: For equipment leasing businesses
- RecruitOS: For recruitment agencies
- LogiOS: For small to medium transportation companies
- WasteOS: For industrial waste disposal operators
- LeachOS: For executives, sales, and marketing
CEO Takuya Tominaga is an engineer with an R&D background who worked at the Toshiba R&D Center for 9 years. His major awards and certifications include:
- Acquired all 12 AWS Certifications in about 1 month (among the fastest in Japan)
- Inventor of Patent No. 7086873
- DICOMO 2014 Best Presentation Award and Excellent Paper Award (as a graduate student, ranked 1st out of 293)
- IPSJ DPSWS 2014 Excellent Poster Award
- 2nd place in the University of Tokyo joint development 'Toshiba version AI Engineer Education Program'
- Tutorial Instructor at the 42nd JSSST Annual Convention (2025)
Driven by the awareness that 'even as technology advances, field operations remain unchanged,' he transitioned from corporate R&D to a startup, contributing to business automation for SMEs.
Furthermore, the company has received high praise from domestic and international startup support programs, as well as academic and public institutions, including selection for Cloudflare for Startups, E2B for Startups, and the Tokyo Metropolitan Acceleration Program, and an appointment as an invited instructor for JSSST. The press release introduces specific implementation results featured in national and industry papers, such as 'A technical advisor you can consult on a time-charge basis like a lawyer is almost non-existent in the market' - case study with Mizunara Co., Ltd., '20,000 order checks annually, reduced from three people to one' - case study of Nabel Co., Ltd. x Leach Totsugo.com, and '90% reduction in shipping label creation man-hours' - Rikiman Co., Ltd. x Leach Generative AI Advisor implementation.
In a message, CEO Tominaga stated, 'I am convinced that generative AI will dramatically change business operations.' He views it as his mission to transform the analog field remaining in Japanese SMEs using generative AI, helping those who match documents by looking at a monitor with a ruler or repeatedly copy and paste manually. Reflecting on the participation, the CEO said, 'Broadly broadcasting the presence of Leach as a generative AI startup through pitching and exhibiting at Asia's largest startup conference will be a major catalyst for future business expansion, talent acquisition, and fundraising.' Moving forward, Leach will resolve SME labor shortages and back-office inefficiencies with generative AI, promoting DX in Japan's back offices through the provision of industry-specific AI business OSs.
