atena株式会社

atena株式会社 operates "atena" (クラウド郵便), a cloud-based postal mail management service in Japan. Customers who register receive a dedicated atena mailing address to which their postal mail can be sent; as an option, atena can also collect mail from a customer's existing mailbox or post box. Incoming items are first notified unopened, with the exterior of the envelope and the sender's name shown to the recipient via chat (Slack), email or the web interface. From there the user chooses in one click whether the item is opened and converted to PDF, forwarded, or disposed of. Held mail is consolidated and forwarded to a designated address twice a month, with on-demand forwarding also available.

The product includes search and filtering by sender or contents, team separation with permission settings, and an activity log allowing comments and a history of operations on each mail item. For employee-addressed documents such as insurance cards, addresses can be selected from HR systems including SmartHR rather than entered manually. Stated turnaround times are digitization and notification within 24 hours of collection, PDF conversion within 24 hours of request, and same-day dispatch for forwarding requests placed by 15:00 on business days.

atena is a group company of 株式会社kubell, which is listed on the Tokyo Stock Exchange Growth market. On security and compliance, the company states it operates an information security management system and holds ISO/IEC 27001:2022 certification, and that stored mail is kept in a facility with multi-level biometric entry control, surveillance cameras recording 24/7 and constant guarding.

Business model

Subscription SaaS-plus-operations model: a monthly base fee covers a set volume of mail handled at atena's facility, with usage-based charges beyond that and paid options for mailbox collection. Contracts run on monthly renewal with no minimum term, cancellable by notice before the end of the prior month, and payment is by credit card.

Recurring monthly fee of JPY 15,000 (excluding tax) for up to 50 items per month, with PDF conversion included at no charge (JPY 0 per item), JPY 200 per item above 51 items, and JPY 500 per item for ad-hoc forwarding. Mailbox collection is an additional option priced by pickup location and frequency, and cases requiring physical keys or building entry procedures incur extra fees. The site also advertises a monthly price of JPY 15,000 for the core service.

Traction

The company states that more than 1,000,000 mail items in total have been digitized for customers spanning listed companies to individual proprietors, and presents adopting-company logos and case studies covering business continuity planning and work-style reform outcomes.
