Sansan

Sansan, Inc. is a Tokyo-based enterprise SaaS company that builds cloud contact- and business-card management software. Its flagship Sansan platform digitizes and centralizes business cards and customer contact data so sales teams can share information across the organization, surface opportunities, and integrate contact data with external systems. The company also offers the Eight business-card app and Bill One invoice-management product. As of this enrichment pass Sansan does not publish a public developer portal, API reference, or OpenAPI definition on its English or Japanese websites; this profile captures the company identity and probed domain-security posture only.

Sansan is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Contact Management, Business Cards, and CRM.

Regulatory Posture applies to this provider. Its tags matched the Payments 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/sansan: open an issue to ask a question, or submit a pull request to add artifacts.
