Tenderbolt
Tenderbolt is an AI platform for preparing responses to RFPs, RFQs, and public tenders. It extracts requirements, deadlines, penalties, and scoring criteria into a structured qualification summary. For Excel questionnaires, DDQs, and security portals, it drafts answers from a company knowledge base. It can generate technical proposals aligned with client requirements and link proposal sections to source documents. Teams share a workspace for assigning questions, reviewing answers, tracking validation, and managing tender work. The content library accepts PDF, Word, Excel, and PowerPoint files, and responses can be returned in a client's original format. Listed integrations include SharePoint, Google Drive, Notion, CRM and ERP tools, and a REST API. Tenderbolt says data is hosted in Europe, encrypted, isolated in private workspaces, and not reused to train shared or public AI models. Missing information is flagged rather than invented. Pricing is tailored to team size and RFP volume; prospects can book a demo.
