Tendium

Tendium is a web and API platform for suppliers pursuing public-sector procurement. Its Find product monitors tenders across European markets and applies filters to surface relevant opportunities. Executive AI summaries, document keyword search, and access to tender documents, updates, and award decisions are listed for Sweden, Norway, and Finland. BidFlow adds a Smart Checklist for bid qualification, a Writing Assistant that drafts responses from a reusable Content Library, and tools for colleague comments, deadlines, and progress tracking. The platform also covers tender document management and compliance tracking. Tendium lists TLS 1.2, hashed passwords, encrypted data, hourly core-storage backups, and daily backups for other storage. Security controls include activity and access logs, access controls, SAML/SSO, and two-factor authentication. The Light plan costs €125 a month and includes unlimited users, one tender filter, intelligent search, AI summaries, and tender documents, updates, and awards.
