TenderB OS is the AI operating system for tender teams. It finds relevant tenders, reads the complete tender dossier, and helps you write and check your response. An AI agent knows your company and your tender.
How TenderB OS works
TenderB OS combines a strong language model with the things a tender needs:
Tender logic: award criteria, knock-outs, evaluation methods and bid/no-bid decisions against your company profile.
Procurement data: public tenders from sources in the EU, UK and US, including TED and TenderNed.
Your knowledge: company documents, references, CVs and previous bids, stored in collections.
Guidance: TenderB OS guides your team through every step, from bid/no-bid to submission.
Traceability: you can see which source a paragraph is based on.
The language model is the same kind you know from ChatGPT, Claude or Gemini. What wins a tender is in the layers on top.
What you can do
Find tenders automatically with Scouts.
Decide bid/no-bid quickly, checked against your profile, the knock-outs and the award criteria.
Build a compliance matrix from the full dossier: requirements, knock-outs and deadlines.
Write and score answers against the award criteria, with a source per paragraph.
Reuse your best work with Skills.
Track outcomes: won, lost, contract value and time saved per tender.
Workspaces, projects and collections
A workspace holds your team, members, integrations and settings. A project is one tender or client opportunity. It has its own files, documents, conversations and members. A collection is a library of knowledge, such as your Company Knowledge, that you can attach to projects.
