From problem to product

Meet BudOS.

BudOS supports construction companies throughout a tender: discovery and document analysis, the decision to bid, cost estimation and bid preparation. Explore the product in a public demo based on a real tender, without creating an account.

  1. Discovery and documents

    Explore a tender and review its documentation within one workflow.

  2. Decision and estimate

    Move from assessing the opportunity to preparing a cost estimate. Your team decides whether to bid.

  3. Bid preparation

    Continue the process using the information gathered and the decision your team has made.
