ActEvolve

ActEvolve Inc. (株式会社ActEvolve) was a Tokyo virtual-reality entertainment company incorporated on 9 August 2017 by Takuya Kato, a former Capcom game developer, together with other ex-game-industry engineers. In November 2018 it launched VARK, a VR live platform on which VTuber and virtual-artist performances — most visibly the long-running "Cinderella switch" series with hololive — were staged as ticketed, seat-based concerts for Meta Quest, Android and iOS, paid for with in-app VARK Coin. The company took strategic investment from KLab Inc. in August 2019, renamed itself VARK Inc. (株式会社VARK) on 1 May 2020 alongside a roughly ¥200M round from ANRI, raised a further ¥600M in May 2021, and diversified into the VARK SHORTS 3D animation tool and the STAR BLOOM liver-management agency, producing metaverse events for ANYCOLOR, Avex, KADOKAWA, COVER, Dwango, Shochiku and Meta. VARK was a consumer entertainment app rather than a platform business: it never operated a developer program, and no public API, SDK, webhook catalogue or machine-readable specification (OpenAPI, AsyncAPI, GraphQL SDL, MCP manifest, agent card) was published on any of its hosts at any point — 1,812 archived URLs across vark.co.jp and its subdomains contain no /api, /developers, /docs, /openapi or /graphql path of any kind. The VARK metaverse service shut down on 4 March 2024 with same-day notice, refunding unused VARK Coin until 5 May 2024 under Japan's Payment Services Act; the free tier of VARK SHORTS ended on 30 September 2024; and in March 2025 the entire company was sold in an all-share transaction whose acquirer and terms were kept confidential, with founder Takuya Kato stepping down as representative director. This profile is retained as a historical record — there is no API surface to enrich.

ActEvolve is profiled on the APIs.io network. Tagged areas include Company, Defunct, Acquired, Virtual Reality, and Metaverse.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, 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/actevolve: open an issue to ask a question, or submit a pull request to add artifacts.

x-shutdown-note: The VARK entertainment-metaverse service was announced and terminated the same day, 4 March 2024, with unused
  VARK Coin refundable until 5 May 2024 under Japan's Payment Services Act. VARK SHORTS lost its free tier on 30 September
  2024. In March 2025 all shares in the company were transferred to an undisclosed buyer and the founder stepped down; the

  last updated 2025-10-17) and actevolve.com is still registered via GoDaddy on Route 53 name servers (created 2017-05-31,
  expiring 2027-05-31), but neither zone publishes an A, AAAA or CNAME record for any web hostname — authoritative queries
  return NOERROR/NODATA and curl exits 6 on every request. The vark.co.jp SOA serial decodes to 2025-03-06, the month the
  sale closed, and the only surviving record is an MX pointing at Google Workspace. corp.vark.co.jp (the corporate site) was
  last captured by the Wayback Machine on 2025-02-09. No host is wired as a Website pointer because none of them serves anything,
  and the EquityZen page this company was harvested from is a trading venue's listing, not a company web presence (roadmap#56).

  detail: ActEvolve/VARK shut its VR platform down on 4 March 2024 and was sold outright in March 2025; vark.co.jp, corp.vark.co.jp
    and actevolve.com are all still registered to the company but publish no A/AAAA/CNAME record, so curl exits 6 ("could
    not resolve host") before any HTTP request can be made, and 1,812 archived URLs from when the sites were live contain
    no /api, /developers or specification path of any kind.
