Proposal Monster: Taking deals from "good enough" to deal-winning

Proposal Monster is Mentor Group’s AI-powered tool that helps sales teams transform proposals from “good enough” to deal-winning.

Sellers upload their proposal, answer a few simple questions about the buyer, and receive a detailed report on how to strengthen alignment to goals, challenges, and objections.

Built on Mentor Group’s Infinite Selling® framework — and fully customisable to each organisation’s methodology and data — Proposal Monster provides clear, actionable feedback that improves proposal quality, accelerates deal cycles, and increases win rates.

The result: sharper proposals, cleaner pipelines, and forecasts that leaders can trust.

The Problem

Good looking doesn't mean deal winning.

Salespeople invest huge amounts of time creating proposals — but too often, they fall short when it matters most. These proposals are:

• Too generic, missing the buyer’s true context.
• Not addressing the client's goals, challenges, or objections.
• Professional on the surface, but not persuasive enough to move a deal forward.

The result? Proposals that feed the Mirage Pipeline — forecasts look healthy on paper, but deals stall when they should close.
