Strutter vs RFPIO: Which RFP Tool Is Actually Built for Buyers?

RFPIO built its business on a real problem: responding to RFPs is slow, repetitive, and painful for vendor teams. Content gets rewritten from scratch for every new RFP. Answers live in someone's email. The proposal goes out at midnight before the deadline.

RFPIO (now rebranded as Responsive) solved that for vendors. It is a response management platform with a content library, AI auto-fill, and collaboration tools for proposal teams.

None of that helps buyers.

If you are on the procurement side, creating RFPs and evaluating vendor responses, RFPIO was not built for you. Strutter was.

This comparison covers what each tool does, who it actually serves, and where the differences matter.

What RFPIO (Responsive) is

Responsive is a response management platform for vendors. When a vendor receives an RFP, Responsive helps them respond faster by:

• Maintaining a library of pre-approved answers to common questions
• Using AI to match incoming questions to existing library content
• Collaborating across proposal writers, subject matter experts, and reviewers
• Tracking deadlines and managing multiple active proposals

It is good at what it does. Vendors with high RFP volume genuinely benefit from having a content library and automated first drafts.

Built for: Vendors, sales teams, bid managers, proposal writers Primary use case: Respond to incoming RFPs faster and more consistently

What Strutter AI is

Strutter AI is an RFP management platform for buyers. It handles the procurement side of the equation:

• Generating complete RFPs from a plain-language description of your need
• Inviting vendors and providing a structured response portal
• Auto-scoring vendor responses using weighted criteria
• Comparing all vendors side by side
• Generating an AI recommendation with strengths, weaknesses, and trade-offs

Built for: Procurement teams, buyers, RFP issuers Primary use case: Create, manage, and evaluate RFPs from start to award

The core difference

This is what most comparison articles miss: these tools are not competing for the same user. They are built for opposite sides of the RFP process.

A vendor using Responsive can respond to an RFP that was created in Strutter. The tools are complementary, not competing.

Feature comparison

RFP creation

Responsive does not create RFPs. That is not a gap in their product. It is simply not what they do.

Strutter generates a complete, structured RFP from a description like "We need a cloud-based HR platform for 400 employees, replacing ADP Workforce Now." The AI produces questions organized by section, with appropriate question types (multiple choice, table, file upload, free text) and draft scoring criteria.

You edit, add, and remove questions before publishing. The AI is a starting point, not an autopilot.

Scoring and evaluation

This is where the gap between the two tools is largest for buyers.

Responsive does not score incoming RFP responses. It was not designed to. Buyers using Responsive's platform do not really exist. The buyer-side gap is exactly why Strutter was built.

Strutter scores every vendor response the moment it is submitted. Each answer gets a 1-5 score based on how well it addresses the question criteria. Every score includes an explanation. You can override any AI score with one click, and the override is recorded in the audit trail.

After scoring, the comparison matrix shows all vendors side by side, grouped by section. You can filter, sort by weighted total, and expand any score to read the full vendor answer. No spreadsheet required.

Vendor response experience

In Responsive, the vendor is the primary user. The tool is built around their workflow: receive RFP, match to library, draft response, review, submit.

In Strutter, vendors receive a secure submission link. They answer questions in a structured portal, uploading files where needed. The response goes directly into Strutter's scoring system. Vendors do not need a Strutter account, and they can use Responsive or any other tool to prepare their answers before submitting.

The vendor experience in Strutter is clean and simple by design. The complexity lives on the buyer side, where it belongs.
