Cobrief is an AI-powered tender management platform that helps businesses find, evaluate and respond to public procurement opportunities. The platform covers the full bidding workflow โ€” from tender discovery and automated notifications to AI-assisted proposal writing and price sheet filling.

Cobrief monitors public tenders published on TED (Tenders Electronic Daily), Doffin (Norway), Udbud (Denmark) and other national procurement databases across the Nordics and Europe. Users receive real-time notifications of relevant opportunities via email or Slack, filtered by industry, CPV codes and keywords.

The platform's AI reads and analyzes complete tender documents, extracting key requirements, qualification criteria, deadlines and evaluation weights onto a single structured page. Every AI-generated claim links directly to its source in the original documents. Based on this analysis, bid teams can make faster go/no-go decisions and generate first drafts of proposal responses up to 80% faster than manual writing.

Additional features include automated price sheet filling, CV matching for competency-based tenders, competitor analysis and market insights based on 10 years of historical procurement data.

Cobrief is used by over 2,000 companies ranging from small businesses to large enterprises such as Knowit, Randstad, Hafslund, Oda, Lyreco, Tietoevry and Compass Group. The platform serves the Norwegian, Swedish, Danish, Finnish and German public procurement markets.

Founded in 2023 and headquartered in Oslo, Norway, Cobrief is founder-owned, ISO 27001 certified and GDPR compliant. All customer data is stored and processed within the EU/EEA, encrypted in transit and at rest, and AI models are never trained on customer data. Cobrief won Virke's Innovation Award in 2025.

  • Designed for Legal Professionals
    The platform is specifically tailored for the legal industry, meaning its features and workflows are built with lawyers and legal teams in mind, rather than being a generic AI tool adapted for legal use.
  • Time and Cost Efficiency
    By automating repetitive legal tasks such as research and document review, Cobrief can help law firms and legal departments reduce the time spent on manual work, leading to cost savings and improved productivity.
  • User-Friendly Interface
    Cobrief appears to offer a clean and accessible interface designed to make AI tools approachable for legal professionals who may not have deep technical expertise, lowering the barrier to adoption.

React Complex Tree features and specs

  • Customizability
    React Complex Tree offers a high degree of customizability, allowing developers to tailor the tree component to fit their specific needs. This can be especially useful for creating unique UI experiences.
  • Feature-Rich
    The library includes a wide range of features out of the box such as drag-and-drop support, keyboard navigation, and dynamic data loading, which can save development time.
  • Accessibility Support
    React Complex Tree is designed with accessibility in mind, providing support for ARIA attributes and keyboard interactions, which helps ensure that applications are usable by people with disabilities.
  • Performance
    The component is optimized for performance, handling large data sets efficiently without significant slowdowns, which is critical for applications that manage extensive hierarchical structures.
  • Community and Documentation
    The library has a supportive community and well-structured documentation, providing developers with ample resources to troubleshoot and extend its functionality.

Possible disadvantages of React Complex Tree

  • Complexity
    Due to its extensive features and customizability, React Complex Tree can be complex to set up and configure properly, which may lead to a steeper learning curve for new users.
  • Bundle Size
    As a feature-rich component, React Complex Tree can increase your bundle size, which might be a concern for projects where performance and loading time are critical.
  • Third-Party Dependency
    Relying on a third-party library introduces dependencies outside of your control, which may present challenges in terms of long-term maintenance and potential update or deprecation issues.
  • Specific Use Case Tailoring
    While it offers a lot of features, developers may find that very specific use cases require additional effort to customize or extend the component beyond its intended use.

Questions & Answers

As answered by people managing Cobrief and React Complex Tree.

Why should a person choose your product over its competitors?

Cobrief's answer

Cobrief lets you get started in 3 minutes with no training required, while most competitors require onboarding, implementation or setup calls. Tender notifications are included free on all plans, removing the paywall that others charge for. The AI drafts proposal responses up to 80% faster, fills price sheets automatically (saving 5x the time), and matches CVs from your team to tender requirements 10x faster. With 1,500+ companies already using the platform and customers like Knowit, Randstad, Hafslund, Oda and Lyreco, Cobrief is proven at scale across industries. We are also founder-owned, built and designed in Norway, and winner of Virke's Innovation Award 2025.

How would you describe the primary audience of your product?

Cobrief's answer

Bid managers, sales leaders and commercial directors at small, medium and large companies that sell goods or services to the public sector. Our customers range from one-person firms bidding on their first tender to large enterprises like Compass Group managing 300+ tenders per year. The platform is used across industries including IT consulting, staffing, facilities management, construction, healthcare and retail. Cobrief currently serves the Norwegian, Swedish, Danish, Finnish and German public procurement markets.

What's the story behind your product?

Cobrief's answer

Cobrief was founded in 2023 with a simple observation: public procurement is worth over โ‚ฌ800 billion annually in the Nordics and Europe, yet the process is bureaucratic, time-consuming and inaccessible โ€” especially for small and medium-sized businesses. On average, only two suppliers bid on each public tender, meaning governments aren't getting the best value and suppliers are missing out on opportunities. Cobrief was built to change that. By automating the tedious parts of tender work with AI, we level the playing field so companies of all sizes can compete. Our vision is to become the world's leading tender platform โ€” one that brings forward the best suppliers.

Which are the primary technologies used for building your product?

Cobrief's answer

Cobrief is built as a modern cloud-native SaaS platform. The AI layer uses large language models for document analysis, requirement extraction and proposal drafting. The platform integrates with CV Partner for competency matching and supports notifications via email, Slack and Microsoft Teams. Cobrief is ISO 27001 certified, all customer data is encrypted in transit and at rest, and AI models are never trained on customer data.
