Diligio vs Responsive (formerly RFPIO)
The enterprise incumbent, compared with a flat-rate, verification-first alternative.
Responsive, which most people still call RFPIO, is the established enterprise platform for RFPs, RFIs, DDQs, and security questionnaires. It has the broadest content and integration feature set of anyone on this list. Diligio is the leaner choice: one flat price, and a second model that checks every answer before it goes out. The real question is whether you need everything Responsive does, or just want that quality of output without the enterprise contract.
At a glance
Competitor details are publicly reported as of June 2026. Neither vendor publishes an official rate card, so pricing is hedged and dated.
Where Responsive is strong
- The broadest content-management and library-governance feature set in the category.
- A deep catalogue of integrations (CRM, collaboration, and content tools).
- Mature reporting, roles, and workflow tuned for large, dedicated bid teams.
- A long track record across RFPs, RFIs, DDQs, and vendor security questionnaires.
Where Diligio is different
Pricing you can read before a sales call
Responsive is sold by custom quote with no public rate card; third parties report an average around $13,900/year and AI features that are often metered separately. Diligio publishes one flat licence of $7,499/year that already includes the AI, SSO, and API, so you can budget without a procurement cycle.
A second model checks the work
Both tools draft answers for a human to review. Diligio adds a step in between: a second model, from a different provider, checks each claim against your source documents and holds back anything it cannot support. On a DDQ or a security questionnaire, that check is worth more than raw speed.
Less to operate
Responsive rewards a dedicated team that invests in library governance and integration setup. Diligio is designed to be useful in days: upload your past proposals and compliance documents, and it extracts and grounds answers without a months-long rollout.
EU data residency by default
Diligio stores customer data at rest in the EU (AWS Paris, plus an EU Supabase), which is often a fixed requirement for European buyers. Responsive offers enterprise region options but does not publicly specify a default.
Who should choose which
Choose Responsive if
you run a dedicated proposal team, push very high volume, need deep integrations, and have the budget and headcount to keep a large library governed.
Choose Diligio if
you want enterprise-grade answers and built-in verification, but not the enterprise contract, the long rollout, or the per-seat maths.
Frequently asked questions
Is Diligio a good Responsive (RFPIO) alternative?
Yes, particularly for teams that want predictable flat pricing and built-in answer verification rather than a large, sales-led enterprise contract. Diligio covers RFPs, RFIs, DDQs, and security questionnaires, drafts answers grounded in your own knowledge base, and independently verifies them before you see them.
How much does Responsive (RFPIO) cost?
Responsive does not publish pricing; it is sold by custom quote. Third-party sources reported an average of roughly $13,900 per year as of 2026, within a range of about $7,000 to $28,000, with AI capabilities often charged separately. Diligio is a flat $7,499 per year with AI, SSO, and API included.
What is the main difference between Diligio and Responsive?
Responsive is a broad enterprise content-and-workflow platform priced by custom quote. Diligio is a flat-priced, verification-first tool: a second independent model checks every drafted answer against your sources and withholds weak ones, which matters most for due-diligence and security questionnaires.
