As answered by people managing StackGo and RFPvault.io.
RFPvault.io's answer:
Three reasons: confidence scores on every AI-drafted response so you know exactly which answers need human review, automated procurement law objections that no competitor offers, and pricing starting at €39/mo - a fraction of what Loopio or Responsive charge per user. It was built by someone who actually responds to RFPs daily, not by a team that read about the problem in a market report.
RFPvault.io's answer:
RFPvault is the only RFP response tool that includes automated procurement law objection generation. It identifies requirements in public tenders that may violate procurement regulations, cites the relevant legislation, and drafts formal objection documents. In one recent tender, 11 of 14 objections were accepted by the procuring authority. No other tool on the market attempts this.
RFPvault.io's answer:
Presales engineers, bid managers, and proposal teams who respond to RFPs and tenders regularly - especially in technology, defense, infrastructure, and public sector procurement. Teams of 1-20 who handle 5+ RFPs per quarter and are tired of rewriting answers that already exist somewhere in the organization.
RFPvault.io's answer:
It started as an internal tool. The founder spent years in presales responding to complex technical RFPs and got tired of spending weeks on each one - copy-pasting from old proposals, chasing subject-matter experts, and formatting Word documents. He built a tool to automate the painful parts and kept using it daily. Colleagues started asking "how do you respond so fast?" - that's when it became a product.
RFPvault.io's answer:
Modern web stack with enterprise-grade security. AES-256 encryption at rest, TLS 1.3 in transit, role-based access control, and full audit logging. Hosted on private infrastructure with edge protection.
