Strutter vs Loopio: A Buyer-Side Perspective on RFP Software

Loopio shows up in most RFP software searches. It has strong reviews, a polished product, and a clear market position. What the reviews often fail to mention: Loopio is a proposal management tool for vendors. If you are a buyer who creates and evaluates RFPs, it is solving the wrong problem for you.

This comparison looks at both tools from the buyer's perspective, covers where they differ, and helps you decide which one fits your actual workflow.

What Loopio is

Loopio is a response management platform. Its core purpose is helping vendor teams respond to RFPs, security questionnaires, and due diligence requests faster.

The product is organized around a content library. Vendors build up a library of pre-approved answers to common questions. When a new RFP arrives, Loopio uses AI to match incoming questions to existing library content, so the response team can assemble a draft instead of starting from scratch.

Loopio also offers collaboration tools for larger proposal teams, workflow management for tracking deadlines across multiple active proposals, and integrations with CRM platforms.

Built for: Vendors, proposal teams, bid managers, sales engineers Primary use case: Responding to incoming RFPs faster with reusable content

What Strutter AI is

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

• Generating complete, structured RFPs from a plain-language description
• Publishing the RFP and inviting vendors to a secure submission portal
• Auto-scoring every vendor response using weighted criteria
• Comparing vendors side by side in a single view
• Generating an AI recommendation with strengths, weaknesses, and trade-offs between finalists

Built for: Procurement teams, buyers, operations and finance teams running RFPs Primary use case: Create, manage, score, and decide on RFPs

Who each tool actually serves

The clearest way to see the difference is in who sits down and uses the software every day.

In Loopio, that person is a proposal manager, bid writer, or sales engineer at a vendor company. They receive an RFP from a buyer, log into Loopio, and use the content library to draft their response.

In Strutter, that person is a procurement manager, department head, or operations lead at a buying organization. They create an RFP, invite vendors, wait for responses, and use Strutter to score and compare what comes back.

Neither tool is better. They solve different problems for different people.

Feature comparison

The buyer workflow gap

If you are running a procurement process, the workflow you need looks like this:

1. Define what you need and generate an RFP
2. Invite qualified vendors
3. Collect structured responses
4. Score responses against your criteria
5. Compare vendors on the same dimensions
6. Make a defensible, documented decision

Loopio does not support any step in that workflow. It was not designed to. The buyer workflow gap is precisely what Strutter was built to fill.

Strutter's AI generates the RFP from your description, creates the vendor portal, auto-scores every response on submission, builds the comparison matrix automatically, and produces a recommendation when scoring is complete.

The vendor workflow

Vendors submitting through Strutter's portal do not need a Strutter account. They receive a secure link, answer questions in a structured form, and submit. They can use Loopio, Responsive, or any other tool to prepare their answers before submitting.

If your vendors use Loopio to respond to RFPs, and you use Strutter to create and evaluate them, the two tools work together without conflict.

Pricing

Loopio pricing is not publicly listed. Estimates are based on industry reports and user reviews. Strutter pricing is published at strutterai.com/pricing.

What Strutter does not do

Honest comparisons include limitations.

• No content library for managing vendor answers. Strutter is not a response management tool. Vendors who need a content library should use Loopio or Responsive for that purpose.
• No CRM integration. Strutter does not currently connect to Salesforce or HubSpot.
• No multi-stage evaluation. Strutter supports single-round evaluation. Organizations that run shortlist rounds and final evaluation rounds separately will need to manage those stages outside the platform.
• English only. Multi-language support is not currently available.

If any of those gaps matter for your process, better to know before signing up.

Who each tool is for

Choose Loopio if:

• You are a vendor with a large, active proposal team
• You respond to a high volume of RFPs and need reusable content
• You manage multiple proposal types: RFPs, security questionnaires, DDQs
• You need collaboration tools across a distributed response team

Choose Strutter AI if:

• You are a buyer who creates and issues RFPs
• You want AI to generate structured RFPs from your requirements
• You need automated scoring, vendor comparison, and documented decision-making
• You want to start without a sales process or annual contract commitment

Frequently asked questions

Can Loopio be used to create RFPs? Loopio is a response management tool for vendors. It does not offer RFP generation, vendor evaluation, or buyer-side scoring.

Does Strutter have a content library like Loopio? Strutter has a Question Library for buyers building RFPs and a Q&A Library for vendors who respond through the portal. These serve different purposes from Loopio's content library, which is built for managing pre-approved vendor answers at scale.

Can a vendor use Loopio to respond to an RFP created in Strutter? Yes. Vendors can use any tool to prepare their answers before submitting through Strutter's portal. The two tools are not in conflict.
