Cust (formerly AskToSell) vs AI Proposal Builder

Cust deploys AI Retention Agents that monitor your entire customer portfolio for churn risks and expansion signals. Each agent connects to your CRM, email, calendar, and data sources to deep-research accounts continuously. It drafts retention actions you can review and run in one click, from QBR briefs to renewal proposals. The product evolved from AskToSell, which originally focused on autonomous small-deal sales automation.

Where platforms like Gainsight and ChurnZero expect months of implementation and rigid if/else automation rules, Cust positions itself around adaptive, goal-based retention agents steered with plain language. The homepage contrasts legacy customer success platforms that need consultants and certification courses with one-click actions that go live the same day. You connect data and get a prioritized portfolio newsfeed rather than another dashboard with surface-level health scores.

Customer success managers and retention engineers who manage hundreds of accounts but can only give real attention to their top tier are the core audience. Cust targets teams trying to increase net revenue retention without hiring more CSMs per account. Plans scale from 100 protected customers on Foundation to 500 on Growth, with unlimited seats on every tier.

AI Proposal Builder is Qwilr's free sales proposal generator that turns a company website URL into an interactive proposal draft. Paste your site, and the tool scans your messaging, offering, and design style, then builds a prospect-ready page using patterns from over 1 million proposals on the Qwilr platform.

Generic proposal templates make every deal look the same. AI Proposal Builder starts from your own website content, so the first draft already matches your brand voice. You can add videos, dynamic pricing cards, and ROI calculators in Qwilr's editor after generation, which is a different workflow than filling a static PDF template from scratch.

Sales reps, agency owners, and SaaS sellers use it to skip the blank page when pitching new deals. Generation is free without a Qwilr account, but editing and sending requires signing into Qwilr, where paid plans start at $35 per user per month on the Starter tier.
