Company profile
researched Aug 2026株式会社カイマク (Kaimaku Co., Ltd.) is a Tokyo company that builds business services around a fully performance-based (成果報酬) fee model, summarised by its tagline "performance-based solutions for every business." Its corporate profile lists HR platform business as its line of business, with capital of 52.21 million yen and Rei Oshima (大島 黎) as representative director.
The company operates four service lines. HR Shodan Bank (人事商談バンク) is a fully performance-based appointment-setting service for the HR sector, drawing on a continuously updated database of recruitment-related information on more than 70,000 companies nationwide to approach decision-makers at firms with hiring needs, with no upfront fee. CEO Shodan Bank (社長商談バンク) applies the same model to appointments with company presidents and executives across company sizes and industries. CEO Connect (CEOコネクト), described as in preparation for launch, is a screened, membership-based matching platform for executives to find partnership, collaboration and business-development opportunities through both online and offline touchpoints. Tech Farm (テックファーム) is a high-payout SES (engineer staffing) business focused on startups and growth industries, offering an 83% payout rate linked to billing rates, an 89% share of fully remote assignments, project self-selection by engineers, and a reported average annual salary increase of 1.65 million yen on joining.
Kaimaku is a group company of Aidma Holdings Inc. (株式会社アイドマ・ホールディングス), listed on the Tokyo Stock Exchange Growth Market under securities code 7373.
Founding story
Founder and representative director Rei Oshima previously worked as a UI/UX designer collaborating closely with IT engineers and, through recruitment- and branding-support work, handled many SES companies. Concluding that industry structure and company-first practices constrained engineers' careers — opaque pay design, mostly on-site assignments, no choice of projects and limited access to new technologies — he launched Kaimaku Tech Farm to address those issues. The 複業 referral programme drew on his earlier involvement in launching the service 複業クラウド.
Business model
Kaimaku sells outsourced sales/appointment-setting on a fully performance-based basis, charging client companies only when a qualified meeting with a decision-maker is generated, with no initial fee. Alongside this it runs an SES engineer-staffing business (Tech Farm) that places employed engineers on client projects and returns 83% of the billing rate to the engineer, and it is preparing a membership-based executive matching platform (CEO Connect).
Success-fee (performance-based) charges for appointments and sales meetings delivered to client companies; staffing revenue from engineer placements under the Tech Farm SES business, priced on client billing rates with an 83% payout to engineers.
Traction
The site reports cumulative appointments generated of more than 10,000, customer satisfaction of 96.8%, a mid-contract cancellation rate of 0.12%, and 250,000 outbound calls per month. HR Shodan Bank surpassed 70 client companies in February 2025. Announced client results include 400 meetings and over 100 orders within five months at Thanks Lab, more than 20 appointments in the first month at Def Works, and 200% growth in monthly meetings at Innovel.
Latest developments
In November 2025 Kaimaku announced deployment of HR Shodan Bank at Def Works, which operates the YATTOITE! recruitment-support service, reporting more than 20 cumulative appointments in the first month of operation. CEO Connect, an executive-to-executive matching platform, is listed as in preparation for release, and the company is actively hiring engineers, sales/career advisors and new-business leads.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
Positions itself in Japan's outsourced sales/appointment-setting market as a fully performance-based provider specialised by buyer segment (HR-sector decision-makers, company presidents), and in the SES market as a high-payout, engineer-first alternative to conventional staffing firms in an industry the company describes as comprising roughly 15,000 Japanese companies.
Complete performance-based pricing with no initial fee; verticalised targeting of HR-sector and CEO decision-makers backed by a 70,000-company recruitment-information database; in the staffing business, an 83% payout rate, project-selection rights for engineers, a high share of fully remote assignments, and a "複業" (multiple main jobs) referral programme enabling engineers to take 0.2–0.5 person-month side assignments to learn new technologies.
Technology
A proprietary database that collects and updates recruitment-related information on more than 70,000 companies in real time supports targeting of decision-makers. Company interviews describe the use of in-house AI systems for project matching and sales activity to raise proposal volume and internal efficiency.
Go-to-market
Direct outbound calling at scale (reported 250,000 calls per month) by sector-specialised teams, offered to clients with zero upfront cost, plus press releases publicising client results; engineer recruiting for the SES arm is marketed on remote work, project choice, side-project referral and individual-development support programmes.
Japanese companies selling into the HR/recruitment sector and companies seeking meetings with SME-to-large-enterprise presidents and executives; on the supply side, IT engineers seeking remote work and higher compensation. Named client companies include Def Works, Thanks Lab (サンクスラボ) and, per press listings, ProReach, Innovel and Getsuraku.
Geography
Japan. The corporate site lists a head office in Ebisu-nishi, Shibuya-ku, Tokyo; a third-party company profile lists an address in Ginza, Chuo-ku, Tokyo. Remote engineer placements are described as available nationwide, including cases such as an employee living in Sapporo working on a Nagoya project.
History
The company was established on 2020-11-27. Press coverage records client deployments through 2024 (ProReach, Innovel, Getsuraku). In February 2025 it announced that HR Shodan Bank had passed 70 client companies; in March 2025 it formally launched CEO Shodan Bank; in May 2025 it announced a deployment at Thanks Lab; and in November 2025 a deployment at Def Works. CEO Connect is listed as coming soon. The company is part of the Aidma Holdings group.
Risks & controversies
Performance metrics such as satisfaction rate, cancellation rate, payout rate and average salary uplift are self-reported by the company. Address information differs between the company site (Shibuya-ku) and a third-party profile (Chuo-ku), and the SES model exposes the staffing business to client project demand and to the industry restructuring the founder anticipates.
