About 3-shake

3-shake Inc. is a Japanese technology company founded in January 2015 by Takuma Yoshida, who serves as the CEO. The company's name is derived from the 'three-way handshake,' a network technology term, reflecting its mission to provide foundational services that accelerate innovation.

Yoshida, a graduate with a Master's in Quantum Engineering from the University of Tokyo, began his career as an infrastructure engineer at DeNA in 2011. His experience with AWS and a subsequent role at a startup, Poppin Games Japan, inspired him to establish 3-shake to create an infrastructure platform originating from Japan. He started the company from his home, initially offering AWS construction and operation support.

3-shake operates with a multi-product and hybrid business model, focusing on resolving engineering challenges in infrastructure, security, data, and human resources. The company's core mission is to 'simplify infrastructure to create a world where innovation can easily occur.' It has seen significant growth, raising a total of 500 million yen in a Series A round in January 2021, 848 million yen in a Series B round in August 2022, and securing a 1 billion yen capital and business alliance with NTT Data and SCSK in November 2024.

The company offers four main services: * **Sreake**: Launched in August 2018, Sreake is a comprehensive Site Reliability Engineering (SRE) consulting service. It supports clients with technology strategy, design, development, and operation, specializing in AWS, Google Cloud, and Kubernetes. The service aims to help clients build self-sufficient, top-tier infrastructures. * **Reckoner**: Introduced in January 2020, Reckoner is a no-code, cloud-based data integration platform (iPaaS). It enables users to easily transfer and process data, connecting various sources like databases, storage, and SaaS applications to build data foundations for business analysis and marketing. Reckoner is a Google Cloud Partner. * **Securify**: Initially launched as 'Sreake Security' in May 2020 and later rebranded, Securify is a security service that includes an automated vulnerability assessment tool. It provides an Attack Surface Management (ASM) and vulnerability diagnosis to identify and manage security risks. * **Relance**: Launched in December 2020, Relance is a recruitment and staffing service specializing in freelance IT engineers. Leveraging the company's own engineering expertise, Relance aims to accurately assess candidate skills and match them with suitable projects, while also offering support for building internal engineering teams.

3-shake primarily serves B2B clients, ranging from large corporations like NTT Data, Toyota, and JCB to startups. Its business model combines consulting services (Sreake) with SaaS products (Reckoner, Securify) and a human resources platform (Relance).
