ABABA

ABABA (株式会社ABABA) is a Tokyo-based Japanese HR technology company operating a new-graduate direct-recruiting platform built on an unusual premise: only students who have already reached the FINAL interview stage at another company may register, and each submits evidence of that selection history, so every candidate in the database arrives pre-qualified by someone else's hiring bar. Employers then scout those near-miss finalists into abbreviated selection flows — the company reports that 94% of adopting employers waive the entry sheet or the first interview for an ABABA candidate. A second product, REALME, runs AI mock interviews and matching. Founded 19 October 2020 and led by co-representatives Shunki Kubo (CEO) and Tatsuya Nakai, ABABA raised a 1.25 billion yen Series B in March 2025 led by DBJ Capital (1.82 billion yen total to date) and reported passing 3,000 cumulative adopting companies in November 2025. The product ships purely as an end-user web application: ABABA publishes no developer portal, API documentation, SDK, webhook catalog or machine-readable specification of any kind.

ABABA is profiled on the APIs.io network. Tagged areas include Company, Human Resources, Recruiting, Talent Acquisition, and HR Technology.

ABABA’s developer surface includes engineering blog and 6 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Employment & Payroll regime (on an ambiguous tag, where no other regime matched), so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ababa: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: 'ABABA runs two real first-party hosts — a Bubble.io end-user application at ababa.co.jp whose robots.txt is Disallow:/
    for every user agent, and an undocumented Go API at api.ababa.co.jp (AWS ap-northeast-1, permissive CORS, /health 200)
    that backs it — but the company publishes no developer program at all: every OpenAPI/Swagger/GraphQL/agent-card/apis.json
    path on all three hosts 404s against a clean negative control, api./docs./developer subdomains either 404 or do not resolve,
    and the corporate site''s own sitemap lists only company, article, whitepaper, news, privacy and job-posting-policy routes
    with nothing developer-facing.'
